Soft plc structure for press machine and punch press

The soft plc structure comprises a display screen (1), an IPC controller (2), a power supply (3), an EtherCAT coupler (4), a plurality of I/O modules (5), a plurality of servo slave stations (6) and a press machine (7), the display screen (1) and the EtherCAT coupler (4) are respectively connected with the IPC controller (2), the EtherCAT coupler (4) and the I/O modules (5) are respectively connected in series through a real-time Ethernet, the servo slave stations (6) and the I/O modules (5) are connected in parallel through the real-time Ethernet, and the press machine (7) is connected with the power supply (3). And the servo slave station (6) is connected with a press machine (7). A display and control integrated electric control platform is realized in the punching machine industry, a punching machine at the bottom layer can be controlled in real time, key data of operation of the machine can be displayed in real time, and a display and control integrated soft plc controller based on a real-time system can
