8.2 Status (error status)
The status indicates the status during SEND/RECV instruction execution or after execution completes. If a SEND/RECV instruction does not complete normally, refer to the detailed information (Ethernet Port error response) and the status and review the instruction word format at the T2N and Ethernet Port states (operating modes).
The detailed information is stored in the register following the completion status when the completion status TermSTS value indicates a transmission error (0BH).
Figure 8.1 shows the structure of the status information. Tables 8.4 and 8.5 list the TermSTS values, and table 8.6 lists the contents of the detailed information.
The status (error status) has the following structure.

Meaning
•Occurs if a register other than XW, YW, W, LW, RW, D, F, T, C, or SW is specified as the data storage register in one of the following requests. Requests: RAS information readout, remote port loopback, UDP send/receive,
TCP send/receive, register read/write.
•In a register read or write request, the request specified a read or write from a T register to a register other than a T register.
(This also applies to C registers.)
•Occurs if a response is not received within the specified time for a remote port loopback or register read/write request.
