PAC8000 Workbench Getting Started Guide
DesignerSim
– Enables the control system designer to test control strategies in a single
controller without the need of physical hardware.
Discrete Control
– The IEC 61131-3 programming environment.
Dynamic Link Libraries (dll)
– Programming unit that provides functions or information
to other programs.
Ethernet
BIM
– Controller type that functions as a remote IO scanner, as no control
strategies are supported.
Executable File (exe)
– File that can run directly on a computer.
Floating Point
– IEEE precision numbers that are represented in two consecutive
registers.
Function Block
– Unit of code that uses inputs to compute one or more output(s).
Examples of function blocks include PID and motor control.
HART
– Communication protocol that places digital information on top of a 4-20mA
signal, allowing a transmitter to send up to four data values in addition to the normal 4-
20mA signal.
Human Machine Interface (HMI)
– Graphical view of the process normally presented to
the operator, consisting of items such as value displays, animation, and trends.
Hybrid Controller
– Controller type that supports both Process (Advanced Function
Blocks, such as PID and Motor Control) and Logic (IEC 61131-3) control strategies.
Hybrid Workbench
– Licensed version of the workbench that supports creating control
strategies in both Process (Advanced Function Blocks, such as PID and Motor Control)
and Logic (IEC 61131-3) languages.
Hysteresis
– Prevents alarms from recurring when the value is hovering close to the set
point.
IEC 61131-3
– International standard that defines how certain programming languages
and their attributes should behave.
IEC languages
– Ladder Diagram, Structured Text, Instruction List, Function Block
Diagram, and Sequential Function Chart.
InBatch
– Invensys’s S88 compliant batch execution engine.
Industrial SQL Server
– Invensys’s historian.
Integer
– Number that can be represented in a single register.
