Issue Upgrading the MPMs firmware through the boot loader was unsuccessful. 10.50.80.2 is pingable, but not the default IP 10.50.80.3. The LED's keep blinking in tandem (alternating one after the other), even after having the MPM powered over 10 seconds. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager Cause This can be triggered by multiple events: - MPM was interrupted (powered off) while the firmware was still being upgraded. - Database does not exist; MPM was formatted and does not have firmware installed. - Database is corrupt (for any reason) Resolution It is strongly recommended that a firmware upgrade be done via the "File Manager" tab in Building Expert. However, if this is not possible, an upgrade can be performed through the bootloader using the following steps: 1 - At the top left part of the screen, make sure "Status" says "Connected". 2 - Format the SD card clicking on the "Submit" button next to "File System Format". "Format Done" will be displayed next to the button once the format has been completed 3 - Click on the "Browse" button and Navigate to the Firmware_update_V2.XX.bp" on your computer then click on "Submit Query". 4 - The previous step will upload the firmware file to the MPM's SD card. Once the file has been transferred, the following message will appear: or 5 - The MPM Must be kept powered-up for at least 15 minutes in order to allow the MPM some time to unpack the firmware file. The best way to determine whether the MPM is back online is to ping its IP address using a "Command Prompt" window. 6 - Once the MPM replies to the ping, Building Expert can be accessible though 10.50.80.3   If the above solution does not work; meaning that every time a new firmware is pushed to the MPM, the MPM keeps coming back to the bootloader, contact technical support

Issue Definition of number of nodes and points allowed using Modbus TCP/IP or RTU xdriver. Product Line Andover Continuum Environment Modbus Protocol Cause Definition of number of nodes and points allowed using Modbus TCP/IP or RTU xdriver according to the modbus protocol. Resolution The maximum number of nodes is 254. The address range for points is 1 through to 65535. The number of addresses is limited by the controller memory. We have had ~6000 points but please note the Modbus is a polled protocol so the more points you have the longer the poll rate.   Specific Modbus RTU Details Our Modbus RTU XDriver supports the node range from 0-255. According to the Modbus specification, the node range is from 0 – 255, with 0 being the master, 1-247 being the slaves, and 248-255 being reserved addresses. After 32 nodes (1 master + 31 slaves), you may need RS-485 repeaters to ensure proper communications. This depends on a number of different items, including if the RS485 transceivers are full or quarter load. You can find the Modbus serial standard at the link below for further details. http://www.modbus.org/docs/Modbus_over_serial_line_V1.pdf

Issue Lost MPM IP address Product Line EcoStruxure Building Expert Environment SmartStruxure Lite MPM Cause Forgotten IP address Resolution 1. Connect your PC directly to your MPMs Ethernet port and set your computer network configuration to access the MPM at the default address of 10.50.80.3 (example, set your PC to use address 10.50.80.99). 2. Disconnect and re-connect power to MPM. 3. The MPM goes to Bootloader mode for approximately 10 seconds at start-up. You will see Blue and Green indicators (UN2/VA2 MPMs) alternate steadily during that time according to the following. a. While the MPM is in Bootloader mode, you can access your config.db file at 10.50.80.2/root/ config.db. b. Enter address in browser window before you restore power to not to miss the 10 second window. It may require more than one refresh attempt before you enter Bootloader. 4. The browser prompts you to open or save config.db file once successful connection is made. 5. Open file using text editor. 6. Search “ETH1_ip” field for IP address of your MPM to right side of “ETH1_ip”. 7. Enter IP address to browser address bar to access your MPM.

