Yokogawa CS3000 DCS is installed in our refinery. 2 out of 4 operating stations (HIS) are unbranded systems, so we are trying to replace these systems with branded ones. To isolate the last station we put one terminating resistor on Vnet 1, but Vnet 1 failed to recover. We tried this on all stations but failed.
Remember, we are trying to do this job online, and in the past this was our usual practice to isolate systems.
If anyone has experience/expertise then please guide us.
