TermSTS Status Meaning
03H Parameter error
• Occurs if a value other than 3 is specified for the module ID.
• Occurs if a value other than 1 is specified for the channel number.
• Occurs if a command number other than one of the following is specified for a
000FH, 0011H - 0014H, 0018H, 0021H, 0031H, 0032H, 0034H, 0035H,
• Occurs if a command number other than one of the following is specified for a
0015H, 0021H, 0033H, 0038H
• Occurs if a value other than 1 to 8 is specified for the socket identifier.
(See section 6.4 "Using the Ethernet Port Socket Interface".)
• Occurs if an incorrect parameter is specified in a RAS information readout
(See section 7.6 "RAS Information Readout".)
04H Memory write protect
• Occurs if an attempt to write is made when the remote registers were write
• Occurs if an attempt to read is made when the local registers were write
protected.
05H (Reserved)
06H Module error
• Occurs if the Ethernet Port is down.
Initialization in progress
• Occurs if the Ethernet Port is initializing.
Transmission complete
timeout
• Occurs if a T2N internal timer times out.
Requests: UDP open, UDP send, UDP close, TCP send, TCP close
07H No send channel (CH)
• Occurs if the corresponding Ethernet Port is not installed.
08H Port address out of range
• Occurs if the local port IP address was specified for the remote destination IP
Requests: Remote port loopback, register read/write
09H Incorrect transmission word
count
• Occurs if either 0 words or 486 or more words were specified for either a
register read/write or a remote port loopback request.
• Occurs if either 0 words or 1001 or more words were specified for a UDP/TCP
send/receive request.
0AH Boundary error
• Occurs if the specified area (start address + register range) does not exist in
the T2N data storage registers.
Requests: RAS information readout, remote port loopback, UDP send/receive,
TCP send/receive, register read/write
0BH Transmission error • Occurs if the Ethernet Port returns an error response.
Detailed information (the Ethernet Port response status) is stored.
0CH No I/O response
• Occurs if the T2N cannot access the Ethernet Port.
0DH (Reserved)
0EH Send data capacity
exceeded
• Occurs if a request is discarded when a T2N internal resource insufficiency
occurs due to increasing amounts of transfer data.
• Occurs if a T2N retransmission times out.
0FH (Reserved)
When a transmission error (0BH) occurs, details of the Ethernet Port error response are stored in the
register following the status. (See table 8.6.)
