Reading Out/Saving Service Data - Siemens SIMATIC ET 200SP System Manual

Testing with the trace and logic analyzer function
The trace function is used to record the CPU tags, depending on the settable trigger
conditions. Tags are, for example, the drive parameters or system and user tags of a CPU.
The CPU saves the recordings. You can display and evaluate the recordings with STEP 7, if
necessary.
The trace function can be called from the CPU's folder in the project tree, under the name
"Traces".
Simulation
With STEP 7 you can run and test the hardware and software of the project in a simulated
environment. Start the simulation using the menu command "Online" > "Simulation" > "Start".
Reference
You can find more information on test functions in the STEP 7 online help.
Further information about testing with trace and logic analyzer functions is available in the
Function Manual Using the trace and logic analyzer function
(http://support.automation.siemens.com/WW/view/en/64897128).

Reading out/saving service data

Introduction
In addition to the contents of the diagnostics buffer, the service data contains a wide range of
extra information about the internal status of the CPU. If a problem occurs the CPU that
cannot be solved with other methods, send the service data to our Service & Support team.
The service data allows Service & Support to run fast analysis of the problems that have
occurred.
Requirement
You can read service data with:
● the Web server
● STEP 7
● SIMATIC memory card
Distributed I/O system
