1.828d有板载快速IO,快速io可以由NC同步动作控制；

软件有SW 24x SW 26x SW 28x对应周期：

ipo周期? Milling 9 ms 6 ms 3 ms

PLC cycle time 9 ms 6 ms 6 ms

PLC有中断子程序INT_0，、线圈输出有“立即输出”--(I)

Shortest response time: Executed in the servo cycle;

INT_0 For extremely fast responses to events, which absolutely required 

this. In INT_0, the direct access commands, that either access an 

internal, I/O image updated in the servo cycle or only the 

hardware of the onboard I/O, can be practically used.
