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.

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
