B&R Automation Studio: Create Popup Windows on HMI Pages

Creating popup windows on HMI pages enhances the interaction between the operator and the machine. The creation of popup windows in Automation Studio involves many other important aspects of making an HMI more dynamic such as formatting layers on pages, controlling and using the HMI display in program code, and manipulating the statuses of HMI elements. If you are new to creating HMI pages with Automation Studio, then you can learn a lot from this video. Learn more about DMC's B&R Aut...

Refreshing Datasources in Iconics’ Genesis64 HMI/SCADA Development Software
Sudeep Gowrishankar

Refreshing Datasources in Iconics’ Genesis64 HMI/SCADA Development Software

Datasources in Genesis64 are defined within the GridWorX64 application to cache data for display and use in the HMI. My experience with datasources has been as a link between a SQL server database and Genesis64. However, while developing an application that contained numerous datasources (40+), I ran into an issue that rendered the application unusable. This blog post describes the issue and a workaround. The Problem: Refreshing datasources with a time trigger takes an increasingly long amou...

Review of the Iconics Genesis64 HMI/SCADA Development Software

Over the course of the last few months, I have delved deep into the Genesis64 HMI/SCADA development software package by Iconics while working on a standardized solution for recipe editing in manufacturing lines. Overall, it is a competitive option when fast development time and web access are valued.  One of the features that enables fast development is the ability to use data from a SQL server database, a standard in many industries. Genesis64 uses an application called GridWorX64 Serve...

VBScript Strings and Siemens HMI Smart Tags:  'Play nice, you two!'
Grant Anderson

VBScript Strings and Siemens HMI Smart Tags: 'Play nice, you two!'

String concatenation. If a programming language supports strings, it's going to support concatenating them. The means of doing so are usually straightforward and often times involve a simple library call or even a one character operator such as "+" or "&." Internal string representation typically follows one of two paradigms: either the string uses a unique terminator to signal the end of the string, or it includes within the type itself the length of the n...

Getting Young Kids Interested in Technology

I'm always trying to get my daughters, ages 8 & 5, interested in what we do here at DMC. It's a challenge because I have a hard enough time explaining what DMC does to someone I meet at a cocktail party, never mind a couple of young kids. However, I recently had two great experiences with them that actually piqued their interest. The first was a trip to Legoland in Carlsbad, California. In addition to Miniland USA, Land of Adventure and other fun rides, there also is a Lego Factory T...

Automation Redundancy Using ICONICS WebHMI Solutions

There are many good options for automation and controls redundancy out there. Here is an example we just recently used in the field. The customer specified a requirement of complete redundancy for all IT, networking, and HMI components of one of a large-scale manufacturing line. The system architecture we chose incorporated thin-client HMIs with server virtualization, off-the-shelf ICONICS redundancy solutions, dual KEPware OPC servers, a custom .NET service, and automatically backed-up SQL data...

Read Command Line Parameters from VBA

Recently, I needed to read a command line parameter within a VBA code (it's for an Iconics SCADA application, but I developed it with Excel VBA which is essentially the same). It doesn't sound like a big deal but there were a few not-so-obvious tricks that I thought were worth sharing. I started with the simplest solution using a "GetCommandLineA" Windows API function from kernel32.dll. It was supposed to return a pointer to the c...

Iconics, VBA, VBScript, and Writing to OPC Tags

Iconics, VBA, VBScript, and Writing to OPC Tags

Background DMC has often had to download a high number of values from a SQL server to an OPC server. In the past, this had usually been done with VBA code that was called from an Iconics HMI screen. The code looped through about 600 tags in less than a minute. The VBA code was always executing locally (on the same PC) as the OPC server it was writing to. For a particular application, the HMI architecture switched to using WebHMI. Therefore, the VBA code needed to be converted to VBScript f...

Using Siemens S7-300 PLCs to Report System Errors

The Siemens S7-300 line of PLCs has about a million great features integrated into the programming environment. After I recently inherited a PLC project where some (many) of these were not implemented, I thought it might be a good idea to do a recap on some of the more useful functions Step7 has to offer us. By far one of the most useful, and sadly underutilized, capabilities available to us from the Step7 environment is the “Report System Errors” utility. This utility, when activ...

Siemens S7-1200 PLC communicates through Sinaut MD720-3 cellular modem

Many consumers, including myself, have tapped into the ever-growing functionality of mobile internet. Many people leverage this infrastructure for their mobile phone. Others are beginning to use WiMAX connections for their PCs. Not to be out-done, PLCs are also capable of communicating through wireless data plans. DMC just finished the proof-of-concept phase in a project using the new Siemens Simatic S7-1200 PLC and Siemens Sinaut MD720 GPRS GSM cellular modem. We were able to successfully se...

Redundant Control Systems: Siemens S7 400H Series PLC and WinCC

There are certain control systems, such as in nuclear power plants and airplanes, that cannot be disabled or shut down, even momentarily, because of the threat to people’s lives. In these applications, a redundant control system must be in place to take over instantaneously if the primary system fails. I recently deployed one such redundant control system for train tunnel ventilation at a major international airport. The system's main objective is to control, reduce, and help exting...

Communication between Siemens HMIs and non-Siemens controllers

Communication between Siemens HMIs and non-Siemens controllers

Ever wanted to use those very nice looking Siemens touchpad HMIs with a third party controller Siemens doesn't officially support? On a recent project I was presented with the following scenario: a customer already had several Siemens touch-screen HMIs in stock, and wanted to use one to help operators control an Elau motion controller. Of course to do this I had to get the HMI and controller to talk to one another. The HMI understood about 20 different protocols — everything from Allen...

Vijeo Designer Version Control with Tortoise SVN

I was working with Vijeo Designer 5.0 on a recent project and, overall, found it rather enjoyable to work with. Vijeo Designer is the Schneider Electric / Telemecanique programming software for the Magelis XBT-GT HMI's along with several other SCADA platforms. The creation of variables let me organize my I/O into logical folders, the alarm setup was intuitive and let me create specific groups en mass, and the page designer let me create an object with pretty much any look and feel that I ...

Populating Iconics/GraphWorX32 Drop-down list (Statefield) from VBA

If you have never heard about Genesis32 SCADA package from Iconics, this is the right time to learn more about it before we continue. I shall wait right here... Good, now you know what I am talking about. We'll talk about GraphWorX32, this is HMI graphical display application. One of the control available in GraphWorX32 is drop-down list (Statefield). This is pretty cool drop-down menu, but values on the list have to be hardcoded during screen design and can't be updated at runtime...
