Yokogawa performs upgrade work based on the following standards.
Node number
I/O nests in the old FCS are replaced with node units in the upgraded-FCS. In this case, “A new
nodenumber=anoldnestnumber+1”shallbeconguredasshowninthegurebelow.This
is a measure to be taken to make slot positions of an I/O card (module) equal before and after
upgrading the FCS. The I/O slots of the FCU after upgrade are equipped with communication
modules (*1) for node unit.
*1: Those are EC401, EC402, ANT401, ANT411, etc.
