Hello, We need some info like error codes, diagnostic dat, ....to find out where the error may be located. Start may be with the following: - is the Modbus driver dongleinserted in the CP341? - is the driver loaded in the CP? - is the SF LED on or off - do you see any error in online mode in the HW Config? - do you see error codes at the outputs of the FBs? - are you sure about the cabling on the interface? See chapter 7 of this manual http://support.automation.siemens.com/WW/view/en/25362836 |
