12.2 Registering Transparent Codes and Additional Codes
To control transparent codes and additional codes for data to be sent/received with the non procedure or bidirectional
protocol, it is necessary to perform settings in the Q series C24 prior to data communication.
The following explains the registration of transparent and additional codes.
(1) For each interface, 10 combinations and one combination of transparent
codes and additional codes can be set for transmission and reception,
respectively.
(2) Transparent and additional codes are registered on the GX Configurator-SC's
"Transmission control and others system setting" screen.
If additional data code is received during data reception, the Q series C24 will not treat the immediately succeeding one-byte
data as the following control data:
● Data received as the first frame and last frame of the user frames
Therefore, do not set the following:
(The code of the data described above cannot be designated as additional codes for data reception.)
• A receive user frame that contains additional code data for data reception
• The same reception complete code as the additional code data for data reception
