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.
Setting guidelines
Operation: Enabled or Disabled
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.
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.
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.
