The EM 253 is a positioning expansion module for the Simatic S7-200 PLC for precise control of microsteppers and intelligent servo drives. A separate controller independently of the main CPU handles positioning tasks.
The module outputs directional-response-path and speed information to the PLC's power section over an integrated pulse-train interface. It is also equipped with signal inputs for direct position sensing via position switches. Positioning tasks are configured using a graphics-supported assistant in Micro/WIN, which also generates the control commands for the user's program. All parameters for the positioning EM are stored on the CPU It is possible to store as many as 25 positioning profiles, which can then be called in the user program when needed.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
