Anonymous users2024-02-121. Input module:
The input interface of the PLC is a photocoupler, which consists of two light-emitting diodes and a phototransistor.
Among them, the light-emitting diode adds a changing electrical signal to the input end of the photocoupler, and the light-emitting diode produces the same optical signal as the input signal. In the linear operating area of the optocoupler, there is a linear relationship between the output signal and the input signal.
When the switch is closed, the diode emits light, and then the triode turns on under the illumination of the light, inputting a signal into the internal circuitry. When the switch is disconnected, the diode does not emit light and the triode does not turn on. The input signal to the internal circuit converts the external switching signal into a digital signal that can be accepted by the PLC through the input interface circuit.
2. Output module:
Relay output interface circuit for PLC.
When the internal circuit outputs a digital signal 1, there is a current flowing through the relay coil, and then the normally open contact closes, providing the current and voltage that the load conducts. When the internal circuit outputs a digital signal 0, then no current flows, no current flows through the relay coil, and then the normally open contact is disconnected, disconnecting the current or voltage of the load. That is, the internal digital circuit is converted into a signal through the output interface circuit to make the load operate or not.
3. Communication module:
MelsecNet H and CC-Link use cyclic communication to send and receive messages automatically and periodically, without the need for a special data communication program, with simple parameter setting.
MelsecNet H and CC-Link use broadcast for circular communication to send and receive, so that data can be shared on the network. For the Ethernet, Melsecnet H, and CC-Link networks used in Q Series PLCs, it is easy to set network parameters and various functions on the GX Developer software screen.

What is the output of the Mitsubishi analog module?
Hello dear, happy to answer your <>
It is mainly used to convert digital signals into analog signal outputs. It can be connected to different types of equipment and dust shed systems for effective logistics control and production automation. Similar to digital modules, ANK analog modules also need to be properly connected to input or output devices in order to function properly.
Therefore, it is necessary to correctly connect the output of the Mitsubishi analog module, 1Prepare the required equipment and cables2Wiring the module correctly3
Configure the module block parameter 4Test the output signal.
Here are some <> related extensions that we hope you will find helpful
1.Prepare the required equipment and cablesFirst, you need to confirm the type of output equipment, such as motors, motion controllers, inverters, etc., and prepare the corresponding cables. In addition, it is necessary to confirm the output type (voltage or current) of the module to ensure that the cables are matched.
2.Wiring the module correctly, and then, connect the module with the corresponding input pins of the device. In general, the output pins of the module correspond to the input pins of the target device and are connected by a cable.
When connecting the cables, pay attention to the poles of the pins and connect them correctly. 3.After the configuration module parameters are connected, the relevant parameters need to be configured to correctly identify the signal type and output range of the tomb.
For example, the output range of voltage or current needs to be set to ensure that the output signal range matches the requirements of the device. 4.Test the output signalFinally, the output signal needs to be tested to ensure that the signal is set correctly and the output quality is good.
Usually, the signal output by the module can be detected by a special grinding instrument or equipment. In general, the correct connection of the output of the Mitsubishi analog module requires strict compliance with the precautions when connecting the cables, and the relevant parameter configuration and testing to ensure the quality and safety of the output. Only in this way can effective logistics control and production automation be achieved.

Anonymous users2024-02-10Now Mitsubishi's manuals and materials are flying all over the sky for free, although the reason is the same, but different series of models, wiring methods are different, such as Mitsubishi's FX series and Q series. It is advisable to take a look at the programming manual or user manual, which has ready-made wiring diagram examples.

Anonymous users2024-02-051 Every scanning process. The input signal is sampled centrally. Refresh the output signal centrally.
2 Enter the refresh process. When the input port is closed, the input has a new state during the execution phase of the program, and the new state cannot be read. The new state is read only when the program performs the next scan.
3 A scanning cycle is divided into input sampling, program execution, and output refresh.
4 The contents of the component image registers change as the program is executed.
5 The length of the scan cycle is determined by three strips. (1) The speed at which the CPU executes the instruction, (2) The time occupied by the instruction itself, and (3) the number of instructions.
6 Due to the use of centralized sampling. The way in which the output is centralized. There is a phenomenon of input and output lag, that is, the input and output response is delayed.

Anonymous users2024-02-04Obviously, this is a retreat control, and I usually use PID control for this control.
The program is not complicated, but you haven't even explained the specific situation, such as the specific model and configuration of the most basic PLC, how do people write programs? There are also specific control methods, such as what kind of treatment is not in the range of 9-10mm? So not to mention the control part, I can't even write the configuration part.
In fact, it is recommended that you write such a simple thing yourself, so that you can improve.
For this simple control, you first configure the PLC, the address is assigned first, the program part is not difficult, and there are many examples of AD and DA on the Internet. The most complicated control of your tomb is the PID control.
From my point of view, such a simple control can actually be done without using a PLC, using a smart meter such as UDC3000.
The input of the PLC is active except for the current and voltage signal input, but a signal module is required; The switch signal input is passive, no relay is used! Generally, the input does not need a relay, depending on the occasion in which it is used. If the output is within the allowable value, the load can not pass through the relay, but the circuit is generally carried by the relay, and the life of the PLC will be shortened if the relay is not used! >>>More
Mitsubishi PLC programming program how to write PLC Hello, 1, after the program is written, you need to transform the program first, there are three ways to transform: the first is to press the F4 key of the keyboard directly, the second is to click the "transform" menu bar, and then click the first item "transform", the third is to click the "program transform" button of the toolbar, we choose the appropriate transformation method according to their own habits 2, after the program is transformed, you need to check whether there are syntax errors in the program, This check only self-diagnoses the syntax, not the design content. To check the program, click "Program Check" in the menu bar of the tool. >>>More

These two are mainstream PLCs, one made in Japan, one made in Germany, I have used both, both are very representative, it is recommended to learn both, you can learn Mitsubishi's first, because most of the programming methods of other brands of PLC are imitation of Mitsubishi, especially domestic brands, just like the Delta I use now, and Xinjie, which is almost exactly the same as Mitsubishi. Mitsubishi is what a traditional ladder looks like. And Siemens is also unique, although he also said that it is a ladder diagram, but his is a modular ladder diagram, which looks more intuitive than Mitsubishi's, and the step7 software is also very easy to use. >>>More
