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: 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
