Hi All,
I am using S7-300 CPU-317-2DP with IM 153-2 for Software Redundancy. I am using Ethernet as Redundant Link.
When the Master PLC is active, in FC100 we transfer redundant DB_NO = required DB NO and DB_NO_LEN = Required Length. This will transfer Data to Reserve PLC.
My question is how much length I can Specify to transfer the DBs?
Also when Master to Reserve Changeover takes place (PLC A --> PLC B Transfer),then PLC B now master takes few Seconds to takeover till then SF LED glows.
Is there any way to reduce this changeover time?
Thanks in advance for all your suggestions.
Best Regards,
PH
