Features

The counting function is performed within the bus module and accordingly the expansion module. It works independently of the user program and is therefore able to response quickly to external signals. A simultaneous counting operation of several expansion modules is possible.

Each module counter can be configured for one mode out of 10 possible ones. The desired operating mode is selected in the PLC configuration using module parameters. After that, it is activated during the initialization phase (power-on, cold start, warm start).

The data exchange to and from the user program is performed using input and output operands. While integrating a module containing a Fast Counter in the PLC configuration, the necessary operands are created and reserved immediately. Thus a counter implementation carried out later on does not cause an address shift.
