I have reference of PLC & HMI of Allenbradley from Client. We are using RS-Logix5000 (V19.01) & Factorytalk (V6.0)for PLC & HMI respectively. In that reference I can't see PLC tags in Software of FactoryTalk as they were indirectly refered (That i heard from client). Could anybody tell me how to do indirect referencing of PLC tags in Factorytalk (V 6.0) HMI..............Thanks in advance
