High Performance
Ultimate Controller Performance

  • In order to create facilities that have the production capability to withstand sudden changes in demand, or to create machinery that is easily distinguished from that created by market competitors, a top-speed controller that can deliver the performance required to support these needs is required. The CS1 PLCs have been equipped with the highest I/O responsiveness and data control functionality to significantly reduce processing time and to control machinery movement with greater precision.

Human Efficiency
User-friendly Development Environment

  • In order to allow easier development of complex programs, bin addition to an integrated Windows-based development environment, the new PLCs are equipped with a variety of instructions. Structured programming functionality has been improved to allow programs to be reused with greater efficiency and thereby reduce labor requirements and cut costs.

Efficient Use of Valuable Assets

  • The know-how that our customers have accumulated through the years forms the core of their competitive strength. At OMRON, we believe in enhancing this knowhow to the utmost. The key to doing this is 100% upward compatibility. CS1 PLCs allow existing Units and programs to be used without any changes.

Use the improved CS1 PLCs to scale advanced systems to the optimum size.

Wide Lineup Makes It Easy to Build the Optimum System

  • A total of nine CPU Unit models provide for a wide range of applications, from small-scale systems to large. The lineup also includes Memory Cards, Serial Communications Boards, and a wide selection of Special I/O Units that can be used with any CPU Units to flexibly build the system that meets the requirements.

Two Series of Expansion Racks Up to 50 m Long for Long-distance Expansion with Up to 72 Units and 7 Racks

  • With an expansion capacity of up to 80 Units and 7 Racks over a distance of 12 meters, the CS1 can meet large-scale control needs. Alternatively, an I/O Control Unit and I/O Interface Units can be used to connect two series of CS1 Longdistance Expansion Racks extending up to 50 m each and containing a total of up to 72 Units and 7 Racks. CS1 Basic I/O Units, CS1 Special I/O Units, and CS1 CPU Bus Units can be mounted anywhere on the Racks and programmed without being concerned about special remote programming requirements. 
    Note:C200H Units cannot be mounted on the Longdistance Expansion Racks.

Control Up to 960 Points with Units Mounted to the CPU Rack

  • The CS1 provides a high level of space efficiency. As many as 960 I/O points can be controlled by simply mounting ten Basic I/O Units, with 96 I/O points each, to the CPU Rack. Alternatively, as many as 80 analog I/O points can be used by mounting five Analog Input Units and five Analog Output Units.

Improved Refresh Performance for Data Links, Remote I/O Communications, and Protocol Macros

  • In the past, I/O refresh processing with the CPU Bus Unit only occurred during I/O refresh after instructions were executed. With the new CS1, however, I/O can be refreshed immediately by using the DLNK instruction.
  • Immediate refreshing for processes peculiar to the CPU Bus Unit, such as for data links and DeviceNet remote I/O communications, and for allocated CIO Area/DM Area words when instructions are executed, means greater refresh responsiveness for CPU Bus Units.

Faster Instruction Execution and Faster Overall Performance

In addition to further improvements to the instruction execution engine, which is the core of overall PLC performance, the high-speed RISC chip has been upgraded to realize the fastest instruction execution performance in the industry. Also, the new models have a mode where instruction execution and peripheral processing are processed in parallel, enabling balanced improvements in overall speed.

  • Common Processing: 0.3 ms 
  • PCMIX Value: 16
  • Cycle Time (Cycle time for 128 inputs and 128 outputs): 
  • Basic instructions only: 38 Ksteps/ms.
  • Including special instructions: 22 Ksteps/ms.
  • LD Instruction Processing Speed: 20 ns.
  • OUT Instruction Processing Speed: 20 ns.
  • Subroutine Processing Speed: 2.1 μs.

Further improvements to Communications functions. Seamless networks increase production site transparency.

High-speed, High-capacity Data Links between PLCs via EtherNet/IP

  • EtherNet/IP is supported. EtherNet/IP is a global-standard network that uses cutting-edge general Ethernet technology for control and information network integration. This enables data links between PLCs, data links between a PLC and multi-vendor devices, and communications between PLCs and PTs over a general Ethernet network.

CompoNet Greatly Advances Wiring Reductions, Greater Information Handling, and Standardization

  • CompoNet is a multi-vendor network for bit-level control of approximately 1,000 points in 1.0 ms. It supports message communications at the sensor and actuator levels. Maintenance information can be controlled in each Slave for preventative maintenance of equipment.

Flexible System Building Based on the DeviceNet

  • The CS1 Series supports the worldwide multivendor bus standard, DeviceNet. Component connections in a multivendor environment are greatly enhanced by connecting to up to 64 nodes for a wide range of FA applications, and by device profiles and configurator tools that ensure high reliability and easy maintenance.
  • Production systems can be configured even more flexibly by incorporating products such as the MULTIPLE I/O TERMINAL.

