Abstract

A measuring system for determining a value of a physical or chemical, measured variable of a medium, includes: a base unit; at least one relay unit connected with the base unit and a sensor unit connected with the relay unit. The sensor unit includes a circuit having at least one microcontroller, at least a first memory region, and a second memory region. The upload software is embodied, in interaction with the microcontroller, to perform an updating of the basic software with at least one software module provided from the base unit. The relay unit includes a circuit having at least one microcontroller, and at least a first memory region, in which a basic software of the relay unit is stored. The circuit of the relay unit further includes a second memory region, in which an upload software of the relay unit is stored.
