Source Code Protection For Your SIMATIC S7-1200 PLC in TIA Portal

Source Code Protection For Your SIMATIC S7-1200 PLC in TIA Portal

From time to time, we'll run across situations where a client believes it is necessary to lock down code on a PLC. In some cases, there may be valuable intellectual property they would like to protect. In others, its purpose may be to prevent unauthorized modifications to safety-related code, or activation of disabled options. There may also be cases where it is necessary to interlock a PLC program to a specific memory card or CPU, especially in cases where there may be multiple, similar (bu...

Troubleshooting Your Siemens SIMATIC S7-1200 Timers

Troubleshooting Your Siemens SIMATIC S7-1200 Timers

I've done a lot of PLC programming over the last few years. Siemens, Rockwell, Beckhoff, Mitsubishi, Panasonic... if it's IEC61131-3 compliant, I've probably written a few rungs on it. However, I recently ran across an interesting problem that completely stumped me. I was doing a quick test on an S7-1200 PLC (programmed in TIA Portal V13) where I needed to perform a non-time critical operation approximately once a second within a re-usable FB. The two rungs that confounded me and ...

WinCC Professional Popups
Jimmy Condon

WinCC Professional Popups

SyntaxHighlighter.all(); For a recent project using WinCC Professional V12, I needed to have a pop up window that could change based on the screen window that the operator clicks (motor, VFD, valve, etc.). The popup also needed to have its location change based on where the screen window was that the operator clicked. To implement the popup, I added a screen window to the starting screen. I did not assign any of its properties: I gave it a visibility animation based on an internal tag...

VB Script to Save an SSRS Report as a PDF

VB Script to Save an SSRS Report as a PDF

Reporting is almost a universal requirement for new projects coming into DMC these days. As part of an HMI we developed for a customer we also installed SQL Server Reporting Services (SSRS) on a Siemens PLC. This is used to generate reports for production batches run on that PLC. The customer desired these reports to be in PDF format, which after some investigation was easy to do with SSRS. A little background on SSRS... SSRS is a web application that generates nice graphical reports from SQL...

Extracting Log Data from a Siemens PLC Using a .NET Client
Jack Cosgrove

Extracting Log Data from a Siemens PLC Using a .NET Client

I had the opportunity recently to work for a client who wanted to extract log data from a Siemens WinAC PLC using a C# .NET client. The application was archiving software that would run when another software component encountered an error. Log data was assembled from a variety of sources in the system stack, including the Siemens PLC. In order to keep the PLC's Step 7 code independent of this diagnostic logging, I used the Siemens WinAC ODK. The WinAC API exposes two interfaces, IPLC and ...

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...

PID with a Siemens S7-1200 PLC

PID with a Siemens S7-1200 PLC

A few weeks ago I had the chance to experiment with serial communications using a Siemens S7-1200 PLC outfitted with a CM1241 (RS-485 module). Due to the limited number of projects we've had using the 1200 line of PLCs, this was an office first. And while it was very straightforward, it was still a learning experience. Recently I had another chance to be DMC's S7-1200 pioneer - this time using the S7-1200's PID blocks, and luckily, not involving death by dysentery, cholera, or sna...

Siemens S7-1200 Serial Communication

Siemens S7-1200 Serial Communication

Today, I found myself setting up some simple point-to-point serial communication on a Siemens S7-1200. For the current application, I was writing a simple function block to broadcast data to a Red Lion serial slave display, but there are a variety of situations in which you may need to do to this, such as communicating with a VFD. While there are many people in this office who do this regularly with other Siemens PLCs, it was the first time for any of us on an S7-1200, so I though...

The Basics of Siemens S7 PLC I/O Addressing

Are you a new user of Siemens PLCs a and wondering what terms like "process image" and "peripheral address" mean? What does the "P" in "PIW" stand for? Are you an experienced user and are too embarrassed to ask? Or, maybe you are like me and just need refresher every once in a while? Fortunately, the Siemens support website has a great article that explains these different ways to access I/O for Siemens S7-300 and 400 PLCs. Here are some summary t...

DMC Helps Connect the Siemens User Community with an Interactive New Event

What was the Siemens Connect Event? The Siemens Connect Event was an hour-long networking event held at the 2011 Siemens Automation Summit. Likened to "speed networking," the Connect Event was initiated as a fun and interactive way for Siemens Solution Partners and users to connect on a personal rather than business level. Attendees participated in "power" meetings which were facilitated by complimentary iPads and an application (app) built specifically for this event. ...

Siemens S7-1200 Analog IO

If you find yourself working with Analog IO on the Siemens S7-1200 for the first time, you may wonder how and where to start.  Here are some basic tips for working with Analog IO on this PLC platform.  For the purposes of this blog, I will focus on implementing 4-20mA inputs and outputs, but the concepts should apply to other signal types as well. Configuring Analog Input/Output Models: Open the Device Configuration for the PLC.  Add your module, then configure each channel...

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...

DMC Presents at the 2010 Siemens Automation Summit

What was the best part of my trip to Charlotte, NC last week? - Watching the Blackhawks Stanley Cup game 6 on a massive screen in the NASCAR hall of fame after the Siemens award ceremony. Very surreal... and totally awesome! Yes, Siemens really knows how to put on a great event. Last week was the 2010 Siemens Automation Summit, held in beautiful Charlotte, NC. The Siemens Automation Summit is a conference that specifically focused on the end users of Siemens automaton products. It is a gre...
