CJ2 CPU Unit Instruction Execution Times and Number of

The following table lists the execution times for all instructions that are sup-

ported by the CPU Units.

The total execution time of instructions within one whole user program is the

process time for program execution when calculating the cycle time (See

Note User programs are allocated tasks that can be executed within cyclic tasks

and interrupt tasks that satisfy interrupt conditions.

Execution times for most instructions differ depending on the CPU Unit used

and the conditions when the instruction is executed.

The execution time can also vary when the execution condition is OFF.

The following table also lists the length of each instruction in the Length

(steps) column. The number of steps required in the user program area for

each instructions depends on the instruction and the operands used with it.

The number of steps in a program is not the same as the number of instruc-

1. Most instructions are supported in differentiated form (indicated with ↑, ↓,

@, and %). Specifying differentiation will increase the execution times by

the following amounts.

2. Use the following time as a guideline when instructions are not executed.
