About this Manual:
This manual describes the programming of the CS1G/H-CPU@@-EV1 and CJ1G/H/M-CPU@@ CPU
Units for CS/CJ-series Programmable Controllers (PLCs) and includes the sections described on the
following page. The CS Series and CJ Series are subdivided as shown in the following table.
Please read this manual and all related manuals listed in the table on the next page and be sure you
understand information provided before attempting to install or use CS1G/H-CPU@@-EV1 or CJ1G/H/
M-CPU@@ CPU Units in a PLC System.
This manual contains the following sections.
Section 1 describes the basic structure and operation of the CPU Unit.
Section 2 describes basic information required to write, check, and input programs.
Section 3 outlines the instructions that can be used to write user programs.
Section 4 describes the operation of tasks.
Section 5 describes the functions used to manipulate file memory.
Section 6 provides details on advanced functions: Cycle time/high-speed processing, index registers,
serial communications, startup and maintenance, diagnostic and debugging, Programming Devices,
and CJ Basic I/O Unit input response time settings.
Section 7 describes the processes used to transfer the program to the CPU Unit and the functions that
can be used to test and debug the program.
The Appendices provide a comparison of CS/CJ-series, restrictions in using C200H Special I/O Units,
and changes made to Host Link Systems.
