Explanation Content in This Manual

This manual explains the programming methods and data used for control of the following 
modules and PID control using structured programming technique.

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.

Positioning module

• Restores the absolute position of the specified axis.
• Starts positioning of the specified axis.
• Executes teaching of the specified axis.
• Writes parameters/positioning data and block start data to 

a flash ROM.

• Initializes setting data.

Serial communication module

• Sends and receives data to and from an external device.
• Registers and reads user frames.

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.

CC-Link IE network 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 or MELSECNET/H network system.

• Reads and clears error information.
• Sends and receives e-mails.

MELSECNET/H network module

Ethernet interface 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.

Socket communication function

• Opens/closes a connection.
• Reads receive data.
• Changes the receive mode.
