ETL600 R4 ETL600 - The secure communication solution for critical infrastructure ETL600 has been designed keeping the customers’ investment protection in mind by ensuring a seamless transition from today’s to tomorrow’s PLC solutions. Long-time tradition Power Line Carrier systems have been used for decades by Electric Power Utilities to transfer vital information for the operation and protection of the electric power grid. Despite the forced deployment of optical fibers in recent years, PLC systems have continued to be used as a cost efficient and reliable solution for mission-critical services, either as the main and only medium where installations of optical fibers are economically not justified, or as a backup solution for the most important services that are normally conveyed over broadband media. In recent years, technology advances brought about new opportunities for PLC applications, in particular related to higher bandwidth provisioning, integration into digital networks, combined with functional enhancements as well as ease and flexibility of use. These new possibilities - together with economic and reliability considerations which PLC is known for - have led to a remarkable revival of PLC systems worldwide. With ETL600, Hitachi Energy continues its successful line of PLC equip-ment, supporting all applications from legacy analog to most advanced digital solutions with a future-proof concept. ETL600 preserves all of the functionality of the proven ETL500 - with thousands of units in operation worldwide - and at the same time offers a range of unprecedented features which makes ETL600 the perfect fit for demanding communication infrastructure. The link to the future The transition from analog to digital communication needs to be properly addressed by any new design. Besides concurrently supporting legacy and modern applications, existing PLC terminals themselves must be re-usable and upgradeable to advanced and future-proof digital PLC technology. ETL600 has been designed keeping the customers’ investment protection in mind by ensuring a seamless transition from today’s to tomorrow’s PLC solutions with a smooth migration concept. No matter whether analog or digital applications are in your focus, ETL600 provides the solution to your operational communication needs with its universal and flexible system architecture. Designed for the harsh substation environment In order to provide the security and reliability that is expected from PLC, ETL600 incorporates extra measures, which contribute to providing high availability and protection against electromagnetic interference and damage due to overvoltage stress. Apart from complying with all relevant EMC/EMI standards, all interfaces including data ports are electrically isolated, hence providing additional protection againstover voltages, ground potential rise and ground loops beyond standard requirements.

ETL600 – ready for the future ETL600’s advanced design allows the integration of all kinds of analog and digital services via commonly used interfaces, based on IEC standards and ITU recommendations. No matter whether you are confined to traditional frequency planning or want to go beyond the typical 64 kbps of today’s digital PLC, ETL600 provides all the options as on-site pro-grammable features. Future-proof concept Bandwidth has always been a scarce resource for PLC. The need for more communication capacity brought about frequency congestion problems, which made the extension of the PLC network...

ETL600 – the future-oriented platform ETL600 preserves all the functionalities of the proven ETL500 and at the same time offers a range of unprec-edented features which makes ETL600 the perfect fit for demanding communication infrastructure. Universal architecture With its universal hardware and software architecture, ETL600 makes the choice between traditional analog and advanced digital PLC finally pointless and obsolete – in contrast to most conventional systems where the choice is final and irreversible. Using the same hardware components, the operating mode can be selected and changed by...

ETL600 automatically copes with difficult situations by making optimum use of the available spectrum by means of novel algorithms, based on Hitachi Energy ’s long experience with digital PLC in real networks. Your benefits • Universal architecture for digital and analog operation in the same platform • Operating mode configurable with a few mouse-clicks • Wide range of transmission channel bandwidth, programmable without exchanging hardware • SSB and Multi-Carrier (OFDM) digital modulation with Trellis Coding, user programmable on site • Extended carrier frequency range up to 1000 kHz, duplicating...

ETL600 – a step ahead in transmission speed ETL600’s novel adaptive signal processing algorithms ensure shortest transmission times for teleprotection, without compromising the security in any respect. Reliable teleprotection The transmission of protection commands is one of the most important tasks of PLC systems. PLC links have proven their reliability and security for decades, be it as the main channel or as backup for broadband systems, keeping in mind that the robustness of the transmission path is determined by the ruggedness of the power line itself – no other wire or fiberbound solution...

ETL600 – easy to access and to manage The ETL600 system features a very user-friendly Human Machine Interface software utility with built-in test func-tions for easy commissioning and maintenance. LAN/Ethernet connectivity The LAN600 service offers either transparent bridging/switching (including VLAN support) or IP routing (forward all or static routes), i.e. no external router is required when two LANs shall be interconnected via an ETL600 link, for example. The LAN600 can make use of the full broadband capacity or share it with other services. The Dynamic Speed Adaptation applies in either...
