The professional counter module has 2 inputs for standard sensors.
The module counts the impulses up- and downwards with the two channels (BWU1574) or twice two channels (BWU1710) and outputs the result as 16 bit value (-32768 … 32767) via AS-i. The start value is -32768.
With the help of parameters the module can be set to zero as well as the counting direction can be defined. Different pre-divisors are available, which can be select via AS-i parameters as well.
As long as the AS-i parameter for setting zero is set the counting is stopped. After the setting to zero of the counting value a pre-divisor or the AS-i parameter for no pre-divisor must be adjusted again.
The module reports a peripheral fault at counter overflow (underflow).
