Remote operation via PROFIBUS PA
SITRANS Probe LU (PROFIBUS PA) is a Class B, Profile Version 3.0, rev. 1, PA device. It
supports Class 1 Master for cyclic and acyclic data exchange, and Class 2 for acyclic
services. The full range of SITRANS Probe LU functions is available only over a
PROFIBUS PA network.
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com.
To use PROFIBUS PA, you will need a PC configuration tool: we recommend
SIMATIC PDM. Please consult the operating instructions or online help for details on
using SIMATIC PDM. (You can find more information at www.fielddevices.com: go to
Products and Solutions > Products and Systems > Process Device Manager.)
SIMATIC PDM
SIMATIC PDM is a software package used to design, parameterize, commission,
diagnose and maintain SITRANS Probe LU and other process devices.
SIMATIC PDM contains a simple process monitor of the process values, alarms, and
status signals of the device. SIMATIC PDM allows you to manage process device data in
the following ways:
•display
•set
•change
•compare
• check the plausibility
•manage
• simulate
Device Description
