This Chapter helps you to get acquainted with tools you can use to carry out the
following tasks:
• Hardware/software error diagnostics.
• Elimination of hardware/software errors.
• Testing the hardware/software - for example, during commissioning.

It would go beyond the scope of this manual to provide detailed descriptions of all
the tools you can use for diagnostics, testing and troubleshooting functions.
Further notes are found in the relevant hardware/software manuals.

STEP 7 offers you the following testing functions you can also use for diagnostics:
• Monitoring and modifying of variables
Can be used for PG/PC monitoring of specific CPU or user program variables.
You can also declare permanent values for the variables.
• Testing with program status
You can test your program by viewing the program status of each function
(result of logical links, status bit) or the data of specific registers in real-time
mode.
For example, if you have selected the programming language LAD in STEP 7
for your presentation, the color of the symbol will indicate a closed switch or an
active circuit.
