Hi all,
Right now I am on Commisioning in Vietnam and I need urgent help with resetting PLC password.
I have got safety PLC S7 300, CPU 315F-2 PN/DP. I have correct password for safety program, but when I want download safety program or HW configuration to PLC I need another which I don’t have.
So, my questions are:
1) PLC password is stored on MMC? Because I tried reset PLC to delivery state and it didn’t help me.
2) Is there any possibility to format card without any special tool? In Siemens manual is written, that I cannot reset MMC in PLC using MRES button unless PLC isn’t requesting it.
3) Anybody tried this program? http://personal.telefonica.terra.es/web/suwe/ I have got Windows 7 and integrated card reader in my laptop. Maybe I can find laptop with windows XP. MMC card is 2MB.
Any other idea? I can completely erase all program in PLC, it doesn’t matter.
Thank all very much.
