AC500 IO Channel Error
I have the following problem, after doing some tests with equipment in the field, I started to connect with the PLC (PM573) and then to do several tests remotely without success. I decided to connect locally, when I saw the cards had turned on red the led CH-ERR in all.
Someone can help me, I have restarted to factory the driver and downloaded the program again, but the problem persists.
Attached two images, one is what I see from the Control Builder on the DI524 card and the other a photograph of the DI524 showing the active 1.0 / 1.7 channels.
As Titus correctly wrote, make sure that the connection to the power supply of every module is right, in addition to this i suggest you to link and test one module at a time, inserting it first as HW - pay attention to the UP / ZP wire and then enable in the SW Control Builder / your program.
Hope this help you
