(UDP TCP Netcontroller)
Environment
- ACX5720
- ACX5740
- CX9702
- bCX9640
Cause
What transport type should be used when setting up an ACX57xx, CX9702, or bCX9640?
Resolution
The definition on the transport type settings from our Technical Reference Guide states that:
UDP - This controller will communicate with other controllers and Workstations primarily using the UDP protocol.
TCP - This controller will communicate with other controllers and Workstations primarily using the TCP protocol.
TCP/UDP - This controller will communicate with other controllers and Workstations primarily using the TCP protocol, but can also speak to controllers and Workstations that communicate primarily using the UDP protocol.
You can set the controller to use either or both transport types for communication with other devices depending on your specific network requirements. UDP is the preferred option for Continuum devices. See the Andover Continuum Network Ports document for details on what specific ports are required.
Three things you need to be aware of with this:
- Make sure that both the transport setting in the device object and the controllers IE configuration webpage are the same.
- No matter what transport type you choose make sure that any network firewalls are setup to allow packets through on those ports.
- View this document for some reasons to use Continuum's reliability layer over UDP rather than TCP.
