n+8
01
Loop 1 AL1 Flag
The AL1/AL2 Flag is ON when the temperature is within the alarm
range set for the input value. The flag is OFF when the tempera-
ture is not within the alarm range set for the input value.

Loop 2 Save Com-
pleted Flag
The Save Completed Flag turns ON when writing data from RAM
to EEPROM has been completed. The write is started by turning
ON bit 14 of CIO (n+2), the Save Bit. The Save Completed Flag
turns OFF when the Save Bit turns ON. (It is OFF immediately
after power is turned ON.)
14
Sensor Error
Flag
The Sensor Error Flag turns ON for the following:
A sensor is not connected.
The connection to sensor is broken.
A temperature exceeding the specified temperature range has
been input.
13
CT Overflow
Flag
The CT Overflow Flag turns ON if the heater current detected by
the CT (Current Transformer) exceeds 55.0 A.
12
Fatal Control
Error Flag
The Fatal Control Error Flag turns ON for the following:
Cold-junction compensator error, CPU Unit WDT error
11
Standby Flag
The Standby Flag turns ON when the Temperature Control Unit is
waiting for I/O refreshing after power is turned ON or the Unit is
restarted.
10
PID Con-
stants Calcu-
lated Flag
The PID Constants Calculated Flag turns ON when the PID con-
stants calculated for autotuning have been updated.
When this flag is ON, the PID constants in the Operating Parame-
ters Output Area have not been output to the Temperature Control
Unit. When this flag is OFF, the PID constants in the Operating
Parameters Output Area have been output to the Temperature
Control Unit.
09
Setting Error
Flag
The Setting Error Flag turns ON when there is a setting error in the
settings in the I/O memory of the CPU Unit.
08
Stop Flag
When the Stop Flag is OFF, the Temperature Control Unit is con-
trolling temperature. When it is ON, the Temperature Control Unit
is not controller temperature.
05 to 07

Leave set to all zeros.
04
Control Out-
put Flag
The Control Output Flag is ON when the control output is ON.
03
AT Flag
The AT Flag is ON when autotuning is being performed. The AT
Flag is OFF when autotuning is not being performed.
02
HB Flag
The HB (heater burnout) Flag turns ON if the detected heater cur-
rent reaches or exceeds the value set as the Heater Burnout Cur-
rent.
01
AL1 Flag
The AL1/AL2 Flag is ON when the temperature is within the alarm
range set for the input value. The flag is OFF when the tempera-
ture is not within the alarm range set for the input value.
