Connection Examples for Multidrop
(Normal)
Details on the procedure for connecting an
RS-232C/RS-422(485) converter and performing communica-
tions with several V530-R150s from one host (computer or Pro-
grammable Controller) are given here.
Unit numbers 00 to 31 can be set for the V530-R150. All commu-
nications data between the host includes unit numbers, and
commands will be ignored by V530-R150s whose unit numbers
differ from those contained in the command data. Communica-
tions data formats for multidrop are the same as for other com-
munications except for the inclusion of the unit number.
Reading data is read with the sending of a polling (read) com-
mand from the host side. Even if the data is read correctly, it is not
output until polling commands are given.
System Configuration
The number of RS-232C/RS-422(485) converters/adapters
required will be one more than the number of V530-R150s in the
system. An example of a configuration using OMRON’s
