Issue Continuum errorlogs from i2 controllers show many 1465 CRC errors for each controller. There is no other information, warnings, or errors logged. Product Line Andover Continuum Environment Continuum 1.81 CX9900, 1.52000022 I2, 3.x Cause Some controllers with special firmware contribute to 1465 CRC errors greatly. Resolution Upgrade CX controller to latest firmware version 1.53000026. For more detail about 1465 CRC, refer to What do CRC errors (1465) indicate?

Issue What voltage do the following Drayton Theta YB Actuator variations work with and what features do they have? Environment YBL1 YBL1A YBM2 YBM2A YBL3 YBM3 Cause What voltage do the following actuators work at? What does each actuator have? Resolution YBL1 = 24vac + Potentiometer YBL1A = 24vac + 1 Auxiliary Switch + Potentiometer YBM2 = 230Vac YBM2A = 230Vac + 1 Auxiliary Switch YBL3 = 24vac + Changeover Limit Switches (Transfer Switch) YBM3 = 230vac + Changeover Limit Switches (Transfer Switch) Note: see diagram for difference between Changeover Limit Switches and Auxiliary Switch. For the Drayton Datasheet and YBM2 and YBM2A actuator, all valve replacements and valve to actuator linkage kit part numbers, see What is the replacement for a Drayton Theta YBM2A Valve Body / Actuator assembly? For the other actuators ensure the correct voltage actuator is selected: YBL1 = MD10B-24 or MD20B-24 YBL1A = MD10B-24 or MD20B-24 YBL3 = MD10B-24 or MD20B-24 YBM3 = MD10B-230 or MD20B-230 The switch and potentiometer combinations can be replaced by the following: Changeover Limit Switches - MD-S2 Auxiliary Switch - MD-S1 Potentiometer - Belimo P140A (not a Schneider Electric part number)

Issue Is there anything that will convert AC256 drum programs to Continuum Plain English programs? Environment Cyberstation Plain English Cause When doing an AC256 to Continuum upgrade, is there a utility to convert drum programs to Continuum Plain English. Resolution Various partners and branches have written their own utility. Product Support does not distribute or support any of these. The results of most are underwhelming - PE code that looks "drum-ish" and often involves enough clean up that is better when PE is done from scratch. Alternatively, a request for improved or other utilities can be made on the Exchange Community.

Issue What is the accuracy of RTC? Product Line Andover Continuum Environment Site with controllers using the RTC Crystal Quartz chip (controllers such as the ACX) Cause What is the accuracy of Real Time Clock? Resolution When the controller is powered down, the battery-backed RTC Chip has an accuracy of +/- 1 minute per month. When powered on, the controllers use the RTC chip as a reference point but keep time in software. Experience has shown an accuracy of 1 – 2 seconds per month when controllers are offline and not re-synched from the Network. Since that is typical and not calculated, a conservative number would be +/- 10 seconds per month. When Online,the accuracy is determined by Cyberstation which can itself be synched to an extremely accurate NST Server. I2 and B3 controllers are re-synched once per hour. For Sync time in Cyberstation(s) and Server check Sync time in Cyberstation and Server. For more information see What are the differences between a hardware and a software Real Time Clocks (RTC)?. For how field controllers keep their own internal time check How do our field controllers keep their own internal time?

Issue Can an internal modem be installed in the field on a Niagara G3 ENC. If so, what is the part number? Product Line TAC IA Series Environment Niagara G3, ENC-410, ENC-520 Cause Can an internal modem be installed in the field on a Niagara G3 ENC? Resolution An internal modem can be field installed on an ENC after purchase. No license changes are required. Both the ENC-410 and the ENC-520 uses the same part number, UNC-410-MDM. Reference the Replacing the Modem section of the TAC I/A ENC-xxx Installation Instructions documents for details on installing the internal modem. ENC-410 (document #F-27415) ENC-520 (document #F-27416) Reference Configure a Niagara G3 ENC serial port for dialup modem on setting up the port for dialup modem.

