Hello tauraus; You cannot use S70300 modules directly on a S7-400 rack, they are not physically compatible. For example, the sizes are different between the S7-400 and S7-300 I/O modules, and the S7-400 uses an active backplane that the S7-300 I/O modules cannot connect to. However, you can easily "integrate" S7-300 I/O modules as Profibus-DP or Profinet slaves to the S7-400 CPUs, as part of a ET 200M system, with a IM 153-2 or IM-153-4 interface module,. Look at the attached picture, taken form the following manual: SIMATIC Distributed I/O device ET 200M Study the document and come back to us if you have more questions. Hope this helps, Daniel Chartier |
