Using embedded Anybus modules in weighing and dosage devices

Increasingly, industrial weighing and dosage devices are equipped with digital communication interface for various fieldbus and industrial Ethernet networks. The devices are used in all types of industrial automation especially in upstream and downstream applications in process automation, batch processes, as well as in packaging systems and for quality inspection and control.

The devices are distributed over the plant and connected via fieldbus or industrial Ethernet systems to the process control system (PCS or PLC). Typically, the devices have slave / adapter functionality in the industrial network. In some applications the devices provide an additional communication link via standard Ethernet-TCP/IP to the ERP and quality system of the production plant.

As modern industrial Ethernet standards such as Modbus TCP, PROFINET IO, EtherNet/IP, BACnet/IP allow simultaneously real-time communication and standard TCP/IP transfers over the same network, one only network interface – that performs both functions at the same time - is needed.

Profiles support interchangeability of devices
Several fieldbus organizations have specified specific application profiles for weighing and dosage systems. The profiles are aimed to increase interoperability and interchangeability between the weighing and dosage devices of different manufacturers. These profiles define dedicated function blocks on the PLC / PCS side and the behavior and parameterization of the devices independently of a manufacturer or control system.

Anybus fulfills the communication requirements
With the embedded Anybus communication modules, HMS provides ready-to-use connectivity solutions for weighing and dosage systems. The embedded Anybus modules support the functionality specified by the weighing and dosage profiles and provide fast cyclic I/O real-time data exchange, acyclic parameter transfers and alarm messaging. In addition, Anybus Ethernet modules permit simultaneously non-real-time standard Ethernet-TCP/IP communication via the same physical Ethernet interface.

Thanks to the well defined Anybus application software interface, the internal software of the devices can access the real-time I/O-data and the Ethernet-TCP/IP socket interface in a standardized manner, independent of which industrial Ethernet real time protocol is used.

The Anybus® CompactCom™ family allows you to integrate fieldbus and industrial Ethernet network capaiblites into your weighing device in various form factors and with different performance capabilities.
