TCP Connections The web server module uses one TCP connection for each IP address
to which the module is connected. Multiple CIP connections can go
through a single TCP connection. Examples of TCP connections are:
• HMI (human-machine interface) to a controller that supports
EtherNet/IP communications.
• Logix MSG instruction to a controller or workstation.
• OPC or DDE accessing a controller.
The web server module supports 64 TCP connections that handle
CIP connections.
