2.12.8 PA_ENABLE
Enable process output data.
Each bit of this parameter is associated with a byte of the process output data channel.
Meaning:
Bit = 0 the corresponding process data value is disabled
Bit = 1 the corresponding process data value is enabled
If an object takes up several bytes on the PA data channel, the logic state of the bit which is associated with the first byte of this
object is the one used, and the other associated bits are not relevant.
