2022年4月1日 · Wind data storage and traffic control in substation host, substation server (DMZ), and substation firewall. Fig. 2 shows the counts in wind speed data against packets. One packet carries one wind speed value. There are three curves. The red curve is the wind data request by IEC 60870-5-104 packets in the internal network by the Substation Host.
both the firewalls. Fig. 1 shows an implied DMZ arrangement in the substations holding critical cyberassets, as defined by the NERC CIP requirements. In this design, the control system DMZ acts as a secure corridor between the SCADA network, or critical network, and the corporate network of the company. The DMZ supports

The STC Replicator is a client/server application that provides real-time data replication of the ADMS database to a SQL Server database residing in a demilitarized zone (DMZ). Historical data sets can also be replicated, so corporate users have access to near-real-time and historical data.
Firewalls also allow the creation of demilitarized zones (DMZ’s) in the utilities, where information about the utility’s operation can be accessed by the corporate network and outside contractors.
Servers in a Demilitarized Zone (DMZ) - VTScada by Trihedral
Configure the firewall between the SCADA network and the DMZ to allow only connections on the VTScada RPC port 5780 that are initiated from the SCADA network side. VTScada does not require any additional configuration for this, as long as at least one VTScada service includes the DMZ computer as a backup server on its server list.
