<7. System Delivery Precautions>
7.4 Delivery for System Modification
For a system modification job, it is important to download the modified application to
the operational site system without adversely affecting its operation. Besides the
general precautions described below, some systems may require additional
precautions to be observed.
Review the state of the existing system, and add other work items as required.
7.4.1 Pre-Delivery Preparation and Application Backup
As the CPU module of in-house equipment used during user acceptance test is not
included in the system delivery, it is necessary to rebuild the system on-site. To
prepare for that, perform pre-delivery preparation and application backup as
described earlier for delivery of a new system.
7.4.2 System Delivery
Save the control application in Logic Designer into a zwt format file for delivery.
If the job includes Duolet applications, deliver the required files.
7.4.3 Preparation for On-site Installation
Before starting on-site installation, save the current state of the existing system.
As described in Section 7.2.1, “Pre-Delivery Preparation” and Section 7.2.2, “Control
Application Backup,” download the boot project and source, save retain data,
backup data on the on-board flash memory of the FCN500 or FCN-RTU and back
up the control application in Logic Designer.
