1) Infield bus system, IOP detection is different from HART system.
2) IOP will occur only for input e.g. transmitters.
3) One probability is there (which is most common) that your transmitter is under-ranged or PV value fluctuates highly (on wither ends). Being s digital system you will not receive IOP(-) in FF system.
4) Check for alarms and run integrity test (via PRM) and check if any of the internal blocks like AI or Transducer block or Resource Block is going to OOS (Out of service or Manual Mode).
5) Additional Check :
Check if you are receiving CNF error. If it comes then you may reset the transmitter by removing the power or isolating it from Loop.
This shall resolve the error. If not then you need to replace the transmitter.
Hope this helps.
