Tia Portal Basics Working With Pointers Pdf You can read out the variant data type of a referenced tag during program runtime. in our example we use “typeof” instruction to query data type connected to input of our function. With variants, you can pass the structure for vsd 1 to your standard block, and the block will run a section of code for the vsd. when you pass vsd 2 to the same block, on the same pin, the block knows that it’s vsd 2 and runs a different section of code.
Tia Portal Defining Variables Plc Automation Consultancy Training The data type variant is typified, i.e., you can read out the data type of a referenced tag during program runtime. using the data type variant, you can above all create generic, standardized function blocks (fb) or functions (fc) for various data types. The data type variant can point to variables of different data types or parameters. the variant pointer can point to structures and individual structural components. Learning how to use siemens tia portal? this article demonstrates how to use variants with structures to create dynamic blocks that can handle different data sets. read on for my full explanation.

The 15xx 12xx cpu's use the "variant" datatype to pass on the send receive data while the et200s uses the "any" dataype. this is system cpu dependent according to siemens. In the plc world, siemens step7 (tia portal) has also introduced the concept of pointers. however, the pointer type in step7 differs slightly from that in c language, occupying 6 bytes, as illustrated below: among these, byte0 and byte1 are used to indicate the number of the data block (db). Understand how variant types affect pointer dereferencing in siemens s7 plc programming, including the use of udts, memory overlays, and the responsibility of the programmer to ensure correct interpretation. Pointers are used to reference data without containing it directly. they point to a starting location and length of data. pointers are created automatically for complex data types like arrays or structures. blkmov must be used to access pointer data instead of move.
