Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual page 54

Device station parameter automatic setting is executed under the following conditions.
• The device station is a CC-Link IE TSN module. (For checking if a module is compatible with automatic
update of saved parameter, refer to the manual of the module being used for the device station.)
Setting method
Set in the "Parameter of Device Station" window. (Page 113 Parameter processing of a device station)
Precautions
• A device station whose device station parameter automatic setting abnormally ended does not start data link, and
'Execution result of device station parameter automatic setting function' (SW0160 to SW0167) turns on. Check 'Detailed
execution result of device station parameter automatic setting' (SW0194) and the event history and perform corrective
actions according to Action of the error codes list.
• Do not disconnect the device station that is currently executing an automatic update of saved parameters. Update of
parameter may fail.
• Do not turn off the master station that is currently executing an automatic update of saved parameters. Incorrect
parameters are automatically set in the device station at the next power-on.
• If saved parameters are not in the CPU module when executing an automatic update of saved parameters, device station
parameters are newly generated.
• Check if the checkbox of "Parameter Automatic Setting" of the device station is selected in "Network Configuration
Settings" under "Basic Settings".
• Check if the IP address of the device station in the "Network Configuration settings" under "Basic Settings" matches the
actual IP address of the device station.
• When the communication speed differs between the master station and the station for which the device station parameter
automatic setting is performed, the device station parameter automatic setting may end abnormally. When the setting ends
abnormally, check that their communication speeds match.
• When the parameters of a device station are stored in the SD memory card, "Memory Card Parameter"  "Setting of File/
Data Use or Not in Memory Card"  "Parameter of Device Station" for the CPU module is set to "Use" to write the memory
card parameters and device station settings to the SD memory card.
• There is a limit to the number of device station parameter files that can be saved with the CPU module.
For details, refer to the following.
MELSEC iQ-F FX5 User's Manual (Application)
When using MR-J5(W)-G and executing device station parameter change (write back), the servo parameter
"Parameter automatic backup update interval (PN20)" must be set. When the stored parameters are different
between the CPU module and the device station for each setting time, the parameters are written back by
setting this parameter. For reflecting changed parameters on the project, Take the following procedure.
• Device station parameter window  "Read"  Read parameters from servo amplifiers directly  Apply the
device station parameter to the project
The number of writes to the data memory of CPU module is limited. For details, refer to the following manual.
