Nice tutorial for this function block. Do you have a tutorial for modifing a source of a finction block?

Hello mr. Tohid. İ have a little question. İ added oscat library and used some functions in it. İ got an error about there other libraries exist that using the same name. İ think there is a collision with standart library. One other thing is, that i have a modbus tcp slave device. And i can not delete its libraries. Could you tell me how can i fix this ?. İ need this error to go

Merhaba Taylan, I have faced the issue with the conflicting libraries in past but right now don't recall how I fixed it. I would suggest you join the Facebook group and ask your questions there. There will be more people to assist.

Thanks Tohid. This video was very useful for me! One question, what if write operation exceeds fifo size? must reset operation be programmed or the function block allows overwriting?

Hi Jesus. I am not sure about that. Need to double check. Let us know if you already have figured it out.

In this function block able to use only DWORD data type. How I can create the FIFO for REAL or STRING data types?

Just download the OSCAT FIFO16 sourcecode and adjust it's container type. SCL doesn't support Template types. So for every data type you can create your own FIFO buffer. Just adjust the sourcecode.
