Monitoring and Diagnostics of Control Valves using the “VlvMon” Function Block in SIMATIC PCS 7

  • Entry
  • Associated product(s)

Objective of this entry
The objective is performance monitoring and diagnostics of centrifugal pumps in the context of SIMATIC PCS 7 Plant Asset Management. A low-cost solution can be achieved by intelligent combination and logical interpretation of measured process values which are (mostly) already available in the DCS, in contrast to high-end condition monitoring systems based on dedicated additional sensors, e.g. vibration sensors or structure-borne sound sensors.

Main contents
The following issues are discussed in the document:

  • How to implement valve monitoring.
  • How to parameterize and commission valve monitoring.
  • How to evaluate the monitoring results in the context of plant asset management.

The VlvMon function block is part of the Condition Monitoring Library since PCS 7 V8.0.
