Hi Mates, We have an 1756 L75 Redundant system (L75:RM:EN2TR:N2) in our plant and it was working well, recently it was powered up after a short vacation and I tried downloading a new program to the primary (primary already had one running) and i was notified with error in the RsLogix 5000 that Program cant be downloaded with secondary disqualified.
I noticed secondary RM shows "Disq" and its controller showed "No Project" and the primary RM showed "PRIM" and controller is running.After re-booting the controllers several times I got the secondary to SYNC and successfully downloaded the new project.
My question is> Is it not possible to download a new project to the primary controller when the secondary is Disqualified ? Any specific reasons!
