Issue Can the I/A Series R2 ModbusAsync driver be configured to control minimum send time between Modbus messages to the bus? Environment I/A Series R2, Modbus Cause The Modbus device under control is unable to process messages at normal rates and requires a delay between messages received. Resolution The minimum send time between Modbus messages can be controlled by adding a parameter into the drivers.properties file. Note: Requires modbusAsync-2.302.514.v1 or higher. Open the UNC with the admin tool and go to the Installation tab. Edit the drivers.properties file. Add the property (shown below) on its own line within the file. Set the value the number of mSec of delay between messages. Save the file and reboot the station (remember to backup the station when requested). modbusAsync.minSendInterval=1000

Issue Attempting to enter a conversion that references an object (point, PE function etc) results in error.. "Could not validate conversion formula" Environment Automation Server BACnet interface b3 device. Cause By design in SBO a point conversion can not contain references to other objects in the server. Resolution Remove the reference and substitute a hard coded value EXAMPLE: sqrt(elecvalue) * kfactor In the conversion above, 'kfactor' is an analog value in the b3, the conversion can't be validated due to the reference to kfactor. The solution is to replace 'kfactor' with its actual value sqrt(elecvalue) * 10

Issue Bindings do not work. Environment Binding BACnet Output Digital Output Cause When the BACnet point changes in value, it does not change the value of the Digital output.   Resolution The StruxureWare Building Operation core architecture (as of version 1.3) allows cross server “read” references, but not cross server “write” references. This was the design from 1.0, and effects everyone – not just BACnet (ie. script programs would have the same behavior). What this means for the BACnet associated value is that inputs (which are “read” references) can be done cross server, while outputs (which are “write” references) can be only be within a single server.

Issue Camera will not move to preset PTZ on video alarm, from Video Monitor the camera can be moved to the preset in live video. Environment CyberStation Video Server Video Monitor Cause Issue with accVideoRecordingSrvc.exe at workstation that is logging the alarm. NOTE: The accVideoRecordingSrvc.exe problem could happen at any workstation not necessarily the workstation receiving the alarm. Resolution Check all workstations looking for any indication that there has been a problem with accVideoRecordingSvr.exe Shutdown then re-start Continuum on the workstation reporting issues with accVideoRecordingSvr.exe

Issue When receiving an alarm from a BACnet device, the alarm text display does not match the text entered in the SmartStruxure configuration of the alarm object. Also performing a 'Recheck' from the alarm viewer results in the alarm text fields going blank. Environment AS ES BACnet device Cause As of version 1.3 SmartStruxure uses BACnet protocol version 6, as a result of that SmartStruxure is not able to read or write the alarm text message from BACnet devices. If a device includes the text message with an alarm event SmartStruxure will use the message when displaying the alarm in the alarm viewer but on alarm re-check it will use the alarm messages in the SmartStruxure database as it’s not able to read that information from the device. When using messages from the device and performing an alarm ‘Recheck’ the alarm messages will be blank unless they are set on the SmartStruxure side. This issue will addressed by SmartStruxure In the future when BACnet protocol revision 13 is supported. Resolution To work around this issue do one of the following: Configure the BACnet device so that no text is sent with the alarm. or   Enter alarm text on the SmartStruxure side to match the text sent from the controller.

Issue Can an automation server be installed with a backup database without the need for Workstation?  For example, can a backup database be installed on a USB stick that is programmed to 'auto-run' when it is plugged into the automation server? Environment StruxureWare for Building Operations (all versions) Cause Customer works in the industrial refrigeration industry and his field personnel are primarily mechanics with limited pc knowledge.  Wants to use a stand-alone AS to control the refrigeration system.  Sites are mostly remote (several hours by car and/or flights).  Wants to send programming changes, due to site installation changes, as a self-extracting and self-installing file on a USB stick. Trying to avoid supplying the necessary laptops and Workstation training to the mechanics. Resolution This feature is not available.  Workstation is required for database administration.

Issue After the "Windows is shutting down" message, the Windows displays a non specific memory error as shown below: lmadmin.exe - Application Error The instruction at "0x00000000" referenced memory at "0x000000". The memory could not be read.   Environment SmartStruxure Windows XP SP3 Cause Flexera Software (Licensing software used within Building Operation) does not support Windows XP.  This is a known issue which will not be corrected. Resolution There is currently no known operational issues with this error and only occurs when shutting down the Windows XP machine.  Upgrading the Operating System will remove this error.

Issue Linkage kits to be used with Satchwell ALE (s) , ALi, ALX (s), ALM (s) on Schneider Electric Venta V and VG Valve bodies Environment Linkage Kits Cause Linkage kits to be used with Satchwell ALE (s) , ALi, ALX (s), ALM (s) on Schneider Electric Venta V and VG Valve bodies. Resolution Use the L8TV linkage kit part no. 914-1080-000 on V type valve bodies e.g. V211, V211T, V311, V311T, V231, V241, V212, V222, V232, V292, V341 Use the L9TVG linkage kit part no. 914-108-000 on VG type valve bodies e.g. VGS211F, VG221F, VG311F

Issue What happens to Sigma globals if the network fails? Environment Globals Communications Networks Cause Site is to have a planned network shutdown, how will the Sigma controllers react to this? Resolution The Sigma controller using the global update, will continue to operate normally, but will use the last value received, so any changes will not be responded to. If the Sigma controller controls critical plant then the loss of global communications should be taken into account when programming.

Issue I/A Series G3 Software Drivers Returns Environment I/A Series G3 software drivers Examples: ENC-DRV-MOD, ENC-DRV-MOD-T etc.  Cause The wrong software driver was purchased for an ENC-520 and the ENC-520 has been shipped to the customer.  Resolution There are no returns on software drivers. A purchase would have to be made for the software driver that is required.  The existing driver that was wrongly purchased can be re-license for use on another G3 device by purchasing an I/A Series license change (IA-LIC-CHG). 

Issue Fan is activating though it is not commanded. Environment Zbuilder Xenta 121FC Xenta 121HP Cause Fan Conditioning is Active. Conditioning can be used to "stir" the air periodically, evening the temperature when the system is not commanded or forced off. Resolution Active fan Conditioning is determined by settings for Inactive time and Active time. (UCPTappOptions bit 8, Active=1) Inactive time - Maximum interval in minutes before the fan is activated, if not used during. Standstill time between Conditioning.(UCPTFanCondOffTime) Active time - Time in minutes that the fan runs at minimum speed during Conditioning.(UCPTFanCondOnTime) If the Fan Conditioning is active, the fan state will be monitored for activity during the specified Inactive time and turned on when Inactive time has passed. The fan will stay on for the specified Active time until reached then turn off, which begins the Inactive time monitoring again. If the fan is called for during the Inactive time before reaching the Inactive time, the Inactive time is started over when the fan is released.
