Possible problems with the Weiluntong touch screen

Software usage class problem

1. System parameters

1.1 How to delete the touch screen taskbar work button?

Set "Edit/Set System Parameters / General / Work Button / Properties" to "Off".

1.2 What is the meaning of RS485 DEFAULT/RS485 2W/RS485 4W in the communication port type?

RS485 2W indicates that the wiring method is two-wire system, that is, two signal lines are connected except GND.

RS485 4W indicates that the wiring method is four-wire system, that is, the RS422 mode. Four signal lines are connected except GND.

RS485 DEFAULT indicates the above RS485 2W/ RS485 4W mode

However, we generally recommend to select 2W and 4W separately by wiring. It is not recommended to use RS485 DEFAULT.

1.3 How to encrypt the touch screen program to avoid other users uploading the program arbitrarily?

There is a password box on the "Edit / Set System Parameters / General" page. When 0 is written here, there is no password protected upload. If the customer fills in the password you need here (digital only does not support characters), download to After the screen is inside, the password input box will pop up when the user uploads again, and the password can be uploaded after the password is correct.

1.4 How to use the screen saver of the touch screen?

On the “Edit/Set System Parameters/General” page, there is a “Backlight Energy Saving” item. When 0 is selected, the screen will always be on after the touch screen is powered on. When other values ​​are selected, the screen will be off after X minutes. When the screen is touched by hand again, the light will light up again, which can extend the display life of the LCD screen.

1.5 How to turn off the buzzer sound of the touch screen?

On the "Edit / Set System Parameters / General" page there is a "Cursor Color" option, select "Off" to prevent the touch screen from making a sound.

2. Time

2.1 Why is the year display on the touch screen 606 instead of 2006?

This is because the position of the high and low bytes of the words in some PLCs is different from the general PLC. For example, Siemens PLC is the same, so in this case, you only need to manually re-enter the 2006 year on the screen.

2.2 How to modify the system time on the touch screen?

Use the value setting component on the touch screen to make time: address RW60000 is second, RW60001 is minute, RW60002 is time, RW60003 is day, RW60004 is month, RW60005 is year, RW60006 is week, must be set to BCD code (address Refer to Chapter 12, 12.3) of the manual, then download it to the screen and manually modify the time on the screen.

2.3 Why can't the system time be modified when offline simulation?

Because the time displayed on the screen during offline simulation is synchronized with the computer, the time to modify the screen system must be downloaded to the screen and manually modified.

2.4 Why is the trigger time in the event display all 0?

It is because "Internal RTC" is not selected in "Edit/Set System Parameters/General/RTC Source", and it can be displayed normally by selecting it.

3. Display

3.1 What should I do if the touch screen displays garbled characters?

In the EB500 software "Options / Language Selection" select "Oriental Language", save it and then compile it will not appear garbled.

3.2 Why is the following window not displayed when editing the EB500 software, a blank?

The window inside the software is too much open, causing problems to appear, closing some windows just fine.

3.3 How to open the CD and the files in the CMP format on the website?

The file with the suffix CMP is a compressed file format of the EB500 software, which must be decompressed with the decompression function in EB500. Select "File / Close", you can close all the windows in the software, make the whole screen gray, then select "Tools / Compression / Decompression", click the "Browse" button in the source file column of the "Unzip" item, click Unzip, progress shows that success is complete. The decompressed file is a file with the suffix epj that can be opened directly with EB500.

3.4 How to open a file with the suffix EOB from the touch screen to the computer?

The EOB file can be opened after being compiled by EB500 and decompiled. The windows in the software are closed, the whole screen is grayed out, then the tool is selected/decompiled, the file is finally browsed, the decompilation is clicked, and the progress display success is completed. It is.

3.5 Double-click the completed project file icon, what should I do if the bitmap is lost?

The edited picture program cannot be opened directly like this. It needs to be opened by the path from the EB500 software.

4. Use error

4.1 Newly bought touch screen After downloading the programmed program, what should I do if I can't touch or touch the crash?

First, turn the No. 2 DIP switch on the back of the screen to the ON position, and then power on to see the copyright of the last line of the screen. Under normal circumstances, it should be displayed as 2004. If 22002 or 2002 is displayed, it indicates that the software is downloaded or downloaded. Lower, please re-download with EB500 2.6.1 software.

4.2 Why did the new touch screen download program appear after the blue screen, white screen, black screen and other anomalies?

This phenomenon is generally the use of wrong download software, you need to re -download with the EB500 2.6.1 version of the software provided by our company can be repaired.

4.3 Why check the previous event record? Can only be turned up, not down?

This is caused by software setting error. Use the multi-state setting component to increase and decrease the scrolling up and down. It should be noted that when setting the decrement, it is easy to mistake the lower limit value as the upper limit. The correct setting should be 0.

