Universal Application

The PROFIBUS PA Diagnostic Monitor allows testing of the bus physics. In addition, it verifies that the communication between the bus devices is stable. This makes it a universal tool for setup and commissioning, documentation, acceptance testing, preventive maintenance, and troubleshooting.

Very Simple to Use

A display and two function buttons provide outstanding ease of use. The bus test starts automatically when the tool is connected to a PROFIBUS PA network. The test results are clearly classified as either OK or BAD. This tool is an ideal choice even for less experienced users.

Fully Automatic Bus Test

After attaching the tool to the PROFIBUS PA network, the Diagnostic Monitor is powered by the fieldbus and automatically starts testing the segment without operator intervention. If the measured data exceeds the tolerance limits, the operator is informed in plain text.
At the segment level, the tool determines the segment voltage as well as average noise and peak noise for three frequency ranges. Short circuits between the individual signal wires and the cable shield are reliably detected.
At the field device level, the Diagnostic Monitor reports all frame retransmissions and all devices added or dropped during bus operation. The current and the lowest signal levels of all devices are also determined.
No PC or notebook is needed for testing the bus. If required, the PROFIBUS PA Diagnostic Monitor stores the test data for later transfer to a PC via USB. The detailed test reports can be imported to Microsoft® Excel or exported as text files.
