This small handheld device checks for the most frequently found cable connection faults seen with PROFIBUS DP wiring between pairs of 9-pin D-sub PROFIBUS plugs.

The software checks for open lines, short circuits and crossed connections, reporting any such failures on a red background, with sound signal and text details shown on the front panel colour display. Correct connection test results are reported on a green screen, with different sound signal and show the number of activated terminator switches detected on the tested cable.

If more than 2 terminators are detected this is reported as a fault.
Fault details are emphasised by display of associated conductor colour information, showing green, red or black backgrounds for A line, B line or cable screen/shield respectively.

In addition to connection testing, the unit also allows test tone output onto the PROFIBUS A line, to enable clear separation of IN and OUT cables at a remote location before connection to plug or other unit. Correct orientation of cables within all PROFIBUS plugs and devices is important. A tone detector probe is included for identification of these signals: this unit, as shown in following photo, includes separate tone generation module for tracing LAN and telecom wiring. Both modules are powered by button cells which are provided.

The HP-25 tester is powered by a single 9 volt PP3 battery, with re-chargeable versions also suitable.
