TCP Send
When the TCP Send Bit (CIO 000002) turns ON, the
000102
TCP Send Error Flag (CIO 000102) is turned OFF and
the TCP Sending Flag (CIO 000202) is turned ON to
initialize processing.
000202
When the TCP Sending Flag (CIO 000202) turns ON,
the status of the Port Enabled Flag (A20200) is checked
D02000
to be sure it is ON and a TCP SEND REQUEST com-
D03000
mand is sent using CMND(490).
D02000: First command word
D00020
D03000: First response word
D00020: First control data word
The TCP Sending Flag (CIO 000202) is also turned
000202
OFF.
If the Port Enabled Flag (A20200) turns ON and the
000102
Sending Flag (CIO 150902) turns OFF while the TCP
Sending Flag (CIO 000202) is OFF, checks are made
and if any of the following are true, the TCP Send Error
Flag (CIO 000102) is turned ON.
The Results Storage Error Flag (CIO 150914) is ON.
The contents of the Response Storage Area set in the
command code (D03010) is not 0000 Hex (normal end).
The Network Communications Error Flag (A21900) is
ON.
000002
After the execution results have been checked, the TCP
Send Bit (CIO 000002) is turned OFF.

When the TCP Receive Bit (CIO 000003) turns ON, the
000103 TCP Receive Error Flag (CIO 000103) is turned OFF
and the TCP Receiving Flag (CIO 000203) is turned ON
to initialize processing.
000203
When the TCP Receiving Flag (CIO 000203) turns ON,
the status of the Port Enabled Flag (A20200) is checked
D04000
to be sure it is ON and a TCP RECEIVE REQUEST
D04010 command is sent using CMND(490).
D04000: First command word
D00030
D04010: First response word
D00030: First control data word
The TCP Receiving Flag (CIO 000203) is also turned
OFF.
000203
If the Port Enabled Flag (A20200) turns ON and the Re-
000103
ceiving Flag (CIO 150901) turns OFF while the TCP Re-
ceiving Flag (CIO 000203) is OFF, checks are made and if
any of the following are true, the TCP Receive Error Flag
(CIO 000103) is turned ON.
The Results Storage Error Flag (CIO 150914) is ON.
The contents of the Response Storage Area set in the
command code (D04020) is not 0000 Hex (normal end).
