SITRANS LR 200 and SIMATIC PDM
Connecting SITRANS LR 200 to SIMATIC PDM using HARTmodem
Objective: • Become familiar with the SITRANS LR 200 wiring requirements and HART modem
• Become familiar with SIMATIC PDM configuration tool
Equipment: • SITRANS LR 200 instrument
• SITRANS LR 200 instruction manual
• SIMATIC PDM ver. 5.2 (SP. 1)
• HART modem interface
• Terminal screwdriver
• PC or Laptop
While every effort was made to verify the following information, no warranty of accuracy or usability is expressed or implied.
Overview:
SIMATIC PDM is the Siemens configuration software used to set up the SITRANS LR 200. All parameters are accessed through
PDM and projects containing configuration data are saved. SIMATIC PDM also provides diagnostic information, permitting the
user to view echo profiles and check set points.
To ensure that SIMATIC PDM connects properly, please complete the two processes outlined in Initial Setup:
• Updating the Device Description
• De-activating Buffers
This Application Guide discusses the following
• setting up SIMATIC PDM
• setting up a HART network
• adding the SITRANS LR 200 HART to a project
• viewing and editing parameters
• using SIMATIC PDM LifeList for quick access
