FastNet RTU

The FastNet is a compact RTU that can be used both for data acquisition and for remote control. It also works as ­protocol converter and communication gateway. It is for different automation applications such as SCADA, CP and Power grids networks. The FastNet offers 18 digital inputs, 8 analog inputs and 14 digital outputs – all of which can be extensively configured. The FastNet supports a number of communication options. It has one RS‑485 connection, five RS‑232 ports and an RJ45 port for 10/100 Ethernet. Port forwarding is available for all the serial ports that allows traffic to/from the SCADA port to be sent transparently through the RTU from/to a slave device.

The FastNet supports the most common SCADA protocols. The serial IEC 60870‑5‑101 and Modbus RTU, the IP-based IEC 60870-5-4‑104 and both the serial and IP transport of DNP3 are available.  The device may be used as a Modbus RTU master for up to 5 slave RTUs. Six FastNet units can therefore be daisy-chained for additional I/O. For SCADA communication Modbus RTU can then be converted to one of the other supported protocols.
