  Abstract: A large-scale application of usage-centered design to industrial automation software is described. Step 7 Lite is an integrated development environment (IDE) for PLC programming, enabling automation specialists at diverse skill levels to engineer and program solutions to automation problems. This winning entry in the 2001 Performance-Centered Design Competition (original and demo at STEP 7 Lite) was submitted jointly by Siemens AG and Constantine & Lockwood, Ltd. It describes the design of the hardware configuration facilities, a critical portion of the IDE, along with other key performance-support features. The design objectives and rationale for the solution are presented along with a previous version for comparison. Results from usability testing and task analysis are briefly reviewed.
  Keywords: performance-centered design, usage-centered design, performance support, industrial automation, PLC programming, hardware configuration
