-Learn wiring first (various modules, especially analog input and output)

Second, hardware configuration (the software comes with various CPUs and IO)

Third, learn to simulate (communication can not be simulated, temporarily unnecessary)

Fourth, simple programming (running lights and the like, familiar with various timers, counters and other modules)

Fifth, deep programming.

1, establish FC, FB, DB, etc. , and learn structured programming.

Analog input and output (non-analog)

PID (non-analog)

Hardware settings such as high-speed pulse output and high-speed counting.

MPI, PROFIBUS, Ethernet and other communication protocols (cannot be simulated).

It's all my own experience and study. I can make a living by learning these five points ~

Hope to adopt decisively.
