Glossary
GSD file
Information on the input and output range, as well as the consistency of the cyclically
transmitted data is defined in the GSD file (General Station Description or device master
data), tested with the configuration telegram from the device and, if appropriate, declared to
be valid. The GSD file is used for integrating the device into any DP standard master system
(automation system).
I&M data
Identification and maintenance data.
Information stored in a module that helps you to check the plant configuration, to locate
hardware modifications in a plant, or to remedy faults in a plant. I&M data enable modules to
be uniquely identified online.
Master
PROFIBUS DP is based on a master-slave architecture. Telegrams are sent by the master
to the addressed station (slave) and responded to by the slave.
Messages
Data that is transferred from the 3RW5 soft starter and indicates the current operating status.
Parameterization
Parameterization is the definition of parameters using the parameterization software.
PII/PIQ
Process image input/process image output
PROFIBUS
PROFIBUS stands for "process fieldbus". PROFIBUS is a manufacturer-independent
standard to network the field devices (e.g. PLCs, actuators, final controlling elements and
sensors). PROFIBUS is compatible with protocols such as DP (decentralized peripherals),
FMS (fieldbus message specification) and PA (process automation).
Reading data
Data are transferred from the 3RW5 soft starter.
In STEP 7, you can read the data sets as follows:
● S7 master: By calling SFC 59
● S7-DPV1 master: by calling SFB 52 "RD_REC" or SFC 59
