Password provider
As an alternative to manual entry of pass-
word, you can connect a password provider
to STEP 7. A password provider offers you
the following advantages:
•
More convenient handling of passwords.
STEP 7 automatically imports the pass-
word for the blocks. This saves you time
•
Optimum block protection as the users do
not know the password themselves

GetSMCinfo instruction
With the help of the GetSMCinfo instruction
you can respond to information provided by
the memory card in the user program and if
required, replace the memory card as a pre-
cautionary measure. This is particularly useful
if you frequently write data to the card in your
application, e.g. when using data logs.

Testing with breakpoints
When testing with breakpoints, you execute a
program from one breakpoint to another.
Testing with breakpoints provides you with
the following advantages:
•
Testing SCL and STL program code with
the help of breakpoints
•
Localization of logic errors step by step
•
Simple and quick analysis of complex
programs prior to actual commissioning
•
Recording of current values within individ-
ual executed loops
•
Use of breakpoints for program validation
also possible in SCL/STL networks within
LAD/FBD blocks
