Variant Data Type In Tia Portal Example Of Using Reference 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. Example of using variant data type to pass user defined data to function in siemens tia portal v18. in example we are using reference instructions: tia portal pointer.
Variant Data Type In Tia Portal Example Of Using Reference The variant data type is a special data type that accepts almost anything. similar to the any data type, tia portal essentially creates a pointer to the data and passes that, but with a few extra elements:. 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. 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. This document provides an example of using variants in tia v13 with an s71500 plc to process different step types in different ways by calling the same execution function.

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. Each instruction parameter supports at least one data type, and some parameters support multiple data types. hold the cursor over the parameter field of an instruction to see which data types are supported for a given parameter. The state parameter is of the data type variant and the status information is output as a bit character string. fig. 2 shows an example of how the two instructions can be parameterized. 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.
