Application Layer; Data Access Methods; Data Map - Siemens PROFIBUS DP-V1 Operating Instructions Manual

Application layer

This section describes the information that can be read and written to the MultiRanger
200 HMI or the HydroRanger 200 HMI.
The PLC reads data from the Read block (PLC input) of the PROFIBUS DP-V1 module.
Please note that the current firmware of the HydroRanger 200 HMI does not require a
Write block (PLC output) to be configured in the PLC, as cyclic writing to the MultiRanger
200 HMI is not supported at this time.

Data access methods

The PROFIBUS DP-V1 module supports cyclic and acyclic communications for Class 1 and
Class 2 master.

Data map

This section describes the read/write process data available from the MultiRanger 200
HMI or the HydroRanger 200 HMI. Please refer to the Parameters chapter of the your
Siemens device operating instructions for details about the parameters used in the table
below.
