Description

The Generic UDP interface can be used by every controller able to send UDP/IP messages. User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. The Generic UDP messages are IP Unicast messages sent from one or several controllers to the ibaPDA system using a defined port number. ibaPDA also supports UDP/IP multicast messages. Each UDP connection is precisely identified in ibaPDA by the destination "Port" and source of the "Address".

Up to 64 connections can be used per interface license. By purchasing up to 3 one-step-up licenses, the number of connections can be increased up to 256.

The module type Generic UDP (unicast and multicast) allows to configure up to 6056 analog and 16384 digital signals.

Text signals are supported among the analog signals with data type STRING[32].
Interface configuration

UDP port list

Setup the destination "port" range. As shown in the example, the range is defined from 5010 to 5017. The ibaPDA driver will therefore monitor port 5010 to port 5017. One controller can send multiple messages to ibaPDA by using multiple ports. You may enter multiple ranges that must be separated by comma.

Allow ports through firewall

When installing ibaPDA, the default port numbers of the used protocols are automatically entered in the firewall. If you change the port number or enable the interface subsequently, you have to enable this port in the firewall with this button.

Network interfaces

Using this drop-down list, you can select which network adapters on your computer are used for this interface. The sockets will be opened for communication only on the selected network adapters. In case a network adapter has multiple IP addresses configured, a socket will be opened for all of these IP addresses. At least one network adapter should be selected to get the interface configuration validated. If you select None, an error message will be displayed when validating the I/O configuration. By default, the option All is selected.
Connection table

Address

This is the source IP address of a connected controller.

Port

The destination port number shows which port is used by the controller for sending data to ibaPDA.

The connections in the table are sorted by address and port. Double-click on a row to navigate to the corresponding address offset in the memory view.
