Max redundancy memory AC800FR
Every redundant task has max redundancy memory setting in bytes. Also AC800FR in HW structure has max redundancy memory required setting in bytes. Does it mean that sum of max redundancy memory of all redundant tasks have to be identical to max redundancy memory required?

I don’t think so because I have some project configurations from running plants where summation of max red mem of all task is not identical with value @ hw structure in boot parameter. It is different.
And these values are calculated internally while compilation (during plausibility check) also can’t be edited.

As specified above, the max redundancy memory is calculated during plausiblity check, the user should ensure that suffucient memory is assigned in 'Configured redundancy Memory' in Boot Parameter tab of AC800FR parameters window in HW structure. This should be greater than calculated Required Redundancy memory.
