Issue After copying sections of logic from one application to another the pointers from that logic won't connect to other objects and therefore show up as red lines. Environment WorkPlace Tech Cause Copying sections of logic from an older application has been known to cause this. Resolution To recover the application remove all objects and reference tags that exhibit the connection issue, compile the application and then re-create the deleted logic by pulling objects from the Shapes window.

Issue What is the difference between the MNL-V3RV3 and the MNL-V3RV3-A? Environment  MNL-V3RV3 MNL-V3RV3-A Cause MNL-V3RV3-A is a new part number, and it isn't clear how it differs from the existing  MNL-V3RV3. Resolution The MNL-V3RV3-A meets the requirements of the Buy American Act (BAA).

Issue What are the expected voltages on the RS485 IO Module bus? Product Line Andover Continuum Environment Netcontroller IO Modules IOU Modules Cause Require typical values for troubleshooting first steps. Resolution Although the IO Module bus uses RS485 comms similar to Infinet or BACnet MSTP, the typical bus voltages when measured with a voltmeter are usually lower. Exact voltages will vary from system to system and depend on the amount of bus activity at the time, but the following will allow general troubleshooting: Typical DC voltage measured across the bus + to - = 0.7 to 0.8VDC but working systems may read as low as 0.4VDC Typical DC voltage measured Screen (shield) to + = 0.6 VDC Typical DC voltage measured Screen (shield) to - = 1.3VDC Note: If using Free Topology (FTT-10A) controller and modules, these use transformer bus coupling and will measure 0VDC across the bus.

Issue Alarm Manager configuration. Environment Alarm Manager Configuration Cause A different configuration of alarms is required on a Remote Sigma client. Resolution The Alarm Manager is shared by both the local and remote Sigma clients, therefore any changes in configuration effect both clients. If there is a requirement to send different alarms to the local and remote Sigma clients, then this is achieved using Routesets, which are allocated to the individual object alarms.

Issue The XIF parser could fail if there is a "-sign in a commented row in the XIF default field.

Issue Unable to update an ASC when adding a new MR to an existing system. Product Line TAC INET Environment All versions of I/Net utilizing HVAC applications. Cause On a system that has multiple sublan devices and adding a new or several devices to the controller, when updating the UPD files it appears to get downloaded but when the MCI update is done, only one point is written to the database. If the points are added manually, a Memory Error would come up indicating that there is not enough memory in the controller to do this. However, this is not seen when doing the UPD file update nor MCI Update. Resolution To resolve this issue, the following steps needs to be done: Connect to the controller Go to Edit/Controller/Configuration Verify that the controller does in fact have memory left If not, look at the trends that are on the resident I/O Points If possible, delete unwanted trends that are using up memory to free it up to allow these devices to be added Once done, go back to ASC Parameters and then update the ASC and MCI again.
