6-2 Built-in Outputs
6-2-1 Overview
There are 3 kinds of built-in outputs:
• General-purpose outputs
• Pulse outputs
• Variable duty ratio pulse outputs (PWM(891) outputs)
The built-in outputs are allocated bits 00 to 05 of CIO 2961. The Pulse Output
Instructions must be executed to specify which kind of input is used for each
bit.
6-2-2 General-purpose Outputs
Overview
This function is used to output standard output signals. The output point is
refreshed when the allocated bit goes ON or OFF.
Bit Allocations
Procedure
Restrictions on General-purpose Outputs
• General-purpose outputs 0 to 3 cannot be used if pulses are being output
through those points by the pulse outputs.
• General-purpose outputs 4 and 5 cannot be used if variable duty ratio
pulses (PWM(891) outputs) are being output through those points.
• General-purpose output 4 (5) cannot be used when the origin search
function is enabled for pulse output 0 (1) and the Error Counter Reset
Output is being used (origin search operating mode set to 1 or 2.)

Ladder program
•
OUT0 to OUT5 (CIO 2961 bits 00 to 05)
•
Connect to the selected terminals between
OUT0 and OUT5.
•
Use the general-purpose outputs in instructions
such as OUT.
•
To use the immediate-refreshing variation, add the
"!" prefix to the instruction. For example: !OUT.
Note: Immediate refreshing cannot be performed by
the IORF(097) instruction.
