36 PROCEDURE FOR STARTING UP A SYSTEM
USING THE SIL2 PROCESS CPU
This chapter describes the procedures for starting up a system using the SIL2 Process CPU.
36.1 Overview
This section describes the overview of the procedures for starting up a system using the SIL2 Process CPU.
The procedures for starting up both systems at a time are shown in this section.
In the system using the SIL2 Process CPU, both system are started up at a time. However, starting up only
one system is possible when:
• Debugging is required for only one system.
• One system is powered off before module replacement because the system is failed.
When starting up the systems one by one, apply the following procedures but replace the term "both systems"
with "one system" to start up the control system. For start-up of the standby system, refer to the following.

Installing/mounting/inserting procedure
1. Installing batteries
Install a battery to the SIL2 Process CPU of each system. ( MELSEC iQ-R CPU Module User's Manual (Startup))
2. Inserting extended SRAM cassettes and SD memory cards
Insert an extended SRAM cassette or an SD memory card or both to the SIL2 Process CPU of each system 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. (
MELSEC iQ-R CPU Module User's Manual (Application))
3. Mounting modules
Mount each module to base units. ( MELSEC iQ-R Module Configuration Manual)
Wiring procedure
1. Wiring
Wire each module and external device.
