Configuring digital outputs
The parameters between I26 and I33 configure the function associated with the digital outputs.
Both analogue and triac outputs can be configured as digital outputs if disabled as analogue outputs as previously explained.
As with the digital inputs, the parameters configuring the function assigned to each digital output consist of an absolute value indicating
the function and a sign showing its polarity:
Negative = Normally closed (NC)
Positive = Normally open (NO)
The value 0 indicates that no function is associated with the digital output.
