Concerns products with the Order Nos.:
6ES5 377-0BB41 RAM submodule with battery backup
6ES5 355-3UA11 355 memory module for S5-155U
6ES5 155-3UA11 S5-155U central controller
6ES5 155-3UA21 S5-155U central controller
The 377-0BB41 RAM submodule with backup can be used in the
355 memory module. However, the backup function is not available
because after plugging in of the RAM submodule, the latter will
be erased upon startup (same response as RAM without backup).
