One of the great, and underused, features in TIA Portal is the Network Topology tab of "Devices and Networks." It can enable you to accomplish a number of advanced tasks while simultaneously providing more in-depth network diagnostics. Today, I want to quickly show you how you can use Network Topology to configure a MRP-based Ring Network in TIA Portal. Why Ring Topology? There are many reasons why one might consider using a ring topology for your network. The most common one is ...

With the release of Siemens TIA Portal V14, and even more recently V14 SP1, DMC has been able to develop larger, more complex applications within one development environment which used to require two or more development environments (ex. TIA Portal with SIMOTION SCOUT for motion control applications). While many improvements have been made recently to allow for more technically sophisticated controls systems to be developed exclusively within TIA Portal, DMC has run into some limitations. ...

PackML, or Packaging Machine Language is a programming standard defined by the Organization for Machine Automation and Control (OMAC) and by the International Society of Automation's Technical Report 88. It is meant to be a convenient project template that can be used in the discrete manufacturing of many products, from bottled drinks to wrapped candy. I thought it would be helpful to assemble this guide of PackML basics for anyone who is getting started with this standard. PackML has ...

Recently, I had the privilege of speaking at the 2017 SITEC National Conference. I shared my experience as the lead developer on the Siemens Open Library and demonstrated how to utilize and contribute to the Open Library. Per Siemens, the SITEC Conference aims to keep engineers and specialists up-to-date on the latest products and technologies from Siemens by providing, "specific, effective and customized training along with a certification path to ensu...

DMC recently held another one of our favorite company-wide traditions... FedEx Day! On FedEx Day, everyone in the company takes a break from their day-to-day tasks and works on a project that they think will improve DMC. It's a great opportunity to collaborate with people we don't normally work with, develop new skills, and have fun. It's called a FedEx Day because the planned project must be delivered by the end of the day. With five offices and more employees than ever, the...

Back in 2011, DMC attained the most Siemens Certified Engineers in the United States when eight of our employees passed the Siemens Global Certification or Recertification exams. We have grown as a company since then, and so have the number of Siemens experts at DMC!  DMC is proud to continue to have the most Siemens Certified engineers in the United States. Thirty-one DMC engineers have met all of the requirements for the Global Technical Certification in the SIMATIC Technology areas...

DMC has often encountered a scenario where a customer wants to have a motor drive follow the position of an external encoder. However, a regular 1500 PLC does not allow you to directly gear to an external encoder; this functionality requires a 1500T PLC. The T-series processors allow much more complex motion control, but are also more overhead for simpler projects. As it turns out, with a little creativity, it is possible to gear to an external encoder using a regular 1500 PLC. While you can&...

DMC recently provided remote support for one of our customers. We made critical updates to their PLC code as they were commissioning their machine internationally. Unfortunately, our client didn’t have TIA Portal software available at the time. They were afraid that this made it impossible to download the new version of the code to the PLC in the field. Fortunately, Siemens offers the SIMATIC Automation Tool as a free download (just sign up for an account first) on the...

Look at you! You’re enterprising and a real go-getter! You’ve been working on an S7-1500 and can’t get your project to connect and download, but it’s not a problem. You know that all you need is a quick factory reset and you should be good to go.  Only this time, the factory reset doesn’t work.  Updating Firmware No fear. You notice that there is some new firmware available on the Siemens Industry Support Website. Way to go! No need to freak ...

Ever wish you could create a project with optional hardware modules? Or add hardware in the field with any programming? Configuration Control within TIA Portal allows you to configure hardware modules and even I/O network objects to be optional so that a user can, at run-time, choose what hardware should be used.

For anyone who has spent much time working with the SIMATIC S7-400H, it becomes quickly apparent that the devil is often in the details. You find that there are many small settings and 'tricks' that you uncover while setting up redundancy, redundant Modbus communication, redundant communication interfaces for I/O, configuring hardware, etc., that you need to get things running. Sometimes those small details are hard to catch. In the words of my wise colleague Lillian Walker, "The re...

Version 1.4 has just been released for the Siemens Open Library. This includes a V13 SP1 update and also contains a Portal V14 beta release. Explore and download the Siemens Open Library at openplclibrary.com. V13 SP1 Update 9 contains the following updates: Added dynamic fonts to all HMI faceplates for variable size HMIs Updates to several Supplementary blocks Added official blocks for SIMOCODE and SIRIUS Soft Starter Resolved bug in fbIO_AnalogInput when using RTDs Fixed ...

It's back! When V13 SP1 was first released, one of the features I was most excited about was the ability to multiplex arrays of custom UDTs on a PLC using a simple index tag on an HMI. This feature allowed me to use a single faceplate or screen to display or modify data from multiple objects by simply changing a single tag. I was so excited, I even wrote a blog post about it then! Unfortunately, it was a feature to be short lived and, due to some unexpected consequences, mysteri...

Have you ever wanted to read current, torque, or power data from your Siemens variable frequency drive (VFD) without having to change your telegram or communication configuration? Well, you are in the right place! The guide below will walk you through how to acyclic read or write any drive parameter with your Siemens PLC.  Acyclic communication to a Siemens drive may seem like an impossible, obscure language, so the goal of this article is to translate it into something more understandab...

The Siemens Open Library marked its 1000th download this week. The free, open source function block library was launched in June 2016 through a partnership between DMC and Siemens. The library aims to be a resource for consistency, usability, and faster development for the Siemens community. The library has continued to evolve since its initial release. Updates have included the inclusion of all of DMC’s library, which included a large number of Function Blocks and Function calls. Addit...

DMC recently discovered that there are some unique settings associated with configuring a Siemens G120 Variable Frequency Drive (VFD) with extended safety functionality using the onboard terminals. This blog is meant to be a guide for this type of configuration to avoid troublesome and difficult-to-diagnose issues. Hardware Setup In this particular situation, we used an S7-400H PLC to control a CU240E-2 VFD. The S7-400H can be configured with two CPUs in a fully redundant PLC setup, b...
