Issue What is included when the PIR option is ordered? Environment SE7300 series controllers Cause The SE7300 series controllers can be ordered both with and without the PIR option Resolution If the PIR sensor functionality is ordered as included from factory, code 55 (example: SE7600A5545E) should be used. If PIR functionality is not required, code 50 (example: SE7600A5045E) should be used. PIR functionality can be retrofit at any time. For details and part numbers, please see related documentation.

Issue Is it possible to configure the On/Off output as a PWM output? Environment Viconics SE7200 SE7200C5545W Cause In some applications its desirable that the output is configured as PWM. Resolution The main On-Off outputs cannot be set as PWM, they go up to 8 CPH. However, the BO5 output can be On/Off (4 CPH) or PWM (10sec. cycles).

Issue What is the default BACnet Priority of the SmartStruxure Lite. Environment SmartStruxure Lite Cause Different BACnet devices write in different priority. Resolution The default priority is 10 in firmware version 2.4.x and newer. The default priority is 08 in firmware version 2.3.x and older.

Issue Default IP address of a SmartStruxure Lite MPM Product Line EcoStruxure Building Expert Environment MPM Cause What is the default IP address of a SmartStruxure MPM? Resolution Out of the box, the default IP is 10.50.80.3 subnet mask 255.0.0.0 This should be changed to suit the project requirement. Log into the controller using the default IP address. Edit the Ethernet setting, changing the IP address, Subnet Mask and Default Gateway. Click save.

Issue Is there any way I can transfer a value between 2 LUA programs without using a BV or AV? Example: A Lua program (PG1) is created to turn on lighting, a variable called LightOn is created but other Lua programs PG2, PG3, PG4 cannot reference the "LightOn" variable. Is there any way a variable from one Lua program can be accessed from another Lua program? Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Lua programming Cause Each PG script has its own dedicated environment, which basically means variable names cannot be shared between scripts. The only things that can be referenced are actual objects (AV, BV, etc.) Resolution An AV or BV object will need to be created within the EcoStruxure Building Expert controller to store the value and make it available for other programs to read. For example a BV1 could be created and read from or written to by multiple Lua programs by referencing ME.BV1 For more information, please reference the EcoStruxure Building Expert Software - User Interface Guide document on the Exchange.

Issue Is it possible to configure a SE7200F5545E to be used with an external CO2 sensor input? Environment SE7200F5545E SCD110 Cause Customer requesting a CO2 input and read out of CO2 value. Resolution Unfortunately this is not an option on the SE7200F5545E controller. See SE7600 series where this might be possible in some applications.

Issue Not all features are seen when a BMS platform is viewed using remote control software e.g. RealVNC Environment Remote Control Software. Cause Not all features are seen when a BMS platform is viewed using remote control software. One example is: When the SmartStruxure License Software application is used, the drop down menu for adding the license detail is not available when viewed remotely using RealVNC. Resolution When the SmartStruxure License Software application is used, the drop down menu for adding the license detail is not available when viewed remotely using RealVNC. The above example is one scenario. There are a number of other remote control software applications where similar instances may occur. If such an issue occurs, check that the BMS software is functioning correctly by both being viewed and ran in the same environment. Because of the number of different remote control software options that are available, anomalies will prevail.

Issue Which frequency is used by the Zigbee wireless communication protocol used in the SmartStruxure Lite? Product Line EcoStruxure Building Expert Environment SmartStruxure Lite SE7000 Zigbee Cause 2 different versions of Zigbee (W and P) are used, depending on generation of product. Resolution   W and P are using the same layer IEEE 802.15.4 at 2.4 GHz frequency, only the "language" is different. (they can't talk to each other) For more information and details on the different Zigbee protocols, please see: Zigbee on Wikipedia Zigbee Alliance

Issue There is no way to directly connect the output of a PID loop (COx) to an analogue output (AOx) Environment MPM Programming of PID loops Cause Analog Outputs (AO) do not appear in the drop-down list for the Manipulated Variable parameter of the PID Controller. If you bind the output to an Analog Value (AV), the AV has no reference parameter to bind to an AO. Resolution Use a Lua Program (PG) to write the AV to the AO. e.g.  if PID controller has AV8 as its Manipulated Variable, the following one line program will write AV8 to AO2 :   ME.AO2 = ME.AV8

