TH SCOPE is diagnostics software for PROFIBUS, PROFINET and Industrial Ethernet. The software can simultaneously monitor several fieldbus networks and communications protocols in an application. Access to the network is implemented via the TH LINK here. Use of TH SCOPE does not require any special knowledge of the communications protocols of the monitored systems. The information is prepared in an understandable form and made available to the user. In the case of network faults, appropriate information for fault correction is presented to the user. The user of TH SCOPE can also obtain information about network problems by means of alarm functions. TH SCOPE supports acceptance test measurements with drafting of an acceptance test log. The status of the network can be saved as a reference for later comparisons.
