Hello Surez; If your idea is to continue using the S7-300 I/O modules with the S7-400 CPU, you cannot use the IM 360/IM 361 interface modules for S7-300 extended racks. You have an option to re-use the I/O modules: you can easily replace the S7-300 CPU with a IM 153-1 or IM 153-2, transforming the S7-300 rack and I/O modules into a single Profibus-DP slave that you can connect to the S7-400 integrated Profibus master port. See this documentation on the ET 200M: https://w3.siemens.com/mcms/distributed-io/en/ip20-systems/et200m/pages/default.aspx https://www.automation.siemens.com/salesmaterial-as/brochure/en/brochure_simatic-et200_en.pdf https://support.industry.siemens.com/cs/attachments/1142470/ET200_e.pdf Look at section 2.1.5 for an example of configuring the ET 200M Profibus slave for a S7 master. Hope this helps, Daniel Chartier |
