TCP/IP COMMUNICATION
CONNECTION
The TCP/IP communication requires that a connection be initiated between the two
devices. The Smart-VS (server) is listening on port 1023 and the PLC or PC (clients), must
send a connection request to establish communication. When the communication is
established, commands can be sent to the device.
