  1. Redundancy Error

I'm using L74 controller, Rm2 redenduncy module,  EN2TR and EN2T module (on each chassis) on my control logix project and having 3 remote IO's rack on ring topology... I have use EN2TR for ring topology and EN2T for scada communication. The problem is my controllers are not synchronising on fibre optics... I have to connect both EN2T modules with one an other for controller's synchronisation. They are syncing over ethernet but not over optical... your help is appreciated    Thanks in advance
