Description:
Using this parameter, it is possible to view the status of the product digital inputs, according to the plug-in
module connected. Refer to parameter P0027 in
The P0012 value is indicated in hexadecimal, where each bit of the number indicates the status of a digital input,
that is, if BIT is "0", DI1 is inactive; if BIT
0
of DIx active or inactive takes into account the signal type in the DIx defined by P0271.
The activation of DIx depends on the signal in the digital input and on P0271, as per

NOTE!
Parameter P0012 requires the user to know the conversion between binary and hexadecimal
numerical system.
