Connecting Custom Applications to the Factory Floor

Connecting Custom Applications to the Factory Floor

DMC has expertise in both industrial and PC-based software development. In other words, we do a great deal of projects involving PLCs; but we also write plenty of complex PC-based apps. But my personal favorites are projects that combine the two. We’re seeing them more and more. Don’t get me wrong, off the shelf solutions are great, and should be used wherever they make sense. But sometimes they don’t fit all of the requirements our customers need. Here are some examples I&r...

New York Office Update

New York Office Update

Live from New York, it's DMC! We expanded to the Empire State this year, along with opening an office in Houston, to create growth opportunities and to better serve our customers. Although I actually moved from the Chicago office in April, the office really started to feel up-and-running when the rest of the team joined me over the summer. We’ve had two office locations so far – the first at 5th Ave and 27th St, and our new space at 8th Ave and 36th St...

DMC is Expanding to New York City

DMC is proud to announce the opening of a new office in New York City! As a central hub to the metro area, New Jersey, Connecticut, and upstate markets, we view this new location as a wonderful opportunity for growth in all of our service offerings. While we will be officially opening the doors in late April, we are already working to support customers in the area.  For this latest office expansion, DMC is targeting the Flatiron neighborhood in Manhattan. Our address will be centrally lo...

Automating Siemens S7 and SiMotion Tasks Using C# .NET

Automating Siemens S7 and SiMotion Tasks Using C# .NET

Siemens offers useful tools for accessing both Simatic and SiMotion projects programmatically, in the form of registered COM Type Library DLLs. These tools offer many exciting possibilities (well, it does if you're like me, and get excited by things like automating automation tools). If you have Simatic Manager installed, the following DLLs are registered with it: S7hcom_x 1.0 Type Library - The default location on my laptop is C:\Program Files (x86)\Siemens\Step7\S7BIN\S7HCOM_X.DLL) S...

Automation Redundancy Using ICONICS WebHMI Solutions

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...

Siemens PLCS, Networking, and More--DMC at the SITEC 2011 Conference

I recently had the opportunity to attend my first Siemens technical conference. The conference, called SITEC, took place May 16-20 in Atlanta, GA, and Kristie Shea and I represented DMC. SITEC is Siemens’ technical conference where solution partners like DMC, distributors, and internal Siemens staff learn about the latest Siemens software and hardware technology solutions. I had a great time seeing what's new and upcoming in the automation world, as well as meeting the people behind th...

Using Siemens S7-300 PLCs to Report System Errors

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...

Object Oriented Programming in Siemens and Allen Bradley PLCs

Object Oriented Programming in Siemens and Allen Bradley PLCs

Since their conception PLC programs have been founded on simple programs. RLL (Relay Ladder Logic) and IL (Instruction List) commands have dominated PLC programs since PLCs first came to market in the 1970s. However in the past few years automation requirements have grown more complex and demanding. This has in turn led to PLC manufacturers beginning to include some higher level programming concepts in their software packages. What exactly have they added? And what does it mean for your manufact...

Winter Fun At DMC

Winter Fun At DMC

A lot of us here at DMC like to get outdoors and stay active, even during these brutal Midwestern winters. This Saturday 5 DMC employees including myself braved the cold to spend a great day out at Alpine Valley ski resort. Jody Koplo, Jesse Batsche, Jessica Mlinaric, Eric Nielsen and I all had a blast learning how to snowboard, even though some were more succesful than others! Here is our own Jesse Batsche, tearing up the terrain park: Eric Nielsen wisely opted to avoid the physical pain...

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...

Siemens S7 PLC Troubleshooting

Siemens S7 PLC Troubleshooting

Once you are familiar with their capabilities and methodologies, Siemens PLCs have the potential to make controls programming quicker and easier than ever. With support for function blocks, text-based programming, libraries, and user defined types, Siemens lets developers attack problems with a much more object-oriented approach than traditional ladder logic programming. But for programmers and technicians less experienced with the Siemens line of PLCs, The S7 and S5 product lines often seem ove...

Remote Machine Monitoring–Connecting to a Modbus Network with Java and Jamod

Remote Machine Monitoring–Connecting to a Modbus Network with Java and Jamod

For a recent project, I had an interesting challenge. It involved a (relatively) simple control system, with an Allen Bradley MicroLogix PLC, and 30 or so inputs and outputs. The challenge was that the customer wanted to be able to access (and potentially control) live machine data from anywhere on their network, while buying as little hardware or software as possible. After a bit of research I came up with the following solution: The only entryway to the data that was available with no a...
