ABB FPBA-01 PROFIBUS DP Adapter Module

PROFIBUS networks PROFIBUS is an open serial communication standard that allows the exchange of data between all automation components.

There are three main types of PROFIBUS:

- PROFIBUS FMS (Fieldbus Message Specification)

- PROFIBUS DP (decentralized periphery)

- PROFIBUS PA (Process Automation)

The physical transmission medium of the bus is a twisted pair cable (RS-485 compliant).

The maximum length of the bus cable is 100 to 1200 meters, depending on the transmission rate.

Without repeaters, up to 32 nodes can be connected to the same PROFIBUS segment.

If repeaters are used, 126 nodes (including repeaters and a host station) can be connected to the network.

In PROFIBUS communication, the host station - usually a programmable logic controller (PLC) - selects the nodes that respond to the host's commands.

The host can also send commands to multiple nodes in the form of broadcasts; in this case, the nodes do not need to send feedback signals to the host.

The PROFIBUS protocol is described in detail in the IEC 61158 standard.

The communication with the drives is defined in the PROFIdrive PROFILE - The PROFIBUS Profile for Adjustable Speed Drives.

FPBA-01 PROFIBUS DP Adapter Module

The FPBA-01 PROFIBUS DP adapter module is an optional device for ABB drives.

The module connects the drive to a PROFIBUS network. In a PROFIBUS network, the drives act as slaves.

The adapter module makes it possible to

- Send control commands to the drive (e.g. start, stop, run allow)

- Provide the drive with a motor speed or torque determination

- Provide the drive's PID controller with the actual process value or the process decision.

- Read status information and actual values from the drive

- Changing drive parameter values

- Reset drive faults.
