Hello maher; Take some time to consult the following manual: SIMATIC Fault-tolerant Systems S7-400H You will find all pertinent information on configuring and commissioning a S7-400H in its pages. For example: Specific blocks for S7–400H ● OB 70, I/O redundancy errors ● OB 72, CPU redundancy errors SFC 90 "H_CTRL" can be used to influence fault-tolerant systems as follows: ● you can disable interfacing in the master CPU. ● you can disable updating in the master CPU. ● you can remove, resume or immediately start a test component of the cyclic self-test. NOTICE Required OBs Always download these error OBs to the S7-400H CPU: OB 70, OB 72, OB 80, OB 82, OB 83, OB 85, OB 86, OB 87, OB 88, OB 121 and OB 122. If you do not download these OBs, the fault-tolerant system goes into STOP when an error occurs. Hope this helps, |

As I recall, absence OB70, OB72 does not cause a stop |
