WARNING
Do not change the Value, Offset/Polarity, Exp:Num, I/O
Type, Sensor/Actuator Type, Min/Max, or Resolution I/O
configuration parameter for the points listed below. Changing
these parameters could cause improper control and/or equip-
ment damage.
Use extreme caution if locking a point as this may also cause
improper control and/or equipment damage.
