In the top half, the Slave function (MSG-RCV) parameters are set in the first scan after star-
tup.
In the lower half, messages are transmitted. At this time, the Communications Module type
and the protocol type are set in the device type (DEV-TYP) and protocol type (PRO-TYP),
respectively, as the Master function inputs.
With the protocol type, the setting value of the Extended MEMOBUS, MEMOBUS,
MELSEC, and OMRON protocols is 1. This value is specified in the transmission parameter
setting of each Communications Module. See the section on the transmission definitions for
each Communications Module.
