First of all, we need to know what we should learn when using P1C. First of all, we should understand the hardware composition of PLC, such as its input and output terminals, power terminals, grounding terminals, download ports, program running switches, and the significance of PLC indicator lights. Need to know some PLC and industrial Ethernet interfaces.
The second step is to learn to operate the programming software of PLC skillfully, and learn to use the software to build projects, write programs, debug programs and download programs. Now most PLCs have software imitation function. You can learn how to imitate software.
The third step is to be familiar with the structure of system instructions and programs. For example, FX series PLC has 27 basic instructions and hundreds of functional instructions. We should learn the basic instructions first, and then conquer the functional instructions one by one, so as to understand and write user programs.
The fourth step is to have tools to learn PLC. At present, the hardware of PLC is expensive, so we can learn with the imitation function of software. These powerful softwares support most instructions of PLC.
