FastNet RTU

FastNet is a compact RTU designed fore use in electricity transmission and distribution networks.

FastNet base units supports:

  • 18 digital inputs
  • 14 digital outputs
  • 8 analogue inputs
  • 9-30 V supply
  • 1 Ethernet port
  • 5 RS232 ports
  • 1 RS485 port
  • 1 R-Bus expansion port

FastNet RTU's digital outputs are flexible and can be assigned individually or as 'paired outputs'.  The unit also fully supports 'select before exeute' output function, allowing additional control security.  The digital outputs are fully configurable and support both pulse and toggle options, and the pulse times are individuall user configurable. Digital inputs can also be assigned individually or in pairs and have a programmable 'debounce' or 'delay' time. When assigned as a pair, the 'on' and 'off' delay times can be configured in order to avoid unwanted state changes.

Chatter Control - Increase Security

The digital inputs of the FastNet RTU support 'chatter control', preventing an input from permanently sending changes of state, if connected to faulty equipment which is changing its value constantly.

Analogue Inputs

The 8 analogue inputs are fully configurable and have programmable sampling times and support for 'dead-banding' in order to reduce data traffic without comprimising performance.

Flexible Communication Solution

FastNet supports both polled and ‘event-triggered’ communication sometimes referred to as ‘report-by-exception’ communication. Since both modes are supported it is usual that a background health poll routine is supplemented with event triggered communication. 

FastNet supports a number of communication connection options. It has one RS485 connection, five free RS232 ports while an RJ port provides Ethernet connection. There is one RS232 port that is reserved for service and support and another for programming on the front panel. Port forwarding is available on all communication ports.

Easy I/O Expansion

The FastNet is designed to support either additional ‘extended I/O’ modules or further ‘daisy-chained’ FastNet-RTU’s.
