  • We successfully captured POWERLINK traffic using Wireshark.

  • The traffic capture was done via Ethernet port 2 of the X20BC0083 module.

  • Now, We wanted to specifically observed traffic on UDP port 3819, how it is enabling (Help me this)

  1. However, we need clarification on a few open points related to asynchronous communication

  2. ASnd / Asynchronous Communication Channel
    In our current Automation Studio setup 4.12.6.106 and 6.1.1.14, we do not see any option to:

    • Enable Asynchronous Communication Mode

    • Configure ASnd channel parameters

    • Enable or configure ASnd (Asynchronous Send) objects

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 (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.

  2. hilch/demo-AsTcp-AsUdp: B&R Automation Studio demo: how to use AsTcp and AsUdp developed by @christoph.hilchenbac
