    As a more compact version of the SEL-3530, the SEL-3530-4 Real-Time Automation Controller (RTAC) is also apowerful automation platform that combines the best features of the embedded microcomputer form factor, embeddedreal-time operating system, and secure communications framework with IEC 61131-3 PLC programmability.

    Major Features and Benefits Simple Setup With ACSELERATOR RTAC SEL-5033 Software. Build a system quickly using preconfigured

    device templates for SEL relays and other communications connections. The Tag Processor provides methods to map data relationships between communication protocols visually.

    Multiple Device Functions in One Reliable Device. Use a single RTAC as a protocol gateway, RTU, logic processor, PAC, engineering port server, event processor, and system-wide SER logger/viewer.

    Proven Reliability. The RTAC is designed and tested to withstand vibration, electrical surges, fast transients, and extreme temperatures which meet or exceed protective relay standards and IEEE 1613 Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations.

    Product Overview

    Functional Diagram

    IEC 61131 Logic EngineAs depicted in the functional diagram, each RTACincludes an IEC 61131 logic engine that is preconfiguredto have access for all system tags, IED data, diagnostics,alarms, security events, and communications statisticsfor use integrating your system. The system has no func-tional separation between those tags mapped for commu-nication protocols and those used in programmable logic.This architecture greatly simplifies system configurationeffort because no additional selection is required in orderto identify tags used by the logic engine. You simply useany needed IED data, calculated values, and system tagsin deterministic logic for the control of critical applica-tions.

    Management of the task processing sequence and solverate in the RTAC is similar to that for traditional PLCs orPACs. The fastest processing rate is 4 ms. Optimize theprocessor utilization by setting the processing rate nofaster than necessary for your application.

    Task processing in the logic engine includes protocolI/O, system management, and any custom logicprograms you create using Structured Text (ST), LadderLogic Diagram (LD), or Continuous Function Charts(CFC). CFC programs are a type of IEC 61131-3Function Block Diagram (FBD) that provide moreprogramming flexibility than standard FBDs.ACSELERATOR RTAC includes the IEC 61131-3 and TagProcessor editors you will use to manage any protocolinformation and custom logic needed for your system.

    Manage User Accounts and Alarms in Web ServerThe built-in RTAC web interface provides the ability tomanage user accounts and system alarms remotely. Eachuser account has a unique user name, password, andassigned role that defines system permissions. You canalso configure the RTAC to use LDAP central authentica-tion for user account management. The system includesweb pages for monitoring user logs and maintaining net-work policies.

    Logged tag values and system events provide a system-wide Sequence of Events report. View the logs online oruse ODBC connectivity to download them to a centraldatabase.

    You can also configure Ethernet connections and monitorsystem status from the web interface. All of the Ethernetports can operate on independent networks, or you canbind them for failover operation.

    Flexible Engineering AccessAccess Point Routers in the RTAC provide a means forcreating transparent connections between any two ports.A transparent connection is a method for using the RTACas a port server to connect remotely to an IED. Simplelogic in the RTAC enables remote engineering accessonly through supervisory commands.

    Product OverviewSeamless System ConfigurationACSELERATOR RTAC is a Microsoft Windows com-patible configuration software for offline and online usewith the RTAC. A project in ACSELERATOR RTAC con-tains the complete configuration, settings and logic, foran individual RTAC device. Preconfigured device tem-plates are available for you to add all device and masterconnections to the project tree view.

    Once you create the settings for a specific deviceconnection, improve engineering efficiency by saving acustom device template for later use with similarprojects. Share custom templates via e-mail or networkfor even greater savings.

    The Tag Processor view facilitates the mapping ofoperational data quickly between IEDs and SCADA.ACSELERATOR RTAC is compatible with MicrosoftExcel and other programs, so you can save time andincrease accuracy by copying SCADA maps from thesource.

    There is no need to install or learn more than onesoftware interface. Use the Structured Text, LadderDiagram, or Continuous Function Chart editors includedwith ACSELERATOR RTAC to develop customIEC 61131 logic.

    Data Concentration and Protocol ConversionConfigure each serial or Ethernet port to use any of theclient, server, or peer-to-peer protocols available for theRTAC. For example, when you use IEEE C37.118 proto-col to receive synchrophasor messages, you can mapanalog or Boolean tags and timestamps to DNP3 andsend the data to SCADA very efficiently. You can alsomap data to IEC 61850 GOOSE messages for high-speedcontrol schemes.

    Additionally, when you need to define relay connectionsin a primary/backup arrangement, use the Tag Processorto map relay tags so that the master stations will receivepower system information only from the active relay.

    The RTAC can integrate synchrophasormessages from the IEEE C37.118 protocolinto SCADA protocols, such as DNP3 orModbus. Easily include the source PMUtime stamps and time quality attributes inthe SCADA message to allow for system-wide usage of synchrophasor data.

    Within the RTAC logic engine, you canperform complex math and logiccalculations on synchrophasor data fromC37.118 compliant devices.

    The RTAC also synchronizes the timeclocks in attached devices that accept ademodulated IRIG-B time signal. TheRTAC regenerates the demodulatedIRIG-B signal from an external modulatedor demodulated source; this signal isprecise enough for synchrophasorapplications.

    Control Systems

    Ordering Options

    The custom logic, communications proto-cols, and I/O in the RTAC, SEL-2411 andSEL-2440 permit you to implement com-plete control systems, whether you per-form discrete sequences, continuouscontrol, monitoring, or asset management.SEL subjects its products to tests for harshenvironments, so you can be confident thatyour control system will work reliably intough applications. Minimize loop wiringand simplify commissioning by installingcontrols close to process equipment andintegrating them with industry standardcommunications protocols. Additionally,the SEL-3354 Embedded AutomationComputer can provide HMI and dataarchiving functions.

    Use a powerful IEC 61131 logic engine todesign custom control programs in theRTAC. You can set the logic solve rate andprogram execution order to meet yoursystem requirements. Operate the RTACas a master controller and use SELOGIC

    control equations in the SEL-2411 andSEL-2440 to perform distributedsequential or continuous controlalgorithms.

    With a variety of physical interfaces andopen protocol options, such as IEC 61850GOOSE messaging, the RTAC makessystem integration simple. It will reduceengineering time and complexity, so thatyou can focus on improving productivityand efficiency rather than on fixingcommunication problems.
