AC drives, also known as variable frequency drives (VFDs), can support various communication protocols that enable them to interface with other devices and systems, such as programmable logic controllers (PLCs), human-machine interfaces (HMIs), and supervisory control and data acquisition (SCADA) systems. Some of the commonly used communication protocols supported by AC drives include:
1. Modbus:
Modbus is a widely used serial communication protocol that allows AC drives to communicate with other devices and systems over RS-485 or Ethernet networks.
2. Profibus:
Profibus is a popular fieldbus communication protocol that enables AC drives to communicate with other devices and systems in industrial automation applications.
3. DeviceNet:
DeviceNet is a communication protocol used in factory automation that enables AC drives to communicate with other devices over a network.
4. EtherNet/IP:
EtherNet/IP is an Ethernet-based communication protocol used in industrial automation that allows AC drives to communicate with other devices over an Ethernet network.
5. CANopen:
CANopen is a communication protocol used in industrial automation that allows AC drives to communicate with other devices over a Controller Area Network (CAN) bus.
6. BACnet:
BACnet is a communication protocol used in building automation systems that enables AC drives to communicate with other building automation devices.
7. Profinet:
Profinet is a communication protocol used in industrial automation that enables AC drives to communicate with other devices over an Ethernet network.
The AC Drive Rockwell, users have access to more than 300 different communication protocols, including Ethernet/IP, DeviceNet, ControlNet, PROFIBUS, and many more. These protocols enable the AC Drive Rockwell to communicate with other devices and systems, such as programmable logic controllers (PLCs), human-machine interfaces (HMIs), and supervisory control and data acquisition (SCADA) systems.
These are just a few examples of the many communication protocols that can be supported by AC drives. The specific communication protocol used depends on the application and the devices and systems involved in the control and monitoring of the AC drives.
