Hello,
I have a Micro850 PLC that has 5 2080-IF4 plug-in modules attached. Each of these modules are programmed to read 4-20 mA output signals from various sensors. It also has interlock switches connected to embedded digital input ports. When I download the program to the PLC from CCW, the message prompt that enables 'Remote Run' does not appear. I can't seem to switch the controller to run mode. Moreover, while connected, the I/O tags all read 0. I have tested the sensor wire leads with multimeter and they do give out output signals in the range of 4-20mA. Not sure why CCW is unable to read. The DI status LEDs also light up when I turn on the switches. I assumed that it might have to do something with the firmware, so I reset the firmware to default, that didn't help either. Any ideas on what the issue is or how to fix the issue? Thanks.
