ı have a serious problem pm864a. ı add the log file.Please can you help me?
Controller state is Error on backup unit, backup cpu stooped". Adding this status also the modulebus status has "modulebus cluster modem error" and communication backup cpu with tb840 have stopped.Rx1 and Rx2 isnt yellow blinking.
I tried to initialize but didnt work. When trying the lower cpu synchronizing with upper one. The dual led is on then after 5 seconds goes fault let blinking and dual led off.
Can you give a little more background on this?
E.g. what operation was handled on the controller?
Were you downloading, firmware upgrading, switching between controller main and backup cpu, powering up, running for several time or something else?
Since both controllers don't come up together, are you sure both controllers have the same firmware version?
Just turn off one, check the other and then switch the power from one to the other and check the last controller.
So, without the CI867 modules connected, the controllers still won't startup and go in redundant mode?
Did you try a long init on both controllers and download the project again?
Make sure you have a good copy of the project in the controllers first, before you give a long init.
