Station
The main operator interface to PlantScape. Station can run on either a remote computer
through a serial or LAN link, or the server computer.
When Station is running on the server computer, it is often referred to as a server
Station. When it is running on a machine other than the server, it is often referred to as
an operator Station.
Station Automation object model
The Station Automation object model provides the programming interface through
which scripts control Station and its displays.
status point
A point type used to represent discrete or digital field values. The point can have input,
output, and mode values. Input values can represent eight discrete states and cannot be
changed by an operator. Up to three values can be read from up to three consecutive,
discrete locations in the controller and thus can represent up to 8 states.
Output values can be used to control up to two consecutive discrete locations in a
controller. Output values can be automatic or operator-defined.
Mode values apply to output values and determine whether or not the output value is
operator-defined or automatic.
supervisory control
The action of writing information to a controller. PlantScape enables both automatic and
manual supervisory control. See Mode.
task
A task is any of the standard server programs or an application program that can be
invoked from a display.
TCP/IP
‘Transmission Control Protocol’/‘Internet Protocol’. A standard network protocol.
TDC 3000
Total Distributed Control 3000 (Honeywell’s Digital Control System.)
terminal server
A device on the local area network (LAN) that connects to a controller by way of a serial
connection and enables the controller to “talk to” the PlantScape server on the LAN.
