8.18 Trace

Result
Date and time are stored in the 3RW55 or 3RW55 Failsafe soft starter. When replacing the
3RW5 HMI High Feature, the date and time are retained in the 3RW55 or 3RW55 Failsafe soft
starter.
8.18 Trace
Operating principle
With the trace function (oscilloscope function), the 3RW55 and 3RW55 Failsafe soft starters can
be used as a kind of multichannel digital oscilloscope. The trace function enables you to record
data, events, measured values, etc. in any operating mode of the motor. The trace data must be
read out with the aid of the SIRIUS Soft Starter ES software (TIA Portal) from the 3RW55 or
3RW55 Failsafe soft starter. The trace data is visualized in the form of an oscillogram in the SIRIUS
Soft Starter ES (TIA Portal). With a 3RW5 HMI High Feature from firmware version V3.0, you
can save trace data on a micro SD card (Page 243).
Requirements
• SIRIUS Soft Starter ES (TIA Portal) Standard / Professional
Brief overview: Window "Project Navigation" with current project under created Soft Starter >
"Traces"
Types of trace
• Device trace
The recordings are saved on the 3RW55 or 3RW55 Failsafe soft starter and, when required,
can be read out and displayed as a graph using the SIRIUS Soft Starter ES (TIA Portal) software.
• Engineering trace
Recordings are read out cyclically using the SIRIUS Soft Starter ES (TIA Portal) software and
displayed as a graph.
Structure of trace data
• Trace configuration: The configuration defines which signals are to be recorded in the 3RW55
or 3RW55 Failsafe soft starter and how (trigger, recording pulse).
• Diagram: The diagram consists of the display options for the recorded data and - if the
recording has already taken place - the recorded data itself.
A diagram that contains the recorded data can be stored permanently in the project as a
measurement.
