What are the customer benefits?
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 process makes
sense if you write to the card often in your
application, for example if you use data logs.
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 indi-
vidual executed loops
• Use of breakpoints for program validation
also possible in SCL/STL networks within
LAD/FBD blocks
The PS 60W 24/48/60VDC HF enables extend-
ed retentivity of the CPU's data work memory.
In the event of failure of the supply voltage,
the PS 60W 24/48/60VDC HF supplies suffi-
cient power for the CPU to back up the entire
data work memory (without retentive data) to
the SIMATIC Memory Card.
For all applications that require the exact
time, you update the CPU time using the NTP
method. This also automatically sets the CPU
time beyond subnet limits.
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 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
easier.
