PROFIBUS tester - PB Diagnostic Plug
The PB Diagnostic Plug is connected to any PROFIBUS node,which continuously monitors complete running data traffic for typical communication errors. Errors are indicated directly by integrated status LEDs and can be reported through the potential-free alarm contact to superordinate control systems. It is possible to reduce technical problems and avoid unexpected plant shutdowns. The Service and maintenance costs can be planned more proactively. The external power supply is not necessary because PB Diagnostic Plug is directly powered by the connected PROFIBUS node. In this, any status or error is indicated by integrated green and red LEDs. The low power is about 40 mA.
