Using embedded Anybus Communication modules in a Drive / Inverter


7 of the 10 largest drives manufacturers worldwide are customers of HMS, using Anybus connectivity solutions to connect their drives to the variety of industrial networks.


In most drive applications, the distributed drives are located on a machine site and connected via a fieldbus or industrial Ethernet network to the central automation system. In addition to cyclic control processes, modern drives support simultaneously acyclic parameter access through the industrial network. In dependency of the performance and cycle time requirements, many different types of industrial networks are used in drive technology. The networks range from simple fieldbusses such as Modbus-RTU to motion control networks such as EtherCAT or Profinet IRT. To maximize interoperability and interchangeability between the drives of different manufacturers, most industrial networks provide specific functional specifications for drives, the so called drive profiles (i.e. Profidrive for Profibus and Profinet).

With the embedded Anybus communication modules, HMS provides ready-to-use connectivity solutions for standard drives with speed or V/f control and drives with distributed technology functions but with limited motion control requirements. The embedded Anybus modules support fast cyclic I/O data exchange (used i.e for motor current or speed control) as well as acyclic access to the drive parameters (i.e. torque or speed limits). Thanks to the well defined Anybus application software interface, the internal software of the drive can access the cyclic control data and acyclic parameter data in a standardized manner, independent of the selected industrial network.

HMS provides three families of embedded communication modules that fulfill the communication requirements of modern drives / inverters:

Anybus-CompactCom (Anybus-CC)
Plug-in communication modules contained in a robust plastic housing with a form factor similar to a compact flash card. Anybus-CC modules feature the latest Anybus technology combining high performance and low prices.

Anybus-S

Credit card sized communication interfaces containing all hardware and software functions needed to build a powerful communication interface for medium and large drives. Read more

Anybus-IC
Very small sized communication interfaces that fit into a standard DIL 32 socket. These tiny modules are tailor-made for small drives with limited requirements on performance and data size. Read more



Drive Profiles
As a compliment to the standard Anybus communication modules, which contain “only” the full communication functionality of the specific network, HMS provides specific drive profile modules, containing specific drive profile functionalities in addition to the underlying communication functions. These drive profile modules comply with the drive profiles of the network standards making it even easier for the drive manufacturers to fully comply with the syntax and meaning to the industry standards in drive technology. HMS provides two families of embedded communication modules with drive profile functionality:

Anybus-S Drive Profiles
Credit card sized communication interfaces containing all communication functions AND the drive profile features needed to build a powerful communication interface for medium and large drives. Read more


Anybus-CC Drive Profiles
Plug-in communication modules contained in a robust plastic housing with a form factor similar to a compact flash card. Anybus-CC modules with integrated drive profile functionality are currently under development. Please contact your local HMS office for details and availability.

Regardless which specific Anybus module in used, device manufacturers benefit from the principal advantages of the Anybus technology with up to 70% less development efforts, fast time-to-market, easier certification and continuous technology maintenance by HMS.
