Hi all,

We are using the FB ITL_SNTP_Client_3 from the IT_LIBRARY_11 library (

This FB is really handy when it comes to NTP synchronize a AXC F 2152.

Yet, we face the following problem.

When sending request to a specific NTP server we are able to freeze the FB completely. Essentially, we trigger multiple request to the server and the FB end up with a KissOfDeath code and remains completely frozen.

This kind of error should indeed be handled but we do not know how to unfreeze the FB after such event.

You can find a screenshot of the FB attached to this message.

Looking at the change log of the library it really sounds like the same issue fix between the version 3 and 4: Stuck in state 997 in case of error.

Has anyone encounter the same issue or know how we could get some help from the Library author ?

Thanks for your help !

Have a nice day.

Hi Martin PLCnext Team

Thanks for your reply.

As suggested I sent a message to the Dev Team of the Library.

I hope we will get an answer. Yet, maybe we could let the current post live a bit more... Maybe somebody will react on the subject :-)

Have a nice day.
