5. Download this file to the CPU. The new CPU now has the same firmware version as the
previously used CPU.
6. Now connect the fiber-optic cable for the CPU of an H system.
Switch the system to the "Redundant" operating mode by starting this CPU.
You can then upgrade both CPUs of the H system to the latest firmware in the "Run" state.
Difference of the firmware update to a non-redundant system
Following the actual firmware update, a self-test starts automatically for the H-system. This
function may take several minutes. This time period depends on the amount of load memory
(size of the inserted memory card) and the amount of working memory.

3.3.4 Updating an interface module
3.3.4.1 Updating an interface module (IM)
Introduction
The interface modules (IM) ) are the interface to the PROFIBUS DP in PCS 7.
Preparation
● Compare the type and version of the interface modules you are using with the information
in the document
PCS 7 Released Modules.
● If replacement of the interface module is required, contact your Siemens representative.
● A firmware update is possible for some interface modules. You will find the procedure in
the section "How to perform a firmware update of an IM (Page 40)" below.
Update capability of interface modules or couplers downstream from interface modules
You can update the firmware of the following components (interface modules or couplers
downstream from interface modules):
Components Order Number As of firmware version
IM 153-2 6ES7 153-2Bx00-0XB0
IM 152-1 6ES7 152-1AA00-0AB0 V2.02
Ensuring Availability
3.3 Hardware update
