Setting File Registers - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

Setting file registers

This section describes the settings required to use the file registers.
Configuration procedure
This section describes the procedure to use the file registers.
1.
Set the file register usage with [CPU Parameter].
2.
To use the file register for each program, previously create the device memory which will become the file register file.
( GX Works3 Operating Manual)
3.
When using the file registers, which are common for all programs, a file register file with the name and capacity set in the
file register setting is created.
*1 If the capacity is not set, it must be set when creating a file register file and writing it to the programmable controller in the same manner
as the procedure 2.
4.
Write parameters and file register files into the CPU module.
File register setting
This setting must be completed before using the file registers.

Item Description
Use Or Not Setting Specify whether or not file registers should be used.
Capacity Specify the capacity of the file register in increments of 1K
words when "Use Common File Register in All Programs" is
selected.
File name Assign a file name to the file register when "Use Common
File Register in All Programs" is selected.
■Precautions
To access the CPU module from either of the following modules or engineering tools, the size of the file register needs to be
5696K words or less with an extended SRAM cassette (NZ2MC-16MBS) of 16MB.
• C Controller module
• MES interface module
• GOT2000 (when the programmable controller program monitor (R ladder) is used)
• Engineering tool version 1.015R or earlier
• CPU Module Logging Configuration Tool version 1.49B or earlier
• GX LogViewer version 1.49B or earlier
• MX Component version 4.10L or earlier

Setting range
• Not Use
• Use File Register of Each Program
• Use Common File Register in All Programs
This value depends on whether or not the
extended SRAM cassette is mounted and its
capacity. ( Page 96 The setting range of the
