4-1-3 Offline Operations

The following operations are possible when not connected online to the PC.

Group Name Description

Programming Connect line Draws a line between two ladder diagram objects.

Save program Writes all or part of the user program developed in the system work area to the

data disk.

Retrieve program Retrieves all or part of the user program stored on a data disk to the system

work area.

Change display Specifies the display modes for the user program.

Search Searches for instructions including specified operands. An address from which

the search is to be started can be specified

I/O comment Creates I/O comments corresponding to bit addresses in the Ladder With

Comments mode. In addition, reads (searches) and edits the program for

comments.

Instr comment Creates and edits instruction comments for output instructions in the Ladder

With Comments mode. (C-series PCs only)

Block comment Creates, reads (searches), and edits block comment in the Ladder With

Comments mode.

Edit ladder Edits ladder diagrams using the following:

•Moving specified instruction blocks

•Copying specified instruction blocks

•Deleting specified instruction blocks

Edit comments Displays I/O comments simultaneously to write, edit, and search for specified

comments.

Retrieve

comments Retrieves comments from the program stored on a data disk. The I/O comments

are read to the system work area. Instruction comments (C-series PCs only)

and block comments are copied to the currently displayed program.

Memory usage Displays the used capacity of the user program memory, the number of

comments used, and the available capacity of the internal memory.

Clear memory Clears the user program memory. The starting address for clearing can be

specified. The comment memory can also be cleared.

Check program Checks whether the user program contains syntax errors. The check can be

performed in three levels.
