M550/M560 Analogue output Override Function
(used for calibrating outputs)

A value entered here forces the analogue output to a fixed state.
Examples. (20mA Outputs)
Value to enter to force an output to 20mA is 3412 (0D54h)
Value to enter to force an output to zero is 2047 (07FFh)
Value to enter to force an output to -20mA is 682 (02AAh)
For this function, both the General Pass Code and the Analogue Calibration Pass Code need to be valid.

Example Coding
To set the output of D2A channel 1 to zero

Slave Address = 1
Writing To 4X Registers - code 16 (10 hex)
Value to write = 2047
