Logging Process Values and Alarms with WinCC (TIA Portal)
Siemens offers several products and solutions for logging process values and alarms.
Example: GMP data collection (logging of user actions)
The objective of this application example is to help you find the logging concept that best suits your requirements and, resulting from this concept, …
- determine the hardware.
- achieve optimum performance.
- provide the greatest possible security in terms of "access protection".
- ensure output/evaluation.
The application example provides a selection aid for the different logging concepts. This allows you to develop a concept/solution before the actual configuration of logs.
In addition, the application example describes the following program examples.
- Data log access via Miniweb
Using the example of a Comfort Panel, the document shows how to externally access the Comfort Panel's memory card with the stored data logs.
- Evaluation of a data log
The CSV file is evaluated by importing the data into an "Excel template".
Then the data can be output using an automatically generated "trend chart".
- Logging STRING tags
The tags are logged with the aid of a script or as "discrete alarms".
- Reading out the data of an RDB log
The data of an RDB log is read out and displayed using an Excel spreadsheet.
