14.5 Logic for group indication INDCALH
14.5.1 Identification
Function description
Logic for group indication
14.5.1.1 Application
Group indication logic function INDCALH is used to route indication signals to different LEDs and/or
output contacts on the IED.
INDCALH output signal IND and the physical outputs allows the user to adapt the indication signal to
physical outputs according to the specific application needs.
14.5.1.2 Setting guidelines
Operation: On or Off
14.6 Configurable logic blocks
The configurable logic blocks are available in two categories:
• Configurable logic blocks that do not propagate the time stamp and the quality of signals. They
do not have the suffix QT at the end of their function block name, for example, SRMEMORY.
These logic blocks are also available as part of an extension logic package with the same
number of instances.
• Configurable logic blocks that propagate the time stamp and the quality of signals. They have
the suffix QT at the end of their function block name, for example, SRMEMORYQT.
14.6.1 Application
A set of standard logic blocks, like AND, OR etc, and timers are available for adapting the IED
configuration to the specific application needs. Additional logic blocks that, beside the normal logical
function, have the capability to propagate timestamp and quality are also available. Those blocks
have a designation including the letters QT, like ANDQT, ORQT etc.
14.6.2 Setting guidelines
There are no settings for AND gates, OR gates, inverters or XOR gates as well as, for ANDQT gates,
ORQT gates or XORQT gates.
For normal On/Off delay and pulse timers the time delays and pulse lengths are set from the local
HMI or via the PST tool.
Both timers in the same logic block (the one delayed on pick-up and the one delayed on drop-out)
always have a common setting value.
For controllable gates, settable timers and SR flip-flops with memory, the setting parameters are
accessible via the local HMI or via the PST tool.