4.4 Why doesn't the moving graphics do move?

This is because the control address is incorrect. There is a register address in the properties of the mobile graphics itself, but it cannot be used when controlling the movement of it.

The address it moves is to add 1 to the address of the graphic itself. For example, if the setting of the moving graphic attribute is D0, then the value in D1 is the size of the range that controls the movement of the graphic.

4.5 Touch screen communicates with Emerson EC20 PLC. When it is double word, why is the reading value of the screen different from the value of PLC?

This is due to the unique addressing method of the Emerson EC20 PLC. Therefore, in the EB500 software, when the PLC is a double word, the device type of the component read address should be D-DOUBLE/C-DOUBLE, and it is not possible to adjust the number of words to 2 on the basis of the single word as other PLCs.

5. Other

5.1 Why do I get the prompt "EasyWindow must running from EasyManager or EasyBuider" when using the offline simulation function?

If the serial port is selected as COM4 or above (does not include COM4), this prompt will appear, but it will not affect the download function. It can be downloaded with COM5-COM10. It is recommended to use COM0-COM4 serial port when downloading.

5.2 Does the bar graph and trend graph components in EB500 software support floating point numbers?

Currently not supported, only decimal integers can be read.

5.3 How to switch windows with PLC internal address?

It is sufficient to switch the basic window element with the PLC control element.

5.4 Can the MT506S program be downloaded to the 510L ?

This type of download cannot be supported because the software size is smaller than the large screen size. Small size projects cannot be downloaded to large screens.

5.5 When using a data transfer component to transfer multiple bits of a word address, why are some bits not transmitted?

This is related to the bit transfer method used by the EB500. When transferring bits, the target LB address of the transfer must correspond to the bit address of the PLC. For example, W10.0~10.F, the corresponding LB must be an integer multiple of 16 addresses, that is, it should be LB96~111, or 0~15, 16~32, and so on. When not aligned by a multiple of 16 bits, the remainder is the number that cannot be transmitted. For example, when it reaches 200, the remainder of 16 is 8, and 8 cannot be transmitted.

The most reliable way to use it is to convert it to a contiguous address and make the LB address consistent with it:

The consecutive bit address of W10.0 is: 10×16+0=160; it may be transmitted to LB160. If it is not convenient, it can also drive LB160±16x address (where x is an integer), as long as the remainder is the same.

5.6 Why does the download dialog box not pop up on the computer when downloading?

This situation often occurs after the reinstallation of the client computer system, because the customer did not delete the previous EB500 installation folder when reinstalling the system, and the file can be edited from the folder after the system is installed. At that time, the software is already in an abnormal state. The solution is to let the customer reinstall the EB500 once.

5.7 How to adjust the position of the label when the button component 1 is in the state?

The EB500 software screen toolbar has a status switch box that switches to a different state to adjust the position of the label in different states.

5.8 What do you want to do with the previous picture in the new project?

The user needs to refer to the previous picture when making a new project, but often the direct COPY will cause the picture to be lost, then summarize the following steps, please press this operation:

Open the old project and open the gallery to see which libraries have been added (bitmaps, vector diagrams to see), and record them;

Close the old project, create a new project, add the newly recorded library to the gallery, confirm the addition, save and close the new project; open the old project to copy the components of a picture, and then COPY to the new project .

Second, communication problems

1. Communicate with PLC

1.1 What should I do if I encounter PLC and touch screen communication?

The most common problem encountered by customers during the use of the touch screen is the problem of screen and PLC communication. When encountering communication failure, use the following steps to judge:

a. "Direct online simulation", ("Direct online simulation" method see 2.2 in this section) If the direct online simulation is not available, it means that the customer setting parameters are wrong, it is recommended that he use the settings on the manual to do, and the PLC inside The parameters should be consistent with the setting parameters of the screen.

b. If the direct “online simulation” is passed, then let him check if the communication line is correct (if it is the line made by the user himself, please check whether the male and female pins are arranged correctly, whether it is soldered or not, etc.).

c. If the wiring is checked, there is no problem with the wiring (the wiring must be judged according to the line number on the manual), then the program can be downloaded and the communication is normal.

d. If all of the above are normal, but still can not communicate, then the customer must send the screen back to the company for testing.

1.2 Can a touch screen communicate with two Mitsubishi FX PLCs?

It is completely possible to use Mitsubishi's 485BD module and Computer link protocol for communication. The specific method is described in the multi-screen chapter of the manual.

1.3 How to determine the station number when Delta and touch screen communication?

Please determine according to the station number of Delta itself, because there are two cases of Delta PLC station number, one can only use 0 as the station number, and one can only use 1 as the station number. More questions can be searched for just the power, there will be a technician to answer for you.
