The Function Block ONB_IO_CNT is used to control the fast counters which are integrated in AC500 CPUs PM55x and PM56x.
The operating modes of the Fast Counters are described in detail in a separate chapter: Fast Counter
To activate the fast counters of AC500 CPUs PM55x and PM56x, the parameter “Fast Counter” of the I/O device must be set to the desired counting mode in the control system configuration.
The Function Block ONB_IO_CNT has an integrated visualization block that can be used to control all block functions in parallel to the user program (if input EN_VISU = TRUE). A detailed functional description of the visualization and how to integrate it can be found at the end of this Function Block description.
