Copy Function
Use the following procedure to execute the copy function.
1,2,3...
1.
Send the COPY command.
2.
After receiving the response, wait for processing to be completed (approx.
10 s per Temperature Controller).
3.
Read the status to confirm that the copy function is stopped. If bit 1 of the
leftmost byte is ON, the copy function is still being executed. If it is OFF, the
copy function is stopped.
4.
Read the status again and confirm the results (rightmost byte). The mean-
ing of each bit of the rightmost byte is as follows:
Bit 0: ON for a normal end. (OFF for an error end or when the copy func-
tion has not been executed.)
Bit 1: OFF
Bit 2: ON if a communications error occurred when starting the upload or
download.
Bit 3: ON if an EEPROM hardware error or checksum error occurred when
starting the upload or download.
Bit 4: ON if a communications error occurred when executing the upload
or download.
Bit 5: ON if there was no backup data to download.
Bit 6: ON if the backup data configuration does not match the actual con-
figuration for an upload or download.
Bit 7: OFF
