Note The standard protocols are provided with the CX-Protocol and Serial Commu-
nications Unit.
CompoWay/F
(Host Function)
The CJ-series CPU Unit can operate as a host to send CompoWay/F com-
mands to OMRON components connected in the system. CompoWay/F com-
mands are executed by using the CompoWay/F send/receive sequences in
the standard protocols of the protocol macro function.
Serial Gateway Mode
When using CPU Units with unit version 3.0 or later (peripheral port and RS-
232C port), the received FINS message is automatically converted into Com-
poWay/F according to the message (see note). When Serial Communications
Boards/Units with unit version 1.2 or later are used, the received FINS mes-
sage is automatically converted into either CompoWay/F, Modbus-RTU, Mod-
bus-ASCII, or Host Link FINS according to the message.
Note CPU Units with unit version 3.0 or later (peripheral port and RS-232C port)
support automatic conversion into CompoWay/F only (automatic conversion
into Modbus-RTU, Modbus-ASCII, and Host Link FINS is not possible).
