Integrated Functions

4; High-speed counters (30 kHz each), 32 bits (incl. sign), can be used as up/down counters or for connecting 2 incremental encoders with 2 pulse trains offset by 90° (max. 20 kHz (A/B counters)); parameterizable enable and reset input; interrupt facilities(incl. call of subroutine with any content) when the setpoint is reached; reversal in counting direction, etc.
