Sequence control module (S2)

This module has high-speed sequence control functions.

High-speed processing

The S2 has a high-speed IEC language processor for processing basic commands at 80 ns. The main processor performs parallel processing of communications, etc. during user program execution so that total scan time, including overhead, can be sharply reduced.

Multitask function

Two or more different tasks can be executed in parallel. An optimum control cycle can be selected as appropriate to a control object or control details.

Realtime online trace function

Data is collected and saved at the same time as program execution after its command is given. Data online trace is possible while the program is being executed.

Computer link port provided

The S2 has an RS-485 port for communication with a touch-panel or a higher-level computer through a computer link.

Computer module (C2)

This module has computer functions.

Compact, space-saving computer

The module, PC/AT compatible, has a keyboard I/F, mouse I/F, FDD I/F, Ethernet port, COM port, USB port, and PCMCIA slot. With the RAS function of industrial personal computers built in, the module may be used as a controller having a large-capacity HDD and memory. The compact body saves space in using the module as a personal computer to be built into a device.

High-speed CPU

The C2PU37 has the Pentium® III 500 MHz processor. The Ethernet port is good for 100 Mbps. The Windows® 2000 model has a USB port as a standard support feature.

I/O modules accessible

The C2 module has an I/O access driver as a standard feature for input to and output from parallel I/O modules. (*1) The module can be used not simply as a computer but also as a controller.
*1 Some I/O modules are not accessible by the computer module.

Automatic shutdown

The PS694 is available as power module for the C2. The PS694 has a built-in battery. If power fails during system operation, the operating system is automatically shutdown without power interruption. This protects the hardware and data from destruction without a no-break power supply (UPS)

A single unit may consists of up to three modules (S2, L2, C2). Each module has a common memory area, and data can be easily sent and received between modules as global variables through registering with the engineering tool. A multiple configuration of the same module permits high-speed distributed processing.

Basic system configuration


Parallel I/O and serial I/O are available.

Parallel I/O

Parallel I/O modules can be controlled from the S2, L2, and C2 modules. Up to 8 I/O modules can be installed in the base unit and in an expansion unit respectively. Up to 3 expansion units can be connected so that a total of 32 I/O modules can be controlled.

* Some I/O modules are not accessible by the computer module.

Parallel I/O module specifications

Intelligent serial PI/O

Intelligent serial PI/O can be controlled from the L2 module. Online swap that is essential to continuous deployment of meter control, I/O module duplex configuration, and duplex bus configuration ensure high reliability. The intelligence function responds to the diversity of signals from the field, making the PI/O module useful in a wide range of applications.

Intelligent serial PI/O module specifications

F series PI/O

The F series is the serial PI/O controllable from the L2 module. An analog I/O system permits presence of two or more different signals, using a signal condition for each signal and thus reducing I/O module loss. A digital I/O system employs OMRON I/O relay terminals (of the G7TC series), which help simplify signal wiring and raise installation efficiency. The F series PI/O can be mixedly installed with the conventional intelligent series PI/O, so your assets can be effectively made use of.



Ethernet is a surveillance control LAN used for connection to a higher-level HMI system. Ethernet modules of 100 Mbps and 10 Mbps are available. Transmission lines may be of single or dual configuration as desired to satisfy your needs for highly reliable transmission.

The S2 and L2 modules can be configured duplex. Two base units of the same configuration of standby redundancy type can deal with a failure with one of them, in which case control is switched from the defective unit to the other unit.
As for I/O, intelligent serial PI/O duplex configuration is possible. Unit connecting serial buses are duplex in standard configuration, and each I/O module can also be configured duplex. The surveillance control LAN Ethernet and the control LAN TC-net™ also permit dual transmission line configuration.
