Tank Point
A Tank point includes predefined variables specifically designed for tank gauging
applications. The behavior of the tank point is configured via the tank configuration
dialog boxes. A tank variable is any component of the tank such as tank level,
flow, and temperature. Each tank provides process values, or tank variables,
which may be entered manually, received from a field device or internally
calculated. These process variables are listed in the Glossary.
Input Point
Input points are used to receive data from generic field equipment, database
calculations or manual input. Typically these points are used to hold data for
equipment that is not tank specific (i.e. pumps, values or motors). However, they
can also be used to store tank information not covered by the FuelsManager Tank
Point.
Output Point
Output points are used to transmit data from the database to field equipment.
Typically outputs are derived from an operator issuing commands, however, they
can also be derived from an internal calculation process.
Output points may be configured to update the local process value immediately
from the command value or to update the database point value based on inputs
from the field equipment.
Triggered Point
Triggered points are used as an intermediary between points. FuelsManager uses
a triggered point to monitor another point. When it sees a change in the point, the
point gets sent to another point in the database.
Triggered points are typically used to monitor database input from a gauge. Once
the point changes, the triggered point sends it to another point such as an output
point for an OPC server or a PLC.
