Abstract
A field communication test device is provided on a field bus, to which a plurality of field equipments are connected, and also connected to a debug network to apply a communication test to respective field equipments. The field communication test device transmits/receives cooperation data, which is used to apply the communication test in cooperation with each other, to and from other field communication test device provided on the field bus, via the debug network, and transmits test data for the communication test to the respective field equipments via the field bus base on the cooperation data.
Claims8
A field communication test device for testing a plurality of field equipment configured for disposition within a field communication system comprising:
- a field bus communication portion coupled to a field bus, to which a plurality of field equipment are connected,
- a debug network communication portion connected to a debug network, which is different from the field bus, to apply a communication test to respective field equipment, and
- at least one transmission/reception unit whereby the field communication test device (1) transmits/receives cooperation data, which is used to apply the communication test in cooperation with other field communication test devices provided on the field bus to/from said other field communication test devices, via said debug network communication portion and the debug network, and (2) transmits test data for the communication test to the respective field equipment via said field bus communication portion and the field bus based on the cooperation data.
A field communication test device for testing a plurality of field equipment comprising:
- a first communication portion for connecting to a debug network to apply a communication test to respective field equipment;
- a second communication portion for coupling to a field bus, to which a plurality of field equipment are connected;
- wherein, said first communication portion holds data communication with the other field communication test devices via the debug network, and said second communication portion holds data communication for the communication test with respective field-equipment via the field bus,
- at least one transmission/reception unit whereby the field communication test device (1) transmits/receives cooperation data, which is used to apply the communication test in cooperation with other field communication test devices provided on the field bus to/from said other field communication test devices, via the first communication portion and the debug network, and (2) transmits test data for the communication test to the respective field equipment via the second communication portion and the field bus based on the cooperation data,
- a storing portion which stores a test case used to apply at least any one of a normal communication test in which the field communication test device operates as the field equipment that operate normally and transmits the test data for the communication test, a particular sequence/timing test in which the test data for the communication test is transmitted in a sequence or at a predetermined timing in communications between the plurality of field equipment, and an abnormal communication test in which the field communication test device operates as the field equipment that operate not to meet the specification specified in advance by the protocol of each field equipment and transmits the test data for the communication test, and
- an operation controlling portion which transmits/receives the cooperation data by controlling the first communication portion in accordance with each test case, and transmits data for the communication test to respective field equipment as a subject of test by controlling the second communication portion based on the cooperation data.
