Controlink Systems LLC has been developing software solutions for manufacturing environments since 1998. From its headquarters in Lawrenceburg, Indiana, the company has built a reputation for linking systems together across CNC machining, process monitoring, end-of-line testing, and industrial control. As a member of the NI Partner Network since 2000, Controlink combines long-standing technical expertise with a practical understanding of how real shops operate every day. Their work focuses on creating understandable, user-friendly interfaces and dependable automation tools that run continuously in demanding production settings. The goal is simple: help manufacturers improve productivity, reduce downtime, and solve complex integration challenges with software and engineering that make sense on the shop floor.
A shopfloor system is the combination of software, machine communications, and workflow tools used to manage production activity where parts are actually made. It can include CNC file transfer, remote program requests, machine monitoring, process data collection, and links between engineering and operators. The goal is to improve control, reduce delays, and keep production moving with accurate, current information.
