WinCC Comfort/Advanced HMI Heartbeat
Furqan Ayub

WinCC Comfort/Advanced HMI Heartbeat

WinCC Advanced provides a way to monitor the heartbeat of the HMI through an area pointer called coordination word. PLC can monitor this life bit and find out when the HMI gets disconnected. This blog shows you how to monitor the HMI life bit on a Siemens PLC. Create a data block variable of type Word called wCoordinationWord and open HMI connections in Portal. After you select the HMI connection that is linked to your PLC, select the area pointer tab. Enable the Coordination area point...

Downgrading Siemens PLC Projects: From V15 to V14 SP1

Siemen’s TIA Portal provides quite a few useful features that make it very easy to update and maintain code. Updating projects from one version to the next is as easy as opening the project in the newer version of Portal. However, there are times when you want to revert a project to an older version of TIA Portal, something that Portal cannot do. That’s where TIA Portal Openness can help. For those looking to revert projects from V15 to V14, this post will outline the pr...

Custom Data Logging using a Siemens Comfort Panel and VB Script
Caleb Stoll

Custom Data Logging using a Siemens Comfort Panel and VB Script

I recently worked on a project that required the use of data logging. However, the formatting of Siemen's data logging was not ideal for this implementation. So, I made my own version of data logging using Visual Basic scripts on my Comfort Panel that create and append to a CSV file. One of the first things to think about is where you want to store these logs. For Comfort Panels, you can access the onboard USB drive and the SD card slot via VBScript. You can also access a networ...

Siemens S7 Graph Tips and Tricks
Nikhil Holay

Siemens S7 Graph Tips and Tricks

SIMATIC S7 Graph is used for programming sequence logic in a graphical, flow chart representation. For those of us who have been programming sequences in ladder logic or SCL, Graph presents an alternative method that includes some built-in functionality. For those that haven’t used Graph (and maybe those who have!), I’ve put together some tips and tricks to help you develop quickly and efficiently. Pre/Post Instructions Pre and post-instructions run cyclically, before and after...

Employees Lead Company Improvements During FedEx Day 2018

DMC recently took a break from day-to-day tasks to participate in one of our favorite company traditions, FedEx Day. Routine work on hold, our offices still brimmed with life and projects while everyone worked on whatever they wanted.  FedEx Day is always an opportunity for fun, learning, and collaboration, with only two catches: the project must in some way help to improve the company, and it must be deliverable by the end of the day. This year, our employees took on everything ...

6 Things You Should Know When Commissioning a SIMATIC S7-400 PLC

Your code compiles, hardware config is all set, but you can't get rid of the red lights on the 400H system. Check the following before pulling out your soldering iron and green LEDs.    1. Are the rack switches correct? If you have no idea what I'm talking about, good news, this might be it! Take the second PLC off Rack 1 and look for an exposed switch on the back. Change it so it says "Rack 1" instead of "Rack 0". The default setting of the sw...

10 More DMC Engineers Pass the Siemens Certification Exam

DMC has a lot of Siemens Certified Engineers. In fact, we have the most in the United States. As we continue to grow, so does our number of Siemens experts. After a recent Siemens Global Certification exam in the Chicago suburbs, we are proud to add ten more certified engineers to the list bringing our current total to 39! Even though our engineers are already smart, they spent four days training for this Technical Certification in the SIMATIC Technology areas of S7 PLCs, SIMATIC HMIs, a...

Using an S7-1500 PLC as a Modbus RTU Slave

Need to make data available from your 1500 PLC to a Modbus RTU master? As long as you have a Modbus RTU capable serial communications adapter module, setting up a Modbus RTU server is pretty simple. Communications Adapter Since S7-1500 PLCs don't typically come with onboard serial communication ability, you'll need to use an adapter module that supports the Modbus RTU slave protocol, with a port interface that meets your system connection requirements. See below for two ...

DMC Engineers Serve up a Siemens S7 Powered DrinkBot

Working together for over a year, a group of DMC engineers built our very own DrinkBot. We developed it during a FedEx Day and improved the DrinkBot over a second FedEx Day. DMC's DrinkBot finally made its debut at the Siemens Automation Summit 2017. As happens in the development process, we slowly improved the DrinkBot over time. We started displaying it at career fairs in Colorado to help grow the team. We also took it to events in New York, Houston, Seattle, and Manufacturing...

Leveraging Siemens MultiUser Engineering for TIA Portal

With Siemens TIA Portal V14, a great new tool for PLC and HMI development called MultiUser Engineering was released. MultiUser Engineering allows multiple developers to access a server project through local sessions and quickly and seamlessly merge updates to PLC or HMI code such as function blocks, user-defined types (UDTs), WinCC Comfort or Advanced screens, and more. DMC has been using the MultiUser tools with great success, and I'd like to share a few insights with y...

Efficient SCL Development in TIA Portal V14

With the recent release of TIA Portal V14 and V14 SP1, several new additions have been added to increase the efficiency and organization of code written in SCL (structured control language). Recently, I have been using many of these new features while writing code in SCL and wanted to share them with you. We will start by defining SCL and its uses in programming, then we will compare ladder to SCL, next we will discuss inline SCL networks, Regions and Region Synchronization, and will finish b...
