    FANUC Series 21i-MB “Emergency button” ER97 I / O LINK FAILURE

    Hello!
    Help me please! During the revision of the machine with the FANUC Series 21i-MB stand, one “friend” pulled the battery out of the BAT1 connector of the A02B-0285-B801 unit. Now the machine has stopped working, the message stating that the “Emergency button” is pressed hangs. If you go to PMC ALARM MESSAGE, there is ER97 I / O LINK FAILURE (CH1 04GROUP). I connected to the PLC via the ethernet, in the Ladder 3 program. The program itself is there, but as I understand it, the settings are lost. When trying to save to computer: .lad file is saved but the parameters are not copied - the message L shows: PMC parameter from PMC side (Not EDIT mode). When I try to enable the edit mode, I get the message E:E-6183 This function is protected. When trying to change the keep relay, pops up: H:E-3185 Lie in protest. (Chek PVE.) What to do? Erase all of PMC, , and record with new settings?
