Modbus is a short distance with a very high value for money, a low-cost communication solution, but it also has shortcomings, such as low real-time quality, limited amount of data transmitted, low speed of communication, and vulnerability to interference, but it is not a flaw, and we cannot hide the disease because of its shortcomings. On the contrary, we have to constantly discover and address its loopholes and improve the reliability of our equipment. Today, i share with you a few experiences in the application of modbus. First of all, your modbus cable must not be in a trough, and some people tend to use beauty as a way of putting communication lines in an on-line trough, which is a very wrong idea, which is the way the lighting electricians think。
