Introduction to SCP Software

SCP software performs the functions available in Field Control Processor 270 / 280 (FCP270 / FCP280, Z-Module Control Processor 270 (ZCP270), and Field Device Controller 280 (FDC280) in an off-line system for control logic verification, Human-Machine Interface (HMI) familiarization, and operator training.

The control system configuration from the plant loads directly into the SCP application running FCP/ZCP stations, using the same procedures used to download a configuration to an actual CP. This occurs regardless of whether using the Integrated Control Configurator (ICC), I/A Series Configuration Component (IACC), or Foxboro Evo.

SCP optionally connects to the DYNSIM Dynamic Simulation Suite (DSS) infrastructure for simple-tieback or process modeling capabilities. This DSS infrastructure and a "lite" modeling engine, DYNSIM-L, is provided and licensed with SCP. DYNSIM software features operator training and engineering analysis capabilities as standard, such as Freeze/Run, and Save/Restore of snapshots. Additional library sets or other simulator engines can be included to extend the simulator for high-fidelity simulator training and optimization.

SCP software runs with a variety of configuration:

• Standalone, in which the SCP instances run in real time, just like real CPs (no DSS infrastructure required)

• As an engine to a tieback or Operator Training Simulator (OTS), where the DSS infrastructure is installed and all Foxboro Evo computers include DSS software to control time in trends, graphics, and alarms

• On a single computer for small controls-checkout projects, where it can support up to 25 CPs per computer, with or without the DSS infrastructure

• On multiple computers, for large projects that require more than 25 CPs (in which a multi-computer configuration with two or more SCP computers is designed to replicate the actual plant HMI and configuration), with or without the DSS infrastructure.

The Operator or Engineering Workstation computer (AW/WSTA) provides the primary operator interface to the control system emulation for configuration, monitoring, and interaction with the controls, while the SCP computer provides the interface to the control emulation and the process model. The figure below displays a typical simulator configuration for a Foxboro Evo system.

Typical configuration for a Foxboro Evo System

The SCP computer executes the SCP Engine on either Windows 7 64-bit (Professional or Enterprise), Windows Server 2008 R2 64-bit (Standard), Windows 10 (Professional or Enterprise) or Windows Server 2016.

Note: Multi-core and multi-threading must be enabled on the SCP computer.

The DSS environment, or Instructor Station, can reside on several Windows Operating System (OS) environments. Review the SCP Installation Guide and DYNSIM Release Notes for specific supported OS details. In a multi-computer configuration, the host WSTA is connected to the SCP. CPs deploy through the control configurator (ICC/IACC/Foxboro Evo IDE). The control configurator (or WSTA) provides the primary operator interface to the control system emulation for configuration, monitoring, and interaction with the controls. The CPs within the SCP computer communicate with each other through Foxboro Evo Control Core Services software.
