Then Moxa’s MGate 5119 secured gateway might be just what the doctor ordered, and it can be used as a master on all the former networks, to collect data and exchange it with an IEC 61850 MMS system.
Security features are based on IEC 62443 and NERC CIP standards, and protocol encryption is included for critical communications between power SCADA systems and sub-station gateways.
“When retrofitting substation automation systems, connecting legacy power devices, such as a protective relay or remote terminal unit, to the network raises security concerns,” according to the company.
Time synchronisation is provided for a consistent time stamp, and a function is included to generate a substation configuration language (SCL) file – it “can easily generate SCL files through the web console and make them available almost immediately,” said Moxa.
For troubleshooting communication errors there are tools to diagnose protocol status and capture traffic.
2kV serial port isolation is included to comply with IEC 61850-3/IEEE 1613, and a operation is over -40 to 75°C.
Warranty is five years.
