EcoStruxure Foxboro SCADA SCD2200

Overview

The EcoStruxure Foxboro SCD2200 is an Intelligent Station Computing Device capable of performing a full range of control and data acquisition functions in all industrial remote SCADA applications. The SCD2200 is designed to operate remotely in harsh environments and can be easily configured for SCADA applications such as:

• Oil and gas production including offshore platforms
• Well monitoring, wet gas, and high level well control applications
• Oil and gas transportation facilities including pipelines
• Water and wastewater treatment plants
• Water and heating distribution networks

The SCD2200 supports several modular plug-and-play options, including low-density or high-density I/O modules, redundant CPU, redundant power supplies, power-integrated backplanes, communication lines, and interfaces to typical communications media. It utilizes optimized transmission techniques for low speed data lines.

Based on a 166 MHz high-performance CPU and extensive flash memory, the SCD2200 performs a wide range of control functions, from simple data acquisition to sophisticated closed-loop algorithms through a user-friendly sequence configurator supporting graphic and literal programming languages compliant to IEC 61131-3 & IEC 61499.

The SCD2200 is highly scalable with both powered (BP-x) and non-powered (BPLN) backplanes. The smallest configuration is available in a compact 2-slot integrated-power backplane (BP-2). Powered backplanes do not require a separate power supply module, allowing full utilization of slots. BPLN backplanes are available in 4, 6, or 12-slot variations, and BP-x backplanes are available in 2, 4, or 6-slot variations. Configurations can be expanded up to 64 slots per logical node and are suitable for indoor or outdoor mounting within an IP65/NEMA4 certified enclosure.

FoxRTU Station Software

The FoxRTU Station software is an integrated operating environment that combines configuration, programming, development, and maintenance in one simple-to-use package. It provides a single, highly intuitive user interface to view, edit, and diagnose SCD2200 solutions.

FoxRTU Station offers role-based access control to restrict system features to authorized users, eliminating the need to switch between software packages or engage in complicated programming.

With its embedded IEC-61131-3 compliant standard, the system supports:

• Ladder Logic
• Structured Text
• Function Block Diagrams
• Sequential Function Charts
• Instruction Lists
• Flowcharts

Pre-programmed function blocks facilitate the addition of new capabilities to SCD2200 RTU solutions.

Architecture

The SCD2200 architecture is based on a bus structure, connecting all RTU functional blocks: CPU, I/O modules, and communication modules. These modules support communication line interfaces and are hot-swappable. I/O modules can be easily installed or removed using standard DIN 41612 connectors and feature front-mounted diagnostic and indication LEDs.

Figure 2 - SCD2200 Bus Architecture: Depicts a system with Communication Channels, Power Supply Module, Processor Module, Secondary Processor (Optional), Communication Modules, and I/O Modules (Analog Input, Digital Input, Analog Output, Digital Output) connected via a Dual RS-485 Backplane.

Hardware Layout

The SCD2200 is a modular computing device composed of modules that plug into a backplane. There are two types of backplanes:

• Passive (BPLN) backplanes: Powered by Power Supply (PS-xx) modules requiring an external AC or DC power supply.
• Integrated-power (BP-x) backplanes: Powered by an integrated 5V supply and require an external 12V DC power source.

BPLN backplanes are available in 4, 6, or 12-slot variations, and BP-x backplanes are available in 2, 4, or 6-slot variations. Multiple backplanes can be linked to create an RTU with up to 64 modules. Rack mounting brackets are available for 19-inch rack installations.

A common arrangement for redundancy involves using dual CPUs. For BP-x backplanes, this means two CPUs. For BPLN backplanes, it involves two CPUs and two power supplies.

CP-3 Module

The 32-bit CPU module features:

• 166 MHz clock speed
• Real-time calendar clock
• One Fixed Ethernet 10/100 Base T Port
• Two optional communication ports for interface cards
• AT-HAYES compatible firmware protocol for modem and external radio devices
• Field-replaceable internal lithium battery
• Factory Reset option on the front panel
• Upgraded SRAM to 512 KB and SDRAM to 64 MB

The CP-3 module supports both MC-3 and MC-31 modules in a mixed communications environment. Refer to the SCD2200 Hardware User's Guide (B0780AE) for more details.

MC-31 Optional Communication Module

The MC-31 communication module is an optional module supporting various communication line interfaces. It includes a fixed Ethernet port and two optional communication ports for interface cards. Available optional communication cards include:

• IOPT D: V.34 PSTN Dial
• OPT F: Serial over optical
• OPT H: Hart Bell 202-1 to 15 devices multi-drop
• OPT I: Isolated serial (RS-232, RS-485, RS-422)
• OPT II: Isolated Dual channel Serial port-option board (RS-232, RS-485, RS-422)
• OPT L: V.23 2/4 wire for leased line and packet data radio interface support
• OPT R2: Spread Spectrum 900 MHz Australian version
• OPT R3: Spread Spectrum 2.4 GHz International version

• OPT T3: 10/100BaseT Ethernet

The MC-31 module requires the CP-3 module as a prerequisite. Figure 4 - MC-31 Communication Module: Displays the MC-31 module.

Input/Output (I/O) Modules

Common characteristics of I/O modules include HCMOS technology, optical isolation, and address-free design. Front-mounted diagnostic LEDs and indication LEDs facilitate quick disconnect of I/O terminations.

Available I/O modules include:

• Analog input modules (AI-10 and AI-10-V)
• Analog output modules (AO-3)
• Digital input modules (DI-5 and DI-10)
• Digital output modules (DO-1, DO-2, and DO-6)
• Combination Analog/Digital IO Modules (IO-3 and IO-5)

Figure 5 - Typical SCD2200 I/O Modules: Shows examples of DI-10, AI-10, and DO-2 modules.

Power Supply Modules

Available power supply modules are:

• PS-12 AC input, 100 to 240 VAC (without 24 VDC isolated converter)
• PS-22 DC input, 20 to 60 VDC (without 24 VDC isolated converter)
• PS-12 AC input, 100 to 240 VAC (with 24 VDC isolated converter)
• PS-22 DC input, 20 to 60 VDC (with 24 VDC isolated converter)

Power supply modules can be plugged in or out while the RTU backplane is powered on, but the input power supply (AC or DC) must be disconnected first. These modules are required only for BPLN backplanes, not for BP-x backplanes.

Backplanes

Backplanes host all SCD2200 modules, enabling communication between modules and distributing power. There are two types:

• BPLN (passive) backplanes: Require a PS-xx module connected to an external AC or DC supply. Available in 4, 6, and 12-slot variations.
• BP-x (integrated-power) backplanes: Have an integrated 5V power supply and require an external 12V DC power source. Available in 2, 4, and 6-slot variations.

Multiple backplanes can be linked to create an RTU with up to 64 modules. Backplanes are designed for surface mounting and come with mounting brackets for 19-inch rack installations.
