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

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. ( Page 38 Installing a Battery)
2.
Inserting an extended SRAM cassette or an SD memory card
Insert an extended SRAM cassette or an SD memory card to the CPU module as needed. ( Page 39 Inserting or
Removing an Extended SRAM Cassette, Page 40 Inserting and Removing an SD Memory Card)
Do not power off or reset the CPU module, or remove an SD memory card during an access to the SD memory card. (
Page 162 When an SD memory card is used)
3.
Mounting modules and connecting cables
Mount modules on the base unit and connect cables. ( MELSEC iQ-R Module Configuration Manual,  Page 63 Power
supply modules in a redundant system)
4.
Powering on the control system
Check the following and supply power to the main base unit and extension base units.
• A cable is correctly connected to the power supply.
• The power supply voltage is within the range of the 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 on the main base unit and extension base units: 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 to the CPU module
Start up the engineering tool installed on a personal computer. ( Page 64 Creating a Project)
Connect the personal computer to the CPU module. ( Page 64 Connecting a Personal Computer and the CPU Module)
6.
Initializing the CPU module
Initialize the CPU module using the engineering tool. ( Page 43 Initializing the CPU Module)
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.
