8.2 Procedures for replacing when file registers are used in blocks

This section explains the procedures for using existing data in the file registers used in more than one

block in the ACPU.

8.2.1 When block switch command is used

Solution and Benefit

File registers can be replaced only by modifying commands and using the existing data.

(1) Procedures for using existing ACPU projects

‥

When‥file‥registers‥in‥more‥than‥one‥block‥are‥used‥in‥ACPU,‥it‥is‥necessary‥to‥save‥the‥projects‥

with different names for the blocks.

Step 1: Retrieve the program, parameters and device comment data from ACPU using GX

Developer. Retrieve the data to the PC with the specified file register block number, and

save the data as a project.

Step 2: Retrieve the data in another specified file register block number to the PC, and save the

data with a project name different from that used in Step 1.

Step 3: Change the type of the ACPU project file saved in Step 1 to QCPU/LCPU by "Change PLC

type."

Step 4: Open the ACPU project file saved in Step 1, and display the device memory R. Open the

QCPU/LCPU project file which has been changed in the PLC type in Step 3, and display

the device memory ZR.

Step 5: Drag the mouse in the device memory R of ACPU to copy all range, and paste it from the

beginning of each block in the device memory ZR of QCPU/LCPU.

For the beginning of each block, see "Tip."

Step 6: Open each project saved in Step 2, copy all range of the file register R, and paste it from

the beginning of each block in the device memory ZR of the QCPU/LCPU project created

in Step 4.
