PLC "program error"
One of our petblowing full automatic machines just switched off the heater line during operation and I traced out that there was no signal from PLC, so I switched off the machine and latter switch-ON. When the machine was switched-ON, the interface board, though, have its 22vdc instead of 24vdc...- Yomtech
