Hello Mario_D, In which way you want to read data from EEPROM? What do you want to do next? Perhaps might help you? Reading Data from Memory Cart - Entries - Forum ... - Siemens |

Please see [LINK1] for a formal FAQ. This is better help than I give. How the EEPROM works is a little difficult to explain. * The PLC loads only from the EEPROM when the PLC detects that the data has gone missing. For a new PLC the PLC might not need to reload from the EEPROM if power was switched off for 2 or 3 days. * The only way I know of to know if the EEPROM is working - The BEST solution is to use the library and instructions given in [LINK1]. Mario - that is the best I can do for you... good luck. |

William, you are really a big help!!! I usually work with EEPROM on integrated circuit and it is more "simple" to work... But it's hard to make them work with the plc... Now I understand how EEPROM to PLC work and thank you very much!! I tried to use the library but I didn't know that was necessary to cancel setting of Retentive memory! When I will have a week where i don't need to work with plc I will try to test the memory as you suggested. I chose the plc s7-200 because we used for simple applications at school and wanted to learn all its functions. I never use S7-1200 and i didn't want to start from zero, but if necessary I will keep in view. I usually work with microcontrollers because they are cheaper, however, in certain applications, it is better plc. Thank you so much for your help and for the time that you gave me. I will try to use your teaching to best!! We feel the next and good luck!! |
