This chapter explains the binary-to-ASCII conversion (called ASCII-BIN conversion) in
order to send/receive data in ASCII format to/from an external device.
ASCII-BIN conversion is a data conversion function that converts all data
communicated between the Q series C24 and an external device to ASCII code data.
The ASCII-BIN conversion of communication data is performed by the Q series C24
according to the user settings.

In order to convert data to be sent/received via the non procedure protocol and
bidirectional protocol from binary code to ASCII code, it is necessary to make specific
settings for the Q series C24 before performing data communication.
The following describes the settings for the ASCII-BIN conversion:
(1) The ASCII-BIN conversion settings can be designated for each interface.
(2) The ASCII-BIN conversion settings are registered in the "Transmission control and
others system setting" screen of GX Configurator-SC.
