Causes and Fixes

Be careful, with UDP there is no guarantee on the datagram validity , if the datagram in not complete the inverter will trip in ILF, and it's necessary to have some time to analyse 1525 bytes and a clogging is possible at the input card, try to increase the polling and if it's possible use the TCP mode.

USER MANUEL P100 English version : The Ethernet card is compliant with ETHERNET 2 frames format (IEEE 802.3 is not supported).

If you server can support only this mode, the only solution is to replace it.
