Hello Pavel? Where did you get your information? If you are trying to setup yout CM 1241 as Modbus slave and you receive an error message stating that the RS 232 posrt is unavailable, please show us a screenshot, and check whether another function is tying it up. The CM 1241 can be used for Modbus slave application, but it is limited to a single slave (by RS 232 standards). See for example the introduction to this document, and the information provided earlier by Industrial Networks in his post.: https://support.industry.siemens.com/cs/ww/en/view/47756141 Hope this helps, |
