Issue MTA-File update Error, code = 4038 PVR block values changed from TAC Vista not saved in MTA file Environment TAC Vista TAC Menta TAC Xenta 401, TAC Xenta 301, TAC Xenta 302, TAC Xenta 281, TAC Xenta 282, TAC Xenta 283 Cause This could be because the changes made leads to a division by 0. Resolution Open the MTA file and check if the changed value can cause a division by 0.

Issue Need a way to automatically acknowledge alarms. Environment CyberStation Cause All alarms need to be logged in the Continuum database but there are certain alarms routed to another system for processing. It is preferred that these are automatically acknowledged in Continuum so as not to tie up the Continuum logged on user. Resolution Continuum can do this using the Plain English AckAlarm function. Scripts within a Pinpoint graphic can also be set up to do this. Refer to the Continuum online help system and search for 'Alarm' in the index. Select 'Alarm functions, Plain English' and review the four subtopics: AckAlarm, Overview, Pop Alarm and User-defined alarm functions.

Issue Receive "Error 1606. Could not access network location\." when installing I/NET Seven Software with StruxureWare Building Operation Environment I/NET Seven SmartStruxure Solution 1.3 Cause When uninstalling / Installing I/NET with Building Operation software already installed the Enterprise Server and InetIoSrv service must be stopped.  In some situations when not installing the for site it may be best to set both the Enterprise Server and InetIoSrv services to manual avoiding this situation. Resolution To resolve this problem.  Stop the Building Operation Enterprise Server service, either from the Software Administrator application or from the Windows Services. It is also recommended to stop or remove the InetIoSrv service prior to any update of the I/NET Seven software.

Environment TreeTech 3.1 Cause Using TreeTech to do GCM backups with the demise of ProBlock Resolution On page 25 of the TreeTech Engineering Guide (F-26640), the recommended setting for ODSR (output date set ready) is ON for a GCM-86000. At times, the age and model of laptop may require that ODSR be set to OFF.  Try it.

Issue Unable to see dynamic values in TGML graphic on workstation remote. The graphics work fine on the local Vista server/workstation. Environment TAC Vista 5.1.X Workstation remote Cause A version mismatch between the Vista server and the workstation remote. Resolution Install the correct version of workstation remote on the remote PC

Issue Not all changes in a Notes file are saved. If opening and edit a Notes file, save and then continue writing only the changes before the save will be changed. Environment Vista 5.1.x Cause The Notes file will only be saved once then you need to close it and open it again. Resolution When editing a Notes file only save once then close the file. If you need to write some more close the file and open it again.

Issue How to calculate the pressure drop across a fully open valve Environment Valves Cause End user wants to calculate the pressure drop across a  valve for a given flow rate. Resolution 1. Select a valve to suit the application and note its Kvs. note if the figure is Cvs then Cvs * 1.03 = Kvs 2. Flow rate is required. P (bar) = (m3/hr / Kvs) squared. or P (bar) = ( (l/s * 3600 /1000) / Kvs) squared. To convert to Bar to Kpa:  1 Bar = 100 Kpa

Issue What is the difference between the TTS-SD-LCD and the TTS-SD-LCD-4 smart sensors? Environment Field device sensors Cause Documentation Resolution The difference is in the number of buttons, the TTS-SD-LCD has six buttons while the TTS-SD-LCD-4 has only four.

Issue Occasionally get a alarm in Vista that is connected to the bit 16 of the error block in Menta (Mainloop overrun. The application program can not execute within the specified cycle time) Environment Vista Menta Xenta Cause In Menta under Program Specification there is a parameter called cycle time. This parameter tells how often the program should be run in the Xenta. If the program take more time to execute then the specified value Vista will show a error connected to a error block in Menta, "Mainloop overrun. The application program can not execute within the specified cycle time" Vista will not show this specific text, Vista will show the text that you choose to show in the Alarm block connected to the Error block. I.e. In Menta you have a error block that leads to a XPR block (expression block) that have the expression A&16, when this expression is meet it goes to the alarm block that will generate an alarm text of your choice. (16 is the bit that tells a Mainloop overrun. The application program can not execute within the specified cycle time have occurred.) The Error block has several condition and work like this The output of this block is an integer value where each bit represents an internal signal or error from the system program. Each output bit is set as long as the error condition remains, remains. In the case of a restart after a power failure, the output bit is set during the first program cycle after the restart. The output value is zero when no error conditions are set. Conditions:   Bit no. Output value Description 0 1 Restart after power failure 1 2 Integer underflow/overflow 2 4 CNT block overflow 3 8 RT block overflow 4 16 Mainloop overrun. The application program can not execute within the specified cycle time 5 32 At least one of the switches on one of the I/O modules associated with the application, is in the position for manual override (ON, OFF, MAN) of the output 6 64 Indicates that an OP is connected, and the user is logged in at medium (yellow) or high level (red). 7 128   8 256 Dial-up modem line to TAC Xenta unit disabled 9 512 Update of a Network variable value was not received within the set Period 10 1024 There are tripped priority 1 alarms in the alarm list 11 2048 One or several I/O modules offline 12 4096 I/O in forced mode 13 8192 There are tripped and unacknowledged alarms in the alarm list 14 16384 There are tripped and not reset alarms in the alarm list Resolution To remedy this error change the cycle time to a higher value or make the Menta code lighter

