Hello faming,
Failed?! Do you mean internally? like losing the optocoupler?! Unfortunately you can't have it. The only S7-300 digital input module that supports diagnostics is the 7BH01 module. However, the channel diagnostics that you can get from this module are: 1- Wire break (ashunt resistormust be connected to transducer contacts). 2- Missing supply voltage. The other diagnostics refer to the module itself not to channels (Check attachment). Best regards. H-H Attachment7BH01.pdf (129 Downloads) |
