10.1.4 Expanded DP functions
The PROFIBUS standard has been expanded (DPV1) and, in addition to the cyclic services, also offers
acyclic services. These services operate in parallel with the cyclic user-data communication. Masters and
slaves can use additional READ and WRITE functions as well as ALARM functions. This is intended espe
-
cially for operation with an engineering tool (DP-master class 2, DPM2) in order to change parameters and
read out status information during normal operation.
The acyclic services operate with lower priority. The functions are different for the various master classes.

Services for DPVM1 class 1 and slaves
10.1.5 Automatic baud rate detection
The PROFIBUS implementation of the device features automatic baud rate detection. The device uses this
function and offers no possibility for manual or permanent adjustment. The following baud rates are
supported:
Table 10.4:
Baud rates
Automatic baud rate detection is indicated in the device master file of the device: Auto_Baud_supp = 1
10.2 Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the device.
Before connecting the supply voltage, recheck all connections and ensure that they have been properly
made.
The device is defined as a slave in device master file (GSD file) of the BCL 604i!
