Explanation
Data unit, representing a sequence of 8 bits; without a plus/minus sign,
if not specified
Common Industrial Protocol
Controller from the samosPRO COMPACT product family
Cyclic Redundancy Check, a type or the result of a hash function for
revealing errors in the area of data storage or transmission
A data block contains 2-12 bytes of the relevant data set (depending on
the gateway used).
Describes a quantity of associated data, e.g. logic values or system state
data. A data set can consist of several data blocks.
Input/output
Encoded Path, especially for CIP applications
Industrially-used Ethernet network, combines standard Ethernet tech-
nologies with CIP
Connection module for industrially-used networks, such as EtherNet/IP,
PROFIBUS DB, CANopen, Modbus TCP, etc.
An identifier or an identity
The physical representation of an object within a class. It stands for one
of several objects within the same object class. (Reference: CIP specifi-
cation, version 3.18)
Internet protocol
A series of objects representing a similar system component. A class is a
generalization of the object, a template for defining variables and
methods. All the objects within a class are identical with regard to func-
tion and behavior. However, they may have differing attribute values.
(Reference: CIP specification, version 3.18)
Low Significant Byte
Measured Packet Interval; shows the API at the time of measurement
Most Significant Byte
Originator to Target (sender to target device)
Open Device Vendor Association
Personal Computer
Programmable Controller Communication Command
Programmable Logic Controller
Requested Packet Interval
Receive
Serial number
Configuration software for controller modules of type SP-COP. The
software can be run on a PC and communicates with the controller
modules.
Service to be performed
Examples: GetAttributeSingle, SetAttributeSingle
Data type specified for CIP devices; stands for a character string (1 byte
per character, 1 byte length code)
Short integer = 1 byte
Safety controller consisting of a controller module of the samosPRO
COMPACT product family, as well as optionally connectable expansion
gateways and I/O modules.
