Sanyo 550 instruction manual Close File, Read Data

Page 59

Only ONE file may be opened at a time.

The master should take some special precautions before issuing this command.

Firstly, to ensure that no file activity takes place on the Controller during the file transfer, the master should send a Set Controller to Remote Access Mode command packet (see below). This locks out the keyboard on the Controller.

-Next, the master should use a Status Request command to ascertain the data entry mode of the Controller.

-If the Controller is in Engineering, opening a .CFG file should not be allowed.

-If the Controller is in Program Edit, opening a .PRG file should not be allowed.

-If logging is active, opening a .LOG file should not be allowed.

Only after checking these criteria should the master proceed to Open the file on the Controller for reading. After the file is read and closed, the master should then issue a Set Controller to Local Access Mode command packet to restore the Controller's local keyboard operation.
