Industrial machinery electrical equipment control and drive
Real - time serial communication between devices
1 Scope
This standard specifies the bus interface between the real-time serial communication data link (bus) between the industrial equipment electrical equipment control and the drive unit
And communication protocol specifications, the purpose is to achieve real-time serial communication protocol based on industrial machinery electrical equipment between the control device, sensors,
I/O and other devices to support the transmission and response to support interoperability between devices.
This standard applies to metal processing machinery, textile machinery, printing machinery, sewing machinery, plastics and rubber machinery, woodworking machinery and other electrical facilities
Standby open CNC system. Other industrial machinery and equipment with the open CNC system can also refer to the implementation.
