variables for CJ-series Unit, and change
*_Sw1MstrAlocCmd (Master User-set Allocations
Switch) to TRUE.
Change *_Sw1SListClrCmd (Scan List Clear
Switch) to TRUE, and change
*_Sw1SListEnblCmd (Scan List Enable Switch) to
TRUE after you change the communications sys-
tem.
Monitor the Master Status 2 status codes in
*_Mstr2Sta from Sysmac Studio.
Check *_RegSlavTblSta (Registered Slave Table).
Check *_NormSlavTblSta (Normal Slave Table).
Check the error history (registration yes/no) from
Sysmac Studio.
Execute the device monitor function from the CX-
Integrator (Error History Tab).
Execute the device monitor function from the CX-
Integrator (Status and Unit Status Tabs).
Execute the device monitor function from the CX-
Integrator (Current Communications Cycle Time
Tab).
Execute the device parameter edit function from
the CX-Integrator (Communications Cycle Time
Tab).
Save the network configuration from the CX-Inte-
grator.
1. Insert a SD Memory Card in the CPU Unit and
change the Unit Setup File Backup Switch in
the device variables for CJ-series Unit to
TRUE.
2. Replace the DeviceNet Unit.
3. Change Sw2FileRestoreCmd (Unit Setup File
Restore Switch) to TRUE.
4. Change *_Sw1SListEnblCmd (Scan List
Enable Switch) in the device variables for CJ-
series Unit to TRUE.
5. Make sure the slave is connected, and then
