SIMATIC CFU PA, in this case with BusAdapter and PROFINET bus cable

SIMATIC CFU PA

The SIMATIC CFU PA basic device has 16 digital interfaces:

• 8 fieldbus connections for PROFIBUS PA, each for 1 PROFIBUS PA field device
• 8 freely configurable digital inputs/outputs (DI/DQ), each for 1 sensor or actuator

PROFIBUS PA field devices are automatically addressed. SIMATIC CFU PA implements system-supported detection and integration of the PA field devices into the process control system using standardized PA profiles (issued by the PROFIBUS&PROFINET user association).

SIMATIC CFU PA also provides standardized detailed diagnostics (NE107) for preventive maintenance of PROFIBUS PA field devices.

In the event of physical faults (for example wire breaks or short circuits), defective connections are automatically disabled. The bus terminator is implemented automatically. Repairs and expansions to the individual connections are possible during runtime.
