Communicate
This palette groups several steps whose purpose is to facilitate communication between your inspection application and external devices.
| Step Name | Description |
|---|---|
| Read/Write I/O | Reads and writes digital I/O lines on NI Smart Cameras and NI image acquisition devices. |
| Read/Write I/O (NI-IMAQ I/O) | Reads and writes digital I/O lines and ports on NI CVS-1450 Series Compact Vision System or NI PCI-8254R/PCIe-8255R IEEE 1394 interface devices with reconfigurable I/O. |
| Read/Write I/O (NI-DAQmx I/O) | Read and writes digital and analog I/O lines or ports on NI data acquisition (DAQ) devices. |
| Generate Pulse | Generates a single pulse or a pulse train using the digital output lines on NI Smart Cameras and NI image acquisition devices. |
| Generate Pulse (NI-IMAQ I/O) | Generates a single pulse or a pulse train using the digital output lines on NI CVS-1450 Series Compact Vision Systems, or NI PCI-8254R/PCIe-8255R IEEE 1394 interface devices with reconfigurable I/O. |
| Serial I/O | Communicates with devices, such as a PLC or robot, through serial commands. You can export measurements and pass/fail results to external devices. You can also configure your system to wait for a signal from an external device to start your inspection. |
| TCP I/O | Communicates with devices through TCP commands. You can export measurements and pass/fail results to external devices. |
| Modbus Slave | Communicates with Modbus Master devices, such as touch screens and other Human Machine Interfaces (HMI) and terminals. Modbus is an application layer messaging protocol that provides client/server communication between devices connected on different types of buses or networks. Vision Builder AI supports both the serial and TCP/IP physical layers. Refer to Modbus Concepts for related information. |
