The CQM1H is a compact Programmable Controller (PC) that supports com-
munications and other advanced functions. It is a package-type PC that is
mounted to DIN Track to control small to medium-size machines.
A flexible system configuration is enhanced by serial communications with a
protocol macro function, user-installed boards called Inner Boards, network
communications, a wide range of monitoring and setting methods, higher
speed, and larger capacity. These features enable added-value machine con-
trol.
• Mount up to two Inner Boards to add communications or control functions.
Communications Functions: Serial Communications Board
Control Functions: High-speed Counter Board, Pulse I/O Board, Absolute
Encoder Interface Board, Analog Setting Board, and Analog I/O Board
• Mount a Controller Link Unit to connect to a Controller Link Network.
• Connect simultaneously to both a Programming Device and a Program-
mable Terminal (PT).
• Obtain higher speed and capacity in comparison to the CQM1: 1.25 times
faster, twice the program capacity (15.2 Kwords), twice the I/O capacity
(512 points), and twice the data memory capacity (12 Kwords).
• Use new instructions.
• Maintain compatibility with previous models of PC.
The CQM1H does not require a Backplane and is constructed by connecting
Units via connectors on the sides of the Units, allowing flexible system config-
uration. The CPU Unit contains 16 built-in DC input points. Two Inner Boards
can be mounted in the CPU Unit. One Controller Link Unit (a Communications
Unit) and a combined maximum of eleven I/O Units and Dedicated I/O Units
can also be connected. If an Expansion I/O Block is used, a maximum of 16
Units can be connected. (See 1-2-1 Basic Configuration.)
Note 1. The CQM1H is mounted to DIN Track.
2. Only the CQM1H-CPU51/61 CPU Units support Inner Boards and the
Controller Link Unit.

Execution times have been reduced to 0.375 µ s for the LOAD instruction
(from 0.50 µ s for the CQM1), to 17.7 µ s for the MOVE instruction (from
23.5 µ s) and to 0.70 ms for overseeing (from 0.80 ms), reducing the total
cycle time by approximately 25%.
• The program capacity, the I/O capacity, and the data memory capacity
have all been approximately doubled. The program capacity has been
increased to 15.2 Kwords (from 7.2 Kwords for the CQM1); the I/O capac-
Units assembled via connectors on their sides.
