RT-301: Capabilities of Distributed LabVIEW Real-Time

Eric Nielsen’s Real Time blog did a good job of hitting the major strengths and benefits of any system based on a controller running a Real-time operating system. Here I’ll get into a little more depth, specifically for the capabilities t...


It's Easy Being Green

Kermit the Frog once sang, “It’s Not Easy Being Green.” Sorry Kermit, we at DMC disagree - it's actually pretty easy. We know “going green” is trendy right now, but it’s something DMC has focused on for awhile....


Selecting the Right Machine Vision Software and Platform

One of our many areas of expertise at DMC is developing and integrating machine vision systems. Our focus is on offering the most effective solution for the application; we are hardware/vendor independent and are not tied to any platform. When select...


Siemens vs Allen-Bradley: Function Blocks

Siemens and Rockwell Automation are two giants competing in industrial automation technology today. Rockwell (aka Allen-Bradley) seems to be more popular in the US market, but Siemens has a larger international customer base. A cursory Google search ...


Successful Implementation of Siemens' SiMotion Shaftless Drive Standard

In many industries, shaftless drive technology has replaced the old mechanical drive systems. Instead of using mechanical gearing to force one axis on a machine to follow another one, servos are used. The servo technology reduces many of the flaws of...


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 r...


Introducing LabVIEW Object Oriented Programming to your Toolbox

The concept of LabVIEW Object Oriented Programming (LVOOP) has been around for a number of years now, but has consistently been one of those areas that seemed to have to high of a learning curve to justify learning “just because”. Luckily...


PLC Analog IO Troubleshooting Tips

When commissioning or troubleshooting PLC inputs and outputs (IO), the analog signals are often the most difficult. First, analog IO almost always has to be scaled to convert the raw signal to useful process values. Also, there are many wiring and ex...


PLC Troubleshooting

We are frequently asked to work on PLC systems for clients that we did not develop. The job could be troubleshooting an issue or adding a new feature to the system. Working with unfamiliar code has its own unique challenges, although we take pride in...


"Indirect Addressing" in Step 7 Basic v10.5 SP2

For those of us who appreciate and harness the power of indirect addressing in Siemens S7 300 and 400 level PLCs, we were sad to hear that this functionality was not supported in the same way for the new Step 7 Basic software for S7-1200 PLCs. As ...