Issue What firewall port no's used by the MPM controllers need to opened on a PC or router Environment Routers Firewall Cause What port numbers are required to be opened on a router or firewall? Resolution For browser to MPM communication, port number 80 (TCP) needs to be open. For BACnet over IP communication, port number 47808 (UDP) (configurable in the MPM) needs to be open. For Modbus over IP communication (future), port number 502 (TCP) needs to be open.

Issue The AO output on the SE7600 controller is either off or on instead of modulating. Environment SE7600F Room Controller Cause The SE7600 Room Controller is expecting a Discharge Air Sensor to be connected in order to detect minimum heating temperatures. While this is missing it will not modulate the heat based on room demand. Resolution Install a 10k Type 2 Discharge Air Sensor between the DS an Comm terminals or add a 10k resistor to allow the unit to modulate heat based on room spacetemp.

Issue Can you disable the wireless in StruxureWare Lite Environment StruxureWare Lite site with wireless devices Cause Does the MPM emit radio waves if the Enocean & Zigbee is not configured (enabled) in the controller set up pages Resolution ZigBee is a wireless communication protocol that uses a mesh network between devices. It operates on the 2.4GHz band and is divided in 16 channels. The Zigbee Pro protocol has error-correction and can dynamically add or remove nodes to the mesh without interrupting the communication. A MPM set as a ZigBee Coordinator creates a network (more or less like a wi-fi router) and a MPM set as a ZigBee router will join an existing network. As a rule of thumb the practical distances are around 150ft in building and 300ft open air but heavily depends on the obstacles around. Disabling ZigBee through the Communication Configuration (C2G1) object will prevent data exchange between this MPM and the rest of the network. It will not disable the radio module, which could still be connected to a network. EnOcean is a 'broadcast' type of protocol that operates on 3 frequency bands. North America is currently using 315MHz and will soon be replaced by 902MHz. Europe operates on 868MHz. As a rule of thumb, the practical distances are about 50ft in building but heavily depends on the obstacles around. There is no way to disable the EnOcean module, however if no device is added or no reference to EnOcean commands are used in the scripts, the module will not transmit or receive packets.

Issue Does StruxureWare Building Operation support oBIX protocol natively? Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment   oBIX Cause In Knowledge Base articles as well as some other sales documents, it shows SmartStruxure as compatible with Obix. Resolution StruxureWare Building Operation does not have built-in native support for oBIX, but there is a gateway product that can talk oBIX.  

Issue Is there a modulating output available in the SC3000 relay pack?  Environment SC3000 Cause In some applications, a modulating output is requested. Resolution Unfortunately, no such output is currently available in the existing version of the SC3000.

Issue Dashboard may freeze when adjusting a text field smaller than the content on a monitoring tab  Environment Windows 7 Cause Earlier versions of firmware in the MPM may have this condition Resolution Upgrade from version 2.8 to version 2.10 in the MPM

Issue What is the maximum load on MPM-UN analogue Output? Environment MPM-UN SmartStruxure™ Lite Multi-Purpose Manager Cause Avoid overload on output ports Resolution The analog output ports has a maximum nominal load of 50mA each.

Issue Internal time schedules in the SE8300 and other 8000 series room controllers. Environment Schneider Electric SE8xxx Cause As of the time this article is being written these devices are intended to be controlled by a network management controller or using contact closure on the device. However, some sales documentation states that these devices have "7 day occupancy scheduling (2-4 events)". This documentation was released prematurely and, although future models will have this capability, as of March of 2014 the current models do not. Resolution Currently occupancy of the SE8xxx devices can be controlled by a network variable over the Lon, BACnet or ZigBee network. Alternatively, occupancy can be controlled by configuring the device for contact closure control of occupancy. Future model series SE8xxx devices will support scheduling. Note, however, that it will not be possible to upgrade older devices to support scheduling since the hardware will also be changed.
