'Command execution completed' (X17)
Un\G1000
(Command code/
Command execution
'Command interface
result code)
(CIF)' (Un\G1000 to
Un\G1066)
Area other than
Un\G1000
 Set the transmit message in 'Command interface (CIF)' (Un\G1000 to Un\G1066) via the program.
 Turn on 'Command execution request' (Y17) via the program.
 FFFFH (CIF busy) is stored in Un\G1000 while the command is being processed.
 When the command execution is finished, 'Command execution completed' (X17) turns on.
 Then, 0000H (Completed) is stored in Un\G1000.
The receive message is stored in an area other than Un\G1000 of 'Command interface (CIF)' (Un\G1000 to Un\G1066).
Retrieve the receive message via the program to check the command parameters of the previously executed command.
 After the command (Display current parameter) is completed, turn off 'Command execution request' (Y17) via the program. When 'Command execution
request' (Y17) is turned off, 'Command execution completed' (X17) also turns off.
For the current parameter display, the buffer memory areas are assigned as follows.
