(FlexAnalog parameters) such as power, current amplitude, voltage amplitude, power factor, etc. can be configured as
sources driving DCmA outputs. See Appendix A for a list of FlexAnalog parameters.
DCMA OUTPUT F1 RANGE
to work with different ranges. The three most commonly used output ranges are available.
DCMA OUTPUT F1 MIN VAL
used to control the mapping between an internal analog value and the output current. The setting is entered in per-unit
values. The base units are defined in the same manner as the FlexElement base units.
DCMA OUTPUT F1 MAX VAL
is used to control the mapping between an internal analog value and the output current. The setting is entered in per-unit
values. The base units are defined in the same manner as the FlexElement base units.

SETTINGS  TESTING  TEST MODE FUNCTION
 TESTING

The C30 provides a test facility to verify the functionality of contact inputs and outputs, some communication functions
and the phasor measurement unit (where applicable), using simulated conditions.
The test mode can be in any of three states: Disabled, Isolated, or Forcible.
The Disabled mode is intended for normal in service operation; relay protection, control and communication function is
normal. Test features are disabled, except channel tests and phasor measurement unit tests remain usable when
provided.
The Isolated mode is intended to allow the relay to be quickly placed in a state where the relay cannot negatively impact
the power system or other parts of the substation automation system. This is to allow changing settings, loading new
firmware, changing hardware modules, and changing communication connections. As far as practical all relay output
signals are blocked. Contact outputs are de-energized, latching outputs are frozen. Commands to bricks are blocked.
GOOSE transmissions have their "simulation" flag (also known as "test" flag) set, which results in the messages not being
accepted by compliant receiving devices that do not have a "Sim" data attribute set. The quality attribute of values that
can be output via 61850 MMS services are set to "invalid," which results in the values not being used for operational
purposes by compliant receiving devices. Direct I/O channel tests and PMU tests are usable on applicable models.
The Forcible mode is intended for testing involving forcing relay operation by test signal injection and verifying correct
relay output. This mode is also for tests to verify the relay outputs (both contact and communications) have the intended
impact on specific power system devices or on specific other substation automation devices. Contact outputs can be
selectively enabled or forced as described in the following two sections. Shared outputs to bricks have their test mode flag
raised, which results in their value only being accepted by relays also in forcible mode. GOOSE transmissions have the
"simulation" flag set, which results in these only being accepted by other devices that have their "Sim" data attribute set.
The "Sim" data attribute in the relay is set, so that if GOOSE messages are received with the "simulation" flag set, these are
used in place of the normal messages. The quality attribute of values that are output via 61850 MMS services are set to
"valid" + "test," which signals that the values should not be used for operational purposes.
