Application of CANopen and Modbus Protocol in rotary screen printing machine control system

The application of CANopen and Modbus Protocol in rotary screen printing machine control system was introduced, making ZIMMER rotary screen printing machine as the research object, by Delta touch screen, SYSTEC CANopen series PLCmodule-C14, MOOG servo controller T161, MOOG servo motor G400 and OpenPCS programming platform. And it was shown that how to implement the communication between touch screen and non-standard controls PLCmodule-C14. CANopen protocol is a standard protocol based on the application layer of CAN bus popular in Europe, its application of rotary screen printing machine at China is still a blank. It illustrates a good prospect of application and extension.
