21.1.2 Configuration B (Recommended)
In this configuration, the Pump Station receives the level over a direct communications link with the
Reservoir Monitor. This is the preferred configuration.
The Pump Station must be configured as a DNP Master (choosing remote level and configuration B for the
pump station will ensure this is the case).

21.1.3 Configuration C
This configuration is also used when there is no direct communications link between the Pump Station and
the Reservoir Monitor. In this mode, the Pump Station will establish a second connection to the DNP3 Master
(MTU) in order to retrieve levels from the Reservoir Monitor.
This configuration can be used instead of Configuration A when there is no redundant MTU available.
When using this configuration Connection Manager must be enabled on the Pump Station. The Pump
Station must also be configured as a DNP Master (choosing remote level and configuration B for the pump
station will ensure this is the case).
