1794-OE8H Calibration Item Byte Channel-Mask
The Calibration item byte channel-mask uses each bit of the byte to
correspond to one channel: where 1 is calibrate this channel and 0 is do not
calibrate this channel. The LSB corresponds to channel 0, e.g., 0x03 >
channel
0 and 1 have to be calibrated. Only one channel can be calibrated at a time. If
there are more channels selected within the calibration commands, the I/O
module signals an error.
