It is possible to transfer the same data to all nodes in a network simultaneously
by designating the destination node as 00. This transmission is called broad-
casting. No responses are returned to broadcasts. (Broadcasting cannot be per-
formed with the RECV(98) instruction.)
the bridge function and gateway function cannot be used.
The NETWORK READ/WRITE instructions (SEND(90)/RECV(98)) enable
data to be sent and received between nodes within a single network under
control of a user program. The user can specify that a receiving node send a
response to the sending node to acknowledge receipt of the data. The basic
specifications of these instructions are given in the following table.
The data transfer area, which is used for data transmission and reception using
the SEND and RECV instructions, varies with the PC.
