Page 58: 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. -
Page 59: Protocol Overview
PROTOCOL OVERVIEW The client sends a command to the Smart-VS and receives a reply with the result. The Smart-VS (server) is able to process only one command at a time. There are two types of commands: 1. Device control commands 2. -
