If the CP responds to the download start, but the download operation does not finish properly,
it could be that:
● The same address has been assigned more than once on the plant bus.
● The load on the plant bus is too high.
Note
If a CP does not respond to a load procedure via the configured MAC address, load the CP
again via the imprinted address.

How to perform a firmware update of the CP 443-5 Extended
Preparation
● Compare the type and version of the modules you are using with the information in the
document
PCS 7 Released Modules.
● If you need to replace the CP, contact your Siemens representative.
Requirements for the firmware update
● STEP 7 V5.3 or higher is installed on the programming device or PC.
● The update file for the firmware update is available on the programming device / PC.
● MPI cable
Note
Ensure the following for the firmware update of the CP 443-5 Extended:
● If you want to connect devices that operate with PROFIBUS standard DPV1 to your
PCS 7 system after conversion, you might have to replace the hardware (e.g. CP type:
6GK7 443-5DX03-0XE0 with firmware V5.1 or higher).
● This hardware requires special device drivers.
For information on generating the device drivers, refer to the
Process Control System
SIMATIC PCS 7; Programming Instructions, Creating Blocks for PCS 7 documentation.
Preparing for the firmware update
1. Make sure that the required firmware update files are available on the programming device
or PC.
Files for the firmware update are available on the Internet. You can find information on this
in the section "Hardware Updates".
2. Switch off the power supply (PS) of the rack where the CP is inserted.
3. Use an MPI cable to establish a direct connection between the MPI interface of your
programming device or PC and the PROFIBUS interface of the CP.
4. Switch on the power supply of the rack and the programming device or PC.
