Real case and customer evaluation

A paper-making enterprise had a main control failure of the PLC-5 production line. The original model 1785 L40C was in extremely limited supply in the market, and the production line was at risk of shutdown. We provided fully inspected and disassembled good products. After delivery, we cooperated with the customer engineer to complete program loading, ControlNet networking debugging, and the equipment was successfully restored to production, avoiding long-term production losses.

"Old equipment is difficult to find reliable 1785 L40C. After receiving the goods, the communication was normal, and the test report was complete. This solved the spare parts problem for the production line." - Equipment engineer in the paper-making industry.
