Hello, You have 400F, 400H and 400 FH. The later one is the failsafe redundant variant. The hardware used is that of a 400H + failsafe perihery + specific function blocks and configuringto realize the failsafe functionnality. Extract of the 400H Manual: The S7–400H is a fault-tolerant automation system. You may only use it to control safetyrelated processes if you have programmed and configured it in accordance with the rules for F systems. You can find details in the following manual: SIMATIC Industrial Software S7 F/FH Systems http://support.automation.siemens.com/WW/view/en/2201072 |
