  3. 3. [File Name or Event] Emerson Confidential 27-Jun-01, Slide 3 Applications are modeled using function blocks which may be distributed between field devices. FF function block application process is consistent with IEC 61804 Process Industry Function block Function block execution may be synchronized through system management - based on each device having a common sense of time. USER LAYER PHYSICAL LAYER COMMUNICATION STACK Function Block Application Process
  4. 4. [File Name or Event] Emerson Confidential 27-Jun-01, Slide 4 Mode and Status, foundation of distributing control Engineering Unit Value + STATUS attributes of input and output parameters Target and Actual attributes of Mode parameter BLOCK_ERR Parameter
  5. 5. [File Name or Event] Emerson Confidential 27-Jun-01, Slide 5 Mode Possible modes:
  6. 6. [File Name or Event] Emerson Confidential 27-Jun-01, Slide 6 Mode  TARGET, ACTUAL, PERMITTED  TARGET is the desired mode  ACTUAL is the actual mode.  PERMITTED are the permitted mode  You can not use a non permitted mode  If the resource block is out of service, all blocks go to Out of Service  If the Transducer Block is in OOS, the status will be Bad, Out of Service
