-OM1 Interface Option
Communications:
The -OM1 Option uses the Omron Host Link protocol for communicating to
all suitably equipped Omron PLC’s. The Omron Host Link port is connected
to the T-60 or T-61’s COM1 port via the supplied cable. Both the T-60 and
T-61 auto detect the communication parameters, so no setup is needed to get
the two devices communicating.
Connections:
The -OM1 Option comes with the proper cable to interface to a Host Link
equipped PLC. For those who need to change the length of the cable, the
proper connections are shown below:
Command Variations:
The following table will help the terminology of the previous sections make
more sense with respect to the Omron Host Link documentation. It is a cross
reference between the Memory Type in the PLC documentation and the cmd
for the CALL PLCREAD and CALL PLCWRITE commands.
