Application Programming Interface

AW/WSTA

Application Workstation / Workstation

Backtrack / BKT

A snapshot in time of the simulator process model and Foxboro controls, historian, and alarms. By default snapshots are taken every 60 seconds.

CAD

Current Alarm Display

Control database

I/A Series®/Control Core Services control system database processed by the control software. This database consists of compounds and blocks configured using the I/A Series / Control Core Services control system database Configurator. Example: ICC, IACC, FCS, Foxboro Evo

Checkpoint File

The control database that resides on the host workstation, which is downloaded to the FCP270 / ZCP270 or SCP.

Configurator

ICC / IACC / FCS / Foxboro Evo

CP

Control Processor. The Control Processor performs any mix of integrated first-level automation functions such as continuous, sequential, or discreet logic functions.

CP Host

The AW/WSTA configured with Foxboro System Definition software that hosts the CP configuration. This computer differs from the machine running the SCP software.

DEW

Data Entry Window

DSS

Dynamic Simulation Suite (Infrastructure for the simulator)

ECB

Equipment Control Block

Elapsed Simulation Time

See Simulation Time, Elapsed

FAIM Engine

Simulation engine for Foxboro AIM*

FBM

Fieldbus Module

FCP

Field Control Processor

FCS

Foxboro Control Software is an InFusion replacement

FECN

Foxboro Evo Control Network (formerly known as MESH network).  The network between every machine with Foxboro Evo software installed.

GUI

Graphical User Interface

HMI

Human Machine Interface

I/A Series

Intelligent Automation Series

IACC

I/A Series Configuration Component

IC

Initial Condition. A snapshot in time of the simulator process model, Foxboro controls, historian, and alarms.

ICC

Integrated Control Configurator

I/O

Input/Output. The physical communication to and from the Control System and or plant operation actuators.

MESH

The network between every I/A Series/Control Core Services software installed machine.  Now called the Foxboro Evo Control Network (FECN).

OM

Object Manager

OTS

Operator Training Simulator

PAS

Process Automation System. Equivalent to Distributed Control System (DCS)

S4M

SIM4ME extension that displays on the compressed simulation file

SaveAll

ICC Driver Task (iccdrvr) command used to save controls from the ICC via an API call

SCP

Simulated CP270 / CP280

SimSync Engine

A DSS engine to manage time for simulation

Simulation Executive

The SimExec controls time, synchronizes engines, and sends data between engines in a simulator

Simulation Time, Elapsed

This is the amount of time the simulation has run since the simulation was started or since a snapshot was restored. The DYNSIM GUI displays the elapsed simulation time and the DYNSIM Snapshot Summary table stores the elapsed simulation time with each IC.

Running faster than real time (simulation speed > 100%) will result in the elapsed simulation time being greater than elapsed wall clock time.

Running slower than real time (simulation speed < 100%) will result in the elapsed simulation time being less than elapsed wall clock time.

Simulation Time, Skewed

The skewed simulation time differs from computer system time when the simulation is run either faster or slower than real time. In order to preserve the proper slope on a trend when running faster or slower than real time, the time must progress faster or slower than normal and thus is skewed.

This can create a situation in which the time displayed on a trend or alarm is "in the future" or "in the past" with respect to the computer system time.

Simulation Time Control

The ability to freeze or run the simulation and to save and restore snapshots to jump the simulation to a different condition.
