TOF Timer used in SCL

I want to use TOF (SFB5) timer in function block based on SCL coding. I wrote the code in SCL source file. To add SFB5 in code I go through the following methods.

1. I took a SFB5 from my CPU by going online and drag and drop this function in to my project.

2. then I update the symbol table to define SFB5

3. then I used this in my SCL source file but after compilation it is giving the error ( Non-exixtent function or missing instance declaration.)

4. Same way I have used TON timer and it is working well, then What is the problem with the TOF here?

Please help into this.

please find the attached photo.

Try adding it to your project this way. There might be some other SFB it needs to call to operate. on the menu choose insert/block call

Thanks for reply.

But i did not find the option "block call" in insert menu toolbar. please find attached photo.

Thanks again. I found it. now issue resolved.
