7.5.3 Setting the DIP switches
Select static mode or pulse counter mode using the DIP switches on the front.
– In static mode, inputs DI1 ... DI8 are activated, 0 V ... 30.5 V DC voltage
– In pulse counter mode, pulse inputs DI1 and DI7 are activated, 0 Hz ... 100 Hz pulses

The pulse counter function is only available in PLC / Modbus/RTU mode and in dual
mode. Set the operating mode using the PSI-CONF software (from page 35).
