Figure 9-10 PMU-Specific Configuration
You configure the specific settings for the communication protocol in the top section of this settings dialog. In
the bottom section, you specify the corresponding PMU-specific settings.
In order to permit a better configuration of larger wide-area supervision systems, changes have been imple-
mented in the IEEE C37.118 communication configuration that permit a flexible IP configuration without the
loss of safety aspects in the systems administered.
Configurable placeholders are permitted for each PDC/IP address with the
TCP
PMU transmission protocol in
general and with
UDP
in the
Communication mode commanded operation
. These placeholders allow you
to define a range of IP addresses where they are accepted within these accesses. The purpose of this is to
permit each individual device or system access within the respective system without limits with regard to their
hierarchy level. Therefore, with regard to security aspects, the limitation to individual IP addresses is elimi-
nated. You are thus allowed to configure complete sections of IP addresses in each PMU and, as a result, very
flexible when making changes to the configuration of the entire system, for example. The placeholder char-
acter must follow consecutively at the bit level, starting with the bit with the lowest value.
