In a medicament dispensing system including a plurality of medicament dispensing cells, a manipulator operable for moving to a selected cell for receiving medicament therefrom, and a controller for controlling the operation of the manipulator, a method of replenishing the cells with respective medicaments comprising the steps of:

  • (a) determining a selected cell for replenishment of medicament assigned thereto,each of the cells having machine-readable cell indicia thereon representative of the medicaments assigned thereto;

    (b) selecting a container containing a medicament and having container indicia thereon representative of a medicament contained therein,the system including an indicia reader coupled with the controller, said indicia reader including means for reading said cell and container indicia, for producing indicia signals representative thereof and for delivering said indicia signals to said controller;

    (c) using said indicia reader to read said cell and container indicia and to produce respective cell indicia signals and container indicia signals representative thereof; and

    (d) in the controller, receiving said cell indicia signals and container indicia signals and determining whether there is a match between medicaments represented thereby;

    (e) if there is a lack of a match between medicaments represented by said cell indicia signals and container indicia signals, providing a mismatch output detectable by an attendant indicating that replenishment of medicament from said container is disallowed and, if there is a match between medicaments represented by said cell indicia signals and container indicia signals, producing a match output detectable by an attendant indicating that replenishment of said selected cell by medicament from said container is allowed.
