Firmware Updates for CPU 312C (6ES7312-5BF04-0AB0)

Description:

When updating the firmware, always update to the latest version available for the product and its respective article number. The previous versions of the firmware are only intended as backup to allow a downgrade to the original version. Until now this is not known to have been necessary in any case.
The respective latest version of a CPU firmware is valid for all versions of that article number.

Please note:
During the firmware update the actual values will be lost. If you require them, please save these values before starting with the FW update with the function "Copy RAM to ROM...."


The update can either be performed via Micro Memory Card or online:

1. Micro Memory Card:

Requirements for creating an operating system update card:

  • Micro Memory Card with at least 4 MB storage capacity
    article number 6ES7953-8LM31-0AA0
  • STEP 7 V5.1 SP2 or higher
  • PC with external PROM programmer (6ES7 792-0AA00-0XA0) or 
    FieldPG / PowerPG  for programming the Memory Card

Creating the 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 executing: "File/S7 Memory Card/Delete" in Simatic Manager.
  4. Program the operating system by selecting "Hardware/update operating system" in SIMATIC Manager,
    then select the target directory and "open" the CPU_HD.UPD file to start the programming process.
  5. Programming of the operating system update card is completed when the message "The firmware update for the module with the article number 6ES7312-5BF04-0AB0 was transferred successfully to the S7 memory card" appears on the screen.

To update the operating system:

  1. Power OFF the power supply (PS) of the rack in which the CPU is inserted
  2. Separate the controller from the communication network
  3. Insert the prepared operating system update card into the CPU
  4. Power ON the power supply (PS) of the rack in which the CPU is inserted
  5. The operating system is transferred from the Micro Memory Card to the internal CPU FLASH EPROM; during this process, all indicator LEDs on the CPU are lit (FRCE, RUN, STOP, SF, BF)
  6. The operating system update will take approx. 2 minutes; completion is indicated by a slowly blinking STOP LED => prompt for overall reset by the system
  7. Power OFF the power supply (PS) and insert the Micro Memory Card intended for operations
  8. Power ON the power supply (PS); the CPU automatically performs an overall reset and is then immediately operational.
  9. The time has to be synchronized prior to reconnecting the controller to the communication network.

2. Online:

Prerequisites:

  • An online update of the firmware is possible with STEP 7 V5.3 or higher
  • The target module in the station - whose firmware is to be updated - must be accessible online 
  • In the module, an MMC (Micro Memory Card) must be inserted as buffer memory
  • The unpacked files with the current firmware version must be present in the file system of your PG or PC:

    BG_ABL.UPD
    CPU_HD.UPD
    KOMP_1.UPD

    A folder must only contain the files of one firmware version.

To update the firmware:

  1. Start STEP 7 and switch to HW-Config
  2. Open the station with the CPU to be updated
  3. Highlight the CPU
  4. Select the command "Target System > Update Firmware"; the command can only be activated, if the highlighted CPU supports the function "Update Firmware"
  5. In the dialog "Update Firmware", use the "Find" button to select the path to the firmware update files (*.UPD)
  6. Once you have selected a file, information about the module suitable for the file and the firmware version required is shown in the lower portion of the dialog "Firmware Update"
  7. Click on the button "Execute"; STEP 7 will check whether the file selected can be interpreted by the module; if the answer is positive, the file will be loaded into the CPU; if the operating mode of the CPU must be changed for this, you will be prompted via dialogs; the CPU will then autonomously perform the firmware update
  8. With STEP 7, check whether the CPU successfully starts up with the new firmware (read the diagnostics buffer of the CPU).

Update V3.3.16 (6ES7 312-5BF04-0AB0)

The CPU version named above does not contain any functional innovations.

Information on STEP7 dependencies and upward compatibility:
STEP7 V5.5 or higher is required for configuration of these CPUs. When using the TIA Portal, V12 or higher should be used, where possible.
iMap V3.0 SP1 or higher is required for the CBA configuration.
Configurations with earlier STEP7, iMap and TIA versions are compatible with later releases.

The following changes are effective with FW update V3.3.16:

  • There are no more sporadic CPU connection interruptions, for example when reading data records using the HMI service. This is because 0x80Cx is no longer automatically repeated in the case of temporary (data record) error messages and the return value is reported back directly to the client.
  • The module status of DP slave slot 2 is displayed correctly in the online view in STEP 7.
  • The stability of the status block environment has been enhanced.


Update V3.3.12 (6ES7 312-5BF04-0AB0)

The above CPU version contains no new functions.

Information on STEP7 dependencies and upward compatibility:
STEP7 V5.5 or higher is required for configuration of these CPUs. When using the TIA Portal, V12 or higher should be used, where possible.
iMap V3.0 SP1 or higher is required for the CBA configuration.
Configurations with earlier STEP7, iMap and TIA versions are compatible with later releases.

