Abstract
A process automation field device having field device electronics with at least one communication interface and a security module with a plurality of functional units for implementing a plurality of predetermined IT security levels of different severity, the security module having a selection element for selecting an IT security level, the functional units necessary for implementing the selected IT security level being activated and/or the unnecessary functional units being deactivated on the basis of the selection.
Claims23
A process automation field device having field device electronics with at least one communication interface and a security module with a plurality of functional units for implementing a plurality of predetermined information technology (IT) security levels of different severity, the security module having a selection element for selecting an IT security level, the functional units necessary for implementing the selected IT security level being activated and/or the unnecessary functional units being deactivated on the basis of the selection, wherein the functional units are implemented as functional blocks in hardware and/or software, and the functional units comprise hardware elements and software elements.
A retrofitting module for a process automation field device having field device electronics with at least one communication interface, the retrofitting module having a security module, the security module having a selection element for selecting an IT security level, the field device electronics and/or the security module having a plurality of functional units for implementing a plurality of predetermined IT security levels of different severity, the security module cooperating with the field device electronics such that functional units necessary for the implementation are activated and/or unnecessary functional units are deactivated.
A method for setting an information technology (IT) security level in a process automation field device having a security module with a plurality of functional units for implementing a plurality of predetermined IT security levels of different severity, the security module having a selection element for selecting an IT security level, comprising the steps:
- selecting a desired IT security level by means of the selection element,
- reading the selection element, and
- activating necessary functional units and/or deactivating unnecessary functional units for implementing the selected IT security level.
