8.8 Testing with TraceTool
8.8.1 Introduction - TraceTool
Using the TraceTool of S7T Config, you can trace and save the signals and values
of variables. The recorded data are helpful, for example, in the diagnosis of motion
sequences of machines and troubleshooting in user programs. For better
diagnosis, you can also assign defined setpoint values to variables by means of the
function generator, while recording the values of other variables at the same time.
You can display and edit recorded measurements in a diagram.
Overview of recordable variables and of the corresponding tools:
Object Tool Which variables can be logged?
Integrated technology TraceTool
S7T Config
• internal system variables
• Variables of technology objects; Actual/setpoint
values, actual velocity and position values of the axes
• Variables of the user program
The data are recorded according to the position controller
cycle.
SINAMICS drives TraceTool
S7T Config
internal variables of the drive such as current, torque etc.
Logging according to the internal drive cycle.
SIMODRIVE drives * Trace function
(SimoComU)
internal variables of the drive such as current, torque etc.
Logging according to the internal drive cycle.
MASTERDRIVES drives * Trace function
(DriveMonitor)
internal variables of the drive such as current, torque etc.
Logging according to the internal drive cycle.
* Refer to the description of the functionality in the relevant Online Help.
8.8.2 Trace for SINAMICS drives
In the "Trace" tab, define the recording and trigger conditions, and configure the
signals to be recorded. You can record the values for parameters of the selected
SINAMICS drive device. Only individual element variables can be recorded for
arrays and structures.
You can use the recording results to locate configuration errors, for example. To
check the input, incorrect parameters are colored red. You must change these
parameters before you download the settings to the PLC. Certain parameters are
grayed out or not shown at all, depending on the configuration.
This Trace functionality closely resembles that of the standard Trace for
S7T Config. The layout of the various fields and buttons is slightly different. Where
appropriate, any differences are mentioned in the sections below.
