Configuring and Parameter Assignment the CP 440
5.6 Firmware updates
Load firmware
You upload the firmware update with the aid of the CP 440: Point-to-Point Communication,
Parameter Assignment interface.
Proceed as follows:
1. Switch the CPU to STOP mode.
2. Start the parameter assignment interface:
In SIMATIC Manager: File > Open > Project > Hardware Config > double-click on CP 440 >
select the "Parameter" button.
3. Select the Options > Firmware Update menu command.
Result:
If a connection can be established to the CP 440, the current module firmware status is
displayed.
If there is no firmware loaded on the CP 440, the display shows " - - - - ". This can occur, for
example, if a firmware update was canceled. The original firmware is deleted prior to the
cancellation. You have to upload firmware to the module before it can be restarted.
4. Click the "Find File ..." button to select the firmware to be loaded (header.upd).
Result:
The version of the firmware you select is displayed under "Status of selected firmware:".
5. Click on the "Load Firmware" button to start uploading to the CP 440. You are prompted for
confirmation. The upload procedure is canceled immediately if you click on the "Cancel"
button.
Result:
The new firmware is loaded into the operating system memory of the CP 440. "Done" shows
progress in bar-graph form and as a percentage. The module is immediately ready for use as
soon as the firmware update is completed.
Note
Before the basic firmware is deleted from the module, the CP 440 checks the order number
of the firmware to be downloaded in order to ensure that the firmware is approved for the
CP 440.
Power Failure During Firmware Uploading
If there is a failure when the firmware is being uploaded, the process must be repeated. The
module then has the state "CP 440 without module firmware".
