Starting Up The Systems One By One - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

14.
Monitoring the Program
Check that the program is normally running on the engineering tool. ( Page 434 Monitoring the Program)

Starting up the systems one by one

To debug a program with only one system before operation, start up the control system.
To start up the control system for a purpose other than debugging a program, start up the standby system to build a redundant
system.
Starting up the control system
Start up only the control system.
1.
Installing a battery
Install a battery to the CPU module. ( MELSEC iQ-R CPU Module User's Manual (Startup))
2.
Mounting an extended SRAM cassette and inserting an SD memory card
Mount an extended SRAM cassette and insert an SD memory card to the CPU module as needed. ( MELSEC iQ-R CPU
Module User's Manual (Startup))
Do not power off or reset the CPU module, or remove an SD memory card during an access to the SD memory card. (
Page 411 Using an SD memory card)
3.
Mounting modules and wiring each device
Mount modules on the base unit and wire each device. ( MELSEC iQ-R Module Configuration Manual,  Page 429
Wiring to the power supply modules in a redundant system)
4.
Powering on the system
Check the system for the following and power on the system.
• Wiring to the power supply module is correct.
• The power supply voltage is within the range of specifications.
• The CPU module is in the STOP state.
Check that the following LEDs turn on after the system is powered on.
• Power supply module: POWER LED
• CPU module: READY LED
• Redundant function module: RUN LED
In step 4, the ERROR LED of the CPU module flashes and the ERR LED of the redundant function module turns on. Proceed
to the next step.
5.
Connecting a personal computer and the CPU module
Start an engineering tool installed on a personal computer. ( Page 430 Creating a Project)
Connect the personal computer on which the engineering tool has been installed and the CPU module. ( Page 430
Connecting a Personal Computer and a CPU Module)
6.
Initializing the CPU module
Initialize the CPU module with the engineering tool. ( MELSEC iQ-R CPU Module User's Manual (Startup))
7.
Setting parameters
Set system parameters, CPU parameters, and module parameters. ( MELSEC iQ-R CPU Module User's Manual
(Startup))
• To use the functions that require an SD memory card, set memory card parameters.
• To mount an intelligent function module, set intelligent function module parameters.
Users can set system parameters by reading the actual system configuration to the module configuration 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. (
