E-NODES

Technology

The technology enabling the E-Node concept is divided into Two distinct elements, the 'Core technology' and the 'Peripheral technology'.

Core Technology

Highly integrated electronics embedded within every active E-Node provides the following facilities:-

  • 32 Bit performance: A fully 32 bit microprocessor running with a 64 MHz system clock yielding a very high performance.
  • 512 Kbyte Flash memory: Embedded 32 bit wide flash memory for system and user program storage.
  • 2000 Kbyte backup Flash memory: For secure Two stage programming of system and user programs plus general storage for user source files and general backup tasks.
  • 8 Kbyte Fram store: Reliable random access non volatile storage for user variables. 45 years data retention. No batteries to go flat!
  • E-Port Interface: A dedicated programming and set-up interface connected to a Personal Computer via the E-Node Programming Adaptor. All System and User software can be upgraded via this interface.
  • E-Net Interface: Using either a 'Control Area Network - CAN' or standard Ethernet hardware the E-Net links all nodes in a system. For nodes mounted on a common length of DIN rail a 20 way ribbon cable distributes E-Net, power and Earth.
  • 8 Segment Display: Providing Status, Progress and Communications information (active DIN rail mount nodes only).
  • Options Port: A factory fitted facility for providing options such as, additional serial flash memory, additional Fram storage, real time clock etc.
  • Peripheral Port: Used for interfacing to the wide variety of peripheral functions provided across the E-Node range.

Peripheral Technology

The Peripheral Technology is the circuitry the Core interfaces to via the Peripheral Port. It provides the individual functions that vary dependent on the node type. Details are given on the relevant pages.
