Summary
For automatic laser marking, NCSK designed customized laser marking machine which can connect with PLC。Custom 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 machine。Including:
1)Start Marking Signal:Machine start making when it’s active.
2)Stop Marking Signal:Machine stop marking when it’s active, and show warning information.
3)Safety Door Signal:Machine stop marking when it’s active.
4)File Select Signal:Use input signal to select the right file to marking。For example,INPUT[6:4] ”001” select file A to marking,INPUT[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 Marking:Active when machine is marking
2)Finished Marking:Output an pulse signal when finished marking.
3)Red light indication signal:Active 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.
