8.1 Overview
Diagnostic Options in STEP 7
STEP 7 provides you with a graded concept allowing you to query information
about the status of your SIMATIC S7 components and functions and to sort out
problems in a variety of different situations. These options cover the following:
 Hardware Diagnostics and Troubleshooting with STEP 7
Hardware diagnostics provides dynamic information on the operating mode of
modules including CPs when the S7 station is online.
You can recognize the existence of diagnostic information for a module by the
diagnostics icon in the project window of the SIMATIC Manager. Diagnostic
icons show the status of the corresponding module and also the operating
mode of CPUs.
Detailed diagnostic information is displayed in the “module information” that you
can open by double-clicking a diagnostic icon in the quick view or the diagnostic
view.
 Communication Diagnostics with NCM S7 Diagnostics
The NCM S7 Diagnostics described here provides dynamic information on the
operating state of the communication functions of online CPs or modules.
 HW Config Provides Static Information
Static information means the configured communication properties of an online
or offline CP and you can display this at any time using the hardware
configuration shown by HW Config.
What You Should Already Know
You should be familiar with the basic information in Chapter 2 on the significance of
NCM 7 and working with it. This means that you know how to connect the Ethernet
CP to the PG and how to control the module using the PG.
Where to Find Further Information
Further information is available from the following sources:
 Information about the communication services is available in the appropriate
chapters in this manual.
 When you are working with the diagnostic tool, the integrated help system
provides you with context-related support.
 You will find detailed information on working with STEP 7 programs in the Help
on STEP 7, which includes the topic “Diagnosing Hardware”.
