LD Ladder Diagram
One of the IEC1131-3 programming languages (language used
to define configurable automation).
LED Light Emitting Diode
LF
Low Frequency
LOC Local Operator Console dedicated to maintenance operation
Local / Remote Control
Mode
When set to local for a given control point it means that the
commands can be issued from this point, else in remote control
are issue for upper devices.

LV
Low Voltage
MAFS Marketing And Functional Specification
MC
Modular Computer
Measurements Values issued from digital inputs or analogue inputs (with value,
state and time tag).
Metering
(non-tariff)
Values computed depending on the values of digital or
analogue inputs during variable periods of time (time
integration).
Metering
(tariff)
Values computed depending on the values of digital or
analogue inputs during variable periods and dedicated to the
energy tariffication. These values are provided by dedicated
“ tariff computer ” which are external to the MiCOM Systems.
MIDOS
Schneider Electric Connector used for CT/VT acquisition
MMC Medium Modular Computer
ModBus
Communication protocol used on secondary networks with IED
or with SCADA RCP. 2 versions exist with standard MODICON
or Schneider Electric one.
Module
Word reserved in PACIS SCE for all electric HV devices. It
groups all switch-gears, transformer, motors, generators,
capacitors, …
MOTION Transient state of a Double Point
Occurs when the two associated digital inputs are momentarily
in state 0 (e.g. position indication when an electrical device is
switching ). The concept of “ momentarily” depends on a
user-selectable delay.
MPC
Protection Module for Computer
MV Medium Voltage
NBB Numerical Busbar Protection
NC
Normally Closed (for a relay)
NO Normally Open (for a relay)
OBS
One Box Solution
Computer which provides protection and control functions with
local HMI. The prime application of this device is intended for
use in substations up to distribution voltage levels, although it
may also be used as backup protection in transmission
substations. Likewise, the OBS may be applied to the MV part
of a HV substation which is being controlled by the same
substation control system.
