ReadDevice
Imports data into an In-Sight vision system from another host on the network using a TCP/IP or UDP connection. For more information, see TCPDevice and UDPDevice.
Note:
- To establish a TCP/IP device connection between two In-Sight vision systems, both devices must be Online.
- When ReadDevice is configured to communicate via UDP, there is no buffering; if another data packet arrives before the last one was processed, the new packet will replace the older packet.
