With the development of economy, transmission belt machine is used more and more widely, transmission belt machine relay control system due to equipment failure rate is high, low reliability, large volume, inconvenient maintenance and renovation of many defects, but is eliminated gradually. This article introduced a new type of transmission belt machine PLC control system, to select the type of PLC, I / O wiring terminal, program design and control principle o
