16 Glossary
Acknowledge
Acknowledgment of a signal received.
Active metal component
Conductor or conducting component that is electrically live during operation.
Address
Identification number of, e.g. a memory position, a system or a module within a network.
Addressing
Allocation or setting of an address, e. g. for a module in a network.
Analog
Infinitely variable value, e. g. voltage. The value of an analog signal can take on any value, within certain limits.
Attribute
Attributes represent the data that a device makes available via the DeviceNet fieldbus (e. g. status of an object,
serial number of the device, process data).
Automation device
A device connected to a technical process with inputs and outputs for control. Programmable logic controllers
(PLC) are a special group of automation devices.
Baud
Baud is a measure for the transmission speed of data. 1 Baud corresponds to the transmission of one bit per
second (Bit/s).
Baud rate
Unit of measurement for data transmission speeds in Bit/s.
Bidirectional
Working in both directions.
Bit Strobe
A Bit Strobe I/O connection is a connection between a DeviceNet client and an undetermined number of servers,
these being queried by commands sent by the client.
Bonding strap
Flexible conductor, normally braided, that joins inactive components, e. g. the door of a switch gear cabinet to the
cabinet main body.
Bus
Bus system for data exchange, e. g. between CPU, memory and I/O levels. A bus can consist of several parallel
cables for data transmission, addressing, control and power supply.
Bus cycle time
Time required for a master to serve all slaves or stations in a bus system, i. e. reading inputs and writing outputs.
