The following selections use the OIT’s 9-pin male connector labeled
PLC[RS485]
PC[RS232]
.
RS485 default:
The selected protocol determines 2 or 4 wire.
RS485 4W:

Select
baud rate
,
parity,
data bits
, and
stop bits
. Use Maple Systems’ Controller Information
Sheets or the PLC manufacturer’s operations manual for information on the communications
parameters required by the PLC. These parameters have to match the PLC settings.
5.
Parameter 1 and 2 are used to configure a delay time for the OIT. The time set on these
parameters is the time the OIT will wait before sending another request for information.
Parameter 1 is used in the Protocol level and Parameter 2 is used at the Operating System
level. Refer to the Controller Information Sheets if these parameters are required. Parameters
3-6 are not used.
6.
Set the
OIT Station No
. used by some protocols that require the OIT to have a unique network
address. Consult your Controller Information Sheets for information on the protocols to
which this parameter applies.
7.
Set the
PLC Station Number
or
Node Address
of the PLC with which the OIT will
communicate.
8.
Multiple HMI and HMI-HMI link speed:
Used when connecting multiple OITs to a single
PLC. Disable this setting if you are connecting only a single OIT to a PLC. For more
information on connecting multiple OITs, see
Connecting Multiple OITs to one PLC
at the
end of this chapter.
9.
Connect I/F:
Allows selection of the method by which multiple OITs can be daisy-chained.
The options are
Serial
or
Ethernet
. If
Ethernet
is selected, configure the
Local
and the
Server
IP addresses
. For more information, see
