Hi good day to all,
I'm Andrei and came from the Philippines. I had a project which deals with an Auma Actuator and Omron PLC (Analog Input Devicenet). The Auma Actuator outputs the Motor position 0%(Close) to 100%(Open) through 4-20mA. I've had success the first time reading the Analog Signal.
After few Months, I was called and the case is that the reading went OFF. When I checked the current (I) reading through Digital Multimeter (DMM), I can see 4-20mA clearly. But when I try to look in the PLC program, it can't read 4-20mA. I've tried to use other 4-20mA sensor to check if the Analog Terminal is the problem but I encountered no problem at all.
In our application, we have used two (2) Auma Actuator. I have no problem with the other one.
What can I possibly do to make the PLC read the 4-20mA Analog Signal from the Actuator? I'm already out of options and blanked right now. Hope you can help me. Thank you very much Automation experts and I'll so much appreciate any help I can get.
