Parameters
UDP Socket Number (Command): Specify the UDP socket number to be
opened as two bytes between 1 and 4.
Results Storage Area (Command): The words 0 to 255 and 256 to 511 of the
memory area, words 0 to 6143 of the data memory, and words 0 to 6143 (each
bank) of the expansion data memory can be used. However, do not designate
the special auxiliary area. Refer to 11-1-4 Memory Area Designations. When a
bank that does not have expansion data memory is designated, the Results
Storage Area Error Flag will turn ON.
Number of Reception Bytes (Command, Results Storage Area): The maxi-
mum number of bytes of data to be received is given in the command. The num-
ber of bytes of data received will be stored in the results storage area. Up to

Note If more than the specified number of bytes is received, only the specified amount
will be stored and the remainder will be discarded.
Timeout Value (Command): Specifies the maximum control time between
receiving the receive request and storing the result. If this set time limit is
exceeded, the code for a timeout error (0080) will be set as the results storage
response code. The value is set in units of 0.1 s. The timeout time will be unlim-
ited if the value is set to 0.

ing data.
