What are the customer benefits?
Where can I find information?
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 makes sense in
particular if you write to the card often in your
application, for example if you use 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

Reading out the identification
and maintenance data using
the Get_IM_Data instruction
With the Get_IM_Data instruction you can
read out the identification and maintenance
data of the modules without much program-
ming work.
With the Get_IM_Data instruction, you can
access the identification and maintenance
data (I&M) of a module in the user program.
I&M data is information saved in a module.
This allows you to
• check the system configurations
• react to hardware changes
• react to hardware faults in the user pro-
gram.
Finding and elimination of hardware errors is

Time synchronization For all applications that need the exact time,
you update the CPU time using the NTP
process. This also automatically sets the
CPU time beyond subnet limits.
