6.1 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:
SHardware 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.
SCommunication 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.
SHW 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 from Chapter 2 about handling
NCM S7. This means that you know how to connect the Ethernet CP to the PG
and how to control the module using the PG.
