DNP 3.0 OPC Server features2.4.3.DNP3 (Distributed Network Protocol) is a de-facto communication protocol for commu-nication between SCADA master stations (control centres), RTUs, protection and controldevices and meters. It is used mainly in electric and water utilities. The COM600 incor-porates the DNP 3.0 master LAN/WAN for Ethernet based communication with stationdevices.The DNP LAN/WAN OPC Server supports the following features:• OPC Data Access v. 1.0/2.0• OPC Alarms and Events specifications v. 1.10• IEC 61850 data modeling• System supervision:• DNP channel communication• DNP device communication• Level of DNP implementationModbus OPC Server features2.4.4.Modbus is a de-facto standard communication protocol used in electrical and industrialprocess data exchange between substation devices such as IEDs, meters or PLCs withCOM600.The Modbus OPC Server is intended for connecting simple Modbus devices like energymeters and input/ouput modules. As the protocol is based on scanning the state of theinputs of the device, it depends on the scan rate how short signal transients are registered.No events or time stamps are supported.The Modbus messaging service provides a client/server communication between devicesconnected on an Ethernet TCP/IP network. This model is based on four types of messages:request, confirmation, indication, and response.A system using Modbus TCP/IP can include different types of devices. There can beModbusTCP/IP client and server devices connected to an TCP/IP network. There canalso be devices such as bridges, routers and gateways for connections between the TCP/IPnetwork and a serial line sub-network, permitting connections to Modbus serial line clientand server end devices.The Modbus OPC Server supports the following features:• OPC Data Access v. 1.0/2.0• OPC Alarms and Events specifications v. 1.10• IEC 61850 data modeling• System supervision:• Modbus channel communication• Modbus device communication21COM600 series 5.01MRS758690Master Protocols (Ethernet) and Applications Technical Refer-ence Manual
