Trip matrix logic TMAGGIO
Trip matrix logic TMAGGIO function is used to route trip
signals and other logical output signals to different output
contacts on the IED.
TMAGGIO output signals and the physical outputs allows the
user to adapt the signals to the physical tripping outputs
according to the specific application needs.
Configurable logic blocks
A number of logic blocks and timers are available for the user
to adapt the configuration to the specific application needs.
• OR function block.
• INVERTER function blocks that inverts the input signal.
• PULSETIMER function block can be used, for example, for
pulse extensions or limiting of operation of outputs, settable
pulse time.
• GATE function block is used for whether or not a signal
should be able to pass from the input to the output.
• XOR function block.
• LOOPDELAY function block used to delay the output signal
one execution cycle.
• TIMERSET function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a settable
time delay.
• AND function block.
• SRMEMORY function block is a flip-flop that can set or
reset an output from two inputs respectively. Each block
has two outputs where one is inverted. The memory setting
controls if the block's output should reset or return to the
state it was, after a power interruption. Set input has
priority.
• RSMEMORY function block is a flip-flop that can reset or
set an output from two inputs respectively. Each block has
two outputs where one is inverted. The memory setting
controls if the block's output should reset or return to the
state it was, after a power interruption. RESET input has
priority.
Extension logic package
The logic extension block package includes additional trip
matrix logic and configurable logic blocks.
Fixed signal function block
The Fixed signals function (FXDSIGN) generates a number of
pre-set (fixed) signals that can be used in the configuration of
an IED, either for forcing the unused inputs in other function
blocks to a certain level/value, or for creating certain logic.
12. Monitoring
Measurements CVMMXN, CMMXU, VNMMXU, VMMXU,
CMSQI, VMSQI
The measurement functions are used to get on-line
information from the IED. These service values make it
possible to display on-line information on the local HMI and
on the Substation automation system about:
• measured voltages, currents, frequency, active, reactive
and apparent power and power factor
• primary and secondary phasors
• positive, negative and zero sequence currents and
voltages
• mA, input currents
• pulse counters
Supervision of mA input signals
The main purpose of the function is to measure and process
signals from different measuring transducers. Many devices
used in process control represent various parameters such as
frequency, temperature and DC battery voltage as low current
values, usually in the range 4-20 mA or 0-20 mA.
Alarm limits can be set and used as triggers, e.g. to generate
trip or alarm signals.
The function requires that the IED is equipped with the mA
input module.
Event counter CNTGGIO
Event counter (CNTGGIO) has six counters which are used for
storing the number of times each counter input has been
activated.
Disturbance report DRPRDRE
Complete and reliable information about disturbances in the
primary and/or in the secondary system together with
continuous event-logging is accomplished by the disturbance
report functionality.
Disturbance report DRPRDRE, always included in the IED,
acquires sampled data of all selected analog input and binary
signals connected to the function block with a, maximum of
40 analog and 96 binary signals.
The Disturbance report functionality is a common name for
several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
• Fault locator
The Disturbance report function is characterized by great
flexibility regarding configuration, starting conditions,
recording times, and large storage capacity.
