System requirements

The following system requirements are necessary for the use of the Generic TCP data interface:

ibaPDA v8.7.0 or higher
Base license for ibaPDA + License for ibaPDA-Interface-Generic-TCP
Network connection 10/100 Mbit/s

For further requirements for the used computer hardware and the supported operating systems, refer to the ibaPDA documentation.

Note

It is recommended carrying out the TCP/IP communication on a separate network segment to exclude a mutual influence by other network components.

System restrictions

Depending on the device configuration and controller types, network-specific settings may cause problems when handling TCP/IP acknowledgments. See Troubleshooting (all ibaPDA versions).

Note

Generic TCP vs. Generic UDP

In modern networks, data can be transferred quickly enough for many applications using the TCP/IP protocol. However, in case of highly cyclical data traffic, such as in measurement data acquisition, the TCP/IP protocol is sometimes unable to meet the requirements ideally due to its principle of operation (handshake, TCP/IP acknowledge).

Users should therefore consider whether the simpler UDP protocol is sufficient or even the better choice for the planned application. The use of the UDP protocol often also has a positive effect on the performance of the sender (e.g. PLC).

iba AG recommends using the protocols as follows:

TCP/IP (ibaPDA-Interface-Generic-TCP): for noncyclical or triggered data transmission or for cyclical data transmission on timebases higher than 1 s
UDP (ibaPDA-Interface-Generic-UDP): for cyclical data transmission on timebases significantly shorter than 1 s
