There are three methods, you can do it in combination with the on-site situation and your financial strength. 1. Use PLC + upper unit too software. The external signal enters the PLC, and the configuration software reads the signal through the PLC. The disadvantage of this method is that the cost is relatively high, but the advantage is that such a system has the control ability because of the PLC, and the programming is simple and easy to maintain. 2. There are three ways to buy a thermometer and pressure. You can do it according to the on-site situation and your financial strength. 1. Use PLC + upper unit too software. The external signal enters the PLC, and the configuration software reads the signal through the PLC. The disadvantage of this method is that the cost is relatively high, but the advantage is that such a system has the control ability because of the PLC, and the programming is simple and easy to maintain. 2. When buying thermometers and pressure gauges, all instruments are required to have RS485 communication function, and the communication protocol is open. Then these signals enter the computer through 485 communication. The shortcomings of this method are obviously that these instruments have a communication interface, which increases the purchase cost, and this method requires the upper computer to have programming experience. The advantage of this method is that if the field instruments are widely distributed and the distance is long, the cable cost will be saved a lot. 3. Purchase IO boards and modules similar to Advantech, connect these external signals to the module, and insert the boards into the computer. Similarly, this method also requires a certain degree of programming ability. The above methods are the methods that I have contacted and applied specifically, and it is not ruled out that there are many better methods. You have to choose the specific method based on the on-site situation. Similarly, if you don’t tell me how many points there are on site and what form of analog each point is, I cannot give you the PLC configuration. If you just get the signal, then you can complete many of the most basic PLCs. Personally, I strongly recommend not to choose a Japanese PLC! !
