Siemens S7 PLC Programming

DMC worked with an automotive manufacturer to upgrade their HVAC test chamber controls from an outdated system that utilized an Allen Bradley PLC5 PLC with a Wonderware HMI. DMC's solution converted the test sequence controls and user interface to a LabVIEW application and the device controls to a SIMATIC ET200 CPU to align with other test chambers in their facility.  This project was a great opportunity for DMCers all around to work together as we collaborated across our Manufacturing...

DMC modernized and consolidated a control system used to purify water for a dual cycle, gas turbine power plant. Three separate control systems utilizing a diverse set of hardware and software were all combined into a single TIA Portal V15 Project. DMC provided a turnkey solution, handling the hardware purchase and install in addition to software. We worked with the client about nine years ago to make different additions and upgrades to the original system. The switchover from the old system to the...

DMC worked with Siemens to develop a robust and modular brewing template project geared towards craft brewers. To decrease future development time, DMC developed tools using Openness and SiVarc to quickly create and link control modules on a PLC and HMI. DMC implemented this solution, including custom additions, for Founders Brewing, one of the most prominent craft breweries in Michigan, in their new Detroit brewpub. 

DMC worked for a transportation company to upgrade their train car HVAC controllers from an outdated Simatic S5 platform to an S7-1200 PLC. DMC’s solution included new features such as an HMI panel, data logging, and flexible implementation ability.

DMC developed an Azure-based IoT waste management solution for monitoring trash compactor fullness.

DMC worked with a biological research firm to upgrade a highly customized legacy SCADA application and a Think & Do PC-based controller to WinCC Advanced combined with a space-saving ET 200SP PLC. DMC replicated existing functionality while expanding operator usability and data manipulation options through customized WinCC Advanced interaction.

DMC programmed a Siemens S7-1200 PLC to communicate with servo controllers, using a serial interface. The serial communication was used to allow the operators to change the servo setpoints from a remote HMI.

DMC worked with a confectionery company to retrofit a high-speed packaging machine with a Keyence camera vision system. The camera detects bad, incomplete, or missing product and triggers an S7-300 PLC system to reject the product prior to packaging.  

DMC used the PackML State Machine architecture to program a packaging machine for a food and beverage company. The machine coordinates the motion of several servo motors that together package a variable number of products at high speeds. This project was part of the customer’s larger initiative to revamp their packaging machines.

DMC worked with a Houston-based plastics processing company to perform a controls retrofit on a bagging machine which was outfitted with legacy control hardware that was no longer supported by the original manufacturer. The retrofit utilized Siemens S7-1200 PLCs and Comfort HMI.

DMC utilized a Siemens S7-1200 to program the controls for a prototype household appliance with two stepper drives. Typically, the application is geared toward embedded hardware. However, DMC utilized the low-cost PLC to implement a flexible solution to fit the client’s budget and schedule constraints. This made it possible for the client to invest less money to build a functional prototype which can be used to judge market demand.

DMC created and tested a library of Siemens function blocks for S7-300 PLCs using Simatic Manager that can be used to communicate with a  manufacturer's 6 axis Cartesian robot. The function blocks are now provided by the manufacturer so that end users can easily communicate with the robot and execute standard commands.

DMC programmed a machine to fill small bottles of liquid at rates up to 1,000 bottles per minute, using several coordinated axes to transfer bottles between sections of the machine. Our role was to program and commission the motion aspects of the project, as well as to update existing code to use best practices with Siemens PLCs.

DMC developed the PLC program for a pilot scale coal burning power plant, as well as a SCADA system using Siemens WinCC 7.2. The SCADA system included an HMI designed with the end user in mind, as well as custom logging scripting.

DMC programmed and commissioned a Siemens Wireless Safety system to safely operate and monitor two-story tall glass doors for a Silicon Valley, CA-based technology company's flagship retail electronics store.
