The ADI4 DP slave is operated with the specific message frame type: Four axes
each with an encoder (standard message frame 3) and I/O data:
Message frame type Description
4 axes each with an encoder, standard mes-
sage frame 3 + IO, PDA-5/9 O/I 1/1
4 x standard message frame 3 and 1 PDA
word each for digital I/O data
PDA x/y number of process data words, x: Setpoint, y: Actual value
