Hi amperautomation, Normally it is not possible to read a hardware output. The reason is very simple, the hardware does not provide this information. Even if outputs are monitored in TIA Portal, this can only be done for the values in the process image, it is not possible to monitor a peripheral output. Kind regards |

Download the sample application for PLC diagnostics for s7-1500 PLCs. There are many tips and tricks Siemens uses to implement a very robust method of displaying diagnostics information, which seems very similar to what you wish to do. Perhaps the sample library will work in some ways directly for you, and in other ways suggest design considerations which make the task easier. https://support.industry.siemens.com/cs/document/68011497 https://support.industry.siemens.com/cs/document/98210758 And perhaps something in this link will also be useful: https://support.industry.siemens.com/cs/mdm/109747174?c=95820762507&lc=en-AF Search this support site and see if you find something you really like.
