Which industrial connectivity options are included on NI Embedded Vision Systems?
NI Embedded Vision Systems can communicate with PACs, PLCs, HMI displays, and other automation devices through Ethernet protocols such as TCP/IP and Modbus/TCP and through RS232 protocols such as serial and Modbus serial.
The vision systems also feature built-in digital I/O and MXI-Express to synchronize an inspection and send part failure notifications. The EVS-1464RT and EVS-1463RT include TTL and optoisolated digital I/O lines for turning LEDs on or off, driving mechanisms that sort parts, alerting operators when a part has failed, or using PWM to control a motor to sort the parts. More advanced users can also reconfigure the FPGA behind the I/O lines on the EVS-1464RT for more customized I/O, timing, and triggering.
Real-time NI Embedded Vision Systems are also EtherCAT master devices, offering a simple way to integrate single-point I/O, including motion drives and I/O expansion devices. In addition, MXI-Express connectivity on all NI Embedded Vision Systems provides deterministic integration for waveform data and supports a variety of I/O in high-channel-count systems.
Are there real-time video display and HMI capabilities? Can I view images and results and interact with my inspection using an HMI or monitor?
NI real-time vision systems feature built-in drivers to output video through a built-in DVI port, so you can view images and pass/fail results from the inspection with a monitor or HMI. You can programmatically change all of the user-definable image overlays to create custom user displays.
Also, a simple Web browser on any Windows CE, XP, or XP Embedded touch panel can act as an operator interface (HMI) for selecting inspections, updating parameters, or training a new part. In addition to being a Web server, the EVS-1464RT and EVS-1463RT can be configured when programmed with LabVIEW to host Web services for streaming data.
What can I do with the FPGA on NI Embedded Vision Systems?
The EVS-1464RT (only) has an FPGA directly connected to the digital I/O lines. If your application requires precise timing or custom I/O behavior, you can use the LabVIEW FPGA Module to reconfigure the digital I/O lines to achieve additional functionality such as custom triggers, timing, PWM outputs, encoder-based queued pulse generators, customer digital protocols, and high-speed counters. This functionality is available only in the LabVIEW environment.
