Available in a typical Profibus plug format, the PB Diagnostic Plug from Comsoft can be connected to any Profibus node. The Profibus baud rate is manually adjusted and includes the complete range from 9600 Bit/s to 12000 Kbit/s. An external power supply is not necessary and the static diagnostic tool consumes only about 40 mW, drawn from the Profibus node. The complete running data traffic is continuously monitored for typical communication errors, such as faulty telegrams and retransmissions as well as device-specific diagnostic messages. Arising errors are indicated by integrated status LEDs and can be reported through the potential-free alarm contact to superordinate control systems. Error messages can be reset at any time by pressing the integrated button. The module helps to avoid plant shutdowns and to reduce technical problems as well as allowing maintenance costs to be planned proactively.
