Indirect addressing allows an automation program to create versatile software that can be reused on different machines and regardless of physical addressing and structures used. TIA Portal provides, in addition to the classic pointers Pointer and ANY, indirect addresses typical of C ++, such as Variant
and Reference.
The course enables participants to fully understand the use of arrays, structures and UDTs within the S7-1200 and S7-1500 CPUs. In particular, it is shown how it is possible to use this information with the use of the Variant and Reference pointers.
Objectives
After attending the course, you can:
Distinguish the different types of pointers present in the TIA Portal
Use pointers for simple handling of complex data
Integrate pointers into your programs to increase the performance of your automation system
