mode Serial Gateway Not supported Supported
The received FINS command can be converted
into serial communications protocol and then con-
verted into either of the following protocols (using
the Serial Gateway mode).
• CompoWay/F
• Modbus-RTU
• Modbus-ASCII
• Host Link FINS (This protocol can be used to
make the PLC function as the Host Link Mas-
ter.)
The Serial Gateway can also be used in protocol
macro mode. This option enables, for example, pro-
gramming or monitoring of a serially connected
PLC from a CX-Programmer that is connected to
the PLC during execution of protocol macros (e.g.,
Host Link Master).
Host Link 1:1 protocol Not supported (1:N
Host Links only) Supported
This protocol functions the same as the 1:1 Host
Link supported by the earlier C200H, C1000H, and
C2000H Series, thereby enabling the use of host
computer programs for 1:1 Host LInks created
using these earlier PLCs.
Note: CS/CJ-series, C200HS/HX/HG/HE(-Z),
CPM
@
, CQM1
@
, and CVM1/CV Series all support
1:N Host Links only. C200H and C500 Host LInk
Units support both 1:1 and 1:N Host Links.
Host Link
compatible
device selec-
tion Not supported (not
completely compati-
ble with C-series
Host Link and CVM1/
CV-series Host Link) The compatible device mode enables full compati-
bility of Host Link functions (see note) with C-series
Host Link and CVM1/CV-series Host Link.
Note: E.g., differences in specifications for delimiter
words in response frame data
No-protocol Not supported Supported, but only when using a CS/CJ-series
CPU Unit with unit version 3.0 or later.
(The no-protocol mode that was previously possi-
ble only at the built-in RS-232C port of CPU Unit is
now available for the Serial Communications
Boards and Units.)
This protocol is mainly used for communications
with devices that perform input or output only, such
as bar code readers and printers.
This mode enables no-protocol communications
even if the CPU Unit’s built-in RS-232C port is
being used for another application.
