PLC高速輸出100kHZ、200kHZ，有什麼差別?影響?

PLC規格裡，一定會寫到 高速輸出接口，速度100kHZ、200kHZ，
有什麼差別??

100kHZ = 每秒100K個脈波=每秒100000個脈波。

例：
每個脈波走1um，那每秒走100000個脈波，
不是就100000um=100mm，每秒100mm。

100mm x60=6000mm分鐘=6米/分鐘。

就可以推算出最高速度。

當我的最高速度要超過6米/分鐘時，怎麼辦???
1.更換PLC........................
2.將脈波分辦率降低，從1脈波1um，變成1脈波2um，就可以把最高速變快2倍。

The error generated by the PLC scan

The error generated by the PLC scan
To decide everything in the digital era, all of the CPU clock.
Still have to go through the CPU computing, and then output the results.


A relatively simple

- | X0 | ------- (Y0) -
X0 trigger Y0 output.
General requirements, we know that it is immediately output.
If high-speed machines, in fact, has been delayed for a scan time of about (10 ~ 20ms).

The output contacts are usually the end of the scan will be output.



For example:
Machine speed of 80 m / min, 10ms difference of about 13mm.

General photoelectric sensors, sensor response time, about ns level.
