I was practicing some concepts on concurrency in periodic tasks where I handle such using SSV instruction to inhibit tasks, as suggested by Logix5000 Programmer Manual and after I downloaded the program through ethernet cable to the PLC (Compact Logix L32E) it became impossible to communicate to it, showing 1789 Virtual Chassis in the Who Active Window isntead of the PLC I'm using. I tried to reconfigure it using RSLinx and serial cable but I had no success, the only solution was reset it by removing its batery.
I was wondering what could have caused the problem.
