Status

Also known as
duplex mode, data transfer mode

This signature is an inverter event message saying that the duplex mode (data transfer mode) of the network interface has switched from Full to Half. On SMA inverters the change is logged as event number 10254 in the event list. The Half status can come from a defective plug or a defective cable. It can also appear when the network connector is pulled or plugged in. On an Ethernet connection, check that the network cable and connector are undamaged and that the connectors are plugged in correctly. Also check that the DHCP server (router) and any network switches show correct operation. A separate event, 10255, reports that network load has returned to normal after a busy period. It points to a network overload, not a duplex change.
