How to Capture the Simulation Screen Display
Screen capture is always required for users to edit manual guide. There are two ways of capturing the simulation screen display:
A. Capture screen on PC;
B. Use “Screen hard copy” function of EasyBuilder Pro:

A. Capture screen on PC
During on-line simulation or off-line simulation, press “AltPrint Screen” on keyboard to capture the simulation screen. Paste it into an image editing tool and save it.
B. Use “Screen hard copy” function of EasyBuilder Pro
1. Open EasyBuilder Pro project file. Create a function key and check the “Screen hard copy” radio box in the general setting window. Set the printer to “USB disk 1”.
Notice: It is suggested to create the function key object in the “Common Window”, since that the objects in this window can be applied to all other windows;
Click “Object / Button / Function Key”:
2. In the popup window, check the “Screen hard copy” radio box under the “General” tab. Set the printer to “USB disk 1”. Click “OK” to finish
3. Start off-line simulation. Click the print button that is created in the previous step to capture the simulation screen and save it as an image file under the path “\usb1\hardcopy”.
The image is saved in the following path C:\EasyBuilder Pro\usb1\hardcopy:

How to backup a project
An EasyBuilder Pro project contains the source project file (*.mtp), and a number of library files (*.flb, *.blb, *.plb, *.slb, *.snd, *.lbl, and *.glb). These can be individually copied to another location for archiving, or to select theCompress/Uncompress option from EasyBuilder Pro's Tools menu.

Step 1.
Click Compress/Uncompress from Tools menu.


Step 2.
The following dialog is displayed. Click “Browse” to select source project for archiving.

All of the files associated with the project are compressed into a file, with a name of the form *.cmp. The compressed CMP file can be properly archived when this step is successfully completed.

EasyBuilder Pro - Alignment
In EasyBuilder Pro, there are two different ways to align the text on the object, one is to click the icons on the toolbar and the other is to set on object setting dialog.
  • By clicking the icons on toolbar (Left Alignment | Center Alignment | Right Alignment), the text, no matter single-lined or multi-lined, will be seen as one single label and will align to the outline of the object.

  • By setting Label>>Align on object setting dialog, the multiple lines of the text will align in the way set. This is a line by line alignment.

  • The line by line alignment of the multi-lined text can be done using Label>>Attribute selection on object setting dialog.

  • If an object is set to [Left] for [Align], when clicking [Left Alignment] on toolbar, the multi-lined text will be aligned along the left edge of the object.

  • The way above is same for [Align Center] and [Align Right]. The multi-lined text will display according to the setting of Label>>Attribute>>Align.

    The illustration below shows when [Left Alignment] icon is clicked, the text content are still displayed in the way they are set in object setting.

  • If object text is set with multiple states, tick [Tracking], in this way when moving text in one state, the texts of other states will also be moved in the same way.

  • Move object text in state 0; check the other states to see if the texts in those states all move the same way as in state 0. If [Tracking] is not selected, only text in one state will be moved.

Notes on USB Cable

The following are some important points relevant to USB cable:


1. The PC must support USB 2.0 or USB 3.0.

2. Use a double shielding USB cable: Foil + Braid Shield.

3. The length of the cable should be limited to less than 1.8 meters.

4. If a desktop is used, the USB cable must be plugged into the back panel instead of the front. If a laptop is used, please remove the external power supply.

5. When downloading a project through USB cable, please remove all the other devices that are connected to HMI.

6. If download fails, the possible cause can be the incompatible USB driver on PC. Go to Computer Management » Device Manager to check if the correct USB driver is installed. If not, please go to the installation folder of EasyBuilder and find the usbdriver folder, to manually update the driver.

How to use the VNC server?

The VNC server is a standard feature on the HMI, allowing users to monitor HMI screen through a VNC client program.

Step 1. Enable the VNC server on the HMI. A single-connection allows only one VNC client connection at a time, while there is no such restriction for multi-connection.

Step 2.
The default VNC login password is 111111, which can be changed on the VNC server.

Step 3. Use a third-party VNC client program, enter the HMI's IP and Port (5900), then proceed by entering the login password to access the HMI screen.

How to do floating point calculations with integers?

To gain a result with decimal place when dividing integers, please convert the integer to float first.

Please see the following Macro. D8=5 is the integer value gained from PLC.


Line 10: Since D8 is an integer, D8/10 is performed as an integer operation and the result is 0. The result is then written to a float variable, float_D8, therefore float_D8 is 0.0.

Line 15: Since temp is a float, temp/10 is performed as a float operation and the result is 0.5.

How to Connect Multiple Devices via One Serial Port?

To connect multiple devices via a single serial port, certain station number can be specified when configuring the serial port in System Parameter Settings » Device List. This FAQ explains the syntax of the variables that can be used when setting the station number for the read/write address of an object.

When setting the read/write address of an object, use the syntax “SN#address”. As shown in the following figure, 2#1 indicates station number 2, address 3x1.

Or, use syntax “VARn#address”. The valid VARn range is from LW-10000 (VAR0) to LW-10015 (VAR15). As shown in the following figure, VAR5#2 indicates that the station number is determined by the value in LW-10005 (VAR5).

Why can’t I open cMT Viewer or the screen is blank after opening cMT Viewer?


When using an older computer to open cMT Viewer, sometimes the system may show error message or the screen may be blank. This document shows how to solve this issue.




The cMT Viewer application requires a 3D graphic API, OpenGL (Open Graphics Library) newer than version 2.1. If you use an older PC or laptop that runs the OS like Windows XP or Windows Vista, the driver of the graphic chips may be outdated, and doesn’t support newer version’s OpenGL. Please download the latest driver of the graphic chip from the supplier. 

How to change the HMI model in the project?

Adapting the project model to meet diverse customer needs is a common practice. By streamlining this process, significant reductions in both time and costs associated with unnecessary edits can be achieved. Below is an example demonstrating a smooth transition from MT8103iE (1024 x 600) to cMT3108XP (1280 x 800).

Step 1. Open EasyBuilder Pro with the file for MT8103iE.
Step 2. Go to [Home] » [System Parameters] » [Model] » [HMI model], then choose cMT3108XP (1280 x 800).

Step 3. After pressing OK, select window and object adjustments in the "Resize Windows/Objects" dialog box, which appears due to the varying resolutions of HMI models. Then, recompile and download the project to the new model.

Step 4. After pressing OK, if converting from the MT Series to the cMT/cMT X Series, an additional Project Migration Report will appear. This report informs about the automatic changes made by EasyBuilder Pro.

The files from the cMT/cMT X Series cannot be converted to MT Series files.

How to solve display problems on Weintek software?

If you encounter one of the following problems when using Weintek software on a PC or laptop, please see this solution.

The objects appear blurred in EasyBuilder Pro editing screen.
2. Content displayed incorrectly in cMT Viewer.
3. Content displayed incorrectly in EasyLauncher.
4. Content displayed incorrectly in EasyAccess 2.0.

Certain Weintek software requires a newer version of OpenGL (Open Graphics Library), which is an API for rendering 3D vector graphics. If you are using a PC or laptop with an older display driver, the new OpenGL may not be supported.
In this case, updating the display driver downloaded from its official website is recommended. If the problem is not solved after updating the driver, please find EasyBuilder Pro folder and run DisplaySetting.exe, and then select “Software render” radio box. The display should appear normal after restarting the Weintek software.
