Have you ever been disappointed in the data logging options available on your Basic panel? Ever wished it were easier to set up logging directly to a database? Or perhaps you've wanted to set up some simple simulation or test sequences without mo...
When asked if we work with a particular technology here at DMC, my answer is always "yes". PLC, Embedded, Test and Measurement, Business Logic: we do it all and more. WinCC OA (OA) is the spiritual analogue to that philosophy in SCADA fo...

For a couple of recent projects I needed to transfer a few bytes between Siemens PLCs. I had used PUTs and GETs in the past, which I find very useful for sending large amounts of data. But if I only need to send a few bytes or speed is critical, sett...
Creating popup windows on HMI pages enhances the interaction between the operator and the machine. The creation of popup windows in Automation Studio involves many other important aspects of making an HMI more dynamic such as formatting layers on pag...
Have a need to make data available from your S7-1200 PLC to a Modbus TCP Master (or SCADA)? Luckily, this is easy to setup. This will be short and sweet. Siemens provides two Instruction blocks for setting up Client/Server Modbus TCP connections &...
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 una...
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...