Issue Will the Multi-Purpose Manager (MPM) act as a BACnet IP BBMD?   Product Line EcoStruxure Building Expert Environment Site using BACnet and one or more  SmartStruxe Lite Multi-Purpose Manager (SSL MPM)  Cause Can the MPM act as a BBMD Resolution The MPM cannot act as a BACnet Broadcast Management Device (BBMD), but it can be a foreign device to another BBMD BACnet protocol includes broadcast traffic which does not pass through on-site routers. For BACnet devices to network across a wide area or across multiple separate sites connected by the Internet, it is necessary to register the BACnet devices with a Schneider BBMD using the Foreign Device Registration function in Building Expert. For a Multi-Purpose Manager (MPM) running Building Expert to function as a BACnet device, when being managed remotely over a standard TCP/IP network, it must be configured as a Foreign Device. It must also be registered on an Automation Server (AS) on the remote network that acts as a BBMD. Once done, BACnet devices can send messages to the BBMD, which are translated by the BBMD so they can pass over a standard on-site router. Then BBMD forwards the messages to the appropriate destination MPM controlling the Devices for which the BACnet messages were originally intended. Then the MPM translates the messages received over the network from the BBMD into standard BACnet messages and passes them on to the intended Devices as if they were direct BACnet messages. This Foreign Device Registration feature allows a single user with a StruxureWare Building Operations (StruxureWare Building Operation) terminal to remotely oversee multiple disparate sites simultaneously using BACnet, without having to install expensive direct connections to each site. You must have Firmware release version 2.9 or higher installed on your Manager to use Foreign Device Registration function. Here is the BACnet-Specifications-PIC-Statement.pdf And the  explanation on how to setup the DR-ForeignDeviceRegistration.pdf

Issue Unsure what options are available in the Lua smtp.send() function. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause The Lua smtp.send() function is not fully documented. Resolution The syntax of the smtp.send() function is: smtp.send { from = string, rcpt = string or string-table, source = LTN12 source, [server = string,] [user = string,] [password = string,] [port = number,] [domain = string] }   From above you can see that the "from", "rcpt" and "source" fields are required. Whilst "server", "user", "password", "port" and "domain" fields are optional. Example Lua code is: --============================================================================== -- SSL email notification script example --============================================================================== -- Define the input you want to monitor below var("temperature", "ME.AI1") -- Room Temperature limit = 78 -- define the threshold now = scl.sysclock() if (temperature > limit) then -- When temperature is above threshold     if (sent == nil) -- Check if e-mail was already sent     and ((last == nil) or (now - last > 15 * 60)) then -- Maximum every 15 minutes         sent = true -- Only send e-mail once         last = now -- Keep track of last time     result, reason = smtp.send {     user = "alerts@server.com",  -- Enter your existing SMTP username     password = "test1234",  -- Enter your existing SMTP password     from = "alerts@company.com",  -- Enter your existing Source address     rcpt = {             "user1@company.com",  -- First recipient             "user2@company.com",  -- Second recipient             "user3@company.com"  -- Third recipient             },     source = smtp.message( {     headers = {     from = "alerts@company.com",  -- Displayed source address     to = "technicians@company.com",  -- Displayed recipients     subject = "Temperature Alert"  -- E-mail title                 },     body = "Current temperature is: " .. temperature ..

Issue Having difficulties binding (pairing) room controller with MPM Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) SE7000 Room Controller Cause Unable to make sense of LED blinks status Resolution The room controller cover needs to be removed to expose the LED located on the ZigBee communication module.   Here is a description of the LED status for Sigma Room Controllers (SE7000 Series): Blinks once: ZigBee Communication module is powered but might be defective or incompatible with the room controller base board. Blinks twice: ZigBee Communication module is compatible with room controller base board but cannot see any ZigBee network in its range that matches its own channel and PAN ID. Blinks 3 times: Room controller has joined the network successfully but it is not bound to MPM. Blinks continuously: Room Controller has joined the network and is placed in identify mode by MPM during the binding process. Blinks 4 short and 1 long: Thermostat is bound to the MPM and is communicating.

Issue Some Modbus meters can be integrated to a MPM using the built-in widgets (MOD1 checkbox enabled).  Other Modbus meters require a LUA script. With LUA scripts, the MOD1 object (Modbus config) must be disabled (MOD1 checkbox disabled). Can two Modbus meters be integrated to the same MPM, with one using the built-in widget and the other using a LUA script? Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Modbus devices Cause Unfortunately, both meters must be integrated with LUA scripts or both must be integrated via built-in widgets. By keeping the internal Modbus driver enabled (MOD1 checkbox enabled), the Modbus component in the script will not work.  The two will conflict. Resolution The two Modbus meters must both be integrated via LUA script or by built-in widgets.

