Appendix 5 Setting The Parameter With A Program; Procedure; Program Example - Mitsubishi Electric MELSEC iQ-R Series User Manual

Appendix 5
This section describes how to set the parameter with a program without using an engineering tool when the MELSEC-Q
series project is used.

Procedure

1.
Set the parameter setting method to "Program" in the module parameter of the engineering tool.
[Module Parameter]  [Basic Setting]  [Parameter Setting Method]  [Basic parameter setting]
2.
Create a program for setting the parameter or starting the I/O communication start with the engineering tool.
3.
Write the set parameter and created program to the CPU module, and reset or power off and on the system.
[Online]  [Write to PLC]
When the parameter is set with the program, the I/O communication does not start automatically. Therefore, start the I/O
communication with 'I/O communication request' (Y11) or 'Auto communication start setting' (Un\G1585).

Program example

The following programs of the master node are divided. Write the divided programs as one program to the CPU module.
Page 97 Setting the parameter for master function
Page 102 Setting the master/slave function common parameter
Page 105 Saving the parameter of the master node
The following programs of the slave node are divided. Write the divided programs as one program to the CPU module.

Setting the parameter for master function
Set the parameter to the RJ71DN91 master node without using the engineering tool or auto configuration tool.
