PROFIBUS Diagnostic Plug

Logo PROFIBUS Diagnostic Plug

Product description

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 directly indicated by integrated status LEDs and can be reported through the potential-free alarm contact to superordinate control systems. Thus it is possible to reduce failures and to avoid unexpected plant shutdowns. Service and maintenance costs can be planned more proactively.

The baud rate is manually set via the integrated rotary switch and supports the complete range from 9.6 Kbit/s to 12 Mbit/s. Automatic decoding of the baud rate is also possible.

An external power supply is not necessary because the PB
Diagnostic Plug is directly powered by the connected PROFI-BUS node. The required power consumption is only about 40 mW, less than the PROFIBUS maximum default value of 50 mW.
The PB Diagnostic Plug analyses the complete data traffic and triggers typical PROFIBUS specific errors and messages, such as:

- Faulty telegrams
- Retransmissions
- Device-specific diagnostic messages

If PROFIBUS errors are detected, the potential-free alarm contact triggers a one second impulse. Arising error messages
can be quantified on a connected, superordinate control
system by counting the generated impulses. It is possible to reset error messages at any time by pressing the integrated button.
