Term Meaning
CIP Common Industrial Protocol
The Common Industrial Protocol is an application protocol used in automation
technology. It supports the transition between eldbuses and industrial Ethernet and
IP networks. This industrial protocol uses EtherNet/IP in the application layer as
interface between eldbus and control, I/O, etc.
DHCP Dynamic Host Conguration Protocol
DHCP allows a server to dynamically distribute IP address and conguration
information to clients. Normally, the DHCP server provides at least the following
basic information to the client:
- IP address
- Subnet mask
- Standard gateway
EDS Electronic Data Sheet
An EDS le is an external le that contains information for a module. It provides
necessary information for access to and change of congurable parameters of a
module.
Ethernet frame In each Ethernet frame (data package), there are addresses of transmitter (source)
and receiver (target). When a frame is received, the receiving unit of a receiving
station compares the MAC target address with its own MAC address. When the
addresses match, the receiving unit forwards the contents of the frame to a superior
layer. If they do not match, the frame is discarded.
EtherNet/IP Ethernet Industrial Protocol
Open standard for industrial networks that supports both cyclic and acyclic transfer
of messages and uses standard Ethernet communication chips and physical media.
IO-Link
IOL
Standardized communication system to connect intelligent sensors and actuators to
an automation system
IP Internet Protocol
Protocol used for transferring data within a network, e.g. internet or intranet, from
one computer to another. Each computer in the network can be clearly identied by
means of its IP address. If data is sent from one computer to another, it is subdivided
into small information packages containing each transmitter and receiver addresses.
These packages can be sent over the network using di󰀨erent routes and arrive at
their destination in a di󰀨erent order than the sequence of sending. Another protocol,
the transmission control protocol [TCP], then restores the original order.
MAC address Media Access Control Address
Hardware address of network components used for clearly identifying devices in a
network.
ODVA ODVA is an international association for open and compatible information and
communication technologies in automation systems.
e.g., EtherNet/IP, DeviceNet, CompoNet and ControlNet, etc.
RPI Requested packet interval
The interval at which an EtherNet/IP target sends process data to the scanner.
