System overview
5.3 SIMATIC Drive Controller functions
Example: Trace optimizes the commissioning of packaging machines
Automation task:
At what speed does a plant reach its maximum productivity? How do you quickly determine
the optimum settings?
The packaging machine ensures quick and reliable packaging of ECG electrodes on a rotary
table which is loaded and unloaded by a conveyor belt.
Feature:
After filling, the issue is the correct time for further transport of the packages electrodes. To
this end, light barriers trace the position of the electrodes.
Solution:
The Trace function of a SIMATIC Drive Controller shows the exact sequence of selected
signals over a short period of time. It helps the start-up engineer find the exact light barrier
positions and the optimum speed for belts and the rotary table.
The trace recordings are supplied to the customer as part of the plant project. In the event of
a fault, the customer can see whether changes to the basic settings have caused the fault.
The trace recordings in the CPU trace can also be stored as a "measurement" on the SIMATIC
Memory Card; up to 999 trace recordings are available for evaluation.
Advantages
The Trace function provides the following advantages:
• A uniform standard for tag analysis that allows even sporadic errors to be located rapidly
• Cost-effective and easy evaluation as the signals are available in the CPU
• Monitoring of highly dynamic processes
• Cycle-by-cycle recording:
– Of up to 16 different signals and up to 8 separate trace jobs in the CPU trace
– Of up to 8 different signals and up to 2 separate trace jobs in the SINAMICS Integrated
• Storage of the CPU trace recordings in a separate memory area for easy localization of
sporadic errors
• Various trigger options
• Various zoom and cursor measuring functions
• Storage of CPU trace recordings on the SIMATIC Memory Card
• Trace recordings can be evaluated on the SIMATIC Memory Card over SIMATIC Drive
Controller Web servers
• Export of trace recordings, for example for user-specific processing
