Operation

Code Download

Download via CONFIGURATION port

A downloading tool in the control builder software can be used to download configuration files to the controller. The downloading tool first verifies that a valid configuration file exists for the controller. Next, a dialog box asks if you want to set the controller to Program mode in preparation for downloading. If the configuration file is verified to be valid, then the existing controller configuration in the controller’s memory is deleted before the new configuration is downloaded.

A download dialog box appears on the PC after a successful file download to the controller. Upon completion of the download, a command is sent to set the controller to Run mode.

Download via floppy disk

The optional floppy disk drive allows the user to download configuration files stored on a floppy disk to the controller using the operator interface. The DISK UTILITIES display provides menu selections to load and store controller configuration files. The controller must be in the Program mode in order to load configuration files in the controller. Successful download status and failures are indicated at the operator interface display. Downloading restrictions are noted in Table 16.

File uploads

Controller configuration files, setpoint profiles and recipe files can be uploaded for storage and archiving to a floppy disk as well as to the PC. Using the PC, the Upload function is accessed from the Communications pull-down menu of the control builder. At the operator interface, the DISK UTILITIES display contains menu selections for storing the files to disk.

Code Download

Controller firmware upgrade

In order to implement new features for controller operation or correct any software bugs, an upgrade of the controller firmware may be required. The User Utility software program contains the code download utility that allows a newer version of the controller firmware to be loaded into the CPU.

CAUTION

Before performing a code download:

Perform a backup of all controller configuration files.

Be certain that the controller does not show a low battery (LoBatt) diagnostic.

After the download is successful reload the controller’s configuration files, recipes, profiles and schedules.

Controller code download in the user utility

A PC running the user utility is connected to the controller’s Configuration port. The code download utility is accessed from the Maintenance pull down menu. Refer to the UMC800 User Utility User’s Guide and on-line help for more details on performing the download.
