The RTU150 is an data collector/gateway which provides SCADA network connectivity on the slave side and configurable interfaces on the master side, e.g. Modbus RTU master, as well as the local I/O. Supported SCADA protocols on the slave side are DNP3, Modbus RTU, IEC60870-5-101 and IEC60870-5-104. RTU150 also supports the standar protocol SNMPv1.
When configured as a gateway, the RTU150 works as a data concentrator on a Modbus network being Modbus RTU master on one side and a RTU slave on the other side.
