PB Diagnostic Plug
Mini diagnostic tool for permanent monitoring
PROFIBUS Analysis & Test Tools

The PB Diagnostic Plug can be connected to any PROFIBUS node continuously monitoring the complete running data traffic for typical communication errors. Arising errors are indicated directly by integrated status LEDs and can be reported through the potential-free alarm contact to superordinate control systems. Thus it is possible to reduce technical problems and to avoid unexpected plant shutdowns. Service and maintenance costs can be planned more proactively.
Highlights
- An external power supply is not necessary because PB Diagnostic Plug is directly powered by the connected PROFIBUS node. Low power requirement of 40 mA (less than the PROFIBUS minimum default value of 50 mA)
- Analysis of the complete running data traffic and triggering typical PROFIBUS specific errors, such as faulty telegrams, retransmissions, device specific diagnostic messages
- Any status or error is indicated by integrated green and red LEDs
