Analog and I/O modules

Overview

Under Analog modules in the General settings menu there are settings for Analog
inputs and I/O modules. Within each instance of analog input there are settings for
all 12 channels that include the name of the channel, star point of the CT circuit,
the primary and secondary values from the measuring transformers (CTs and VTs).
The channel type and ratings are shown but cannot be changed.
The settings for binary inputs and outputs even include the milliampere input
modules. A mix of up to 14 instances of BIM, BOM and IOM is possible
depending on the physical configuration of the IED. Operation ON or OFF can be
set for all of these and for the BIMs oscillation release and oscillation block
settings are available. These settings are on board level and apply to all binary
inputs or outputs on a board.

Analog modules

Main menu/Settings/General Settings/Analog modules/AnalogInputs
Displays all variations of analog input modules with parameters. The analog input
modules have different combinations of current and voltage inputs. Each channel
has parameters where the type of channel is set, the primary and secondary values
from VTs and CTs and for Current Transformers the star point location (line side
or busbar side) is set.
Main menu/Settings/General Settings/Analog modules/MergingUnit
Displays parameters for the merging units. For the MU channels, no primary or
secondary values need to be set, due to the fixed standardized scaling of 1 mA/10
mV per LSB
Main menu/Settings/General Settings/Analog modules/3PhaseAnalogGroup/
SMAIX:Y
Here, settings for the Fourier filters, the minimum system voltage required to
measure frequency, the item designation of CTs or VTs, and the system voltage are
set. These settings are required by the preprocessing blocks and are usually only
adjusted during the initial engineering phase.
