Dual-processor system

EPPE CX  features an integrated dual-processor system with two separate processors for the user interface and for the communications interfaces. This is the only way to ensure user-friendly operation, fast and reliable data transfer and easy integration into any network.

Transfer of parameters by USB flash drive

If neither a wired nor a wireless communication network is 

available, parameters can also be transferred directly to an 

EPPE CX using a USB flash drive. Saved measurement data can also be transferred quickly and easily to a USB flash drive with-out a direct communication connection.

Communication interfaces

The EPPE CX measuring system provides the following interfaces for integration in communication networks:

  • Electric Ethernet
  • Optical Ethernet (optical fibre)
  • USB (active/passive)
  • RS485
  • RS232
  • Integrated web server
  • GSM/GPRS modem
  • UMTS router
  • EPPE CX also supports communication protocols such as
  • IEC 61850 and Modbus.

Data communication via UMTS router

As reliance on renewable energy sources grows, increasing numbers of power quality analysers are used in plants which do not have a wired communication network. Automatic data download using a mobile network via UMTS, for example, is recommended as an alternative to downloading data onto a USB flash drive.

This means that communication and data transfer are fully independent of any kind of wired infrastructure. What is more, even in rural areas and small towns it is possible to reach a high data transmission rate of up to 100 Mbit/s when downloading the measurement data. The UMTS router, which is installed in close proximity to the power quality analysers, establishes an Internet connection and the data can be transferred easily and reliably to a central server (database) by means of a VPN tunnel.
