Results Storage Area Response Codes
The area in which the results of the command execution are stored. The first
byte specifies the memory area and data type (variable type). The 2nd to 4th
bytes specify the beginning address of the results storage area. Refer to
page 160 for details about the variable types and addresses that can be spec-
ified.
The maximum number of bytes of data to be received is given in the com-
mand. The number of bytes of data received will be stored in the results stor-
age area. Up to 1,984 bytes can be specified.
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 will be
set as the results storage response code. The value is set in units of 0.1 s.
The timeout time will be unlimited if the value is set to 0.
The IP address of the node sending data is stored in hexadecimal.
The port number of the node sending data.
The data sent from the remote node.
If a packet is received which contains more bytes than the number specified in
Number of reception bytes specified in the command, the specified number of
bytes will be stored and the remainder of the bytes will be discarded.

option was enabled and a socket service was used with a
CMND(490) instruction.)
