Sir,We are using Honeywell EPKS R511 System PID(controller) with AO (of positioner)of ND9000f positioner.It is control on host.On loss of FF communication and after recovering the positioner does not hold last value always.IO option in AO is not selected(fault state to value is unchecked).Also after power recycle the valve does not return to last value.( fault state on restart is unchecked).What is non volatile SP value of AO block.?Where can we change NV value of SP?
