1. The command code, command parameters, and command data are set from the PLC while the READY
signal is ON.
2. The user (PLC) turns ON the EXE signal. This tells the Reader/Writer to start execution.
3. When the Reader/Writer receives the instruction to start execution, it turns OFF the READY signal and
turns ON the BUSY signal.
4. When communications end normally, the Reader/Writer sets the response code and response data and
turns ON the NORM signal.
5. The user (PLC) detects that the NORM signal has turned ON and reads the response data. After reading
the data, the user (PLC) turns OFF the EXE signal. This tells the Reader/Writer to stop execution.
6. When the Reader/Writer receives the instruction to stop execution, it turns ON the READY signal and turns
OFF the BUSY signal and the ERR signal.
7. When communications end in an error, the Reader/Writer sets the response code and response information
and turns ON the ERR signal.
8. The user (PLC) detects that the ERR signal has turned ON, reads the response code and response
