Hi guys, I have a problem with an im151 standard, hope you can help me. first of all, my hw config is correct, (online checked, all modules are green). the problem is that, having 24vdc on an module input(the green led is on), I cannot see it on the plc. the same problem with the outputs. I can force a bit to TRUE from the program but the DO module is unaffected. (the output leds from the module are off). i've tried replacing the im module with a good one but I get the same problem. what can be the reason for all of this? thank you in advance. ------------------------------------------------------------------------------------------ |
