  1. Control Logix 5561

    Hello Michael Thank you for the explanation that is very informative and answers my question completely.
  2. Control Logix 5561

    Hello Peter / Micheal  Thank you both for the quick replies. That answers the questions.  
  3. Hello  We have just purchased some equipment with a Control Logix 5561 (1756-L61/B Rev 13.40). The compact flash card is missing from the unit but the seller says the unit was running in his facility prior to shipping. Does the 5561 have internal memory where a program is stored? Is the Compact Flash used only for recipes and persistent data? Thank you
