Can anyone help or is there a document for this? I am using WinCC through the TIA Portal V11 and the hardware is the TP900 Comfort. Thanks all, Dan

You need a RS 422-RS 232 converter (6AV6 671-8XE00-0AX0) and you must set the DIL-switches at the back of the panel. You can find all needed information at the TIA V11 manual at chapter 9.11 -> Modicon Modbus RTU http://support.automation.siemens.com/WW/view/en/53385672 best regards
