For communications, the master (PLC) sends a
command to the slave (VS-606V7) and the slave
responds to it. The configuration for sending and
receiving is as shown to the right. The length of
the data varies according to the contents of com-
mands (functions).
The interval between messages must be main-
tained at the following amount.
