Explanation
Data unit, representing a sequence of 8 bits; without a plus/minus sign, if not
specified
Common Industrial Protocol
Controller from the MSI 400 product family
Cyclic Redundancy Check, a type or the result of a hash function for reveal-
ing 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 technologies
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 specification,
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 function and beha-
vior. However, they may have differing attribute values. (Reference: CIP spe-
cification, 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 MSI 4xx. 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