Issue The PID controller object provided as part of the MPM software does not allow for any means of programmatic override i.e. forcing the loop output to 0%, 100% or other user defined position.  If you force the referenced Manipulated Variable (output) to a particular position by programmatically disconnecting it from the PID object, there can be a large overshoot when the PID output is reconnected.   Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause If you force the referenced Manipulated Variable (output) to a particular position by programmatically disconnecting it from the PID object,  the PID controller will be 'open loop' and any integral parameter will wind up the output to its max or min position.  This can cause a large overshoot when the PID output is reconnected.   Resolution One option is to write a Lua script that forces the Controlled Variable and the Setpoint Reference to receive the same value when you override the loop output. This would freeze the output of the PID controller and prevent any integral wind up. There would still be a 'bump' when you remove the override, but it should be reduced.   Another option is to replace the PID controller object with a Lua script that provides the same the same functionality but with the addition of an override mode. You can find a sample Lua script here

Issue How to manage the trend files stored on the SmartStruxure™ Lite Manager flash memory. Examples and guidelines for the FTP transfer of trend files. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) 2.4.3 and above Lua program Cause All data points collected by a TL object are saved in a text file stored on the SmartStruxure™ Lite Manager SD memory card (which has a storage capacity of 2 GB). This file is accessible at [ipaddress]/root/data/trend.csv. The trend.csv file contains the log of all TL objects on a SmartStruxure™ Lite Manager. It logs new data until it reaches a size of ~10 MB, when it will be renamed trend_date.csv for backup. A new trend.csv file will be created to record the new data.  In the context of your application, it may be of interest to retrieve the trend.csv file from the SmartStruxure™ Lite Manager for analysis.   It is also important to remove these excess trend files since there is a risk of filling the SD card on the Manager. An example of storage requirements are listed below: A Manager with 10 trend logs recording data every 10 minutes will record ~50 kB of data each day, for a total of ~350 kB per week. A Manager with 20 trend logs recording data every 30 seconds will record ~2 MB of data each day, for a total of ~14 MB per week. Resolution The simplest way to automate this process is to use a Lua script to initiate a FTP file transfer to an FTP server on an event of your choice. The example shown in the application note below, the file transfer is initiated by a SmartStruxure™ Lite scheduler. Once the file is transferred to the FTP server, you can rename the file to create a backup. Data collection will then continue in a new and empty trend.csv file. This way, any new transfer of the trend.csv file to the FTP server will be a complement of the preceding file. This application note discusses the management of the trend files stored on the SmartStruxure™ Lite Manager flash memory, and provides examples and guidelines for the FTP transfer of these files. Lua script examples can be found here

