Operation
Stopping remote I/O communi-
cations with all Slaves
Stop communications with the use of the CX-Inte-
grator or
*_Sw1IOCommStopCmd
(Remote I/O
Communications Stop Switch).
Using a scan list in remote I/O
communications (fixed alloca-
tions)
Change
*_Sw1SListEnblCmd
(Scan List Enable
Switch) to TRUE.
Enabling a scan list in remote I/O
communications (user-set allo-
cations by device variables for
CJ-series Unit)
Set the allocation areas with the use of the device
variables for CJ-series Unit, and change
*_Sw1MstrAlocCmd
(Master User-set Allocations
Switch) to TRUE.
Changing the communications
system configuration
Change
*_Sw1SListClrCmd
(Scan List Clear
Switch) to TRUE, and change
*_Sw1SListEnblCmd
(Scan List Enable Switch) to
TRUE after you change the communications sys-
tem.
Checking master I/O allocations
status (fixed allocations, user-set
allocations by device variables
for CJ-series Unit, user-set allo-
cations with the CX-Integrator)
Monitor the Master Status 2 status codes in
*_Mstr2Sta
from Sysmac Studio.
Checking to see if all slaves are
registered in the scan list
Check
*_RegSlavTblSta
(Registered Slave Table).
3-2-11 Regis-
tered Slave
Table
Checking to see if all slaves are
performing remote I/O communi-
cations properly
Check
*_NormSlavTblSta
(Normal Slave Table).
Checking to see if there is an
error history in the DeviceNet
Unit
Check the error history (registration yes/no) from
Sysmac Studio.
Monitoring the error history in
the DeviceNet Unit
Execute the device monitor function from the CX-
Integrator (Error History Tab).

OPERATION
MANUAL
(W464)
Monitoring status of the
DeviceNet Unit
Execute the device monitor function from the CX-
Integrator (Status and Unit Status Tabs).
Checking the current communi-
cations cycle time
Execute the device monitor function from the CX-
Integrator (Current Communications Cycle Time
Tab).
Adjusting the communications
cycle time
Execute the device parameter edit function from
the CX-Integrator (Communications Cycle Time
Tab).
Saving all parameters, like scan
list data, for masters and slaves
on the network
Save the network configuration from the CX-Inte-
grator.
Replacing a DeviceNet Unit
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
change
*_Sw1SListEnblCmd
(Scan List Clear
Switch) in the device variables for CJ-series
Unit to TRUE.