Issue SNVTs that have been directly connected to a Menta application are not being updated. The value of the SNVT is not the same as the value in the corresponding Menta application. Product Line TAC Vista Environment Vista 5.1.7 Xenta 700 series Cause The Menta application is running too fast and sending to many requests out to the LonWorks network. You can see that the LonWorks network is running at very high levels if you use a LonWorks protocol analyzer. For example. 20 SNVTs are directly connected to RI in a Menta application running at Medium/Fast (500ms cycle) This would mean that every 500 ms 20 request would be processed to the LonWorks network. The 731 can only process around 15 request per second. The above example would be requesting 40 samples per second. Resolution The best solution for this problem is to use the connection object to connect SNVTs into Menta. Here is a link to User friendly way to make connections in Xbuilder for connection objects. The transfer rate can then be modified to slow down the LonWorks request through the 731. In the default setting for a connection object the transfer period is 10 seconds. To help with network request this time can be modified to prime numbers or realistic values for you application.

Issue Replaced an AC1Plus with an AC1 and the reader pattern is incorrect Product Line Andover Continuum Environment Continuum AC1 AC1A Cause The AC1/AC1A module only has 1 LED pattern which is Alternate LED pattern, there is no way to alter this. See Description of LED patterns on access readers, and how to change them for description of LED patterns. Resolution If a different LED pattern is required by the site then use an AC1 plus or an ACX57xx which gives the ability to use an alternate LED pattern. See Description of LED patterns on access readers, and how to change them for configuration.

Issue Viconics stats are only showing as offline in Continuum using the "controller status" notification when being accessed Product Line Andover Continuum Environment Continuum Viconics Stats Cause Viconics BACnet stats must be probed in order to return alarms Resolution There are 3 probe types that can be set up in Continuum. Probe, ProbeOnDemand and ProbeOff. These types can be configured in Cyberstation and in the Viconics Stat from Continuum Explorer (Edit>General Tab>ProbeType drop down selection) "Probe Time" can also be adjusted on the Cyberstation (default is 60 seconds) Testing Results Cyberstation Probe Type changed to "Probe", Probe Time=60 seconds. Viconics stat set to it's default of "Probe Off" Remove mstp connector result: no alarm until the Viconics stat is opened (This probes the device) Cyberstation Probe Type changed to "Probe", Probe Time=60 seconds. Viconic stat set to "Probe" Remove mstp connector result: alarm comes in automatically after 60 seconds Probe Type and Probe Time Definitions (Continuum Help) Consider and these options and their affects on the system when making a selection Probe - Probing occurs at the interval specified in Probe Time. The default is 60 seconds. The advantage of this is that CyberStation detects a device going offline regardless of whether or not CyberStation is attempting communications with the device. The disadvantage is excess probe traffic for devices. ProbeOnDemand - Probing does not occur unless a communications transaction with the target device fails. Once a transaction fails then probing occurs at the interval specified in Probe Time until the device comes back online. The advantage is that additional requests to the controller fail immediately. The disadvantage if that node failure is not detected until a CyberStation application needs to communicate with a controller. ProbeOff - Probing does not occur. The advantage is that there is never probe traffic to the device. The disadvantage is that each request to the device fails only after the transaction times out. Also see the following article related to Viconics stats and performance: Problems and cautions when communicating with TAC (Viconics) Bacnet communicating thermostats

Issue Obix is being used import logs from the R2, UNC-520 station into a Niagara G3, ENS. The problem is that some logs are being split into multiple histories in the ENS. A single log in the UNC is split into multiple histories when imported into the ENS. Product Line TAC IA Series Environment Niagara G3, ENS Niagara R2, UNC-520 Cause The problem is on the R2 side. The R2 web server uses multiple threads, each servicing a single HTTP request. The R2 oBIX server has a method to resolve the requested URI to an object in the station - usually a Node of some kind. If multiple requests are coming into the oBIX server at the same time, the URI resolution can be invoked by multiple threads. So if one thread resolved a URI to a particular Node, then a second thread came in and resolved a second URI to a second Node, sometimes the second Node could be used to fulfill the first request (as well as the second request). This resulted in multiple copies of the same history when brought in to the G3 ENS. Resolution Once this problem was clearly identified, the solution was simply to synchronize access to the URI. The new obix-2.301.535i.beta.jar synchronized this process to eliminate the splitting logs. Download and install the new R2 obix-2.301.535i.beta.jar file in all UNCs which archives their logs to the ENS. Reference How to install an I/A Series R2 JAR File for more information.