Issue Maximum Limits for SmartStruxure Lite Design (Scalability, Capacity) Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause What are the maximum number of communication between managers and end device Resolution Guidelines: number of end devices per node Wired ● 6 wired inputs (Ohms / Volts, Analog or Digital) ● 6 wired outputs (4 analog 0-12VDC, 2 digital) The analog output ports has a maximum nominal load of 50mA each. ● Need more? Modbus I/O extenders, SEC-TE, etc. Wireless devices ● In theory: almost unlimited (no physical constraints) ● In practice: limited by range and strength of wireless signal     ● EnOcean: Rule of thumb is within room (up to 75ft in building – line of sight)     ● ZigBee: Rule of thumb is within room (up to 150ft in building – line of sight)     Limited by application     ● Frequency of transmission     ● Efficient handling of data queues Guidelines: number of end devices per node BACnet - with the current basic client capabilities, the maximum number of devices supported on a single BACnet network is 1000. Modbus      Limitations for ModBus connectivity per MPM is 31 devices but depends on polling rate and amount of points:         ● Using pre-defined objects, polling rate is 30s / device         ● Using Lua script, polling rate variable ZigBee or EnOcean for the end devices? ZigBee ● Longer range ● Reliability built-in the protocol (ack, retries, …) ● Requires a battery ● Multiple channels available (possible to isolate networks / groups) EnOcean ● Self-powered (no battery) ● Easy to deploy ● Lower range ● Reliability must be ensured at the application level ● No retries ● ZigBee coordinator is a device that sets up the network, is aware of all the nodes within its network. Every ZigBee network must contain a network coordinator. ● ZigBee router can act as an intermediate router, passing on data from other devices. ● ZigBee end-device is part of the network, but doesn’t re-route information to neighbors. How many devices can I use? ZigBee ● A ZigBee network should not have more than 75 ZigBee devices in total (coordinator, router and end devices); ● A ZigBee network should not have more than 24 ZigBee routers (+1 coordinator) ● A ZigBee node (coordinator or router) should not control more than 10 peripheral end devices. EnOcean ● Using pre-built objects: ● 4 Thermostats ● 20 Switches ● 20 Relays ● The maximum number of devices added to each MPM is 49 ●The maximum number of EnOcean devices added to each MPM is 49 ●The maximum number of EnOcean devices with the same EEP added to each MPM is 49 .This only applies to firmware 2.13.1 and later, the limit for previous firmware is 20. An Exception is the following limits for devices/widgets per MPM: 20 EnOcean Switches 20 EnOcean Relays 4 EnOcean Thermostats The AV and BV variables The MPM-UN controller comes with 100 AV's and 100 BV's. MPM has capacity for up to 700 AV's and 700 BV's. After the initial 100 are consumed, add Value Banks of 100 for each AV and BV. Value Banks will be added as sub-devices under the main MPM.  Maximum data Points: MPMs can have up to 750 data points per monitor. What is the maximum size for background graphics? The maximum size of a background picture (in dashboard or section map) is 2Mbyte with a maximum resolution of 1920 x 1080 (Width x Height). For analog inputs with a signal range in Ohms has no reading limit. You just need to configure the table in the AIC object assigned to referred input.

Issue Unable to monitor a SmartStruxure Lite MPM controller over a Building Management System using BACnet to an AX BMS Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause Misconfiguration of BACnet settings on a MPM controller. Resolution Open Building Expert on the controller with a supported browser. In this example both the MPM controller and the BMS system are in the same IP subnet range. Highlight the Device's name e.g. SmartStruxure Controller and go to the Configuration tab. On Ethernet Settings (ETH1) The IP address of the MPM controller must be in the same subnet IP range of the BMS IP address, but not the same IP address. Netmask must be the same subnet on both controllers (MPM and BMS) e.g. 255.255.255.0, if not then a BBMD/Foreign Device needs to be used. Gateway IP if used. On BACnet Settings (BAC1) Network ID (171) used on the MPM controller must be different than the BMS network numbers used for BACnet MS/TP and BACnet IP Set Protocol to BACnet IP Click on the upper-left icon (Save database to flash) Important! Right-click on "SmartStruxure Controller" then on "Restart Controller," be patient. On the BMS Jace AX, under BACnet network, click on Discover, uncheck all MPM Networks assigned within the MPM (if this facility is available in the BMS), in this example we have only one, it’s #171, refer to point 4. If you don't uncheck MPM network number, the devices will still discover but with duplicates. In this example, network #1 is the BMS IP network and needs to be checked. Network #300 is the BMS MS/TP network number, and has no impact on discovering the MPM as a BACnet device. Click OK. Here’s the result of the discovery, all the objects we had at point 4. are shown. Now add the Devices to the Database, then select one device (in this example the SE8600 is selected), click the Discover button, all objects we had in point 4. are now in AX. Add them to AX database.

