Description

The Generic TCP interface can be used by every controller able to send TCP/IP messages. Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite. The Generic TCP messages are IP Unicast protocols sent from one or several controllers to the ibaPDA system using a defined port number.

Each TCP connection is precisely identified within ibaPDA by the destination "port number" and "source IP address." The telegram between ibaPDA and the target system must have a fixed structure. The maximum length of the TCP/IP message is limited to 4096 bytes. 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 Generic ibaPDA interface can also be used for output signals. The interface is also available in the outputs area of the I/O configuration.

For more information see Outputs.

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

TCP port list

Setting 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 using multiple ports.

<Allow ports through firewall>

When installing ibaPDA, the default port numbers of the protocols used are automatically entered in the firewall. If the port number is changed here or the interface has subsequently been activated, it is necessary to release this port in the firewall.

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

IP address source

This is the source IP address of a connected controller.

Destination port

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