2-1-12 Basic Ladder Programming Concepts

The maximum program capacities of the CS/CJ-series CPU Units for all user
programs (i.e., the total capacity of all tasks) are given in the following table.
All capacities are given as the maximum number of steps. The capacities
must not be exceeded, and writing the program will be disabled if an attempt
is made to exceed the capacity.
Each instruction is from 1 to 7 steps long. Refer to 10-5 Instruction Execution
Times and Number of Steps in the Operation Manual for the specific number
of steps in each instruction. (The length of each instruction will increase by 1
step if a double-length operand is used.)

Note Memory capacity for CS/CJ-series PCs is measured in steps, whereas mem-
ory capacity for previous OMRON PCs, such as the C200HX/HG/HE and CV-
series PCs, was measured in words. Refer to the information at the end of10-
5 Instruction Execution Times and Number of Steps in the Operation Manual
for your PC for guidelines on converting program capacities from previous
OMRON PCs.
Instructions are executed in the order listed in memory (mnemonic order). The
basic programming concepts as well as the execution order must be correct.
