Hello chetan; It seems that multicomputing is not supported by S7-400H systems. As shown in the SIMATIC Fault-tolerant systems S7-400H manual: Restrictions of the fault-tolerant CPU compared to a standard CPU Function Restriction of the fault-tolerant CPU Hot restart A hot restart is not possible.OB 101 is not possible Multicomputing Multicomputing is not possible. OB 60 and SFC 35 are not supported Startup without configuration loaded Startup without loaded configuration is not possible. ... Could you give any indication on the load supported at this time by your S7-417H, and the additionnal load you plan to integrate? The S7-417H is a monster of a PLC and it takes quite a process to fill it up. In my experience, when we have faced such issues (it happened in an alunimium plant we programmed with PCS 7, all OB3x were at their limit) we had to setup another redundant controller pair to split the control area into sections that we distributed through multiple controllers. Hope this helps, Daniel Chartier |

Hello chetan; Unfortunately, the MLFB you have shown is the part number fpr a S7-417H bundle purchase. Could you please read-off the MLFB from the CPU directly, for example: 6ES7417-4HT14-0AB0 Open the link above to see technical information on that CPU model. Hope this helps, Daniel Chartier |
