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.