The firmware update V3.3.12 provides the following corrections:

  • After a CLR instruction, set and reset commands no longer sporadically result in the setting or resetting of bit operands.
  • When monitoring logic operations sequences with an “O” instruction (Or), RLO views no longer change.
  • Connection interruptions with online functions will no longer sporadically result in the defect with Z1=F012.
  • For acyclic data exchange with the SFBs 52 and 53 in case of a high communication load the defect status with Z1=E800 is no longer occasionally triggered, instead the temporary RetVal 80C3 is signaled at the SFC.
  • Time synchronization of the master no longer leads to isolated cases of defects with Z1= F012 or Z1=8392.
  • Following a memory reset request, for example, because a project which does not match the CPU is saved on the MMC, formatting of the MMC through switch operation now functions again as described in the manual.


Update V3.3.11 (6ES7 312-5BF04-0AB0)

The above CPU version contains no new functions.

Information on STEP7 dependencies and upward compatibility:
To be able to configure this CPU your require STEP7 V5.5 or higher.
For the CBA configuration you require iMap V3.0 +SP1 or higher.
Configurations with earlier STEP7 and iMap versions are compatible with later releases.

The new firmware version V3.3.11 provides the following corrections:

  • When monitoring blocks online with the calls and path specification of a block already opened for monitoring, the previously occurring defect with Z1=4305 will be prevented and a negative checkback signal generated instead.


Update V3.3.10 (6ES7 312-5BF04-0AB0)

The above CPU version contains no new functions.

Information on STEP7 dependencies and upward compatibility:
To be able to run this CPU your require STEP7 V5.5 or higher.
For the CBA configuration you require iMap V3.0 +SP1 or higher. Configurations with earlier STEP7 and iMap versions are compatible with later releases.

The new firmware version provides the following corrections:

  • In the case of a message buffer dump with a large number of transmission messages that would lead to an abortion of the message dump by the connection partner, e.g. because of lack of memory space, the connections will no longer get hooked up and a Defect with Z1=98C6 will no longer occur.
  • The retentivity backup in the case of power off/on has been stabilized, so that the previously occuring very sporadic Defect with Z1=F00F no longer occurs.
  • With TIA version V11 the loading of blocks which contain an ANY-Pointer with length 0 will no longer lead to Defect of the CPU with Z1=F012..
  • During online monitoring of several blocks with TIA version V12 the previously occuring Defect with Z1=7141 after the third block is now prevented; instead, a negative checkback will be generated.
  • An abortion of the communication connection during Block Status could previously cause the sporadic Defect with Z1=F004. Connection monitoring has now been improved.
  • Rapid successive calls of the SFB 52 (reading of data records) will no longer cause the sporadic Defect with Z1=E801.
  • Repeated loading of the user program on MMC with a simultaneously open topology display will no longer cause the Defect with Z1=F014.
  • Disturbances on the line during job reception from a connection partner will no longer cause the sporadic Defect with Z1=700A.

Update V3.3.8 (6ES7 312-5BF04-0AB0)

The above CPU version contains no new functions.

Information on STEP7 dependencies and upward compatibility:
To be able to run this CPU your require STEP7 V5.5 or higher.
For the CBA configuration you require iMap V3.0 +SP1 or higher.
Configurations with earlier STEP7 and iMap versions are compatible with later releases.

Firmware update V3.3.8 provides the following corrections:

  • COS values of very small numbers (>=0 and <3.8518597E-34) are now output correctly with value 1.
  • AUF DB/DI indirect no longer causes sporadic opening of an incorrect DB.
  • In the case of a block upload or download the CPU will no longer sporadically go to Defect with Z1=F01A.
  • Communication abortions while the communications functions are running will no longer sporadically lead to Defect with Z1=F012.
  • In the case of block calls of the SFCs 82..84 with REQ=0 (RET_VAL=7000), BUSY will not be signaled with TRUE anymore.
  • The accuracy of the square root calculation "SQRT" has been improved.
  • When the 24V supply voltage is switched on, the module will no longer generate a short negative pulse (approx. -11V / 5-7 ms) at the voltage output.

Update V3.3.7 (6ES7 312-5BF04-0AB0)

This firmware version contains the following functional enhancement:

  • SFC 109 PROTECT: New Mode 12, with which protection level 3 can be program-activated without password authentication (even with a password, no read/write accesses to the CPU are then possible); see also Product Information / Entry ID 61757603.

 
Information on STEP 7 Dependencies and Upward Compatibility:
For the operation of this CPU, STEP 7 V5.5 or higher is required.
For the CBA configuration, iMap V3.0 SP1 or higher is required.
Configurations with earlier STEP 7 and iMap versions are compatible with later releases.

With firmware update V3.3.7, the following changes become effective:

  • With devices that have been in operation for approx. 500 days, retentively configured timers no longer sporadically hang or run infinitely
  • To prevent retentivity losses with event ID 16# 4580 or 16# 6523, the MMC connection during power OFF/ON has been optimized
  • When using SFC 23 DEL_DB without an existing DB, the defect Z1=F833 no longer occurs 
  • Synchronization errors resulting in a STOP of the CPU no longer lead to the extremely rare defect Z1=F004 
  • Aborting a block transfer no longer sporadically leads the to defect Z1=4131
  • Connections of the CPU to a PLC are now completely terminated in case of connection loss 
  • When using clock flags, the three adjacent flag byte addresses are no longer affected 
  • The performance of uploading blocks to programming devices has been optimized 
  • HW versions with boot loader A25.7.5 and below now always permit the loading of blocks encrypted with block privacy.
