Product Life Cycle Support (PLCS) is an ISO standard developed for the maintenance and through-life support of complex products using a state-of-the-art open and rich data model. Led by Eurostep, the data model of the PLCS standard was designed to enable a digital thread and digital twin even before these concepts became well established. Implementing PLCS doesn't only provide an immediate digital thread capability but also adds new functionality to already existing software and processes.
