Supports Host Link,
no-protocol, NT Link (1:1
mode) and 1:1 Data Link
communications.

No-protocol
Up to 256 bytes can be sent or received with special instruction. Header codes and end codes
can be set. Transmission delay time setting available.
Host Link
All of the CPU Unit’s I/O memory areas, and the user’s program can be accessed using Host
Link commands.
NT Link
(1:1 mode, 1:N
mode)
Data transfer is possible
without program between the
PC and an OMRON PT. The
ratio of PCs to PTs can be
one-to-one or
one-to-many.
The 1:N-mode NT Link
connections are possible
only for the RS-232C port or
RS-422A/485 port on the
Serial Communications
Board.

Protocol macro Protocol macro communica-
tions supported using the
RS-232C port or RS-422A/
485 port on the Serial Com-
munications Board (CQM1H-
CPU51/61 only).
Sending and receiving data
is possible using one
instruction via a user-defined
protocol from the ladder
program.
