1. A method for operating a transport system in the form of a long-stator linear motor including a stator on which a plurality of magnetic-field-generating units is arranged and a plurality of transport units which are moved along the stator simultaneously, the method comprising:
in an event of a system error in a part of the transport system, defining an error area on the stator that includes only a part of the stator with a defective part of the transport system, and
transferring the magnetic-field-generating units within the defined error area to a specified error state,
wherein, if a transport unit leaves the defined error area, the method further comprises one of:
expanding the error area so that the transport unit that left the defined error area is within the expanded error area; or
placing a further error area around the transport unit that has left the defined error area.
