M251 User/Password Reset

[trowe]

I am trying to commission a project but the installed TM251MESE has already had a user/password set in it during testing which has since been forgotten.

I have read the instructions on factory resetting the cpu using an SD card but unfortunately I do not have access to a SD card or Card Reader as I am in a remote location.

I tried reflashing firmware using controller assistant but this also requires the password.

I am using Machine expert V2.2, but I beleive the intial config was done with V2.1.

Does anyone know any other method for forcing a factory reset to clear the security credentials in an M251 without using an SD Card?

Hello,

I'm using ME V2.3, but it should be the same with ME V2.2.

From the menu, select "Online" and "Reset Origin."
