The following programming example illustrates transferring 100 bytes of databetween an Ethernet Unit
and a host computer using TCP/IP communications.
z
System Configuration
The programming example uses the following system configuration. For the TCP connection, the
Ethernet Unit uses a passive open and the host computer uses an active open.
z
Data Flow
The data will flow between the CPU Unit, Ethernet Unit, and host computer as shown in the following
diagram.
Note
Here, “execution bits” refer to W0.00 to W0.0
