Details on the procedure for connecting an RS-232C/RS-422(485)
converter and performing communications with several V530-R150s
from one host (computer or Programmable Controller) are given here.
Unit numbers 00 to 31 can be set for the V530-R150. All communica-
tions 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. Communications data formats for
multi-drop are the same as for other communications except for the
inclusion of the unit number.
Reading data is read with the sending of a polling (read) command
from the host side. Even if the data is read correctly, it is not output
until polling commands are given.
