(1) The data codes used while communicating are listed below.
1) Ethernet module External device
Data can be communicated by selecting either binary code or ASCII code
in the data code setting of FX Configurator-EN or the PLC, as shown
below.
For more details about binary code/ASCII code changeover, refer to
Section 4.6, "Communication Settings".
: Selectable : Cannot be communicated
*1 Communication is performed in binary code regardless of the communication code setting.
NOTE
When sending/receiving e-mail, communication is performed using the data code
handled by each function, regardless of the setting of the communication data code.
