Device and methods for identifying modules in a graphics machine

A graphics machine comprising:

• a controller;
• a first device connected to the controller, the first device including a type identifier that provides at least one measurable signal, the first device being categorizable as one of at least a first type and a second type;
• and
• a memory accessible by the controller, the memory storing information regarding the first type and the second type, the controller determining whether the first device is of the first type or the second type based on the at least one measurable signal and the information stored in the memory.

A method for operating a conveyor line for collecting printed products comprising:

• operating a plurality of devices at stations along a conveyor to create a first printed product configuration, the plurality of devices including at least a first feeder feeding a first printed product to the conveyor and a second feeder feeding a second printed product collected with the first printed product;
• exchanging one of the plurality of devices with a second device of another type;
• detecting at a controller a type of the second device;
• and
• operating the conveyor line as a function of the detecting to create a second product configuration different from the first printed product configuration.
