Hello pangkz, this looks like your module: 752-323/823; PROFIBUS DP 16DI/16DO - Wago However, from the picture it looks like you have a equal deviceto the left, you've already tried swapping the two modules (if they are equal)? Before disconnecting the I/O from the devices, if you want to try, then let us know. |

Hello pangkz, according to your pic, you use S7 300 with Wago I/O module 753-323. The WAGO module will set overload -LED on following conditions: • Short circuit of one or more outputs • Missing supply voltage to the output drivers • Fault of an output driver • Feedback When an output fault is detected, the electronic module transmits a periphery fault signal to the fieldbus controller board, thats why you get a system fault on your PLC. You should check thepossible errors above, especially missing supply voltage to output drivers, as you mentioned that you removed all connectors to field already and overload-LED stayed on. The I/O module switches the overload-LED off again once the fault has been corrected, and after a 1 second delay, cancels the periphery fault message. I have attached a link here to the manual of your WAGO module you will find all necessary information there. regards |
