Hello Kashir; You have a S7-200 PLC with a EM 277 Profibus slave module. And you would like to connect it to a redundant Profibus-DP master, namely a S7-400 H system. Siemens recommends a Y-Link as a solution in such a situation, where a redundant master system needs to connect to one or more single-port, non-refundant slave(s). It connects each Profibus master in the redundant H-system with the connected slave and maintains the master-slave link in case of switch-over of the S7-400H CPUs. Here is an article that describes the function and configuration if a Y-Link with a S7-200 slave: https://support.industry.siemens.com/cs/us/en/view/9952749 You will find details for the elements needed to build a Y-Link in the following document: https://support.industry.siemens.com/cs/us/en/view/6847578 Hope this helps, |
