DMC leveraged our experience with industrial automation platforms to evaluate a legacy plastics bagging line and propose a controls retrofit to modernize the system. The legacy Telemecanique (now Schneider Electric) control software was evaluated and re-developed for a Siemens S7-1200 PLC. An HMI application was created to replace the obsolete terminal, improving operator efficiency and providing diagnostic information that was not available in the original machine configuration.
DMC worked with partner firms to quickly replace and rewire the controls hardware to minimize machine downtime, as well as provide engineering documentation of the revised system. The retrofitted machine has proven to be much easier for operators to use and for maintenance departments to service, and has dramatically improved the reliability of the system.
