Overview
This manual explains the programming methods and data used for control of the following
modules and PID control using structured programming technique.
• Precautions on using instructions
For details of the specifications, functions, and operating timing of each
instruction, refer to the related manuals of each module.
'MANUALS'
Function/module for explaining an
instruction
Processing performed by the instruction Reference
Analog module
• Switches the mode. (Offset/gain setting mode or normal
mode)
• Reads the user range setting offset/gain value.
• Restores the user range setting offset/gain value.
Section 5.1
Serial communication module
• Sends and receives data to and from an external device.
• Registers and reads user frames.
Section 5.2
Modem interface module
CC-Link system master/local module
• Reads and writes data from and to an intelligent device
station on the CC-Link system.
• Reads and writes data from and to the auto-refresh buffer
memory at the master station.
• Sets the network parameters.
Section 5.3
Ethernet interface module
• Sends and receives data to and from an external device.
• Reads and writes data from and to another station on the
CC-Link IE controller network or MELSECNET/H network
system.

Section 5.4
MELSECNET/H network module
CC-Link IE controller network module
PID control instruction
• Sets PID control data and performs PID operation for
inexact differential and exact differential.
• Stops and starts operation of the specified loop.
• Changes the parameter of the specified loop.
Section 5.5
Section 5.6
Positioning module
• Restores the absolute position of the specified axis.
• Starts positioning of the specified axis.
• Executes teaching of the specified axis.
