(1) The bit associated with the alert detected on the corresponding channel turns to
"1".
When the cause of the detected alert is removed, the corresponding bit turns to
"0".

(2) When each alert detects errors during control, the control is continued. Output
does not turn OFF.
(1) Stores the Q62HLC-detected value on which the following processings have
been performed:
• Linearization
• Sensor compensation
(2) This flag checks whether the measured value (PV) is within approach band.
(3) This flag turns to "1" when the measured value (PV) is within approach band.
Setting the soak time criteria (buffer memory address:168) will cause this flag to
turn to "1" when the measured value remains within approach band for the set
time.
(1) The result of PID operations, which are performed based on the measured
value, is stored.
(2) The value stored is in the range -50 to 1050 (-5.0% to 105.0%).
(3) The manipulated value is % to full-scale (16mA) of output range (4 to 20mA).
0% outputs 4mA, 50% outputs 12mA and 100% outputs 20 mA.
