The Industrial Internet of Things (IIoT) is making direct access to process data at all levels more necessary by the day. End users, DCS and PLC manufacturers require process device data for control, monitoring, problem reporting, and inventory management simultaneously. There is a limit to the amount of data traditional fieldbuses like PROFIBUS PA can handle due to data packet […]

PA networks are designed to be operated as process  “islands” within a larger PROFIBUS DP controlled network. The total network could consist of several of these “islands” all controlled by a single PLC/DCS. Each PA “island” starts with the DP/PA coupler which acts as the PA master and consists of several PA devices on a segment. Each “island” could be […]
