number in the area reserved for transmission fails.
91H • Error in the TCP or UDP protocol (such as a transmission phase
error)
• The TCP socket was used to make the transmit request to the
socket (with the NOACK bit of the socket status is ON) due to
remote-station down.
92H • Occurs if the setting of the remote station IP address in the
remote station information area fails.
• Occurs if the remote station IP address network address differs
from the local station IP address network address.

Error in the
receive request
from S3 (Number
of words)
C1H Occurs if the data size

(1 to 1000 words).

the transmission request data is accumulated is smaller than the
data size of the transmission request for the TCP socket
transmission.
Remote station
window size is too
small
