5.2 PRODUCT SETUP
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 T35 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
master can operate a single point for both trip and close, or raise and lower, operations. The T35 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

a one-to-one basis.
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 T35. This frees up the connection to be re-used by a client.
Relay power must be re-cycled after changing the
effect.

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.
The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) is shown below.

Up to 256 binary input points can be configured for the DNP or IEC 60870-5-104 protocols. The points are configured by
assigning an appropriate FlexLogic operand. Refer to the Introduction to FlexLogic section in this chapter for the full range
of assignable operands.
