IO_INP_CTRL 1-2
The Polarity flag determines whether the input is low active (0) or high active (1). The input
mode can be seen in the following table. The PinState flag is used to query the current status of
the input.
For inputs, the PinState bit refers to the inverted output side of the optical coupler. This means
that an open input sets the PinState bit to “1”.

Trigger
If more than one input is being operated in trigger mode, these inputs are logically linked by
AND.
