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
1,982 bytes can be specified.
Reception of 0 bytes indicates that the communications were forcibly cut by the
remote node. Close the socket.
Note If more than the specified number of bytes is received, only the specified amount
will be stored and the remainder will be read when the next data set is received.
Timeout Value (Command): 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 is unlimited if the value is set to 0.
Received Data (Results Storage Area): Stores the received data.
