Sequence control module (S3)

This module has high-speed sequence control functions.

High-speed processing

The S3 has a high-speed IEC language processor for processing basic commands at 40 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 S3 has an RS-485 port for communication with a touch-panel or a higher-level computer through a computer link.

A single unit may consist of up to three modules (S3, L3, C3). 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 can be controlled from the S3, L3, and C3 modules. Up to 9 I/O modules can be installed in the base unit, or up to 11 in an expansion unit. Up to 28 expansion units can be connected so that a total of 317 I/O modules can be controlled.

Intelligent serial PI/O

Intelligent serial PI/O can be controlled from the L3 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.

F series PI/O

The F series is the serial PI/O controllable from the L3 module. An analog I/O system permits mixed 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 serial 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 S3 and L3 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-netTM also permit dual transmission line configuration.
