Abstract: Technical task and aim The task on which the invention is based is to make it possible to set up data acquisition and transmission units in remote locations with little outlay, in the shortest possible time and at economic costs, to dismantle them as desired and to deploy them in a flexible manner in other locations. In addition, this permits, depending on the requirements, one or more indication locations, that is to say target locations for displaying information, to be easily assignable and equipped with cost-effective mass-produced display devices. Solution of the technical task It involves an acquisition station which is fitted with one or more units for binary values, analog values and/or counting values or a mixture of the different signal sources. Acquired information is incorporated in a graphic display which is transmitted in cycles, which can be parameterised, to one (or more) fax device(s) at the indication location(s) for example by means of standard telecom services. Field of application The method permits a cost-effective and flexible data transmission, data acquisition and data display in all those locations where due to the absence of an infrastructure, of cost-effective equipment at the indication location and/or high requirements in terms of mobility known, well-established systems cannot be set up, are too expensive and/or too inflexible. <IMAGE>
