Glossary
Class 1 master
Active station on PROFIBUS DP. It is characteristically used for cyclic data exchange with
other stations. Typical Class 1 masters include PLCs with a PROFIBUS DP connection.
Class 2 master
Optional station on PROFIBUS DP. PC / PG are typical class 2 masters.
Configuration
Configuration is the systematic arrangement, setting, and networking of the individual
3RW5 soft starters within the device or network view.
Configuring
This section refers to the configuration and parameterization of 3RW5 soft starters.
Diagnostics
Data that is transferred from the 3RW5 soft starter and indicates the current operating status.
DP master
Cyclic send data is exchanged in a PROFIBUS DP system between the DP master and the
DP slave once in every DP cycle. The DP master sends the cyclic receive data to the
3RW5 soft starter. In response, the 3RW5 soft starter sends the cyclic send data to the DP
master.
DP slave
Slave operating on PROFIBUS with the PROFIBUS DP protocol.
DPV1 slave
DP slave that enables acyclic data exchange of parameter, diagnostic, receive and test data.
Fieldbus
Industrial communication system that connects a large number of field devices such as
probes (sensors), final controlling elements, and drives (actuators) to a control device.
