while the UDP Receiving Flag (CIO 000203) is OFF, the
contents of the response code (D30027) in the Socket
Service Parameter Area is checked, and if it is not 0000
Hex (normal end), the UDP Receive Error Flag (CIO
000103) is turned ON.
After the execution results have been checked, the UDP
Receive Bit (CIO 000003) is turned OFF.
After the parameter has been set, the Receive Request
Switch (CIO 151904) is turned ON and the UDP Receiv-
ing Flag (CIO 000203) is turned OFF.
When the UDP Receiving Flag (CIO 000203) turns ON,
the following parameters are written to the parameter area
for socket number 1.
D30018: 0001 Hex = UDP/TCP socket No. 1
D30023: 0064 Hex = No. of send/receive bytes is 100
D30024 and D30025:
8203 E800 Hex =
