command is not identical to “IED test status”.

Note: The “Event suppression” function can detect chattering in BI circuits. (See section
4.8.6(i)-3)
7
Note: A supervision of the Binary IO module can detect connection errors for BI circuits.
8
Note: The Common control (CMNCTRL) function can test and check the operation-
direction of logic. When the user sets Off for scheme switch [SCDEN], operation of
the logic is blocked if the logic is running in the same operation-direction
compared with the previous operation-direction. Alternatively, if On is set for the
scheme switch, the logic is not blocked.

Note: The user must program the PLC logic “Control hierarchy condition”. The user
must connect the “Control hierarchy condition” to the select condition logic using
the connection point “DPOS01IN_TMP_28”. For more information, see Chapter
Control and monitoring application: Control hierarchy
. See PLC#3 of Table
4.8-7.Note that the logic outputs are generated separately for both On and Off.
(viii) Signal name and number
Note: The user should note the meaning of the following descriptions as shown in
column “M/O” of each table:
“O” indicates that the signal is provided for optional use.
“M” indicated that the user should map/set/configure the signal; otherwise, the
user experience an operational failure if the default settings are used.
“N/A” indicates that that the user cannot change the state of the signal.
