Click "Load". 7. Confirm the "Start all" option and click "Finish".The "optimized data blocks" of the CPUs of the series are optimized for |
performance and are only programmed symbolically. By using the optimized data blocks,
you make your program more efficient, because the declared tags are given symbolic names
and no longer a fixed address.
You can create data blocks with any structure without paying attention to the physical
arrangement of the individual tags. Quick access to the optimized data is always available
because the data storage is optimized and managed by the system.
Changing data types increases the risk of error in the standard block. In the optimized block,
changes lead to a reorganization of the data storage. Addressing remains unique.
To enable the subsequent editing of user programs that are already running in a CPU, the
CPUs support the option of extending the interfaces of function or data blocks
during runtime. You can download the modified blocks without setting the CPU to STOP and
without affecting the actual values of tags already loaded.
In addition: You can define in the data block itself, which the values in the CPU are readIn the following section, you will supplement the "Filling" data block with the date and time of
the last filling and reload the data block. To do this, create a block for recording the date and
time and enable the function "Download without reinitialization".
Note: The "Download without reinitialization" function protects the actual parameters of the
data block from being overwritten during download to the CPU.
Advantages of symbolic addressing: The use of universally applied and meaningful symbols
in the entire project makes the program code easier to read and understand. This gives you
the following advantages:
● You do not have to write detailed comments.
● Data access is faster.
● No errors occur when accessing data.
● You no longer have to work with absolute addresses.
● The assignment of the symbol to the memory address is monitored by STEP 7, which
means that all points of use are automatically updated when the name or the address of a
tag changes.
Requirement
● The library has been loaded
● The project has been compiled and loaded into the CPUrograms in periodic time intervals independently of the cyclic program execution. The start
times of a cyclic interrupt OB are specified using the cycle time and the phase offset.
Cycle time
The cycle time determines the interval at which an OB is called. The cyclic interrupt OB has
a cycle time of 100000 μs by default.
Phase offset
The phase offset is used to increase the accuracy of the processing intervals of cyclic
interrupt programs. If an OB has the same or a common multiple clock pulse of another OB,
both can be operated at a precise interval by a phase offset.hts, buttons and switches.
