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.

Issue Where can I find Plain English Drivers and documentation for them. Environment Plain English Drivers Cause Schneider Electric Product Support Services does not supply Plain English Xdrivers, nor are they supported. Resolution Schneider Electric does not provide support for Plain English Drivers and no longer provides support for them There are, however, two xdriver manuals available on The Exchange Download Center. Carrier CCN Dataport Manual (32MP, 30GN, 30GB, 30HX, 30GT, 23XL, 19XR, 19EF) Mammoth DDC Manual

Issue HID iClass SmartCards can be ordered with 2K, 16K and 32K memory. Which memory amount is required when using BioScrypt iClass readers with the Continuum - BioScrypt integration software?   Environment CyberStation, BioScript IClass Smart Cards. Cause A project requires HID iClass SmartCards, BioScrypt iClass readers and the Continuum - BioScrypt integration software. HID 2K iClass SmartCards do not have enough on-board memory to store fingerprint templates.   Resolution If you are configuring the BioScrypt iClass readers for the standard 1:1 TEM fingerprint format, you need 16K memory HID iClass SmartCards. If you are configuring the BioScrypt iClass readers for high resolution 1:1 BUR fingerprint format, you need 32K memory HID iClass SmartCards.  

Issue When integrate with Pelco Endura system, after configure video serer in continuum correctly, there is only one camera can be found, the other cameras not come in. Environment Continuum 1.92~1.94 Endura 2.0 Cause The cameras in Endura not be assigned a sequence number. Resolution Ask Endura engineer to set a unique number to each camera Click "learn Camera" in Continuum video server editor After the above steps done, all the cameras will come in Continuum if the connection in Endura side is correct.

Issue When Continuum integrates with a Pelco Endura system, although the connection is correct, no camera comes in to Continuum. Environment Continuum 1.92~1.94 Endura 2.0   Cause The camera default name assigned by Endura is too long in length. HP software installed on the machine (such as HP protect tools) Resolution Ask the Endura engineer to modify the camera's name and assign a unique number for each one Uninstall the HP software from the machine Click "Learn Camera" in Continuum Video Server editor. If the problem still exists, rebuild the machine and do a fresh installation. Then try again

Issue Is it possible to use dynamic SNVTs in StruxureWare Building Operation? Environment StruxureWare Building Operation version 1.3. Cause A XIF file including Dynamic SNVTS is often created by a LNS plugin and depending on the settings in the LNS plugin the XIF file changes. Even when the Xif file changes the program ID in the XIF does not. And in SmartStruxure it is not possible to import two XIF files with the same program ID. Resolution Dynamic SNVT works but only for one device, if different devices have different settings in the LNS plugin only one can be imported.
