5.6 Firmware updates
5.6.1 Subsequent Loading of Firmware Updates
Introduction
The communication processor is shipped with basic firmware preinstalled. You can enhance
functionality and eliminate errors by downloading firmware updates to system memory of
communication processor.
Subsequent loading of firmware updates takes place with the CP 441: Point-to-Point
Communication, Parameter Assignment programming interface.
Requirements
The prerequisites for loading firmware updates are:
● You must create a valid project under the hardware configuration and upload it to the
CPU before you can update the firmware of the communications processor with the
programming interface
● The instructions accompanying the firmware update always detail the destination
directories for the files.
The "..\CP440.nnn" path always identifies the firmware version.
Firmware download
You upload the firmware update to the CP 440 with the aid of the CP 341: 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.
