Logic
Under the Logic function folder there is viewable data for trip logic (showing number
of poles that have tripped and trip signal information), event counter values, Logic
gate outputs, Logic SR memory output states and Logic timer set output states are
also shown here.
11.6.13.1
Tripping logic (PTRC, 94)
Test/Function status/Logic/TripLogic(PTRC)
Displays up to five instances of the function (TRP) with eight measurements per
instance. The output data from each measurement is boolean and indicates the
existence of various trip signals. For example, if the output from parameter TRL1 is
one, this indicates that a trip signal from phase L1 has been generated.
11.6.13.2
Event counter
Test/Function status/Logic/Event counter/CNTx
There are five instances of CNTx presenting 6 output values each.
11.6.13.3
Trip matrix logic (GGIO, 94X)
Test/Function status/Logic/TripMatrix(GGIO)
Displays up to 12 instances of the function (TRO) with 3 boolean output values per
instance. The output signals from this function block are typically connected to other
logic blocks or directly to IED output contacts.
11.6.13.4
Logic gate
Test/Function status/Logic/LogicGate
Displays 40 instances of the gate output. The output data type is an integer with a
possible value from 0 to 255.
11.6.13.5
Logic pulse timer
Test/Function status/Logic/LogicPulseTimer
Displays one value in boolean form indicating output from the pulse timer.
11.6.13.6
Logic SR memory
Test/Function status/Logic/LogicSRMemory
Displays 40 instances of the function (SM). There are two measurement parameters
per instance, SMnn OUT (Output) and SMnn N_OUT (Output inverted). The output
