Once the drawings have been created, AutoCAD Electrical has a report that allows the export of I/O addresses and descriptions to be imported directly into the PLC program. It also understands the terminals connected to each I/O point. Commonly, the software is produced before the hardware design, and we need to ensure that they are communicating and working off the "same page."ĪutoCAD® Electrical has a utility that allows the PLC I/O design to happen via a spreadsheet and then imported to create the drawings, including ladders, I/O module address, and descriptions. Hardware and software engineers need to collaborate just as Controls and Mechanical engineers do. Sometimes one engineer or designer does the hardware design, and another does the software (PLC/HMI/etc.).
The hardware design explains the physical wiring and descriptions, and the software design makes it happen. As Controls Engineers, we are all aware that design involves both hardware and software, typically including PLC logic.
