Things that You Need to Know About the SCADA Data Gateway
A software and hardware solution that connects to several data sources like the IEDs and give one and central access point to connect with each device is known as the data gateway. This is one data communication device offering that remote network with connectivity to such host network.
The SCADA concentrator gateway device would provide communication to the remote network or an autonomous system which is out of bounds for the host network nodes. Gateways are going to serve as entry and also an exit point of the network and all data are routed in or out and they must first pass through and must communicate with the gateway to make use of the routing paths. Generally, the router is configured to work as the gateway device in computer networks.
Any kind of work would have a limit so all the communication that is placed in the network is carried out through using the devices which are attached to it and such would include the routers and switches. When the network node would like to connect with a network/node which is outside of such network or the autonomous system, then the network will need the gateway that is familiar with such routing path of the other remote networks.
The gateway is applied at the network's boundary to manage all the data communication routed externally or internally from the network. Other than those routing packets, the gateway has information about the internal paths of the host network and the learned path about different remote networks. If the network node wishes to communicate with the foreign network, this is going pass the data packet going to the gateway and such then sends it to the destination with the greatest path available.
The SCADA data gateway does the job of the OPC server or protocol translator. This translates between the many products of any number. This would also come with a protocol analyzer. Has a built-in equation editor which supports the making or the creation of new data points according to the raw data points or the other equation points. Also, there is RBE or report by exception in which it only transmits the data changes and this means there is saving the bandwidth of the communication channel.
You must know such would support DNP3 secure authentication 61850 simulator and such is also going to support the selective logging the different event data in a log as Sequence of Events file. The Communication Protocol Analyzer Window show and decodes such transmitted and the received messages. Also, this would permit translation between the data types and would control methods from various protocols. There is also mapping of points between the Slave and Master components and others.
