Monitoring; Group Alarm Logic Function Almcalh; Group Warning Logic Function Wrncalh; Fixed Signal Function Block - ABB RET670 Product Manual

Transformer protection RET670 2.0
Product version: 2.0
Trip matrix logic TMAGAPC
Trip matrix logic TMAGAPC function is used to route trip signals
and other logical output signals to different output contacts on
the IED.
The trip matrix logic function has 3 output signals and these
outputs can be connected to physical tripping outputs
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.
Extension logic package
The logic extension block package includes additional trip
matrix logic and configurable logic blocks.
Logic rotating switch for function selection and LHMI
presentation SLGAPC
The logic rotating switch for function selection and LHMI
presentation SLGAPC (or the selector switch function block) is
used to get an enhanced selector switch functionality
compared to the one provided by a hardware selector switch.
Hardware selector switches are used extensively by utilities, in
order to have different functions operating on pre-set values.
Hardware switches are however sources for maintenance
issues, lower system reliability and an extended purchase
portfolio. The selector switch function eliminates all these
problems.
Selector mini switch VSGAPC
The Selector mini switch VSGAPC function block is a
multipurpose function used for a variety of applications, as a
general purpose switch.
VSGAPC can be controlled from the menu or from a symbol on
the single line diagram (SLD) on the local HMI.

Fixed signal function block

The Fixed signals function FXDSIGN generates 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.

Elapsed time integrator with limit transgression and overflow
supervision (TEIGAPC)
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 16 to Integer conversion with logic node
representation BTIGAPC
Boolean 16 to integer conversion with logic node
representation function BTIGAPC is used to transform a set of
16 binary (logical) signals into an integer. The block input will
freeze the output at the last value.
BTIGAPC can receive remote values via IEC 61850 depending
on the operator position input (PSTO).
Integer to Boolean 16 conversion IB16
Integer to boolean 16 conversion function IB16 is used to
transform an integer into a set of 16 binary (logical) signals.
Integer to Boolean 16 conversion with logic node
representation ITBGAPC
Integer to boolean conversion with logic node representation
function ITBGAPC is used to transform an integer which is
transmitted over IEC 61850 and received by the function to 16
binary coded (logic) output signals.
ITBGAPC function can only receive remote values over IEC
61850 when the R/L (Remote/Local) push button on the front
HMI, indicates that the control mode for the operator is in
position R (Remote i.e. the LED adjacent to R is lit ), and the
corresponding signal is connected to the input PSTO ITBGAPC
function block. The input BLOCK will freeze the output at the
last received value and blocks new integer values to be received
and converted to binary coded outputs.

13. 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:
