Not bad, not bad. Well done, high salary. There are about 5000 people engaged in automatic programming (with certain programming skills) in China. PLC programming is also an industry that eats young people's bread. The update speed is a bit fast. You should constantly familiarize yourself with new programming tools. Take Siemens as an example. It now has S7-200, S7- 1200, S7-300 and S7. S7-200 needs to be familiar with V4.0 STEP 7 MicroWIN SP9 (which will be eliminated soon), S7- 1200 now uses Broadcom (which will be integrated in the future), s7-300 and s7-400 use step 7 5.5(400 generally uses PCS7), etc. Special modules also have their own procedures, and weighing modules need to be familiar with Siwatool MS and US for calibration. The wireless module SCALANCE needs to be familiar with the main setup tools. If you control servo, you need to be familiar with STATER, WINCC, touch screen, etc. This requires a lot of time accumulation and on-site debugging experience, and work generally requires travel, so you have to learn PLC, unless you can do research and development in a big company, it is a brain-consuming industry.
