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 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 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
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
made easier.
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.
You are given information on fast firmware
updates via accessible devices in the net-
work.
