3.6 Certificate handling
GUID-C9F2CFBF-1A4A-4237-A37F-50064A6E1E65 v1.1.1
A self-signed certificate is signed by the IED itself. Certificates use encryption to
provide secure communication over the network.
The certificate is always trusted during communication between the IED and
PCM600.
If Windows is configured to use UAC High the certificate has to be manually
trusted in a dialog box.
