ABB 07 KP 64 Profibus Processor | 12 Mbps, 128B Buffer, 1500V

This communication processor handles data exchange between controllers and field devices. The ABB 07 KP 64 offloads communication tasks from the main CPU. You can connect this module to Profibus DP networks seamlessly. Its intelligent design reduces scan time on the primary processor.

Physical Dimensions and Hardware Layout

The ABB 07 KP 64 measures 12.2 cm in overall width. Its total depth reaches 14.5 cm including the connector hood. This communication processor weighs approximately 0.40 kg. A front panel features five diagnostic LEDs. Two rotary switches set the Profibus station address from 1 to 99.

Protocol Support and Network Capabilities

This module supports Profibus DP slave functionality exclusively. The ABB 07 KP 64 achieves baud rates up to 12 Mbps automatically. Network cycle times reach as low as 2 ms for 32 bytes of data. A built‑in termination resistor simplifies wiring at line ends.

Energy Storage and Data Buffering

Internal capacitors preserve data during short communication interruptions. The ABB 07 KP 64 stores up to 128 bytes of input and output data. This buffer prevents message loss during bus reconfiguration events. Consequently, field devices retain their last valid values temporarily.

Network Integration and Addressing

Set the station address using the two rotary switches. The ABB 07 KP 64 accepts addresses from 1 to 99 only. Position 0 forces the module into a standby mode. The module automatically detects the network baud rate at power‑up. Therefore, manual baud rate configuration becomes unnecessary.

Diagnostic Features and Status Monitoring

Five front panel LEDs simplify network troubleshooting. A green power LED confirms 5V backplane supply presence. A yellow bus LED flashes during active data exchange. A red error LED indicates a configuration mismatch or bus fault. This clear visual feedback accelerates fault diagnosis significantly.