Issue Points from a SmartStruxure Lite MPM display the question mark character (?) instead of the correct engineering unit when brought into Building Operation via BACnet. Product Line EcoStruxure Building Expert, EcoStruxure Building Operation Environment Building Operation WorkSation SmartStruxure Lite MPM with firmware version 2.5.8 or earlier Cause The question mark (?) placeholder for units is used when Building Operation reads a BACnet unit id that we do not have a translation for to Building Operation units. In MPM firmware version 2.5.8 and earlier, units are translated as vendor proprietary, in firmware version 2.7 and later the units are translated to standard BACnet units. Resolution Upgrade the MPM firmware to Version 2.7x or later. MPM firmware can be downloaded from the https://ecoxpert.se.com/building-expert/discover#tab/documents . Please note that firmware is on a secure area of the site that is only accessible to certified SmartStruxure Lite engineers.   I M P O R T A N T   Also, any thermostat where the communication module is replaced must be re-addressed and re-discovered, additionally all related Widgets will have to be re-linked to the new object(s). If you are not sure which module you have on your SE7000P units do the following... a) Remove the cover. b) look at the part number, the new extended profile modules are 051-0132

Issue How to create a Binary Input or Digital Input on a MPM controller Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause When a Binary Input is created, the object does not work. There is no documentation on how to create a Binary Input Resolution In order to use a Binary Input, both the BI object and the corresponding Analog Input AI object must be added from the object list. For example, if you need to use BI3 with a dry contact, you will also need to add AI3 and toggle its "input type" to Ohms, then save the object. You also need to keep the object in the object list. With regards to “Input type” for the Binary Inputs: (the "input type" property is in the AI object) -When set in Volts, anything >= 2VDC will be considered a 1 status.                                    anything < 2VDC will be conspired a 0 status. -When set in Ohms, anything < 10kOhm will be considered a 1 status.                                      anything >= 10KOhm will be considered a 0 status. Note: When "Input type" is set to ohms, a dry contact must be used for the BI to work properly. BO1 and BO2 of the MPM can be used for example, but not the relays of the TE2 as they are not dry contacts by design.

Issue Unsure how to use the settings in the VAV Flow object Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) MPM-VA Cause Cannot change the units of the output Resolution For Variable Air Volume (VAV) Flow configuration, it is recommended to use the Kf method when setting up an MPM-VA In the PFC calculation, the Kf factor represents the flow (Q) for a measured dP on the flow ring of 1 Pascal (Pa). The flow sensor on the MPM controller (AI21) measures dP in inches of water column (in w.c.). With a conversion of 1 in w.c. = 250 Pa, we obtain this formula: Kf = Q [cfm] / (sqrt(250 x dP[in w.c.])) or, Q [cfm] = Kf * (sqrt(250 x dP[in w.c.]))   Calibration/Balancing: A typical VAV box should have a theoretical Kf factor provided by the manufacturer. This Kf value must be used in the in the PFC object when balancing VAV systems. Next, using instruments such as an air flow capture hood, technicians must compare the output flow from the PFC object and the actual measures air volume. If the values do not match, the measured value along with the value of AI21 must be entered in the above equation to produce a new Kf factor. The new Kf value will then be used in the PFC object to finalize the calibration For example if the measured air volume is 200 cfm and AI21 is 1.2 w.c., the new Kf will be: Kf = 200 / (sqrt(250 x 1.2)) =11.55 Important notes: -Even though the Kf units show "Liters per second", the "Flow output value" will be in "Cubic feet per minute" (CFM) if the value of Kf is based on CFM values. If the Kf is based on LPS, the output will be in LPS -Every time the Kf factor is changed in the PFC object in the MPM, it will take up to 2 minutes before the output flow changes to the new value

Issue There are two variables: INDIT =0 koll1_p=1 - When using AND: DEV700.BO1=(INDIT and koll1_p) --prim sziv1 The result is DEV700.BO1=1 - When using *: DEV700.BO1=(INDIT * koll1_p) --prim sziv1 The result is correct DEV700.BO1=0 Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) Cause The simple issue here is that the and keyword is a logical operator, however the variables being compared are numeric. Contrary to many other languages, a Lua variable is not typed, which means that the kind of value it stores are not constrained and can actually change during a program execution: Boolean Designates a variable which can hold the true or false values. It is important to note that true or false are not numbers and do not equal 1 or 0. That is why the mathematical multiplier * keyword works in this instance but the logical and does not. Resolution The logical operators are and, or, and not. Like control structures, all logical operators consider false and nil as false and anything else as true. The operator and returns its first argument if it is false; otherwise, it returns its second argument. The operator or returns its first argument if it is not false; otherwise, it returns its second argument: print(4 and 5) --> 5 print(nil and 13) --> nil print(false and 13) --> false print(4 or 5) --> 4 print(false or 5) --> 5 Both and and or use short-cut evaluation, that is, they evaluate their second operand only when necessary. Essentially to use the and operator with numeric values they will first need to be evaluated into true or false states. For example: If INDIT ~=0 then x= true else x= false end If koll1_p ~=0 then y= true else y= false end DEV700.BO1=(x and y)

