HP-25 PROFIBUS Cable Tester

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 and over daisy chained PROFIBUS cables.

The software checks for and reports open lines, short circuits between cores, shorts between screen and cores, and crossed connections, reporting any such failures on a red background, with sound signal and text details shown on the front panel colour display. On the otherhand, correct connection test results are reported on a green screen, with different sound signal and also show the number of activated terminator switches detected on the tested cable. If 3 or more terminators are detected this is reported as a fault.

All fault reports are emphasized by display of associated conductor colour information, showing green background for A line, red background for the B line and black for the cable screen/shield.

In addition to connection testing, the unit also allows test tone output onto the PROFIBUS A line, potentially helping to confirm clear separation of IN and OUT cables at a remote locations before connection to plug or other unit. Correct orientation of cables within all PROFIBUS plugs and slaves is important to help with subsequent segment commissioning and later fault-finding, as setting of terminator switches at each slave will then allow disconnection from the ongoing cable and later slaves . These tone signals may be heard using commonly available detector probes.
