Software: PAC Project R9.4007
PAC Control Professional: R9.4d
Build Date: Mar 31 2015
No communication with controller (no ip ping, no display runtime, no PAC Manager, no PAC Terminal), controller is blocked
After it doing manually turn off and manually turn on the controller has these errors:
-539 Info I/O error; performing retry.
-25 Error Port or object is not locked.
-534 Info Attempt(s) to communicate with I/O Unit failed.
And this code is repeated many times until the controller starts to work well:
-4 Info Device has powered up. (‘Powerup clear expected’ message
Currently the controller works properly.
But why could it happen? I’m confused, I do not understand why?
I appreciate your help.
