UNICO2 Posted July 24, 2017 Report Share Posted July 24, 2017 Hi - I have been unable to recreate this problem however, one of our engineers said that when the sensor input goes over 20mA, the UIA-0800N value drops to less than 4mA in the Unilogic program/HMI display. Maybe like a protective mode or it knocks the entire rail offline - not sure. I measured the actual input as 21.62mA from the sensor on my PLC setup. The other engineer is using a different PLC setup with slightly different power and grounding. Specifically he is grounding the power supply COM to GND. Any ideas? Thanks!
