Hi,

I'm trying to use CPU clock in order to set some alarms. I've created a STL Source in Source container and I've copied AWL code provided by Siemens in other post.

Procedure

1. In the source container you generate a new "STL source" and open it.
2. Copy the source text (see below) for the conversion into either data type "String" (FUNCTION_STRING) or data type "Integer" (FUNCTION_INT) and change the number of the function block.
3. Insert the system function "SFC1" (Read System Clock) in the "CFC" and delete the system function again ("SFC1" is now in the block container Offline).
4. For conversion into the data type "String": Insert the function "FC16" (I_STRNG) in the "CFC" and delete the function again (the function is now in the block container Offline).
5. Compile the source.
6. Insert the function block in "CFC", compile and load the "CFC". Transfer your project to "WinCC".
7. Open a picture in the Graphics Designer.
8. Insert an object (an IO field, for example) and open the Object Properties (Mark IO field > Right-click > Properties).
9. Link the "Output value" property with the variable.

I don't know how to do step 3.

When I compile the source 2 errors appeared. You can see a picture attached.

Thanks for you response.

Thanks a lot

Hello,

Once I had SFC1(read_clk) compiled, I can't download because I have 1 error.

Picture attached.

Tanks for your response

Hello JLopezDOW,

you don't have to compile the CFC, when you have insert the SFC1.
Only copy from the library and deleted the block.

With regards
