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) is 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.
