The relay supports full Public Key Infrastructure as defined by

IEC 62351-9. With this, the user can ensure that the certificates

used in secured communication are from a user-approved

provider instead of device self-signed certificates.

User accounts can be managed by PCM600 or centrally. A

central account management is an authentication infrastructure

that offers a secure solution for enforcing access control to

relays and other systems within a substation. This incorporates

management of user accounts, roles and certificates and the

distribution of such, a procedure completely transparent to the

user. The central server handling user accounts can be, for

example, SDM600 or an Active Directory (AD) server such as

Windows AD.
