•If the transmission data size for a single operation is larger than the reception data size, the
section of the transmitted data that exceeds the specified reception size is discarded, resulting
in the following error response.
Status: Transmission error (TermSTS = 0BH)
Detailed information: Insufficient data size(00C1H)
If this error is occurred, a reception data storage register of the T2N enters the data following
below. The data of slash bar is not received to T2N and discarded.
The number of transferred bytes
from Ethernet Port to T2N
The reception data itself
•The Ethernet Port uses a priority ordering in processing sockets 1 through 8. Therefore,
systems constructed so that socket 1 is activated frequently may not be able to process socket 8,
resulting in the following error response:
Status: Send completion timeout (TermSTS = 06H)
When constructing a system, take the socket utilization conditions into account when allocating
sockets. Since the send/receive processing for each socket requires about 50 ms, applications
that issue send or receive requests to a given socket should leave an interval of at least 50 ms
times the number of sockets used between each request.
(Interval between requests to the same socket) ≥ (Number of sockets used × 50 ms)
Similarly, the above intervals averaging 50 ms should be left between transmissions from
remote ports to the local port.
(Interval between remote port transmissions) ≥ (Number of remote ports × 50 ms)
f. Broadcast reception
It is possible to broadcast to all ports on the network using UDP sockets.
Receive side: Specify the transmission source IP address to be "0.0.0.0".
Specify the UDP port number for the broadcast transmitting socket as the
transmission source UDP port number.
The size of
reception data
(Specify the T2N) The size of reception
data of Ethernet Port
