1. When I0000 is ON and the analog input status error for the analog I/O cartridge is 5, 6, or 8 to 11, M0020 turns ON.
When the analog output status error for the analog I/O cartridge is 8 to 11, M0021 turns ON.
2. The PID instruction operates when I0000 is ON and both M0020 and M0021 are OFF.
The operating status of the PID instruction is judged, and when an error occurs, M0022 turns ON.
3. When M0020 or M0021 is ON, or when I0000 is OFF (when the PID instruction is stopped), 0 is stored in D8186 and 0 V
is output from AQ4.
4. The operating status of the PID instruction is judged, and when an error occurs, M0021 turns ON.
5.
When either M0020, M0021, M0022, or M0003 (Alarm 1 output (process high alarm)) is ON, Q0001 (alarm lamp) turns ON.
