11.2 Example of Communications Between the Master Station and a Head Module

This section describes an example of communications where D/A conversion in CH1 and
CH2 of a D/A converter module (L60DA4) are enabled and analog values are output from the
channels.
If an error occurs while a digital value is written, the output module (QY10) mounted to the
master station will display an error code in BCD format.
Set a scaling value only for CH1 and configure the warning output setting only for CH2.
