TTIM (TOTALIZING TIMER) instruction,
SEND(90)/RECV(98)/CMND(––) (network
communications) instructions, PMCR
(PROTOCOL MACRO) instruction,
STUP(––) (CHANGE RS-232C SETUP)
instruction and 19 floating-point math
instructions available.
One built-in peripheral port
Supports the following communications: Peripheral bus, Programming Console bus, Host Link,
no-protocol
One built-in RS- CQM1H-CPU61/51/21:
232C port Supports Host Link,
no-protocol, NT Link (1:1
mode) and 1:1 Data Link
communications.
CQM1H-CPU11: None
Note Programming
sole functions support-
ed from a PT (except
when pin 7 on the DIP
switch is OFF).
Serial Commu- Host Link, no-protocol, 1:1
nications Board Data Link, NT Link (1:1
(available sepa- mode, 1:N mode) and proto-
rately): 1 RS- col macro communications
232C port and supported.
1 RS-422A/485
port
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 Data transfer is possible
(1:1 mode, 1:N without program between the
mode) 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.
AC power supply: 10 to 25 ms
DC power supply: 5 to 25 ms

The instructions on the left are not supported
by the CQM1.
One built-in Supports Host Link and
RS-232C port no-protocol
communications (except
CQM1-CPU11/21-EV1).
CQM1-CPU4@-EV1 also
supports 1:1 Data Link, NT
Link (1:1 mode)
