8-4-1 Authentication of User Program Execution IDs
You can set a specific ID (called a user program execution ID) in the CPU Unit in advance. If you do, you
can execute only a user program with the same ID.
You can therefore prevent different CPU Units (hardware) from executing a user program.
In contrast to the protection function, you can still display and edit the user program even if a user pro-
gram execution ID is set.
1 Always backup the project files before you assign a user program execution ID.
2 Assign the user program execution ID to the user program offline from the Sysmac Studio.
Precautions for Correct UsePrecautions for Correct Use
After you assign a user program execution ID to a user program, you cannot change or delete
the ID. To use a different ID, read the project file without an ID that was backed up in step 1,
above, and assign another user program execution ID. To delete the ID, use the project file with-
out an ID that was backed up in step 1, above.
