Programmable logic controller (PLC) or distributed control system (DCS)? Two different options for control. Many different reasons to use one or the other.
This survey, organized by Bill Lydon, director of PLCopen North America, looks to bring some clarity to the choices.
The philosophical and technical debate has lasted for years and continues to become more complicated. Development of the Open Process Automation Forum’s O-PAS Standard requires IEC 61131 and/or IEC 61499 programming standards from the PLC industry.
Machine builders and system integrators are invited to share experiences, clarify issues, define tradeoffs and voice concerns or thoughts by participating in this survey.
