Dear All please help! what's wrong? is it the CPU 315-2 PN/DP V3.2.3.? OR the newly bought Micro Memory Card? this is what happened: 1. I bought new MMC 6ES7953-8LJ31-0AA0 512KB for that CPU 2. I used TIA Portal V13 to download a very simple latch program to cpu (see attachment "simple_latch_program.PNG") 3. when i click download, load preview is ok (see attachment "when_click_download.PNG") but when click load an error occurred stating "There is not enough memory available for download to the device. Main (OB1) could not be loaded" (see attachment "click_load.png") I've done the following: 1. I put CPU in stop mode, then execute memory compress, then MRES the CPU, then do download but the same error occur 2. I restart CPU, still the same error 3. I format memory card "6ES7953-8LJ31-0AA0" using the USB Prommer, wherein the last saved OB1 is there and of course it will be deleted but when i try to download new OB1 the same error occured 4. I noticed in the memory, that in the Load memory RAM: the size in bytes of Free:, In use:, and the Total: are all zero and it indicates that the Load Memory RAM + EPROM is n.a. (see attachment "memory.PNG") 5. the CPU is communicating (see attachment "communicating.PNG") Thanks and hoping for your replies.. ------------------------------------------------------------------------------------------ Attachmentattachment.zip (1043 Downloads) |

hello ChristophD Thanks for your reply, 1. I shutdown the power of CPU and then turn on again, then the display on diagnostic buffer has a message: "illegal module: replace module and reset memory" (see attachment: diagnostic_buffer_after_shutdown_then_turnON_CPU.png) 2. Then I download a simple latch program again after the same error pops-out, I've done MRES on TIA portal and check the diagnostic buffer (see attachment: diagnostic_buffer_after_download.png) 3. the "stop LED" is NOT blinking Ive done additional activities: 4. when MMC is inserted to prommer - the MMC is detected (see attachment: when_mmc_inserted_to_prommer.png) - prommer can read MMC'c properties (see attachment: prommer_can_read_mmc_properties.png) - i copy my simple latch program from OB1 (see attachment: copy_OB1.png) - and paste it to program blocks (see attachment: paste_to_program_blocks_using_prommer.png) - that OB1 is successfully copied (see attachment: OB1_successfully_copied.png) my assumption: I think the MMC is working fine bcoz it is detected using prommer 5. when I put that MMC to my CPU 315-2 PN/DP V3.2.3. - it does not detect the MMC (see attachment: MMC_not_yet_inserted_AND_inserted.png) may i ask if my assumption is correct?, does my CPU already damaged? what are the other methods to solve these problems Best Regards, Attachmentattachment.zip (1066 Downloads) |

Hello, yes it looks that the PLC Card Slot is damage. Do you have some other MMC Cards to test? Christoph |

Hi AutoGen_6548005, MMC format by USB prommer is not recommended. It is possible with only siemens PG. Yes. EIther MMC card or its slot is damaged. |
If you like the comment, rate it (right top) or thank it (left bottom). |

this is not correct! 6ES7792-0AA00-0XA0 with this USB Prommer you cann handle the memorycards in the same way like a siemensPG! |
