Response information
1. Set the command code of the RESET command in 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. If the Reader/Writer can be reset, it sets the response code and turns ON the
NORM signal.
4. When the PLC detects that the NORM signal is ON, it turns OFF the EXE signal. This tells the Reader/
Writer to stop execution.
5. When the Reader/Writer receives the instruction to stop execution, it resets itself. After the Reader/Writer
restarts and the cyclic data exchanges connections are established again, the Reader/Writer turns ON the
READY signal and turns OFF the BUSY signal and NORM signal.
