The output is activated by selecting one or more VOUT_x signals, which are applied to LOUT_D4x.
Each safe digital output can be configured as follows (P03.30 for DOUT40):
– permanently OFF (DOUT40A/B = 0 V),
– permanently ON (DOUT40A/B = 24 V),
– equivalent switching,
– antivalent switching.
The test pulse length can be parameterised (P03.31 for DOUT40).
You can use the outputs to monitor passive sensors using test pulses. To do this, config­
ure one of the outputs to "Permanently on" and use the outputs DOUT4x A/B to supply
the switching device è Section 3.3, Sample circuits.
The following tables show the allocation of the logic signal LOUT_D4x to the output level for outputs
switching equivalently and antivalently:
