Which Firmware File to Select

Dear All,

Presently I've downloaded the firmware update file for upgrading the firmware of CPU 417-4H PN/DP 6ES7 417-5HT14-0AB0 to latest version. Hereby is the downloading link:

https://support.industry.siemens.com/cs/gb/en/view/109474703

Now I got a little confused regarding the selection of the file required for Firmware upgrade. In the downloaded .exe file when I extracted that it gave 05 files with .UPD extension.

Kindly guide me which file shall I have to select for installation the latest Firmware.

Regards

OmKris

Hello,

from your link:

• Program the operating system by selecting the following in Simatic Manager: "PLC/Update AS OS", select the target directory and start the programming process by opening the file CPU_HD.UPD.

 Hi Christoph,

I have a PG with me and want to do the firmware transfer via that one. Then can you guide me how to proceed with that PG?

Hello,

the procedure is described in you link!

Description of replacement scenario

Both CPUs must have the same firmware version in an S7-400H. If one CPU of your S7-400H fails, order a new CPU with the same order number. It will be delivered with the latest firmware version. This firmware version may be higher than the firmware version of the CPU being replaced. In this case, you must downgrade the new CPU to the older firmware version.

You have two options for the downgrade:

1. using the memory card
   (see description …..)
   
2. using the online functionality as described below:

Description of the operating system update with a memory card

Requirements for creating an operating system update card:

• S7 memory card
• Flash 8 MB (order number 6ES7 952-1KP00-0AA0) or greater
• STEP 7 with product version V3.1 or higher
• Programming device or PC with external prommer for programming the memory card

Procedure for creating an operating system update card using STEP 7:

• Download the required CPU file
• Unzip the file with a double-click on the file name
• Delete the memory card with: "File/Delete/S7 Memory Card" in Simatic Manager.
• Program the operating system by selecting the following in Simatic Manager: "PLC/Update AS OS", select the target directory and start the programming process by opening the file CPU_HD.UPD.
• The operating system update card is programmed when the standard mouse pointer appears again.

General procedure for an operating system update:

• Power OFF at the power supply (PS) of the rack in which the CPU is installed.
• Insert the prepared operating system update card into the CPU.
• Power ON at the power supply of the rack in which the CPU is installed.
• The operating system is transferred from the memory card to the internal FLASH EPROM.
• During this transfer, all the LEDs on the CPU are lit (INTF, EXTF, FRCE, CRST, RUN, STOP). The operating system update takes about 2 minutes and is completed when the STOP LED on the CPU flashes slowly => memory reset request from the system.
  NOTICE:
  The self-test is started immediately after the update and can take several minutes, depending on the memory configuration.
• Power OFF at the power supply and possible insertion of the memory card intended for the operation.
• Power ON at the power supply.
  The CPU automatically performs a memory reset and is then operational immediately.
• Set the time after the successful operating system update.

Description of the operating system update in RUN

As a general rule, any firmware update in RUN can only be from one firmware version to the next higher firmware version. A downgrade is not possible in RUN. See also the notes on the respective version-specific description.

Procedure for automatic firmware update:

Initial situation: Both CPUs are in redundant operation. Redundant operation

1. For CPU access protection with password: Select a CPU of the fault-tolerant system in SIMATIC Manager and select the menu command PLC > Access authorization > Setup. Enter the CPU access password.
2. Select one of the two CPUs either via Simatic Manager -> Project or HW Config. Do not use the menu command "Accessible nodes" in Simatic Manager.
3. Select the menu command "PLC > Update firmware"
   A wizard is started that can automatically update the firmware on both CPUs.

The complete update description and alternative solutions are described in the Fault-tolerant S7-400 H Systems system manual under "Firmware update in RUN mode".

Hello ChristophD,

Can you explain me the probable reason for Firmware crash or troublesome! Actually the End Users are asking a common question that "WHY FIRMWARE PROBLEM HAS OCCURRED/ WHY ARE YOU UPGRADING THE FIRMWARE"??
