Siemens Simatic S7-400 - S7 Connections

Load 󹪝rmware
You upload the 󹪝rmware 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 Con󹪝g > 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 󹪝rmware status is
displayed.
If there is no 󹪝rmware loaded on the CP 440, the display shows " - - - - ". This can occur, for
example, if a 󹪝rmware update was canceled. The original 󹪝rmware is deleted prior to the
cancellation. You have to upload 󹪝rmware to the module before it can be restarted.
4. Click the "Find File ..." button to select the 󹪝rmware to be loaded (header.upd).
Result:
The version of the 󹪝rmware you select is displayed under "Status of selected 󹪝rmware:".
5. Click on the "Load Firmware" button to start uploading to the CP 440. You are prompted for
con󹪝rmation. The upload procedure is canceled immediately if you click on the "Cancel"
button.
Result:
The new 󹪝rmware 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 󹪝rmware update is completed.
Note
Before the basic 󹪝rmware is deleted from the module, the CP 440 checks the order number
of the 󹪝rmware to be downloaded in order to ensure that the 󹪝rmware is approved for the
CP 440.
Power Failure During Firmware Uploading
If there is a failure when the 󹪝rmware is being uploaded, the process must be repeated. The
module then has the state "CP 440 without module 󹪝rmware".
