3.8.1 Function
(i) Mode sensor
The MDCTRL function can monitor the state change (On to TEST / TEST to Off) in the IED.
To use this monitoring function, On should be set for the scheme switch [MDCTRL-EN] prior to
operation. During the operation, a select signal and an operate signal are provided for the
TEST-FB when the SAS provides a test command for the IED; hence, the MDCTRL function
comes with two time-out timers. Setting [MDCTRL-SELRST] provides a time-out timer for
canceling a select command; setting [MDCTRL-EXERST] provides a time-out timer for
canceling an operate command.
(ii) Interface for IEC61850
The MDCTRL function can fulfil the two operation modes (On and Test) specified in the IEC
61850 communication, as shown in Table 3.8-2; the MDCTRL function can carry a signal for
changing for the TEST-FB; the signal is generated in the select and control logics in the
MDCTRL function. The change signal is initiated by the mode change command that is
received at the communication interface. Note that control operations from a SAS is only taken
account.

Definition in IEC 61850
1
On
The application represented by the LN works. All communication
services work and get updated values.
3
Test
The application represented by the LN works. All communication
services work and get updated values. Data objects will be transmitted
with quality “test”. Control commands with quality test will be
accepted only by LNs in “test” or “test-blocked” mode. “Processed as
valid” means that the application should react in the manner what is
foreseen for “test”.
(iii) Input signal from control hierarchy
Note PLC logic “Control hierarchy condition” is required to operate the MDCTRL function; the
user should notice that the connection with the Control hierarchy is made using the connection
point “MDCTRL01IN_TMP_28” (see Table 3.8-3). For more information, see chapter Control
and monitoring application: Control hierarchy .
