An apparatus for making an inventory of printed circuit boards (K1-K30) placed in a magazine (M) is provided. A given space on each board is reserved for a programmable memory (EP1) and a first microprocessor (MS1-MS30). The back plane of the magazine is divided into a plurality of part areas (BP1-BP4), where each such area corresponds to a board. A plurality of connection points (S1-S5) in each part area gives information as to the actual position of the board in the magazine. The correct position of the board is stored in the memory (EP1). The first microprocessor compares the actual position with the correct position and sends the result to a second microprocessor (MP) for the entire magazine. The first microprocessor (MS1-MS30) reads out remaining information about the board and sends such information to the second processor (MP). |
