Hi guys Hope everyone doing OK I am an electric technician for the food industry and I come across Yesterday to an Unifiller machine with Unitronics PLC and V200-18-E4XB. The output of the I/O card control few pneumatic solenoid. One particular solenoid is not working anymore. I check the power supply, the integrity of the wire and the status of the solenoid and all are working 100% The positive of the solenoid is wire direct on the OUT 13 of the V200-18-E4XB. When running the program on the PLC I can't see any voltage output from the channel 13. I ask the operator to create a new receipt in case the original one was bugged. I open the I/O card and I see that all the output are managed by mosfet, so very reliable! Is very had for me to believe the channel 13 is faulty..... Any suggestion, test, or.... YES buy a new board! 🙂 Much appreciate Fabio
