Programming IO controller
To program the sample program for the IO controller, follow these steps:
1. Using the SCL programming language, create a new function with the name "further
processing" in the project tree in "Program blocks" > "Add new block". Open the function.
2. In the interface of the function "further processing", create the following tags:
3. In the instruction window of the function "further processing", write the following program
code:
#output:=#result;
4. Call the function "further processing" in a program cycle OB, for example, in OB1.
5. Wire the function "further processing" in the program cycle OB as follows:
