ABBREVIATIONS
Slave Controller – Technology I-XVII
OPB
On-Chip Peripheral Bus
Optional Service
Optional services can be fulfilled by a PROFINET station in addition to the
mandatory services.
OSI
Open System Interconnect
OUI
Organizationally Unique Identifier –the first 3 Bytes of an Ethernet-Address that
will be assign to companies or organizations and can be used for protocol
identifiers as well (e.g. LLDP)
PDI
Process Data Interface or Physical Device Interface: an interface that allows
access to ESC from the process side.
PDO
Process Data Object
PDU
Protocol Data Unit: Contains protocol information (Src Addr, Dest Addr,
Checksum and service parameter information) transferred from a protocol
instance of transparent data to a subordinate level (the lower level contains the
information being transferred).
PE
Protection Earth
PHY
Physical layer device that converts data from the Ethernet controller to electric
or optical signals.
Ping
Frame that verifies whether the partner device is still available.
PLB
Processor Local Bus
PLL
Phase Locked Loop
PREOP
Pre-Operational state of EtherCAT state machine
Priority Tagging
Priority field inserted in an Ethernet frame.
Protocol
Rules for sequences – here, also the sequences (defined in state machines)
and frame structures (described in encoding) of communication processes.
Provider
Device that sends data to other consumers in the form of a broadcast message.
PTP
Precision Time Protocol in accordance with IEEE 1588: Precise time
synchronization procedures.
PTP Master
Indicates time in a segment.
PTP Slave
Station synchronized by a PTP master.
Quad Cable
Cable type in which the two cable pairs are twisted together. This strengthens
the electromagnetic resistance.
RAM
Random Access Memory. ESC have User RAM and Process Data RAM.
Read
Service enabling read access to an I/O device.
Real-Time
Real-time capability of a system to perform a task within a specific time.
Request
Call of a service in the sender/client.
Response
Response to a service on the client side.
