5.5 Access Rights
Access Rights for Configuration and Maintenance
To determine access rights, you have to set up passwords when configuring the device. You have to specify an
activation password and a maintenance password; chapter 7.3.6.5 describes how to set up passwords.
The activation password is required to enable parameter changes in the device.
The maintenance password is required to make changes in the device using the Maintenance tab.
Access Rights for Communication
The access rights for the communication via Ethernet with Modbus TCP protocol are made for port 502 and
for the user port. You can assign either full access rights or read-only authorization; chapter 7.3.6.2 describes
the settings.
You can also determine the access rights for serial communication using the Modbus RTU protocol. You can
assign either full access rights or read-only authorization; chapter 7.3.6.3 describes the settings.
No access rights are required when serial communicating via the IEC 60870-5-103 protocol.
Communication via Ethernet with IEC 61850 server protocol and serial communication with
IEC 60870-5-103 protocol do not require any access rights.
NOTE
If you do not specify new passwords, the factory-set default passwords (see chapter 7.3.6.5) are valid.
