The subjects defined and supported by each server protocol are indicated in the following table:
Specifying Access Rights
For each subject, PROFINET I/O Devices from GE Automation & Controls provide predefined access rights.
Predefined Access Rights
Using the SNP Slave Application Protocol to update firmware on a PROFINET I/O Device, the Anonymous
Subject is granted the same Service Request PRIV Level as the highest PRIV Level user that currently has no
password. This equates to PRIV Level 4 user on PROFINET I/O Devices which allows Write Access to support
the Firmware Update Functionality.
Physical Access
The Web Server Password Reset feature requires physical access to the PROFINET I/O Device to assign the
Firmware Updater password.
Enforcement
Each of the PROFINET I/O Devices enforces the access rights for the data and services that it provides.
