I am working on Ignition Edge, PLC = CJ2M-CPU35, using Omron FINS/TCP driver.
Tag connections are fine, able to read and write.
However sometimes when gateway and plc are powered off and powered back, all the tag status would become uncertain, with the circle ? icon, even though device connection status is Connected.
Have tried to enable/disable the connection, on/off the plc, the tag status still remains as Uncertain.
The only way is to restart the gateway(ie restarting the pc).
Tried searching through the logs, but could only identify FinsWriteRequest warning:
java.util.concurrent.TimeoutException: timed out after 2000ms at com.inductiveautomation.omron.fins.client.tcp.FinsTcpClient$sendCommand$timeout$1.run(FinsTcpClient.kt:103) at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:672) at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:747) at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:472) at java.base/java.lang.Thread.run(Unknown Source)
Could someone advise how should i go about troubleshooting the problem?
Many thanks in advance!
