Firmware Update In Run Mode - Siemens SIMATIC PCS 7 CPU 410-5H System Manual

Special functions of the CPU 410-5H

9.6 Firmware update in RUN mode

9.6 Firmware update in RUN mode
Requirement
You operate the CPU 410-5H in a fault-tolerant system. Both Sync links exist and are
working. There are no redundancy losses. (The REDF LED is not lit.)
Note any information posted in the firmware download area.
Note
I/O bus fault
There may be no I/O bus faults, for example, a faulty IM153-2, because the update may
result in station failures otherwise.
Procedure for automatic firmware update
Initial situation: Both CPUs are in redundant operation.
1. For CPU access protection with password: In SIMATIC Manager, select a CPU of the
fault-tolerant system, then select
"PLC > Access Rights > Setup" from the menu. Enter the CPU access password.
2. Select one of the two CPUs using either SIMATIC Manager -> Project, or HW Config.
Do not use the "Accessible nodes" menu command in SIMATIC Manager.
3. Select the "PLC > Update Firmware" menu command.
A wizard is started that can automatically update the firmware on both CPUs.
Alternative procedure for progressive firmware update
Follow the steps below to update the firmware of the CPUs of a fault-tolerant system in RUN:
1. For CPU access protection with password: In SIMATIC Manager, select a CPU of the
fault-tolerant system, then select
"PLC > Access Rights > Setup" from the menu. Enter the CPU access password.
2. Set one of the CPUs to STOP using the ES.
3. Select this CPU in HW Config or in SIMATIC Manager in your STEP 7 project.
4. Select the "PLC -> Update Firmware" menu command.
The "Update Firmware" dialog box opens. Select the firmware file from which the current
firmware will be downloaded to the selected CPU.
5. In SIMATIC Manager or HW Config, select the "PLC > Operating Mode > Switch to" and
select the "With altered operating system" check box.
The fault-tolerant system switches the master/standby roles, after which the CPU will be
in RUN again.
