Class Description
NOTICE
RISK OF UNAUTHORIZED ACCESS TO THE DEVICE
IEC61850/MMS does not provide any authentication mechanisms. If the write access for
IEC61850/MMS is activated, then every client that can access the device using TCP/IP is
capable of changing the settings of the device. This in turn can result in an incorrect configuration
of the device and to failures in the network.
Only activate the write access if you have taken additional measures (for example Firewall, VPN,
etc.) to reduce possible unauthorized access.
Failure to follow these instructions can result in equipment damage.
