Abstract
Apparatus for testing data communications on two wire combined power and data network systems for automation, comprising a control means and connection means adapted to connect said apparatus to a subject network segment, in which said control means comprises data signal output means adapted to impart a test data signal to said subject segment via said connection means, and a data signal disruption means adapted to vary one or more physical layer attributes of said test data signal which affect its functional quality and/or to vary one or more physical layer attributes of said subject segment which are capable of affecting the functional quality of data signals carried thereon.
Claims12
An apparatus for testing data communications on two wire combined power and data network systems for automation, comprising a control device and a connector adapted to connect said apparatus to a subject network segment, in which said control device comprises data signal output adapted to impart a test data signal to said subject segment via said connector, and a data signal disrupter adapted to vary one or more physical layer attributes of said test data signal which affect its functional quality and/or to vary one or more physical layer attributes of said subject segment which are capable of affecting the functional quality of data signals carried thereon, and in which said apparatus is for testing data communications on a subject network segment operating under a two wire combined power and data network fieldbus-type protocol, in which said connector is adapted to connect said apparatus to said subject segment operating under the two wire combined power and data network fieldbus-type protocol, and in which said data signal output is adapted to impart a test data signal to said subject segment via said connector which test data signal is in accordance with the two wire combined power and data network fieldbus-type protocol.
An apparatus for testing data communications on two wire combined power and data network systems for automation, comprising a control means and connection means adapted to connect said apparatus to a subject network segment, in which said control means comprises data signal output means adapted to impart a test data signal to said subject segment via said connection means, and a data signal disruption means adapted to vary one or more physical layer attributes of said test data signal which affect its functional quality and/or to vary one or more physical layer attributes of said subject segment which are capable of affecting the functional quality of data signals carried thereon;
- and
- wherein said apparatus is for testing data communications on IEC61158-2 Fieldbus segments, in which said connection means is adapted to connect said apparatus to a subject IEC61158-2 Fieldbus segment, and in which said data signal output means is adapted to impart a test IEC61158-2 Fieldbus data signal to said subject segment via said connection means.
An apparatus for testing data communications on two wire combined power and data network systems for automation, comprising a control means and connection means adapted to connect said apparatus to a subject network segment, in which said control means comprises data signal output means adapted to impart a test data signal to said subject segment via said connection means, and a data signal disruption means adapted to vary one or more physical layer attributes of said test data signal which affect its functional quality and/or to vary one or more physical layer attributes of said subject segment which are capable of affecting the functional quality of data signals carried thereon;
- and
- wherein said apparatus is for testing data communications on a subject network segment operating under a combined power and data network fieldbus-type protocol, in which said connection means is adapted to connect said apparatus to said subject segment operating under a combined power and data network fieldbus-type protocol, and in which said data signal output is adapted to impart a test data signal to said subject segment via said connection means which test data signal is in accordance with the combined power and data network fieldbus-type protocol.
