The number of recording channels is the total of all the channels that are recording.
The number of set points is set unit of channels. (When correction mode is off, the number
of set points is zero.)
The number of wireless input units is the number of recognized units.
Example 1: When recording measurement data for 50 communication channels, 30
calibration correction points (4 points/ch), 10 wireless input units, and 10 groups Here we
assume that there are no messages, alarms, loops, program patterns, control summaries, or
control alarms.
