8.
Creating a program
Create a program with the engineering tool. After creating the program, convert the program and save the project. ( Page
46 Programming)
9.
Writing the system A/B setting
Set the system A or B using the engineering tool. ( Page 65 Setting the System (System A or System B))
10.
Writing data to the programmable controller
Write the set parameters and created programs to the CPU module using the engineering tool. ( Page 67 Writing Data to
the Programmable Controller)
11.
Resetting the CPU module
Restart the control system in either of the following ways.
• Powering off and on the system
• Resetting the CPU module
12.
Starting up the system (in a redundant system without extension base units)
Perform the following operation using the engineering tool to start up the system as the control system within the time set in
"Other system Start-up Timeout Setting".
[Online]  [Redundant PLC Operation]  [Redundant Operation]
Select "Forced Start of Control System while Waiting for Other System to Start" and click the [Execute] button. (When "Other
system Start-up Timeout Setting" of "CPU Parameter" has not been changed, a stop error occurs in 60 seconds.)
Check that the CTRL LED of the redundant function module turns on.
When the CPU parameters have been set, users can start up only one system with the following operations.
( Page 425 Redundant System Operation Setting)
• Switch operation: Set the RUN/STOP/RESET switch of the CPU module to RUN  STOP  RUN.
• Input (X) operation: Turn on the input (X) set in the parameters.
13.
Starting up the system (in a redundant system with redundant extension base unit)
The system starts up as the control system. (The system does not wait for the other system to start and starts up as the
control system.)
• If the RUN/STOP/RESET switch is set to the RUN position, the CPU module enters to the RUN state while
the standby system does not start. To start control of the redundant system when both systems have started
up, start up the control system with the RUN/STOP/RESET switch set to the STOP position.
• The CPU module does not start up if the extension cables between extension base units are incorrectly
connected. Ensure that the cables are correctly connected.
