HaModAIO (FB)

FUNCTION_BLOCK HaModAIO

This Block can add in a standardized way scaling, limiting, alarming and other functions as often available in DCS type environment for analog inputs and outputs.

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.
