The control and status bytes (CB1 and SB1) for channel 1 in the process data mode [
}
39] and for register
communication [
}
40] are described below.
Channels 2 to 8
The control and status bytes of channels 2 (CB2 and SB2) to 8 (CB8 and SB8) have the same structure as
the control and status bytes of channel 1.

Terminal compensation
function is activated A gain and offset calibration of the terminal can
be carried out with the control byte in process
data mode. The code word must be entered in
register R31 so that the calibration can be
carried out.
The parameter will only be saved permanently
once the code word is reset!
