How does Mitsubishi plc communicate with Weinview touch screen?

To achieve communication between Mitsubishi Plc and Weinview touch screen communication is actually very simple, the steps are as follows:

1. Open the Weinview software;

2. Click “Edit” – system parameters;

3. Enter “Mitsubishi model” in the name of the dialog box that pops up;

4. Check the “PLC” below and select the PLC type.

5. Communication can be realized by connecting the communication line.

Where is the Weinview touch screen IP address?

If it is a touch screen in use, you want to modify the IP address, then
1, open in the edit menu,
2, system parameter settings.
3, in the pop-up interface,
4 Select the general properties submenu,
4 Then change the Quick Select window button settings to Enabled.

Re-download the program, after the download is complete, there will be an arrow in the lower right corner of the touch screen, click once, enter the password, the default is 111111, you can modify the IP address.

How to realize the manual automatic mode of the Siemens s7-200 plc

For example: I0.0 is the toggle button, when it is turned on, it is manual, when it is not connected, it is automatic.
When programming, LD I0.0 sends a value to a memory, such as VB100=1.
LDI I0.0 sends another value to that memory, such as VB100=2,
This will be distinguished, and then use the comparison command, when VB100=1, adjust the manual program, when VB100=2, adjust the automatic program.

Weinview Touch screen and Mitsubishi PLC connection How to set up

1. Click on the desktop and click on File to open the system settings.

2. Click on the device to select the PLC port and then select the Mitsubishi FX series.

3. Next, you can see many options on the interface. The download port selects the Mitsubishi FX series.

4. Expand the port to select the Mitsubishi FX series. Click OK.

5, all the settings to complete the point to download it.

Siemens PLC’s ATCH interrupt instruction is used

The Interrupt Connection Instruction (ATCH) associates an interrupt event (EVNT) with the interrupt program number (INT) and initiates an interrupt event. According to the specified event priority group, the PLC provides services for the interrupts in the order of first come first served.

Only one user interrupt can be activated at any time. When other interrupts are active, the CPU issues an interrupt and temporarily enqueues, waiting for later processing. If there are too many interrupts and the queue cannot process, set the queue overflow status bit. Reset these bits when the team is empty.

The interrupt routine must consist of three parts: the interrupt program label (ie the number of the interrupt event), the interrupt program instruction, and the unconditional return instruction. The DISI, ENI, HDEF, L SCR, and END instructions cannot be used in an interrupt program.

Weinview touch screen (TV, CV, D, CV2, SD, R, Z respectively correspond to Mitsubishi PLC)

TV: the current timing value of the timer;
CV: current counter of the 16-bit counter;
D: data register;
CV2: current counter of the 32-bit counter;
SD: the current value of the status register;
R: file register, which can be found in the PLC parameter, PLC file setting —- file register
Z: Index register

How to deal with Siemens PLC analog quantity

Analog input: use MOV command, input is AIW0 or AIW6 (see if your PLC has its own analog input), the output is VW0,

Analog output: use MOV instruction, output is VW2, output is AQW0 or AQW6 (see if your PLC has its own analog input),

Analog input and output, PLC comes with analog processing.

For example, if you input 4-20ma signal, the analog input channel is 0-20ma, then the input signal is output to VW0, corresponding to 6400-32000. The output is the same.
