Before learning PLC,it is best to learn about relays.Don’t underestimate relays.If you can use relays as control circuits,you are not only learning PLC quickly but also have a deep understanding.Long story short,
1:Learning relays,delayers,counters
2:Recognize various sensors,switches,solenoid valves,motors and their related.
3:Buy a PLC learning machine
4:Upload the program,debug the program,and write the program yourself.
5:Remove the PLC learning machine,assemble it by yourself,and add your own creativity.
6:The above 5 points are done,you have surpassed the PLC beginner,you should be able to do some small cases by yourself.
学PLC之前呢最好先学习一下继电器,大家不要小看继电器,能用继电器做控制电路的话你在学PLC不仅快而且理解深刻。长话短说,
1:学习继电器,延时器,计数器
2:认识各种传感器,开关,电磁阀,马达及其相关。
3:买一台PLC学习机
4:上传程式,调试程式,自己动手写程式。
5:将PLC学习机拆掉,自己动手组装,并加上自己的创意。
6:以上5点搞定,你已经超越了PLC初学者了,应该可以自己搞一些小案子了。
