Hi all,
yesterday I finally menaged to run log file and I found out what the problem was. On my external control panel I have a push button to release tool from spindle. This input goes to pokeys and in PMC I have a ladder code to control the valve output (ESS port3pin3 ). When the button input was not active, the PMC code was deactivating port3pin3 many times per second.
In log file the output for dust hood was activated correctly (port3pin2), but when the output was deactivated there was no event in log file for deactivating output port3pin2.
So my guess is that when the output 3 was deactivated so many times it also at one point deactivated output 2.
I've corrected the code and for now everything works as it should. Attached is the picture of PMC code that didn' worked in my case.
Thanks everyone for helping me specialy Andy to remind me to run log file
Regards,
Peter
