RTAC SEL-3530-4 Real-Time Automation Controller As a more compact version of the SEL-3530, the SEL-3530-4 Real-Time Automation Controller (RTAC) is also a powerful automation platform that combines the best features of the embedded microcomputer form factor, embedded real-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 communications 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. Depend on a rugged device designed and tested to meet or exceed protective relay standards for vibration, electrical surges, fast transients, and extreme temperatures, as well as meet or exceed IEEE 1613, Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations. IEC 61850. Integrate high-speed control schemes between the RTAC and relays with IEC 61850 GOOSE peerto-peer messaging. Poll and send data sets and reports from other IEDs with IEC 61850 MMS client/server. Integrated HMI. Build custom human-machine interface (HMI) displays quickly and easily without the need for mapping data tags. Because it is web-based, no special software is needed for viewing HMI displays. Protection Against Malware and Other Cybersecurity Threats. Protect your RTAC system with exe-GUARD®, which uses advanced cryptographic algorithms to authorize the execution of any program or service on the system. Any tasks not approved by the whitelist are blocked from operation. User Security. Assign individual user and role-based account authentication and strong passwords. Use Lightweight Directory Access Protocol (LDAP) for central user authentication. Integrated Security Management. Comply with NERC/CIP user authentication, logging, and port control requirements. Standard IEC 61131-3 Logic Design. Create innovative logic solutions directly in ACSELERATOR RTAC using any of the editor tools: Tag Processor, Structured Text, Ladder Logic, or Continuous Function Chart. Flexible Protocol Conversion. Apply any available client or server protocol on any serial or Ethernet port. Each serial port can be used in software-selectable EIA-232 or EIA-485 mode. The two rear Ethernet ports can optionally be copper or fiber-optic connectors. Synchrophasor Technology Included. Use the IEEE C37.118 client protocol to integrate synchrophasor messages from relays or PMUs in your system. These messages can be used for logic and control in the station or converted to DNP3 or other protocol for SCADA usage. Standard Data Management. Map and scale data points easily between protocols in small and large systems. You can also normalize IED data into common data types, time-stamp formats, and time zones. Single-Point Engineering Access. Gain engineering access to station IEDs through a single serial port, external modem, or high-speed network connection. Schweitzer Engineering Laboratories, Inc.

Product Overview Functional Diagram Synchronized Time exe-GUARD Protected RTAC® Security and Firewall System Database Structured text Ladder diagram ➤ Continuous function chart ➤ IEC 61131 Logic Engine As depicted in the functional diagram, each RTAC includes an IEC 61131 logic engine that is preconfigured to have access for all system tags, IED data, diagnostics, alarms, security events, and communications statistics for use integrating your system. The system has no functional separation between those tags mapped for communications protocols and those used in programmable logic. This architecture...

Seamless System Configuration RTAC is a Microsoft® Windows® compatible configuration software for offline and online use with the RTAC. A project in ACSELERATOR RTAC contains the complete configuration, settings and logic, for an individual RTAC device. Preconfigured device templates are available for you to add all device and master connections to the project tree view. ACSELERATOR Once you create the settings for a specific device connection, improve engineering efficiency by saving a custom device template for later use with similar projects. Share custom templates via email or network for...

Substation SCADA, Report Retrieval, Engineering Access, and Alarm Notification The RTAC can act as a data concentrator by using protocols such as IEC 61850 MMS client, Modbus®, DNP3, IEC 61850 GOOSE, or Mirrored Bits® communications to integrate both serial and Ethernet IEDs. Enable logging on any system or IED tag to view and archive a station-wide event record. The RTAC Ethernet connection provides a means to remotely access the system to monitor logs and diagnostics. First establish a remote connection with any IED connected to the RTAC through Engineering Access communications channels. Then...

Real-Time Control and Logic Processing The built-in logic processor provides highspeed control and transfer of signals from SEL MIRRORED BITS devices or devices using other protocols. The RTAC can serve as the system controller and SCADA gateway to eliminate costly equipment (such as breakers, interposing relays, and wiring) while also reducing engineering and labor costs. Engineering Access SCADA SEL-2725 Five-Port Ethernet Switch The intuitive ACSELERATOR RTAC software provides simple setup of analog and binary tags from any device in the system. Integrated tools scale values and create logic...

Control Systems The custom logic, communications protocols, and I/O in the RTAC, SEL-2411, and SEL-2440 permit you to implement complete control systems, whether you perform discrete sequences, continuous control, monitoring, or asset management. SEL subjects its products to tests for harsh environments, so you can be confident that your control system will work reliably in tough applications. Minimize loop wiring and simplify commissioning by installing controls close to process equipment and integrating them with industry standard communications protocols. Additionally, the SEL-3354 Embedded...
