3
Connect the Sysmac Studio online and register the user program execution ID that was set in
step 2 in the CPU Unit.
The registration of the user program execution ID in the CPU Unit is recorded in the event log. At
this time, the user program execution ID in the CPU Unit is overwritten even if it is already regis-
tered.
4
Transfer the user program with the same user program execution ID to the CPU Unit.
If the user program execution ID in the user program does not match the user program execu-
tion ID in the CPU Unit or if one of them does not have an ID, an ID Verification Error (major fault
level Controller error) occurs when you attempt to change to RUN mode and the CPU Unit will
not operate.
After you assign a user program execution ID to the CPU Unit, you cannot read or delete the ID.
To delete the ID from the CPU Unit, perform the Clear All Memory operation on the CPU Unit.
Operation When an ID Verification Error Occurs
When the User Program Execution ID in the CPU Unit Is Incorrect or Not
Registered:
Connect online to the CPU Unit from the Sysmac Studio and perform the following steps.
1
Overwrite or register the correct user program execution ID in the CPU Unit.
2
Cycle the power supply to the Controller, or reset the CPU Unit from the Sysmac Studio.
When the User Program Execution ID Is Not Assigned to the User Program or
Is Incorrect
1
Read the backed up project file from the Sysmac Studio, and assign the correct user program
execution ID.
2
Connect the Sysmac Studio to the CPU Unit online and transfer the user program.
3
Cycle the power supply to the Controller, or reset the Controller from the Sysmac Studio.
Other Situations
To Delete the User Program Execution ID Assigned to the User Program:
Read the backed up project file in the Sysmac Studio.
To Delete the User Program Execution ID from the CPU Unit:
Connect the Sysmac Studio to the CPU Unit online and perform the Clear All Memory operation.
To Check the User Program Execution ID Assigned to the User Program:
For security, the user program execution ID that is assigned to the user program cannot be checked
from the Sysmac Studio. Read the backed up project file in the Sysmac Studio and set the user pro-
gram execution ID again.
