Sir,
I have installed 1756-L55 Controller in slot-0 and L71 Controller in slot-1 of Control Logix 13 slot chassis. i can read data from L55 in L71 project via produce/consume tags concept but reverse is not happening. i cannot add L71 controller in L55 project's IO configuration. Please advise any firmware upgrade for L55 or firmware downgrade for L71 to have read/write data access between these two Controllers. Thanks.
