Note 1 - Controller files can be downloaded with the controller in Run Mode with the Mode switch set to
Run/Program, but not with the switch set to Run/Lock.
The download from the host processor is directed to an area of controller memory separate from that used
for running the controller, and hence has no effect on the active process.
The host signals the controller when the download is complete, and requests a configuration validation test
and report from the controller. The controller then checks the new database and compares it to the current
(running) database. Using the test report as a basis, the host then presents the operator (user) with a dialog
box containing a set of choices: begin using the new database with no cold start, use it with a re-start, or
abort the download.
For downloading procedures, refer to the Operator Interface User Manual #51-52-25-108.
Configuration Upload
Controller configuration files, setpoint profiles, and recipe files can be uploaded for storage and archiving
in a PC and/or to a disk in the Operator Interface. Using the PC, the Upload function is accessed from the
Designer Software.
For details of uploading configuration items, refer to Designer Software and Operator Interface manuals.
Firmware Download
Firmware Download provides a mechanism to upgrade the firmware in your CPU and Scanners. It is
available in Program or Program Locked modes only. Specific instructions are provided with the upgrade
files.