Issue The Sigma object associated with the first entry in the Gateway.txt file of an S-IC3-SNP integration controller when displayed in the Sigma System Manager, always shows its default value. Environment Sigma S-IC3-SNP Cause There is an issue with the way that the S-IC3-SNP processes the object mapping file (gateway.txt) file, please note that this issue does not affect the earlier S-IC-SNP Resolution TPA-LOND-08-0011.00 provides a workaround for this issue, the work around involves adding a dummy line to the Gateway.txt file, this then allows the first object to be displayed normally.

Issue Every time the trendlog data should be viewed an alarm saying" The digital signature does not match, values might not be reliable". How can we avoid this? Environment Vista 4.4.2 Cause In old Vista versions like Vista 4.4.x we had something called Digital signature to check that the data in the SQL database had not been tampered with. This have been taken away in later Vista version as it slowed down and caused problems with trendlogs. The alarm indicates that someone have done something in the SQL database and the digital signature does not match.   Resolution It is possible to turn off the Digital signature in the Vista server setup under the SQL tab and then restart the Vista server. Then Vista will not do this check and the alarm should not appear.

Issue Can a BACnet device instance number be changed from the UNC or ENC? Environment I/A Series, Niagara R2 and G3 Cause Some third party BACnet devices come with a fixed instance number based on their model and address on an MSTP trunk.  Having them on multiple trunks will cause duplicate instance numbers in the system.  Resolution The R2 software does not have capability to do this.  If the device instance number is changed in the shadow object communications to the device is lost before the new instance number is written to the device.  The G3 software has a button at the bottom of the BACnet Device Manager page called "DeviceID" specifically for this purpose.

Issue What is the history capacity for the Jace-6 and Jace-7? Environment Niagara G3, Jace6, Jace-7 Cause Technical product information update. Resolution It is recommended to limit the histories in a Jace-6 or Jace-7 to 1600 histories or less.

Issue The MNB-1000-15 status light is solid red.   Environment WorplaceTech, MNB-1000, MNB-1000-15 Cause The MNB-100-15 (Remote IO) was not added in the MNB-1000's application. Resolution The Remote I/O module must be configured in the MNB-1000’s application. Also at least one of its inputs (R1U10x) or outputs (R1UO0x), must be connected to an input or output in the MNB-1000’s application. If a MNB-1000-15 input/output object is placed in the MNB-1000 application unconnected, it will not be recognized by the MNB-1000 and the MNB-1000-15 status led will be solid red.  

Issue Database schema upgrade failed Environment Vista 5.1.X taclogdata database SQL 2005/2008 Cause The error message in the b0warlog suggests this is caused by the automatic database schema upgrade failing. Resolution See TAC Vista installation manual section 5.3

Issue Are there replacement part numbers for the MNL-V1RV3 and MNL-V2RV3 circuit board and base actuator assembly? Environment MNL-V1RV3 and MNL-V2RV3 Cause Replacement of circuit board and / or base actuator assembly required. Resolution MNL-V1RV3 circuit board assembly is MNL-V1RV3-500 MNL-V2RV3 circuit board assembly is MNL-V2RV3-500 Actuator base assembly is MN-FLO-701

Issue UI-8-10 module is reporting no change of state on inputs when shorted. Environment UI-8-10 Cause Setting the voltage range switch to 10V when the Reference Resistor is in the on position is an invalid configuration. Resolution Change the voltage range settings to 5v on the input.

Issue Continuum controller with the lowest ACC Net Id is the time master of the network and has correct time but it is not updating the other controllers as expected. Environment CyberStation All CX and bCX master controllers. Cause Time master controller does not know about one or more controllers on its Network. Resolution Perform a global teach to ensure the time master knows about ALL the controllers on the network, then do a backup to flash (if applicable ) to make sure if the controller re-starts it still has accurate information about its peers on the network.

Issue How different are these controllers and can they be swapped out in the field? Environment CX9400 CX9410 Cause There are differences between the 2 controllers and there are considerations when swapping them out Resolution The CX9400 has 4 MG of memory The CX9410 has 8 MG of memory.  The co-processors of the controllers are also different, so it was never possible to just add memory in the field, they had to be shipped to repair to add the memory and change the co-processor. The units can be swapped out, but considerations are related to memory. If the functions that are being used are more memory intensive then swapping from the 9400 to the 9410 could cause latency issues or other performance problems.
