Here’s a quick overview of how to connect it to each of the popular industrial networks.Ī widely used method to integrate multiple vendors’ automation controllers is OPC (OLE for process control). That is just one example of how LabVIEW can be used with communication schemes. In the end, they maintained their existing PLC control scheme but augmented it to build a better product. The thickness measurement that the PLCs now use is more accurate than before and the customer can produce better quality and more consistent steel. Then they output a simple analog voltage in the 0-10 V range that corresponded to the thickness of the steel over a cable connected to the existing PLCs controlling the rolling mill. LabVIEW will provide simple updates to a PLC system such as pass/fail status.įor example, a customer used CompactRIO and LabVIEW to acquire a high-speed voltage reading from a gamma-based thickness sensor, and perform the complex inline signal processing required on that data to calculate an extremely accurate thickness measurement for the steel they were rolling. The simplest way to integrate LabVIEW into an existing system is to use the basic analog and digital I/O capabilities of PACs and PLCs to exchange signals. Because LabVIEW can interface to most industrial networks, PACs are commonly used to augment the PLCs in an existing machine or automation process to increase efficiency or predict maintenance of mechanical gearboxes and motors. PACs outperform PLCs in the areas of high-speed analog measurements and intensive processing algorithms needed for applications like machine condition monitoring (MCM) or machine vision.

When coupled with PACs, this platform offers a superset of traditional PLC functions, making it easy to retrofit or upgrade an existing installation. LabVIEW is a visual programming platform and development environment that can be used to support the connection of laptops and Programmable Automation Controllers (PACs), including CompactRIO, PXI/cPCI systems, and Industrial PCs (IPCs) to a variety of industrial networks and web technologies.Ī CompactRIO programmable automation controller connected with the NI 9144 modular EtherCAT slave chassis over standard CAT5 cabling.
