I have two CPU 414 -4 H one configured as Master and the second as slave . My trouble is when i switch off the master the slave takes over , but when i try to go online it says the connection to master is lost , but you can use the saved version for diagnosis . Why does this happen.Seconldy when i try to go online to the program ( when slave takes over ) none of the block could go online on the program structure the Blocks are difined in master PLC.It works fine when slave is on line but how can i go online to the CPU to check the blocks . When you have a redundant configuartion you have the entire program difined in Master ? How does the slave configuration actually work in the event you loose one .
