Hello SaifKabi; Setting a second CPU as a Selectable Master on a Profibus network is not easily done, in my experience. The only way I could suggest you do this would be to setup a Software redundancy configuration between the 2 CPUs. That way, you could command the failover of the main CPU to the reserve CPU and let it control the Profibus nodes on the redundant ET 00M stations attached to the CPUs. Have a look at the following links, to help you determine if this is an acceptable solution for your project: Software redundancy for S7-300 and S7-400: https://support.industry.siemens.com/cs/ww/en/view/1137637 FAQ collection for Siemens Software Redundancy https://support.industry.siemens.com/cs/ww/en/view/87604432 Hope this helps, Daniel Chartier |
