The Controller's built-in RS-485 interface allows the connection of up to 10
Controllers to a single host device, such as a general-purpose computer or a
PLC. The RS-485 cable can be extended up to a total length of 300 m.

Note The RS-232C interface does not support 1-to-N connections. Therefore, it is
necessary to employ appropriate interfaces for data conversion, such as an
RS-232C to RS-485 Converter. Use OMRON's RS-232C to RS-485
Converters or equivalent models. If connecting a 2-wire system between the
Controller and the host using an RS-232C to RS-485 Converter, switch the
host to receive within 5 ms after sending a command to the Controller.
Failure to do so may result in loss of communications with the Controller.
