I have observed that in the later versions of Ignition (7.7) , on expiry of trial period of 2 hours, the Ignition Gateway doesn’t respond to any external communication from OPC read/write or a TCP read/write thru our module. In fact our module hangs, i.e. it doesn’t come back to life after reset of Ignition’s trial period. We can’t even restart our module as on restart, Ignition will be waiting for some response from “localhost”! It gives some internal error after few mins! Our module then disappears from the installed module list and we can even reinstall our module as it again goes in wait mode from “localhost” and gives internal error page afetr some time!. We have to restart the GCU! In earlier versions of Ignition (7.6) our module used to continue to run even after expiry of the trial period of Ignition and communication with our models or OPC client used to run!
Has something changed in Ignition in later versions? How can we capture the trial period expiry event in our module and prevent such a dead lock situation!
What are your comments on this behavior.
