Hello, First of every thing you should check that your CPU or Module is compatible with software redundancy. Which modules can you use when implementing software redundancy? For your case "6ES7314-6EH04-0AB0" the mentioned CPU doesn't support SW redundnancy. Then please read the following manual: SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7. To access the On-board IOs for other Compact CPUs which supports SW redundncy, please note that each CPU may have redundnant program + non-redundant program. On board IOs and/or centeral IOs for each CPU rack should be accessed for every CPU in the non redundnat porstion of the software. And it can not be accessed by the other CPU. Hope this helps. |