Issue To re-use a point in an ASC, should one delete it or just edit as needed Product Line TAC INET Environment I/NET Site Cause A point in an ASC needs to be repurposed from its original design. Resolution The point can merely be edited, provided it is available for re-use. Check closely in the functional description of the points in the specific TCON for that controller to ensure this is permitted on the point in question.

Issue When opening a Xenta Server (Xenta 5/7/913) trend log, it will display estimated value for a constant period of time. For example: A trend log trends room temperature every 30 minutes. An operator opens the trend log at 9AM, the trend log displays all the trend log values fine till 8AM. All values after 8AM before 9AM display as estimated value. Open the trend log again at 9:30AM, estimated values start at 8:30AM. Product Line TAC Vista Environment Xenta Server (Xenta 511, Xenta 527, Xenta 701, Xenta 711, Xenta 913) Cause Estimated value in trend log can have various causes. If it is always a constant period of time, it could be caused by the wrong time setting in Xenta Servers (most likely is the wrong day light saving minutes setting). Daylight saying time in a Xenta Server is set to 60 minutes by default. If Vista Server PC is set to not using daylight saying, then Xenta trend will not display the last hour trend since it believe the time is not reached yet. Resolution Please refer to Xenta Servers and Time Synchronization for step by step guide of manually setting up the Xenta Server's time. After the time setting change has been made, Xenta Server will reboot itself. When the reboot finishes, reopen the trend log and the issue should be solved.

Issue Privilege software version 2.01 crashes during installation on Windows XP. Product Line TAC Vista Environment Aladdin Privilege Administrator 2.01 Vista IV Licensing Cause Privilege Administrator Incompatibility with XP Resolution Uninstall any previous Privilege Administrator (Please see How to uninstall Privilege Administrator 2.01 software for details on uninstalling the software) Download "Privilege Windows XP crash hotfix" (PS202.zip) Install PS202 by running setup.bat. Install Privilege Administrator 2.01 again.

Issue MN-S# sensor connected to MNB-1000 showing all segments lit up Product Line TAC IA Series Environment I/A Series MNB-1000 Cause Connecting a UI to a Binary Input set as a binary type "pulse" in the MNB-1000's database will cause this. Resolution Per UI inputs of the MNB-1000 do not support pulse inputs, pulse inputs connected to an MNB-1000 must use a DI input. Correct the database so the pulse input uses one of the DI inputs. Connect that DI to a Binary Input object set to binary type "pulse." Compile and download and the issue will clear.

Issue After powering off, pressing the reset and Reset IP button a bCX1 controller still will not start up. CPU does not flash and controller will not respond to a ping. Product Line Andover Continuum Environment bCX1-CR-INF 9640 bCX1-CR 4040 Cause The controller is connected to an Ethernet network that is in a broadcast storm condition. This scenario can also occur if a patch lead is inadvertently looped back onto the same Switch/Router. Resolution Disconnect the Ethernet cable from the controller and it will start up correctly. On a very busy network or under a broadcast storm condition the controller will protect itself as detailed in Controllers go offline during a broadcast storm.

Issue SmartStruxure Lite provides Script library and Firmware upgrades through a password protected website. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite (SSL) Cause Requesting further documentation, firmware, and login credentials to the SmartStruxure Lite website (SmartStruxure Lite Solutions) Resolution SmartStruxure Lite can be purchased over the counter by anyone. To get access to the SmartStruxure Lite website for downloading firmware,scripts, and further documentation, site engineers will need to go through the training program. Until this is completed, they will need to seek support from a trained SE partner or branch for support.

Issue Errors in Vista Workstation alarm window: "Failed to execute report XXXXX-YYYY, Error in "DDE Execute" command[27]" "Warning logged in B0WARLOG.TXT on node XXXXXX" Contents of B0WARLOG.TXT: "Could not open report XXXXX-YYYY, hRes=[-2147467261]Invalid pointer" Product Line TAC Vista Environment Vista Server Microsoft Windows 7 Microsoft Windows Server 2008 Cause Vista Server does not support running as a service under the local system or interactive user account. A PC account that has local administrator rights must be used to run Vista Server. Resolution Follow the registration instructions for Vista Server in Registering/Unregistering TAC Vista Server as a Windows service when registering TACOS.exe as a service.

