15.4 System update SIMATIC Drive Controller

You can check the firmware versions of the individual components with parameters. The
versions of the DRIVE-CLiQ components and those of SINAMICS Integrated (or of the control
unit) may differ.
Note
DRIVE-CLiQ components with higher firmware versions are backward compatible and can also
operate with DRIVE-CLiQ components with lower firmware versions.
Automatic firmware update
You can use parameter p7826 to influence the response for automatic firmware updates of
DRIVE-CLiQ components.
With the automatic firmware update, the firmware version of the DRIVE-CLiQ components is
checked against the firmware version of SINAMICS Integrated (or the control unit) and if
necessary updated upon each power up. This means power up can take a few minutes
longer.
The following settings are possible:
• p7826 = 0: Upgrade and downgrade deactivated
• p7826 = 1: Upgrade and downgrade (factory setting)
• p7826 = 2: upgrade only
A parameter change does not become effective until the next drive system power up.
Where Safety Basic, Extended and/or Advanced Functions are enabled, the system checks
whether the parameter for automatic firmware updates p7826 = 1 is set. Otherwise, the
following message is output: F01664 (SI CU: No automatic firmware update).
15.4 System update SIMATIC Drive Controller
The system software of the SIMATIC Drive Controller is necessary for basic operation of the
controller and contains components like BIOS, drivers and configuration data.
Thus, the system update is different from a firmware update, with which, for example, the
functionality of the SIMATIC Drive Controller can be expanded. It is only necessary to update
the system software if Siemens Service & Support or your Siemens contact person has
recommended it.
The version of a system update that has been performed can be determined at the following
places:
• in the TIA Portal in the CPU diagnostics using the option "Online & Diagnostics" and the
secondary option "Diagnostics > General" under "Drive Controller information"
• in the CPU Web server on the web page "Diagnostics" in the "Identification" tab under
"Drive Controller Info"
• in the exported diagnostic buffer of the CPU
If "---" is displayed as the version, there is no system update installed.
