  • PLC control laser marking machine
    1. Summary

    For automatic laser marking, NCSK designed customized laser marking machine which can connect with PLCCustom function including

    1)Ethernet interface for remote data transmission

    2)Extended I/O for PLC communication

    3)Software Development Kit(SDK


    Figure 1-1 Automatic laser marking solution

    2. Extend I/O for PLC communication

    PLC need control signal and state signal to control the laser marking machine. So we add these signals in an extended I/O. The extended I/O can be DB15 or DB25, depending on how many signals need to be used.


    Figure 2-1 Laser Marking Machine Extended I/O for PLC control

    2.1 General Input Signal

    General Input Signals are use for controlling the working state of laser machineIncluding

    1)Start Marking SignalMachine start making when it’s active.

    2)Stop Marking SignalMachine stop marking when its active, and show warning information.

    3)Safety Door SignalMachine stop marking when its active.

    4)File Select SignalUse input signal to select the right file to markingFor exampleINPUT[6:4] ”001” select file A to markingINPUT[6:4] “010” select file B to marking

    Extended I/O support 8 general input signals,figure 2-2 shows the pin diagram:


    Figure 2-2 Pin diagram of input signal

    2.2 General Output Signal

    General output signals show the working state of laser marking machine

    1)Busy MarkingActive when machine is marking

    2)Finished MarkingOutput an pulse signal when finished marking.

    3)Red light indication signalActive when Red light is indicating 

    The output signal is TTL output by default. Short circuit or grounding should be avoided.

    3. Software Development Kit (SDK)

    NCSK also supply SDK for secondary development of software. With this SDK, you can integrate the core functions of laser marking software into your own program.

    The SDK is suitable for Windows system environment and the development language is C++. Figure 3-1shows a demo program developed by this SDK.
