Figure 13: Analog inputs configuration section

A The P indicates the position of each analog input on the back panel of the
OSITION
module.
B The I scroll box allows user to select the type of the signal to be measured (AC
NPUT
voltage 115 V, AC current 1 A, AC current 5 A, DC current 0-20 mA or DC voltage ±10
V).
C The A text field allows user to enter a correction factor to adjust the
DJUSTMENT
accuracy of the measurement.
The RPV311 data acquisition can be performed by Sampled Values data, incoming of
Merging Units. The acquisition is done by connecting the Process Bus Ethernet port to
the Sampled Values generator.
If the acquisition is done by Sampled Values, there is no physical link to configure.
The configuration is performed by Subscription links. Each subscription link contains
data of 4 current (Phases A, B, C and Neutral) and 4 voltage (Phases A, B, C and
Neutral) circuits.
Once a subscription link is created, the RPV311 automatically configures the first
channels as current and the last as voltage, as shown in Figure 86. This is done
because the Merging Units send the Sampled Values package according to the IEC
61850-9-2LE.
The RPV311 processing module can be configured with up to 8 Subscription links.
