We have many installations of DVC6200F foundation fieldbus type positioners.
Many times for various kinds of problems we have replaced PWB of DVC.But,recently in one positioner while replacing PWB it was observed that after replacing PWB the device remains with visitor address of 254.
Due to that, we are unable to commission that device on segment.We are not able to change the adddress of the device and tag both as it is in visitor address range.
Our control system is Honeywell experion PKS R400.8 .
We have tried to change the address through HART475 communicator but even with that we are not able to enter that particular device.
Please provide technical solution for the same.
