Page 56: Tcp/Ip Communication
APPENDIX B 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 57: Protocol Overview
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. -
Page 58: Use Of Asynchronous Features
TCP/IP COMMUNICATION Use of asynchronous features An asynchronous feature must be started with the appropriate command. It will not be possible to run multiple asynchronous features at the same time. During the execution of the asynchronous feature, the device can be queried about the status of the activity. Once the activity is terminated, it will be possible for the client to request the finaliza- tion of the task, if provided, the finalization command will also contain the reply. -
