Bay control REC650 2.2
Product version: 2.2
according to the specific application needs for settable pulse
or steady output.
Group alarm logic function ALMCALH
The group alarm logic function (ALMCALH) is used to route
several alarm signals to a common indication, LED and/or
contact, in the IED.
Group warning logic function WRNCALH
The group warning logic function (WRNCALH) is used to route
several warning signals to a common indication, LED and/or
contact, in the IED.
Group indication logic function INDCALH
The group indication logic function (INDCALH) is used to
route several indication signals to a common indication, LED
and/or contact, in the IED.
Basic configurable logic blocks
The basic configurable logic blocks do not propagate the time
stamp and quality of signals (have no suffix QT at the end of
their function name). A number of logic blocks and timers are
always available as basic for the user to adapt the
configuration to the specific application needs. The list below
shows a summary of the function blocks and their features.
These logic blocks are also available as part of an extension
logic package with the same number of instances.
• 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. One of the outputs is inverted.
• 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, after a power interruption, the flip-flop resets or
returns to the state it had before the power interruption.
The SET input has priority.
• TIMERSET function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a settable
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.
Configurable logic blocks Q/T
The configurable logic blocks QT propagate the time stamp
and the quality of the input signals (have suffix QT at the end
of their function name).
The function blocks assist the user to adapt the IEDs'
configuration to the specific application needs. The list below
shows a summary of the function blocks and their features.
• ANDQT AND function block. The function also
propagates the time stamp and the quality of input
signals. Each block has four inputs and two outputs
where one is inverted.
• INDCOMBSPQT combines single input signals to group
signal. Single position input is copied to value part of
SP_OUT output. TIME input is copied to time part of
SP_OUT output. Quality input bits are copied to the
corresponding quality part of SP_OUT output.
• INDEXTSPQT extracts individual signals from a group
signal input. The value part of single position input is
copied to SI_OUT output. The time part of single
position input is copied to TIME output. The quality bits
in the common part and the indication part of inputs
signal are copied to the corresponding quality output.
• INVALIDQT function which sets quality invalid of outputs
according to a "valid" input. Inputs are copied to
outputs. If input VALID is 0, or if its quality invalid bit is
set, all outputs invalid quality bit will be set to invalid.
The time stamp of an output will be set to the latest time
stamp of INPUT and VALID inputs.
• INVERTERQT function block that inverts the input signal
and propagates the time stamp and the quality of the
input signal.
• ORQT OR function block that also propagates the time
stamp and the quality of the input signals. Each block
has six inputs and two outputs where one is inverted.
