Hello guys. I want to change my old CPU 315-2DP to the same CPU 315-2DP. My old CPU has MMC and the program is on it. What should i do when i will install the new CPU? Have any procedure download/upload or just put MMC to the new CPU? THANKS ADI ------------------------------------------------------------------------------------------ |

Hi, yes, change only the MMC but you can use "Ram to Rom" to get the actual values. When you perform the "Copy RAM to ROM..." function, the runtime-relevant data blocks are copied from the main memory to the MMC. Here the actual values of the data blocks are overwritten on the MMC so that after an overall reset new initial values (the new actual values) are effective. These new initial values are displayed in SIMATIC STEP 7 in the "Actual value" column.
Here´s a FAQ about "RAM to ROM" https://support.industry.siemens.com/cs/de/en/view/15389520
Regards, Towome

Hello, Insert MMC into the new CPU when power is off or CPU in STOP mode. Kindly find the attached file. AttachmentInserting_replacing a Micro Memory Card.pdf (807 Downloads) |
