Hi @Nishit ,  
thanks for new post!  
You are right we don’t have a settings to configure UDP protocol but we have a standard library [AsUDP](https://help.br-automation.com/#/en/4/libraries%2Fasudp%2Fasudp.html) (available for AS 4.x and 6.x) that contains FBKs for exchanging data packets via datagram sockets (UDP).

I see we have very cool public prjs on githuh for UDP, 2 for example:

1. [developsessions/b-r-udp-broadcast: B&R Automation Studio and Visual Studio projects to send a udp broadcast and receive the answers of the plc clients.](https://github.com/developsessions/b-r-udp-broadcast)

2. [hilch/demo-AsTcp-AsUdp: B&R Automation Studio demo: how to use AsTcp and AsUdp](https://github.com/hilch/demo-AsTcp-AsUdp) developed by @christoph.hilchenbac

I hope it helps
