CAUTION!
Do not leave the EMR-3MP0 unsupervised as long as PowerPort-E still keeps some access
area unlocked. Lock your PC during your absence, or at least reset the access
permissions. This can be done by a double-click on the lock symbol in the status line on
the bottom margin of the PowerPort-E window (or, alternatively, via the menu [Device →
Reset to Parameter "Read Only" Status].

Network Access
Access via PowerPort-E
One of the fundamental requirements of »IT Security« is to prevent unauthorized persons
from accessing the own systems, including the protective device EMR-3MP0. The
EMR-3MP0 offers access via its front panel and via the operating software PowerPort-E.
Since the access via front panel is only possible for someone who is located directly in
front of the device the risk should normally be rather low, compared to the risk of
unauthorized access via PowerPort-E, especially if the EMR-3MP0 is part of an Ethernet /
TCP/IP network.
After commissioning of the EMR-3MP0, it is recommended to deactivate the PowerPort-E
access via Ethernet; this can be done with the setting parameter [Device Para / HMI /
Security] » PowerPort-E via Eth«.
There is also the option to deactivate the PowerPort-E access via the Modbus tunnel; this
can be done with the setting parameter [Device Para / HMI / Security] »PowerPort-E via
Modbus«.
There is also the option to deactivate the PowerPort-E access via the USB interface; this
can be done with the setting parameter [Device Para / HMI / Security] »PowerPort-E via
USB«.
NOTICE!
If PowerPort-E is used to deactivate the PowerPort-E access, then the current session gets
automatically terminated.
SCADA Communication
It is to be noted that there are always certain security risks related to the use of SCADA
protocols. Detailed information can be found in the technical literature.
Intranet Security
If the Ethernet interface of the EMR-3MP0 is connected to a network it is the responsibility
of the user to maintain all necessary means required for the security of the company
network. In particular, it must be guaranteed that external access (i. e. out of the
