Good evening at all,
i'm stuck on the assignment of the IP and the PORT in the ID data at the SUBSCRIBE_COUNT and PUBLISH_COUNT FBs in the second step of the tutorial because, when i replicate the same step the tutorial did, in 4DIAC IDE will appear a warning saying that "a WSTRING litteral is sorrunded by double quotes" " even if in the tutorial the same value is written in the DATA variable is without double quotes and they say that will work.
I implemented the double quotes but the counting part (the new block i add in this step) doesn't work.
Could anyone help me understanding why am i doing wrong? i share the image of the problem for a better understandingì.
Thanks to all who will answer and have a good night

Nicolò

Hi,

I'm sorry but since writing the tutorial 4diac IDE got stricter in checking for correct literals. We will need this for upcoming features. Therefore now for all STRING literals single quotes and for all WSTRING literals double quotes are needed.

Unfortunately with the information you provided I'm not sure what is wrong. Have you tried turning monitoring on and watch the in and outputs of your function blocks? What does the deployment console say when you deploy your application.

Cheers,
Alois

Good evening Mr.: Zoitl,

Thank you for the explanation of the difference between STRING and WSTRING.

Cheers,
