7.
Setting parameters
Set system parameters, CPU parameters, and module parameters. ( Page 43 Setting Parameters)
• To execute the functions that access the SD memory card, set memory card parameters.
• When an intelligent function module is used in the system, set intelligent function module parameters.
Users can set system parameters by loading the actual system configuration to the "Module Configuration"
window of the engineering tool.
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 program to the CPU modules of both systems using the engineering tool. ( Page 67
Writing Data to the Programmable Controller)
11.
Resetting the CPU modules
Restart both systems in either of the following ways.
• Powering off and on the system
• Resetting the CPU module
12.
Checking the LEDs
Check that the LEDs of each CPU module and redundant function module are in the following states. The CARD READY LED
status (on or off) depends on whether an SD memory card is inserted to the CPU module or not.
• LEDs of system A
If an error has been detected, the following LEDs turn on. Identify the error using the engineering tool, and eliminate the error
cause.
• CPU module: ERROR LED ( Page 533 LED status of the CPU module)
• Redundant function module: ERR LED, L ERR LED ( Page 537 When the ERR LED turns on or flashes,  Page
537 When the L ERR LED turns on)
To start up the system when the data logging function is used, refer to the following.
