What are the customer benefits?
When there is a connection to an existing
CPU, you can use the "Hardware detection"
function to read the configuration of the CPU
and apply the configuration in your project.
Thanks to the automatic import of the hard-
ware configuration, you do not need to man-
ually configure the CPU. This saves you time
and avoids input errors.
As an alternative to manual password entry,
you can link a password provider to STEP 7.
A password provider provides the following
advantages:
Convenient handling of passwords.
•
STEP 7 automatically reads in the pass-
word for the blocks. This saves you time
Optimal block protection because the
•
operators do not know the actual pass-
word
Using the GetSMCinfo instruction, you can
respond to information provided by the
memory card in the user program and, if
necessary, replace the memory card as a
precautionary measure. This makes sense in
particular if you write to the card often in your
application, for example if you use data logs.
When testing with breakpoints, you run a
program from breakpoint to breakpoint. Test-
ing with breakpoints offers the following ad-
vantages:
Testing SCL and STL program code using
•
breakpoints
Narrowing down logic errors step-by-step
•
Simple and rapid analysis of complex
•
programs before actual commissioning
Acquisition of actual values within individ-
•
ual loop passes
Utilization of breakpoints for program
•
validation also possible in SCL networks
with LAD / FBD possible
