Programmable Controller SYSMAC CJ Series; Omron to Release Pulse I/O Modules for CJ2M CPU Unit
KYOTO, Japan - (BUSINESS WIRE) - OMRON Corporation (TOKYO:6645)(ADR:OMRNY) today announced plans to
release the following products in Japan* on July 30.
Pulse I/O modules for SYSMAC CJ2M Series Programmable Controllers
-
Model: CJ2M-MD211 (Sinking Output Type)
-
Model: CJ2M-MD212 (Sourcing Output Type)
These modules have configurable pulse I/O functions and a dedicated
high-speed interface to the CJ2M CPU units. One or two modules can be
attached to CJ2M CPU Units, extending the CPU functionality with
position control of up to four axes.
Background
Driven by the severe economic conditions in recent years, users of
manufacturing systems are increasingly seeking cost reductions. Their
machine suppliers therefore also need to continuously improve their cost
competitiveness. An important step in production machinery cost
reduction is the standardization of control systems, allowing efficient
re-use of designs and programs. The scalability of Omron's control
systems allows the machine builder to develop from low-end to extensive
high-speed machines with minimized development effort.
For small-scale and simple position control applications with one or two
axes, the use of compact controllers with pulse I/O functions built into
the CPU is commonplace. However, such built-in functionality is usually
limited to basic PLCs, with a small program capacity and limited
expansion options. For more complex tasks with more axes to be
controlled, high-end modular controllers are required, expanded with
intelligent position control modules.
The new CJ2M pulse I/O modules provide an effective way to add position
control functionality to any of the CJ2M CPU units as of unit version
2.0. With program capacities ranging from 5K to 60K steps, and the
possibility of expansion with a wide variety of I/O units, this PLC
family offers cost-efficiency without the limitations of a fixed
built-in I/O configuration. With CJ2M's wide variety of capacities and
communication interfaces, machines requiring up to 4 axes of position
control can be designed in a modular way using the new pulse I/O modules.
To expand a system beyond four axes, or to further increase speed or
accuracy, you can use additional position control units, either with
pulse I/O or high-speed network interfaces.
*　Availability: CJ2M-MD211/-MD212 models will be available from
September 1,　2010.
Major features
1. Choose the CPU to match your needs
Up to two pulse I/O modules can be mounted on any CJ2M CPU Unit, with a
choice of 5 program capacities from 5K steps to 60K steps. Position
control commands of the CJ2M CPU Unit can be used to directly control up
to for four axes, doubling the capacity of the older CJ1M series.
2. High-speed and high-accuracy pulse output
The output functions of the pulse I/O modules contribute to shortening
machine cycle times with high-speed start-up. The pulse control cycle of
1ms and an output frequency of up to 100 kpps ensure smooth responses,
contributing to high-accuracy positioning. The new Interrupt Feeding
Instruction (IFEED) eliminates delays caused by the interrupt startup
time or the occurrence of other interrupts, allowing improved feeding
accuracy.
3. Smooth acceleration and deceleration
In addition to the Trapezoidal acceleration/deceleration profiles common
in basic position control applications, the new pulse I/O modules also
offer S-curve acceleration/deceleration. The smoother transitions reduce
mechanical stress and vibrations, improving production quality and
reducing machine wear.
4. Flexibility in functionality
The pulse I/O module's inputs can be configured to work in four
different modes: normal input, interrupt input, quick-response input,
and high-speed counter input. Combinations of various types of inputs on
a single pulse I/O unit allow you to adapt the PLC to the machine,
without changing hardware.
5. Easy, yet powerful programming, monitoring, and debugging
Dedicated instructions plus a library of OMRON Function Blocks greatly
reduce programming effort. Enhanced data tracing functions in CJ2M and
CX-Programmer V9 can be used for monitoring or detailed analysis of
position control behavior at PLC cycle time level.
