Posted 22 Apr 2020 Hi all, I am new here. I am also not very practical with PlC terminology. I never learnt any programming what so ever, only through, local dealer help and trial and error , have i managed to use the M810 and M820. I Have installed quite a bit of them mostly M810. When i need to access for some kind of modification or diagnosis of the system, I have trouble with the passwords. I was thinking that maybe i have used different passwords or maybe a caps . Always managed to work around the problem as i could find the program on the pc and re load after a flash. However lately i saw that i had a password that i was sure about , i even had taken a photo before i stored it on the M810. However still it did not work. I don't know why this is happening. I have changed the laptop recently, but the local dealer told me it should not do such problems with the password. The concern is even worse because the latest M810 lets you know when giving it a password that it will be rendered useless without the correct password. So if this problem arises i would have to bin the controller. Anyone had this problem before? Thanks and be safe Share this post Link to post Share on other sites
Posted 22 Apr 2020 You can't discuss any type of password circumvention here. If you put the password in then keep guessing at what it could be. That is your only option. Share this post Link to post Share on other sites
