Mobile programmable control device which functionally combines within itself the traditional tasks of a programmable logic controller (PLC) and an active RFID transponder (tag), or, as the case may be, which integrates a PLC and an active RFID transponder in hardware and software terms. The application program for the control device, i.e. including PLC and RFID tag, can be produced using a programming environment conforming to IEC 61131. For that purpose the microcontroller of the RFID tag requires a corresponding runtime environment. The application programs in the control device can thus be executed cyclically and in synchronism with the PLC. By virtue of its small and compact design the control device can be physically attached to mobile objects of a technological process for the purpose of the latter's automation, control or tracking/documentation. Mobile objects also represent process objects in the technological process both physically and in information technology terms.
