Overview

PROFIBUS connection
The PROFIBUS connection allows connection to both a class 1 master (e.g. SIMATIC S7)
for cyclic communication of measured values and status and to a class 2 master (e.g.
SIMATIC PDM) for acyclic transmission of parameters.
The device master file "SIEM8115.gsd" is available for integration and configuration of the
SITRANS DA in a PROFIBUS network. It describes all the required information for cyclic
communication (particularly supported baud rates, number of input/output bytes including
consistency) with a class 1 PROFIBUS master (e.g. SIMATIC S7).
Integrating the device master file (GSD) into a planning tool (e.g. SIMATIC STEP 7, HW-
Config) facilitates simple and fault-free commissioning. The selected module structure allows
the user to adapt the type and quantity of communication data to the specific application.
This allows the bus and CPU loads to be influenced accordingly.
One of the modules described below must be selected during planning.
