OLE Object Linking and Embedding
OLE is a Microsoft specification and defines standards for
interfacing objects.
OPC OLE for Process Control
OPC is a registered trademark of Microsoft, and is designed to
be a method to allow business management access to plant
floor data in a consistent manner.
Operation hours Sum of time periods, a primary device is running under carrying
energy, e.g. circuit breaker is in Close-state and the current is
unequal 0 A.
OSI Open System Interconnection
Split and define communication in 7 layers: physical, link,
network, transport, session, presentation, application
PLC
Programmable Logic Control
Within the PLC-programs are defined the configurable control
sequences or automations taken into account by the MiCOM
Systems.
POW
Point On Wave: Process to control the three poles of an HV-
circuit breaker in a way, to minimise the effects of switching.
PSTN Public Switched Telephone Network
PT100
Probes of temperatures providing analogue signals.
RCC
Remote Control Centre
Is a computer or system that is not part of MiCOM system. RCC
communicates with and supervises MiCOM system using a
protocol.
RCP
Remote Control Point
Name given to the device or part used to control remotely
several bay or sub-station. Usually associate with Remote/Local
sub-station control. It is a SCADA interface managed by the
MiCOM system through Telecontrol BUS. Several RCP’s can be
managed with different protocols.
Remote Control Mode When set for a given control point it means that the commands
are issued from an upper level and are not allowed from this
point.
Remote HMI Remote HMI is a client of the substation HMI server. The client
may provide all or part of functions handled by the substation
HMI.
RI Read Inhibit
This output indicates the availability of an analogue output (e.g.
during DAC converting time)
RRC
Rapid ReClosure
RSVC Relocatabled Static Var Compensator
RTU Remote Terminal Unit
Stand alone computer that acquires data and transmit them to
RCP or SCADA. Typically it is the C964. RTU link is the TBUS.
SAT
Site Acceptance Test
Validation procedures executed with the customer on the site.
