Process control systems usually feature integrated data acquisition (trending) with relatively slow cycle times of 50 ms or more. In addition, examination of the collected data for troubleshooting and process analysis is often insufficiently supported in trending. However, high-cycle, ideally cycle-precise, continuous recording of measured values is required to detect sporadic disturbances and programming errors in the CPUs. A convenient measured data acquisition system is provided by ibaPDA . The measured data collected in this way can be subsequently analyzed offline with the high-performance ibaAnalyzer.

ibaPDA

ibaPDA is a software package for measured data acquisition on a separate recording computer (PC). This measured data acquisition system offers various options for high-cycle acquisition of data from the SIMATIC world, e.g.

• Cycle-precise coupling of data via bus monitors, e.g. ibaBM‑DP (PROFIBUS bus monitor)), ibaBM-PN (PROFINET bus monitor) or via CP 1616 (PROFINET connection)
• Software-based interfaces, e.g. ibaPDA-Interface-PLC-Xplorer for communication with the CPUs of the automation systems via MPI, CP/PG or Ethernet-TCP/IP interface

Due to the various interfaces to a wide variety of automation and bus systems, higher-level data acquisition with uniform acquisition time can also be realized in systems with heterogeneous automation technology.

Using a recording computer, digital and/or analog signals can be recorded at rate down to 1 ms, or even down to 10 µs when the appropriate hardware is used.

On the recording computer, the measured data can be accessed and selected online with ibaPDA-Request-S7 without having to re-program or shut down the CPU of the automation system.

ibaAnalyzer

The signals recorded centrally with ibaPDA are stored in files and can be analyzed from any number of workstations using the freeibaAnalyzer software package.

The supplementary ibaAnalyzer-DB package permits the user-friendly further processing of the recorded data with database support. Recorded data can be written to various databases (e.g. Microsoft SQL Server, Microsoft Access, Oracle) and read again according to selectable query criteria.

Note:

ibaPDA and ibaAnalyzer can be used together with SIMATIC PCS 7 V7.1, V8.0, V8.1 and V8.2.
