provides a specification for suppliers to meet evolving requirements for digital process control systems by having a common standard through which users can be assured of compatibility, interworkability, interconnectability, interoperability and interchangeability of the devices they choose. defines the requirements for FBs to provide control, and to facilitate maintenance and technical management as applications, which interact with actuators and measurement devices
