Input Points - Process Data
DESCRIPTION - POINT DESCRIPTION
This process variable is the name by which the input point is known to the user. This variable is entered when
configuring the input point, but cannot be modified via Operate
PROCESS VALUE - PROCESS VARIABLE OR SETPOINT
This process variable is the current value of the input point. This variable is usually linked to automatic tank
gauging systems, PLC's or DCS systems, but can also be manually entered by the operator
ALARM STATUS - COMPOSITE ALARM STATUS
This variable is a composite value that displays a coded variable representing the highest priority alarm for the
input point. Possible values depend on the format of the alarm definition associated with the input point.
FuelsManager calculates this alarm based on the current process value and the alarm definition configured for
the input point. This variable can be viewed from the Operate interface but cannot be modified
UNITS - ENGINEERING UNITS
This variable is the engineering units of the input point's process variable. This variable is entered when
configuring the input point, but cannot be modified via Operate
TIME - TIME OF LAST VALUE UPDATE
This process variable is the last time that the input point's process value was updated. This variable can be
viewed from the Operate interface but cannot be modified
TICKS - MILLISECONDS OF LAST UPDATE
This process variable is the number of milliseconds that have elapsed since input point's process value was
updated. This variable can be viewed from the Operate interface but cannot be modified
MAXIMUM - MAXIMUM SCALING VALUE
This variable is the maximum range for the input point's process value. This variable is entered when configuring
the input point, but cannot be modified via Operate
MINIMUM - MINIMUM SCALING VALUE
This variable is the minimum range for the input point's process value. This variable is entered when configuring
the input point, but cannot be modified via Operate