Issue What files are saved, to where and why is this used. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager (MPM) All variants: VA, UN, GW Cause The running database of a SmartStruxure Lite MPM controller is in the controllers volatile memory (RAM), in order for this data to be preserved during a power failure or reboot this needs to be saved to non volatile memory (Flash) Resolution The save period is for backing up the controller database to flash memory, this can be set to Never, Hourly or Daily. All programming and runtime information is then saved to the controllers flash memory so that it is not lost during a power failure or controller reset. Stored data includes Controller status, configuration changes, updates such as trended information or setpoint changes, and Lua scripts.

Issue Unable to connect to a BCX configuration page Product Line Andover Continuum Environment Continuum BCX9640 and 4040 Cause 404 Page not found error accessing the configuration page using the controller IP in a browser Resolution Note: This document is for troubleshooting help, it is not a comprehensive BCX setup guide. Please refer to the BCX1 Technical Reference for detailed setup instructions.   Using a LAN or a cross-over cable? If the BCX is on a LAN and was working before, remove the LAN cable from the BCX and try to ping the BCX. If you get a response then you have a duplicate IP. Same subnet? Make sure DHCP is disabled on your computer. Use a straight-through or cross-over cable to access the BCX directly. Has this cable been used successfully before? Reset the BCX to the default IP. The button is under the cover, top right. Be sure to hold down the IP reset button for about 20 seconds Is the controller in bootloader mode? This can be seen by observing the CPU light flashing rapidly, approximately two times a second (2 Hz at 50% duty). Flashing the application through Cyberstation may fix this and enable you to get back into the controller. Even though access to the config page is not available, the update OS button in Continuum using the controller's Network setting and ACCNet ID may be accessible to perform a firmware upgrade. Ping the IP from a DOS prompt, can the BCX be pinged? Ex. Ping 169.254.1.1 Use Ipconfig /all to see your PCs network settings. The best case scenario is to be on the same subnet or connect directly. Are there multiple NIC cards on the PC? (Ex. Ethernet and wireless on a laptop) Disable the wireless adapter or other adapters. Continuum does not support a multiple NIC card configuration. Run Wireshark to get a capture between the BCX and The PC. Remove power from the BCX and reapply power. When the BCX starts it sends a gratuitous ARP that will indicate the IP address within the BCX. It may be a different IP than expected. Did the issue of not accessing the web page happen after a power outage? Is the CPU light flashing amber and it was flashing green before and no one has flashed the controller? Is the CPU light solid amber? If so, contact support for assistance.

Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Cause In this case, the Modbus holding register is a 16-bit unsigned value that is used by the Modbus device to represent two individual 8-bit values.  The 16-bit unsigned value is an integer with a range of 0 to 65,535 and needs to be converted into two analog values. Resolution Use a Building Operation Modbus Analog Input Point for each value required.  Each object will be configured to read the same Modbus register address with the bitmask value applied before evaluating the value to determine the output. For example: Read Modbus holding register 40001 which is a 16-bit unsigned value and decode as two analog values. Under the Modbus device object - create a Modbus Register Group Under the Modbus Register Group - create two Modbus Analog Input Points Configure each point as follows: Modbus Analog Input Point 40001 (AI-HighByte) Register number 1 Register type 16-bit unsigned Read function code 03 Bitmask - enable all bits 8 through 15 Modbus Digital Input Point 40001 (AI-LowByte) Register number 1 Register type 16-bit unsigned Read function code 03 Bitmask - enable all bits 0 through 7 Additional information can be found in the Building Operation Technical Reference Guide - Modbus Point Configuration (Bitmask) or WebHelp at Point and Value Configuration
