10 Parameter save (Recorder
→
SD)
The current parameter and system state is saved to an SD card.
The result of save of parameter can get by reading the same address "006F". (Status response value)
(A file name is "modprm.dps" fixation. Keep the file of a same name from existing on an SD card.
Moreover, it becomes an error if a file already exists.
Please save after deleting a file previously.)
●
The check on a Modbus protocol
①
Data receive only "0000H" or "AA01H". (The other command becomes a command error.)
②
When data is "0000H", "0000H" is set as a status response value.(Save of parameter is not
started.)
③
Save the parameter when data is "AA01H", and the following conditions are satisfied.
・
The last status response value of parameter read = 0000H
・
The last status response value of parameter write = 0000H
・
The SD card is inserted.
Save of parameter is started. A status response value becomes "5500H".
●
The status response after a save of parameter.
A status response is as follows.
5500H = Now writing
5501H = Writing success
5510H = A file already exists.
5511H = File writing error
0000H = "Write of parameter" preparation completion
※
In order to check completion of action, please wait until a status response becomes except for
"5500H" or "0000H".
