Hi,
I have bought a 1769-L36ERMS from ebay 4 months ago. I bought it just for practice safety features of AB which are not available in my regular AB PLC. Tho I hooked it up the first day just to ensure it runs, I did not have a chance to program it until today. I started running it and noticed there is a safety lock/password on it. I contacted the seller but he did not know. I already searched other older posts here and understood it is against the plctalk policy to help people find passwords.
I just want to know how to reset the memory and no matter if the existing program's gone. I already open the processor module cover and checked inside. There is no removable battery there but one fixed and soldered to the main board. I detached all 3 boards as one for main processor, one for safety and one with blue big capacitors on it from the main board's slots and attached them again. But it is still asking to unlock the PLC for downloading my own program.
So. guys I need your help to find out how I can clean the memory. I can't contact Rockwell as I do not have any account, also they don't probably help me.
