1-1 Features
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.
Flexible System
Configuration
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.
Higher Speeds and
Greater Capacity
Execution times have been reduced to 0.375
µs for the LOAD instruction
(from 0.50
µs for the CQM1), to 17.7 µs for the MOVE instruction (from
23.5
µs) 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.
