Control/Status byte
CONTROL byte in
process data transfer
Gain and offset adjustment
The control byte is transferred from the controller to the terminal. It can be
used in the register mode (REG = 1) or in process data transfer (REG = 0).
The gain and offset of the terminal can be adjusted with the control byte
(process data transfer). The code word must be entered in R31 to enable
adjustment of the terminal. The terminal’s gain and offset can then be
adjusted.
The parameters are not permanently stored until the code word is reset!
