What is the communication between Mitsubishi PLC and PLC programming software? -Solutions - Huaqiang Electronic Network
For beginners of a Mitsubishi plc, the first step is to use PLC to communicate with PLC programming software. But when we cross the first threshold, we often take a lot of detours. Often we can't make PLC and PLC programming software communication for a long time, but I don't know what the problem is. In fact, PLC can not communicate with programming software is nothing more than the following problems:
1. Use a poor quality communication cable.
2. The correct morning drive is not installed.
3. The communication port is set incorrectly.
4. The communication port of the PLC is broken.
How to solve the problem when encountering such a problem? In fact, it is very simple, just do the following countermeasures.
1. We want to buy a high quality communication cable.
2. Generally, the communication cable you bought is equipped with the drive CD of the cable. Just select the driver suitable for your computer system and install it according to the wizard.
3. Before the communication, we first check the com port of our communication cable through the computer management, and then set the com port in the “Transfer Settings†of our programming software.

Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
