<7. System Delivery Precautions>
● Forms of Delivery for System Expansion
The forms of delivery for a system expansion job involving adding a new FCN-500
or FCN-RTU to an existing system is the same for delivery of a new system.
● Forms of Delivery for System Modification
For jobs involving modification of an existing system, engineering is usually done
using the FCN-500 or FCN-RTU and CPU module of in-house equipment as the
existing hardware including its CPU module is usually not available for development
and testing purposes. Thus, the form of delivery normally includes only the Logic
Designer control application, which is to be downloaded to the existing FCN-500 or
FCN-RTU from the site PC.
In this case, it is necessary to perform retain data setup and Resource Configurator
definitions required for the system modification on the site system.
Although it is also possible to deliver retain data specified during user acceptance
test, we do not recommend doing so as it requires the same procedure described in
“● If Both FCN/FCJ and System Card of In-house Equipment Are Used before
Migration“ of Section 5.1.4, “Precautions of Migrating Testing from In-house
Equipment to Target Equipment.”
The required form of delivery depends on the nature of the job and the conditions at
the end of user acceptance test.
Before delivery, consider carefully what items are to be delivered and in what forms.
For a system modification job, it is especially important to consider how system
delivery should be done to minimize adverse impact to the existing system.
