3BDH000364R0002 PM783FB0 Considering that the inverter of the squeegee printing unit of the flat screen printing machine we developed is specialised, we did not use the common application layer protocol, but tailored our special application layer protocol. The physical layer protocol is responsible for the transmission of physical signals, decoding, bit timing, bit synchronisation, etc.; the data link layer protocol is responsible for bus arbitration, message framing, data confirmation, error detection, flow control, etc.; the application layer protocol is mainly responsible for the allocation of identifiers, followed by network start-up or monitoring node handling, etc.

3BDH000364R0002 PM783FB0 is a human-computer interactive control system, purely with sequential control or logic control can not meet the control requirements, therefore, the lift control system is controlled by random logic. At present, the control of the lift is generally used in two ways, one is to use the microcomputer as the signal control unit, complete the collection of lift signals, operating status and function setting, to achieve automatic scheduling of the lift and set selection of the operating function, the drag control is completed by the frequency converter; the second control method to replace the microcomputer with a programmable controller (PLC) to achieve the signal set selection of the control.
