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.
