Performing Calibration Via Profibus Pa - Siemens SITRANS LR200 Instruction Manual

Performing calibration via PROFIBUS PA

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. (An Application Guide
SIMATIC PDM
is available on our website: www.siemens.com/processautomation.)
Changing parameter settings
• First launch SIMATIC PDM, connect to SITRANS LR 200, and upload data from the
device.
• Adjust parameter values in the parameter view field (right side of screen).
• After adjusting the value, press Enter (the status fields read Changed).
• When you have completed the adjustments, open the Device menu, download data
to the device, and save parameter settings offline (the status fields go blank).
