A The P
OSITION
indicates the position of each analog input on the back panel of the
module.
B The I
NPUT
scroll box allows user to select the type of the signal to be measured (AC
voltage 115 V, AC current 1 A, AC current 5 A, DC current 0-20 mA or DC voltage ±10
V).
C The A
DJUSTMENT
text field allows user to enter a correction factor to adjust the
accuracy of the measurement.
2.5 Acquisition with Sampled Values
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.
