I want report an error in the communication Publish/Subscribe in my distribuited application (on 3 device).
I explain the problem better.
1. I have to publish the event CONTATTA_ZONAA on 18.104.22.168:61341 (in the attachement ZonaB).
2. This event, published, isn't received from PRONTA_ZONAB in 22.214.171.124:61341 (in the attachement ZonaA). But socket status is ok.
So, I tried to change ip and port also but nothing good result.
3. So, I tried to receive this event on another device (in the attachement ZonaC_trial) on 126.96.36.199:61341 always, and it's ok there.
4. I tried to receive this event on the same device of Publish (in the attachement ZonaB_trial) on 188.8.131.52:61341, and it's ok there.
Thus, in my opinion, the problem is on the device ZonaA.
What could be the problem?

If possible, try to look the run time log or trace. There may be possibility of dropping the events since Forte is only capable of storing 254 events in it queue.|
Or else there may be a chance of Publish happening before the Subscribe function block getting initialized.
Other option that you could try out is complete all subscribe initialization after E_RESTART and then start you application by connection the last Subscribe function block INITO.
As suggested by Gerhard, you can try with "Trigger Event" also
