DESCRTPTION: When the operating system is updated, it should always be updated to the latest version that is available for the relevant order no.. The previous versions of the operating system can be used for backup purposes, allowing you to downgrade to the original version, although as far as we are aware this has never been necessary.
The latest version of a CPU operating system is valid for all releases of this order no..

Prerequisites for creating an operating system update card:

• Micro Memory Card with 4 MB storage capacity
  (order number 6ES7953-8LM20-0AA0
• STEP 7 V5.1 + SP2 or higher
• PC with external PROM programmer (6ES7 792-0AA00-0XA0) or 
  PG720/740 with adapter (6ES7 798-0BA00-0XA0) or
  FieldPG/PowerPG  for programming the Micro Memory Card

Procedure for creating an operating system update card with STEP7:

1. Download the desired CPU file.
2. Unpack the file by double-clicking the file name.
3. Delete the Micro Memory Card by choosing "File/S7 Memory Card/Delete" in Simatic Manager.
4. Program the operating system by choosing in Simatic Manager "PLC/Update Operating System", select the destination directory and start programming by opening the CPU_HD.UPD file.
5. Programming of the operating system update card is completed when the message "The firmware update for the module with the order number 6ES7 317-2AJ10-0AB0 was transferred successfully to the S7 memory card" appears on the screen.

Executing the operating system update:

1. Switch OFF the power supply (PS) of the rack in which the CPU is located 
2. Isolate the PLC from the communication network
3. Insert the prepared operating system update card in the CPU
4. Switch ON the power supply (PS) for the rack in which the CPU is located
5. The operating system is transferred from the Micro Memory Card to the internal CPU flash EPROM. During this time all the CPU's LEDs will be on (FRCE, RUN, STOP, SF, BF).
6. The operating system update is completed after about 2 minutes and is indicated by the slow flashing of the STOP LED on the CPU => prompt for overall reset by the system
7. Switch the power OFF at the power supply and insert the Micro Memory Card required for operation.
8. Switch ON the power supply. The CPU automatically does an overall reset and is then immediately ready for operation.
9. Before connecting the PLC to the communication network again the clock must be synchronized.

2. Online:

Prerequisites:

• On-line updating of the firmware is possible with STEP 7 V5.3 and higher.
• The module to be updated must be located in a station that can be reached on-line.
• An MMC must be inserted in the module.
• The files with the latest firmware version must be available on the file system of your programming device (PG or PC).
  One folder may only contain the files for one firmware version.

To update the operating system:

1. Start STEP 7 and switch to HW-Config.
2. Open the station with the CPU to be updated.
3. Earmark the CPU.
4. Select the menu option "Target system > Firmware update". The menu option can only be activated if the selected CPU supports the function "Firmware update".
5. In the opened menu option "Firmware update" use the "Search" button to select the path to the  firmware update files (*.UPD).
6. When you have selected a file, you will be told in the lower part of the "Firmware update" dialog field for which module and from which firmware version onwards the file is suitable.
7. Click the "Execute" button. STEP 7 will check whether the selected file can be interpreted by the module and - if the result is positive - load the file to the CPU. If the operating mode of the CPU has to be changed for this purpose you will be asked to perform this action. The CPU will then perform the firmware update on its own.
8. Check with STEP 7 (read CPU diagnostic buffer) whether the CPU successfully starts up with the new firmware.

Update V2.6.10 (6ES7317-2AJ10-0AB0)

The above CPU version does not contain any new functions.

Note on STEP7-related dependencies:
To operate this CPU you require STEP7 V5.4 + SP2 or higher.
For CBA configuration you require iMap V3.0 + S7AddOn V3.0 SP2 or higher.

• If in the setting "OB85 Call during I/O access error --> Only with coming and going errors" a missing DP slave whose addresses are stored in the process I/O image is disabled, the SF LED will now extinguish in addition to the BF LED.

• In the case of an ACCU1 value of , the instruction "RND" will now supply the correct value .

Update V2.6.5 (6ES7317-2AJ10-0AB0)
