CS1

C--12

CS1D Duplex System CPUs for Increased Reliability

J Features and Functions

•

High reliability for a no-fail redundant system. The CS1D offers

redundancy of CPUs, Power Supplies, and Controller Link

Network.

•

CPUs, Power Supplies, Communication Modules, Basic and

Special I/O Modules can be replaced during system operation.

Hot standby technology allows easy and fast maintenance.

•

Hot standby system adopted for CPU duplexing

•

Same support software as CS1 (CX-Programmer).

•

Complete compatibility among CS1 I/O Modules.

•

Same speed, I/O capacity and memory size as CS1.

•

Built-in peripheral and RS-232C port.

•

Inner board compartment for additional communications ports.

•

Basic specifications for CS1D Duplex CPUs.

Note: The available data memory capacity is the sum of the Data Memory (DM) and the Extended Data Memory (EM).

With the CS1 PLCs, Memory Cards and specified ranges of the EM Area can be used as file memory. File memory can be used to

store the entire user program, I/O memory contents, and/or parameter area contents.
