Abstract
The present invention relates to a method for operating an automation field device, having an input interface, a memory which stores at least one set of parameters for operating the field device, and having a first communication interface, wherein, if at least one parameter in the set of parameters is changed by a first entity, the following steps are carried out in the following order: —transmitting at least the changed parameter(s) and/or data calculated therefrom to a superordinate unit, —informing a second entity of the change.
Claims20
A method for operating an automation technology field device, with an input interface, a storage unit, in which at least one parameter set for the operation of the field device is stored, and with a first communication interface, wherein
- in case of at least one parameter of the parameter set being modified by a first entity, the following steps are carried out in the following order:
- transmitting at least the modified parameter or the modified parameters and/or data computed therefrom to a higher-level unit,
- informing a second entity about the modification, and
- activating the modified parameter or the modified parameters only if they have been confirmed by the second entity.
A system for operating field devices, with
- at least one automation technology field device, with an input interface, a storage unit, in which at least one parameter set for the operation of the field device is stored, and a first communication interface, and
- a higher-level unit with a second communication interface, wherein
- the field device and the higher-level unit are configured and adapted such that the field device, in case of at least one parameter of the parameter set being modified by a first entity, transmits the modified parameter or the modified parameters or data computed therefrom to the higher-level unit, and then a second entity is informed about the modification and the field device activates the modified parameter or the modified parameters only if they have been confirmed by the second entity.