Functions for Better Ethernet Support

  • Ethernet is becoming increasingly important standard for information networks. Up to eight socket interfaces for TCP/IP and UDP/IP are supported, in addition to FINS messages, FTP file transfers, and mail notification, so that production management can now be organically linked with the production site.

The Solution for Communicating across Network Levels

  • The CS1 enables FINS message communications across a maximum of eight levels (See note.) (using CX-Programmer Ver. 4.0 or higher) in comparison with three levels in previous OMRON systems Expansion up to eight levels lets you build a seamless communications system for sending FINS messages across multiple levels of Ethernet and Controller Link networks.
      Note: For CPU Unit Ver. 2.0 or later.

A Wide Range of Systems, from Small-scale to Large

  • OMRON offers a full lineup of reliable PLCs including the "flagship" CS1 Series, and ranging from the small scale CP1H to the large-scale CV Series. The CS1 Series meets the needs not only of small-scale to large-scale systems, but of distributed systems as well. This allows the construction of the optimum system for the scale and applications of the production site.

Hot Standby System Adopted for CPU Unit Duplexing

  • When a problem occurs in the CPU Unit, the system instantly switches control to the other CPU Unit, enabling      continuous operation with minimal effect on the system.
  • Because there is no need for special duplex programming, the design process is simple and design steps are reduced.
  • The system can also be configured with only one each of the CPU, Power Supply, and Communications Units. This lets 
  • you optimize the system cost by selecting the Units that you need. (The Duplex Unit must be used even when using only one each of the CPU, Power Supply, and Communications Units.)

Duplex operation is possible for any or all of the following: CPU Units, Power Supply Units, and Communications Units.

  • Use duplex operation for the CPU Unit, power supply, or communications depending on system requirements for reliability, costs, and functionality. For example, use duplex operation for all of these for systems that must never go down or use duplex operation for only the power supply (which has a relatively short service life). Just build in the redundancy required by the system.

Duplex Ethernet for Greater Information Network Reliability

  • With redundant networks and Communications Units, communications will continue even if a network line is broken or one of the Communications Units fails. The communications path is automatically selected for each communications process (as opposed to switching the entire line), to enable creating a highly reliable network even against a network line broken in more than one location. 
  • The CS1D-ETN21D and CS1D CPU Unit version 1.1 or higher are required for a duplex Ethernet network.

Position Control Unit with MECHATROLINK-II interface

Single Cable Connection and Flexible Routing

  • With MECHATROLINK-II*, the Servo Drive can be easily connected with a single cable (2-core shielded twisted pair cable). The wire savings over the total length of 50 m (or 30 m for 16 axes) enables Racks to be more freely located.

Time Saved in Startup and Maintenance

  • Servo Drive parameters can be set from the PLC.
  • Settings and adjustments can be made from one location, without connecting the Support Software to individual Servo Drives. In addition, Servo Drive alarm status, speed, and torque monitoring can be centralized at the PLC.

Position Control Units

Two Types of Outputs and Control of 1, 2, or 4 Axes

  • Select from 1-axis, 2-axis, and 4-axis models with either open-collector output or line-driver output to suit a number of different applications.

A Variety of Positioning Functions

There are 2 operating modes: direct operation (position, speed, acceleration, and deceleration data specified from the ladder program), which is effective for setting target positions, speeds, and acceleration rates immediately or during operation, and memory operation, where fixed patterns are stored beforehand in the Unit and used for operation. There are also a variety of positioning functions, such as interrupt feeding, which is effective for feeder control, and forced interrupt, which is useful in emergencies.

Motion Control Unit with MECHATROLINK-II interface

Easy System Construction

  • Up to 30 physical axes and two virtual axes, making a total of 32, can be controlled, and the servo interface is handled by high-speed servo communications (MECHATROLINK-II*). This makes it possible to control multiple axes with less wiring.

Easy Data Control

  • High-speed servo communications lets you read programs and parameter settings from CX-Programmer on a PC.
  • You can also read and track the operating status of parameter settings inside the Servo Driver.

Easy Motion Control

  • Motion control, including positioning, synchronizing (electronic gears, electronic cams, tracking), speed, and torque control, can all be handled by the CS1. Eight motion tasks can be used for simultaneous motion program execution.

Motion Control Units

Easy Programming with G Language and Multitasking

  • The Motion Control Units use G language to ensure easy programming. The Units have a large programming capacity of up to 100 programs and 2,000 program blocks, and allow independent operation of 4 tasks.

High-speed Interlocks

  • Interrupt programs can be executed from the motion control program using D codes (interrupt codes). Easy, fast interlocks ensure greater production efficiency. Synchronous control (electronic gears, electronic cams) is also possible.
