5.2 PRODUCT SETUP
The C30 relay does not support power metering. As such, the
settings are not applicable.
DEADBAND
NOTE
The C30 relay does not support energy metering. As such, the
DEFAULT DEADBAND
NOTE
The
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The
DNP MESSAGE FRAGMENT SIZE
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays, check
the "DNP Points Lists" C30 web page to view the points lists. This page can be viewed with a web browser by enter-
ing the C30 IP address to access the C30 "Main Menu", then by selecting the "Device Information Menu" > "DNP
NOTE
Points Lists" menu item.
The
DNP OBJECT 1 DEFAULT VARIATION
default variation number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation
response when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. Refer to the DNP implementation section in
appendix E for additional details.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the C30 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
5
master can operate a single point for both trip and close, or raise and lower, operations. The C30 can be configured to sup-
port paired control points, with each paired control point operating two virtual inputs. The
setting allows configuration of from 0 to 32 binary output paired controls. Points not configured as paired operate on
POINTS
a one-to-one basis.
The
setting is the DNP slave address. This number identifies the C30 on a DNP communications link. Each
DNP ADDRESS
DNP slave should be assigned a unique address.
The
DNP TCP CONNECTION TIMEOUT
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection will be
aborted by the C30. This frees up the connection to be re-used by a client.
Relay power must be re-cycled after changing the
effect.

PRODUCT SETUP
 DNP / IEC104
 POINT LISTS
The binary and analog inputs points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104 protocol, can
configured to a maximum of 256 points. The value for each point is user-programmable and can be configured by assigning
FlexLogic™ operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