Issue What is the best way to update Modbus RTU points through the X Driver? Product Line Andover Continuum Environment Continuum Modbus RTU XDriver Cause Requesting values directly will cause additional polling to occur and may conflict with the Plain English polling program. Resolution Polling of the X Driver points should be performed by a single Plain English program (or sequenced programs) that ensure only 2 requests are made per second (See Typical data throughput rates for Modbus XDrivers). Whenever programs, graphics, alarms, list views etc are going to be used to read the X Driver values then annex points should be used. An Annex point is a numeric point (not an X Driver point) that will get automatically updated by the X Driver if its name is put into Parameter 6 of the X Driver point. Annex points are required for block reads, but even if you are doing an individual value read, this is the most efficient way of mapping the X Driver point value into another point that can be used by the rest of the system. Another advantage of using annex points is that if an invalid or bad value is received by the X Driver, it does not update the Annex point even though sometimes the X Driver point itself can go to a NotSet or a 0 value until the next valid read is received. The annex point always holds the last known good value. Also see Using Modbus RTU X Driver to connect to PM700 and PM750 Power meters for an example application for polling Schneider Electric power meters.

Issue What is the correct cable to use to communicate with the NPR 2000 via its serial port? Product Line TAC INET Environment I/NET Site Cause The getting Started book incorrectly specifies that you may connect the com port of the computer to the com port of the NPR 2000 using a standard serial cable. Resolution The correct cables are the same cables used to connect to a 77xx01 emutap, the CBL072. Cable Connectivity to I/NET has more information on this cable.

Issue Satchwell "AMS" and "AMSH" series Spring Return Rotary Actuator requires replacement by S-E M700 Spring Return Linear Actuator due to obsolescence. Product Line Field Devices Environment Satchwell "AMS" series Spring Return Rotary Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body. Satchwell "AMSH" series Spring Return Rotary Actuator installed on Satchwell MZF or VZF series 125mm and 150mm Plug and Seat Valve Body. N.B. Where a Satchwell "AMS" series Spring Return Rotary Actuator is installed on a Satchwell VV Butterfly Valve Body then NO simple Actuator replacement is available. See Replacement of Satchwell V V series Butterfly Valve Body Cause Obsolescence of Satchwell AMS and AMSH series Spring Return Rotary Actuator. Resolution The new actuator is 24Vac and the control signal will need to be converted from 230Vac to 24Vac, this could be achieved by a transformer and 2 off 230Vac relays. The old signals switch the coils of the relays. The relay contacts switch 24Vac to the new actuator. Replace Satchwell AMS or AMSH series Spring Return Rotary Actuator with S-E M700 Spring Return Linear Actuator and Linkage Kit: AMS = M700 + L7SV (880-0126-000) Linkage Kit. N.B. M700 is available with two different spring return actions M700 - SRSU (880-0430-000) = Spring Return Spring Up ( M700 - SRSU will CLOSE a Satchwell Valve.) M700 - SRSD (880-0440-000) = Spring Return Spring Down ( M700 - SRSD will OPEN a Satchwell Valve.) Should the Satchwell AMS series Actuator include a wired Auxiliary Switch then the following S-E M700 Actuator specifications which include 2 independent 24 volt 4 amp AC-1 rated SPDT Auxiliary End Point Switches should be considered as appropriate: M700 - S2 - SRSU (880-0431-000) M700 - S2 - SRSD (880-0441-000) Alternatively Auxiliary Switch Pack S2 (880-0104-000) - Two independent 24 volt 4 amp AC-1 rated SPDT Auxiliary End Point Switches may be purchased separately permitting local installation. Particular care should be taken when selecting a TAC Forta M700 Spring Return Actuator to replace an existing Satchwell AMS Spring Return Actuator. Please refer to Replacement of Satchwell "AL..S" series Spring Return Linear Actuator. Please check the latest catalog for current equipment.
