The logic blocks are available as a part of an extension
logic package. The list below is a summary of the function
blocks and their features.
•
AND
function block. The AND function is used to form
general combinatory expressions with boolean variables.
The AND function block has up to four inputs and two
outputs.
•
GATE
function block is used for whether or not a signal
should be able to pass from the input to the output.
•
INVERTER
function block that inverts the input signal to
the output.
•
LLD
function block. Loop delay used to delay the output
signal one execution cycle.
•
OR
function block. The OR function is used to form
general combinatory expressions with boolean variables.
The OR function block has up to six inputs and two
outputs. One of the outputs is inverted.
•
PULSETIMER
function block can be used, for example,
for pulse extensions or limiting of operation of outputs,
settable pulse time.
•
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, after a power interruption, the flip-flop
resets or returns to the state it had before the power
interruption. RESET input has priority.
•
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. The SET
input has priority if both SET and RESET inputs are
operated simultaneously.
•
TIMERSET
function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a
settable time delay and must be On for the input signal to
activate the output with the appropriate time delay.
•
XOR
is used to generate combinatory expressions with
boolean variables. XOR has two inputs and two outputs.
One of the outputs is inverted. The output signal OUT is 1
if the input signals are different and 0 if they are the
same.
Fixed signal function block FXDSIGN
M15322-3 v15
The Fixed signals function (FXDSIGN) has nine 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.
Boolean, integer, floating point, string types of signals are
available.
One FXDSIGN function block is included in all IEDs.
Elapsed time integrator with limit transgression and
overflow supervision TEIGAPC
GUID-2D64874A-F266-4251-8EED-E813F40513D7 v3
The Elapsed time integrator function (TEIGAPC) is a
function that accumulates the elapsed time when a given
binary signal has been high.
The main features of TEIGAPC
• Applicable to long time integration (≤999 999.9 seconds).
• Supervision of limit transgression conditions and overflow.
• Possibility to define a warning or alarm with the resolution
of 10 milliseconds.
• Retaining of the integration value.
• Possibilities for blocking and reset.
• Reporting of the integrated time.
Boolean to integer conversion, 16 bit B16I
SEMOD175725-4 v5
Boolean to integer conversion, 16 bit (B16I) is used to
transform a set of 16 boolean (logical) signals into an
integer.
Boolean to integer conversion with logical node
representation, 16 bit BTIGAPC
SEMOD175781-4 v8
Boolean to integer conversion with logical node
representation, 16 bit (BTIGAPC) is used to transform a set
of 16 boolean (logical) signals into an integer. The block
input will freeze the output at the last value.
Integer to Boolean 16 conversion IB16A
SEMOD158373-5 v7
Integer to boolean 16 conversion function (IB16A) is used to
transform an integer into a set of 16 boolean (logical)
signals.
Integer to Boolean 16 conversion with logic node
representation IB16FCVB
SEMOD158421-5 v9
Integer to boolean conversion with logic node
representation function (IB16FCVB) is used to transform an
integer which is transmitted over IEC 61850 and received by
the function to 16 boolean (logic) output signals.
Comparator for integer inputs INTCOMP
GUID-A93564FA-0017-4939-A9C1-095DA0FD9832 v1
The function gives the possibility to monitor the level of
integer values in the system relative to each other or to a
fixed value. It is a basic arithmetic function that can be used
for monitoring, supervision, interlocking and other logics.
Comparator for real inputs REALCOMP
GUID-E17A88D7-D095-4F36-9CD5-64EBFD2A1DEA v1
The function gives the possibility to monitor the level of real
value signals in the system relative to each other or to a
fixed value. It is a basic arithmetic function that can be used
for monitoring, supervision, interlocking and other logics.
Hold Maximum and Minimum of Input HOLDMINMAX
GUID-7DA0AA9A-CCEA-4467-B67E-45B9C1DC145A v1
Hold minimum and maximum of input (HOLDMINMAX)
function will acquire, compare and hold the minimum and
maximum values of INPUT as soon as the START input
goes to 1, the outputs are updated as long as the START is
