Updating Firmware Of I/O Modules - Siemens SIMATIC PCS 7 Operation And Maintenance

Update in a redundant system
You can update the firmware of the interface modules during operation for H-systems with
redundant interface modules.
If the update of the active IM is made via PROFIBUS DP, the restart automatically triggers a
switchover between the two IMs. The second IM then needs to be updated too. The update
must be performed separately for each IM. If the ES or the PG is connected to the Profibus
master system directly, the two IMs are updated one after the other as of PCS 7 V7.0SP1
(STEP 7 V5.4SP3) and IM 153-2BAx1 as well as IM153-2BAx2, IM153-2BA10 and IM153-
2BA70. For the update of a redundant ET 200SP HA (IM155-6 PN) by the CPU using S7
routing, once a station is selected, both IMs are automatically updated one after the other.
NOTICE
Before you begin the update, make sure that both IMs are in redundant mode.
• Both ends of the PROFIBUS DP or PROFINET cable are plugged in.
• Both IMs are plugged in.
• The IMs and modules are fault-free.
Otherwise, the station will briefly fail after the restart instead of switching over.

Updating firmware of I/O modules

Example: HART modules
A firmware update can be performed via HW Config for the HART modules 6ES7331-7TF01-
0AB0 and 6ES7332-8TF01-0AB0.
You can find the requirements and steps in the section titled "Firmware update through HW
Config" in the "ET 200M distributed I/O device HART analog modules"
(https://support.industry.siemens.com/cs/ww/en/view/22063748) manual.
Example: SM 331 AI 6 x TC
The firmware can be updated via HW Config for electrically isolated analog input module SM
331; AI 6 x TC (6ES7331-7PE10-0AB0). You can find further details in manual "SIMATIC
S7-300 S7-300 Module Data"
(https://support.industry.siemens.com/cs/ww/en/view/8859629).
