The RTAC is the only automation platform that combines an IEC 61131 logic engine and industry standard communications with SEL Mirrored Bits® communications and IEEE C37.118 synchrophasors for unmatched control and system monitoring. The optional web-based HMI completes the RTAC as the perfect automation solution.
#SEL RTAC AS MODBUS SERVER SOFTWARE#
The RTAC is bundled with intuitive configuration software to quickly configure large automated systems. The RTAC also gives integrators the necessary tools to easily integrate and concentrate information from the wide variety of microprocessor-based devices found in today’s substations. The RTAC features secure communications, advanced data concentration, high-speed logic processing, flexible engineering access, and protocol conversion capabilities between multiple built-in client/server protocols. The RTAC can provide any degree of functionality from that of a simple intelligent port switch to the sophisticated communication and data handling required for advanced substation integration projects. The RTAC combines an embedded microprocessor-based hardware platform, wide operating temperature range, real-time operating system, and secure communications with flexible, feature-rich IEC 61131-compliant programmability. For more than thirty years, SEL has offered unmatched local technical support, a worldwide, ten-year product warranty, and a commitment to making electric power safer, more reliable, and more economical.Available in a 1U half-rack, 1U full-rack, or 3U full-rack chassis, the SEL-3530 and SEL-3530-4 Real-Time Automation Controllers (RTACs) are powerful automation platforms, designed and tested to provide years of service in tough substation and plant environments. SEL serves the power industry worldwide through the design, manufacture, supply, and support of products and services for power system protection, monitoring, control, automation, communications and metering. The SEL-3505-3 RTAC includes security features like centralized authentication via Lightweight Directory Access Protocol (LDAP), logging of all user access, port control, and innovative intrusion detection and alarming that utilize an accelerometer and optical sensor. Designed for data concentration, protocol conversion, and control applications, the SEL-3505-3 operates with a wide variety of communications interfaces and protocols, including DNP3 serial, DNP3 LAN, Modbus® RTU, Modbus TCP, IEC 60870-5 101/104 Server, 2179 Client, IEC 61850 GOOSE, IEEE C37.118, and SEL protocols. Added support for Axion Recording Group channel calculations. Encrypted port 1217 communications between ACSELERATOR RTAC software and RTAC firmware. Enhanced User API to include support for adding, deleting, and mod-ifying user accounts. auxiliares SEL-735 G SEL Distributed Port Switch (LMD), Modbus RTU/TCP.
