‌The application of I/O remote modules in packaging machinery is mainly reflected in signal acquisition and control, which improves the flexibility and efficiency of the system. ‌

Application scenarios and functions

In packaging machinery, I/O remote modules are mainly used for signal acquisition and control. For example, in a fully automatic packaging machine, the I/O remote module is responsible for collecting sensor signals and controlling various execution devices to implement control processes such as bag making and coding. In addition, the I/O remote module is also used in the heat sealing bag process of the packaging machine to achieve precise temperature control through EtherCAT communication and record various alarm information.

Specific application cases

In automated packaging systems, I/O remote modules are widely used in equipment such as automatic carton unpacking machines, automatic carton sealing machines, and automatic strapping machines. These devices use the PLC + remote I/O solution for signal collection and control, realizing the automation of the entire packaging process from unpacking, packing to palletizing. The remote I/O module is connected to the main PLC through a communication line, and collects signals in a distributed manner, simplifying wiring, improving processing speed, and saving the number of I/O points of the PLC.

Communication methods and advantages

I/O remote modules have various communication methods, including free port communication, PROFIBUS, MODBUS, PROFINET, etc. These communication methods enable I/O remote modules to adapt to different industrial environments and needs. By using I/O remote modules, distributed signal collection and control can be achieved, greatly improving the flexibility and efficiency of the system while reducing wiring and maintenance costs.
