17.12.2 Application
To safeguard the interests of our customers, both the IED and the tools that are accessing
the IED are protected, by means of authorization handling. The authorization handling of
the IED and the PCM600 is implemented at both access points to the IED:
• local, through the local HMI
• remote, through the communication ports
The IED users can be created, deleted and edited only with PCM600 IED user
management tool.
