  1. Greetings! I have several Access Names defined, which have Primary and Secondary data sources configured, and Failover is enabled.  We are using the built-in failover logic to determine when failover should occur (we are not manually forcing failover). I would like to show some sort of indicator to the user when the Secondary source is being used.  I am aware of the $Sys$Status tag which is true if the data source is connected and false if it is disconnected.  However, this tag doesn't tell us which source is being used (primary or secondary). Is there another $Sys tag or other tag that would tell us this info?   Thank you for any pointers!
  2. Lesson Learned - Wonderware InTouch SCADA

    Where would I find this option?  Thanks!
  3. [Hello, this is my first post - hope I posted in the right place.] We have multiple Logix5000 PLCs and are using Wonderware 9.x HMI. There are 4 SCADA PCs running Wonderware. Each is set up with DAServer and they pull the tags directly from the PLCs. On one SCADA PC, DAServer is continuously throwing the following error when attempting to read tags from a specific PLC: "Encountered following errors while establishing connection for New_PORT_CIP_000.HSPS.Backplane... ExtSTS=011A: Target Application cannot support any more connections". The tags from that PLC don't get updated on this particular SCADA PC. The "HSPS" PLC reports 7 active connections, with 64 available. CPU utilization is ~30%. The other PCs are not reporting this error and are working fine. I would be very grateful for any suggestions to track down this error. Thanks!
