TechTip: Weincloud Dashboard

In this TechTip we’ll be running through setting up a Dashboard with Weintek’s “Weincloud Dashboard“. The Dashboard is a simple condition monitoring interface supported on selected EasyAccess Enabled cMT X Series HMIs. Firstly, login to your Weintek Domain account via https://www.weincloud.net , and under “Dashboard”, click on “+ Create New Project” Next, enter your project details, and click “Create”. You can now enter the development dashboard. Exit the Dashboard editor and Click onto “Data Source” – this is where we’ll set up the data that we’ll be monitoring. Choose “History” if you want historical data to be saved. HMIs that Continue reading TechTip: Weincloud Dashboard

TechTip: Weintek cMT X Series PLC Web Browser Object

TechTip for Weintek cMT X Series Web Browser Object

In a factory setting, it may be desirable to limit the access of the cMT X Series web browser. We can do this by unchecking “Show navigation bar” and using the Control registers instead. Control Word Codes:1 – Go2 – Reload3 – Stop4 – Back5 – Forward6 – Clear Cache7 – Clear Cookies For the favourites buttons, we’re using a “Combo Button” with 2 Actions Action 1 – Write constant string with our URL Action 2 – set the control word to “1” for “Go” Repeat for shortcuts required. As usual, we have a demo project for you to try Continue reading TechTip: Weintek cMT X Series PLC Web Browser Object

TechTip: Using PDF Reader on Weintek cMT & cMT X Series HMI

The ability to display PDFs on an HMI is a really useful feature; having machine manuals, hardware manuals, brochures, or work instructions available on a machine can help minimise downtime by ensuring valuable documentation remains with the machine. In this TechTip, we’ll be taking a look at the PDF Reader object available on selected Weintek cMT and cMT X Series HMI. To ensure your HMI supports the PDF Reader object, please check that it is not greyed out on the object menu in EasyBuilder Pro. PDFs are stored on a USB stick or SD Card, for clarity in this example, Continue reading TechTip: Using PDF Reader on Weintek cMT & cMT X Series HMI

TechTip: Using GETBIT in a Macro on Weintek HMI

Occasionally, you may need to read a bit or bits from a PLC or controller register if they are not directly accessible via the driver being used – an example of this could be a PLC status word where each bit represents the status of various PLC conditions, for example, “Battery Status” or “CPU Error” etc. Or it may be that you want to replicate some PLC logic that is otherwise inaccessible. The GETBIT macro instruction is very useful in these circumstances, enabling you to retrieve an individual bit and use that in conjunction with further logic such as an Continue reading TechTip: Using GETBIT in a Macro on Weintek HMI

TechTip: How to program Weintek HMI via Ethernet

This guide will show you how to connect a Weintek HMI to a PC via ethernet; to do this, we’ll be making sure that both screen and PC/laptop network adaptor are on the same subnet as each other.  Note: The illustrations in this Guide are based on an iE Series HMI. Other Series HMIs may appear a little different. For HMIs with dual ethernet, the IP addresses of the ports MUST be on different subnets.  Weintek System Settings1. On the Weintek HMI, tap the black arrow bottom right  2. To check if there is an IP address already set on the HMI, tap the Information button to show the settings for the device. In this case, we Continue reading TechTip: How to program Weintek HMI via Ethernet

TechTip: Connecting a Control Techniques Drive to a Weintek HMI Using Modbus RTU

This TechTip is about connecting a Control Techniques drive to a Weintek HMI using Modbus RTU. For the purposes of this TechTip, we’re using a CT Comander C300 drive fitted with an AI-485 option module. Drive SetupEither using the drive onboard menu via the keypad, or Control Techniques Connect, software, verify the communications settings (Address, Baud Rate, Data bits, Stop Bits, Parity) as these will need to be matched in your HMI project. Addressing FormatModbus Addressing format for Control Techniques drives is: 40000 + (menu number x 100) + (parameter number) The Weintek HMI does not require the 40000, so Continue reading TechTip: Connecting a Control Techniques Drive to a Weintek HMI Using Modbus RTU

TechTip: Window Change on Auto-Logout Weintek HMI

This TechTip is about automatically changing the HMI window when logout, or Auto logout occurs. This could be useful if you want to ensure that if a user with elevated privileges leaves the HMI without logging out then the HMI will return to a normal operating or information window. Auto logout enabled is set in the System tab of System Parameters Setting in EasyBuilder Pro. To achieve window change on logout or Auto logout, we’ll use a macro to check the value of LW 9222 – this is the system register holding the value of operable security classes. If a Continue reading TechTip: Window Change on Auto-Logout Weintek HMI

TechTip: Calculating The Difference Between Two Values Using a Macro In a Weintek HMI

This TechTip is about using a macro for a simple calculation to determine the difference between 2 values. To calculate the difference between 2 values, first we use the “>=” operator to determine if value1 is greater than or equal to value2, if this is the case, our result is calculated value1 – value2. If value2 is greater than value1 then our result calculation is value2 – value1. The macro is shown below: As usual there’s a demo project available for you to try out using EasyBuilder Pro’s excellent simulator. Download the demo here.

TechTip: Using the Shape Library with Weintek HMI

A frequently asked question we receive is “How do I create a multi-state lamp – for example to use with a Word Lamp?” This TechTip will hopefully make the process of creating a multi-state shape object clearer. Start a blank EasyBuilder Pro Project and locate the rectangle shape tool… Set properties for our shape outline… (note that “Filled” is un-ticked at the moment). Draw the outline frame on the design window… Copy and past the outline frame and make a solid filled shape by ticking “Filled” and setting appropriate colours… Select the Outline frame… Click on “Shape”… … which will Continue reading TechTip: Using the Shape Library with Weintek HMI

TechTip: Using Weintek HMI to Print a label on a Zebra Printer using Free Protocol

In this TechTip we’ll be looking at printing a label to a Zebra printer by sending the ZPL string to the com port or Ethernet port on the HMI. Zebra printers are increasingly popular in production and packaging and are highly configurable and able to print barcodes, QR codes, Data matrix codes etc. (for reference, the printer used in this demo was a Zebra GK420t.) This isn’t intended to be a lesson in the ZPL language, but we will run through the label string used for our demo: The code we’ll use for this label is below: We can preview Continue reading TechTip: Using Weintek HMI to Print a label on a Zebra Printer using Free Protocol
