the station bus. For that reason, test the function in a system, that is, either in a
complete delivery system as an acceptance test (FAT/SAT) or as parts of that system.
15.11.4 Single command SingleCommand16Signals
For the single command function block, it is necessary to configure the output
signal to corresponding binary output of the IED. The operation of the single
command function (SingleCommand16Signals) is then checked from the local
HMI by applying the commands with Mode = Off, Steady or Pulse, and by
observing the logic statuses of the corresponding binary output. Command control
functions included in the operation of different built-in functions must be tested at
the same time as their corresponding functions.

15.12.1 Tripping logic SMPPTRC
Prepare the IED for verification of settings outlined in section
"Overview" and
section "Preparing for test" in this chapter.
This function is functionality tested together with other protection functions (line
differential protection,earth-fault overcurrent protection, and so on) within the IED.
It is recommended that the function is tested together with the autorecloser
function, when built into the IED or when a separate external unit is used for
reclosing purposes. The instances of SMPPTRC are identical except for the name
of the function block SMPPTRC. The testing is preferably done in conjunction
with the protection system and autoreclosing function.
15.12.1.1 Three phase operating mode
1. Check that AutoLock and TripLockout are both set to Off.
2. Initiate a three-phase fault
An adequate time interval between the faults should be considered, to
overcome a reclaim time caused by the possible activation of the Autorecloser
function SMBRREC. The function must issue a three-phase trip in all cases,
when trip is initiated by any protection or some other built-in or external
function. The following functional output signals must always appear
simultaneously: TRIP, TRL1, TRL2, TRL3 and TR3P.
15.12.1.2 1ph/3ph operating mode
In addition to various other tests, the following tests should be performed. They
depend on the complete configuration of an IED:
