Typical Application
A counter module is plugged into slot 2 (module address 2.0). A value of 100
is set on channel 0 of this module via the three–digit thumbwheel switches.
The incoming pulses are counted once the counter has been enabled by the
control program. As soon as 100 pulses have been counted, a signal (output
4.0) is released.
