Overview

One of the special features of SIPART PS2 is the option of communicating via PROFIBUS PA, FOUNDATION fieldbus or HART protocol. That guarantees a convenient exchange of information between the positioner and the higher-level system. The most comprehensive access to the broad diagnostic functionality of SIPART PS2 can be achieved via these communication lines. Supplementary trend values, histograms and commissioning/operating data stored in the SIPART PS2 can be clearly displayed and documented with the SIMATIC PDM tool via HART and PROFIBUS PA.

The SIPART PS2 has other features in addition to the option of transmitting the valve position by 4 – 20 mA signal or reporting via the processor that a valve has exceeded or fallen short of the position selected by the system operator. With a slot-type initiator or mechanical limit switch module, the positioner can redundantly detect the valve position independently of the electronics and transmit messages if a critical valve position is reached or the user requires reliable information on whether or not a valve is closed, for example.
