Abstract
In an arrangement (1) comprising at least one field device (2), at least one sensor, or signal, registering unit (3,3a,3b,3c) associated or associable therewith and at least one function block (10,10a,10n), at least one mobile computer unit (4) is provided for performing calculations and/or evaluations. The at least one sensor, or signal, registering unit (3,3a,3b,3c) and the at least one mobile computer unit (4) comprise for wireless communication with one another, in each case, at least one system (7,7a,7b,7c,40) for wireless sending and receiving of data and/or signals.
Claims10
Arrangement (1) comprising at least one field device (2), at least one sensor, or signal, registering unit (3,3a,3b,3c) associated or associable therewith and at least one function block (10,10a,10n), characterized in that at least one mobile computer unit (4) is provided for performing calculations and/or evaluations and the at least one sensor, or signal, registering unit (3,3a,3b,3c) and the at least one mobile computer unit (4) comprise for wireless communication with one another, in each case, at least one system (7,7a,7b,7c,40) for wireless sending and receiving of data and/or signals.
Arrangement (1) as claimed in one of the preceding claims, characterized in that the system (7,7a,7b,7c) for the wireless sending and receiving of data and/or signals of the sensor, or signal, registering unit (3,3a,3b,3c) is connectable or connected with at least one function block (10,10a,10n) and/or a sensor part (30) of the sensor, or signal, registering unit (3,3a,3b,3c) for providing wireless access of the mobile computer unit (4) to the function block (10,10a,10n) and/or the sensor part (30).
Arrangement (1) as claimed in one of the preceding claims, characterized in that the mobile computer unit (4) includes at least one display means (42) and/or at least one memory means (43) and/or at least one wireless Internet connection system.
Arrangement (1) as claimed in one of the preceding claims, characterized in that encrypted data, and/or signal, transmission is provided.
Method for checking a measuring chain in a plant, comprising at least one field device (2), at least one sensor, or signal, registering unit (3) associated therewith and at least one control system (5), wherein the control system (5) is connected with the field device (2) and the sensor, or signal, registering unit (3) by at least one conductor (51) for receiving measured values, characterized in that the sensor, or signal, registering unit (3) registers a signal of the field device (2), transmits such to a mobile computer unit (4) wirelessly and the mobile computer unit (4) calculates therefrom a theoretical measured value and compares such with the current measured value of the field device (2) received at the control system (5).
Method for implementing SIL-measures in a plant comprising at least two field devices (2) with at least one respective, associated sensor, or signal, registering unit (3a,3b,3c) and at least two function blocks (10,10n), characterized in that a system (7a,7b,7c) for wireless sending and receiving signals of the function blocks (10,10n) wirelessly transmits to a mobile computer unit (4) and the mobile computer unit (4) calculates an actual value therefrom and compares such with a predeterminable or predetermined, desired value.
