Inputs
(Tempera-
ture Con-
trol Unit to
CPU Unit) n+19 15 Loop 4 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+12), the Save Bit. The Save Com-
pleted 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 --- Leave set to 0.
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
constants calculated for autotuning have been updated.
When this flag is ON, the PID constants in the Operating
Parameters Output Area have not been output to the Tempera-
ture 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
controlling 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 --- Leave set to 0.
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
temperature is not within the alarm range set for the input value.
