HaModCtu (FB)

FUNCTION_BLOCK HaModCtu

Function block HaModCtu is a standard up counter with automatic data synchronization in a high availability system Only internal variables and outputs are synchronized. Input variables and parameters are not synchronized. If needed, use HaModDataSync to achieve the same.

Note

It is not recommended to call utility blocks inside other function blocks in user application, this can impact the data synchronization between PLCs. For example, if HaModTon function block is used inside user’s function block, it will lead to data sync mismatch.
