Anybus-IC est une famille de solutions de communication mono processeur. Les interfaces disposent de la fonctionalité complète d'une interface réseau industriel et fournissent une interface d'application réseau indépendante et standardisé pour l'automate hôte. Selon que bus de terrain ou Ethernet industriel est demandé, ces petites interfaces, flexibles et à faible coût sont parfaites pour les besoins de communication des automates de petites et de moyennes taille. Anybus IC fournit une alternative incontestable à un développement interne long.

Pour des automates intelligents avec leur propre microprocesseur, l'Anybus-IC est connecté via son interface série UART et fournit ainsi des fonctionalités de communication avancées incluant des données cycliques d'E/S, des données de paramètres acycliques et des informations sur le diagnostique / le status réseau.

Anybus-IC application examples
Anybus-IC has been optimized for field devices, where small size and multiple network connectivity are important. Anybus-IC contains all electronic components and software necessary to implement a full featured industrial communication interface. Applications such as valve manifolds, and intelligent sensors / actuators are just some of today’s products that are successfully using Anybus-IC.

Case examples:

Anybus-IC inside a valve manifoldValve manifolds
Within a valve manifold, the Anybus-IC can be used to directly interface the electric, magnetic or hydraulic valve drivers. This is made via the SSC shift register interface of the Anybus-IC. The output data received from the fieldbus/Ethernet interface is used to directly open or close the valves. Input data is used to report the position of the valves back to the master on the fieldbus network (PLC). The valve manifold does not necessarily need an own microprocessor as the Anybus-IC provides direct discrete I/O.

Typically, valve blocks are IP65 rated, so the network interface is realized with M12 connectors. The Anybus-IC supports up to 16 bytes of direct discrete input and 16 byte of direct discrete output data via the SSC interface.



Anybus.IC inside an actuatorActuators
Intelligent actuators typically have their own microprocessor. In these devices, Anybus-IC is connected via its asynchronous serial SCI interface with the main microcontroller of the actuator. Anybus-IC handles all communication and offloads the microprocessor of the actuator completely from all time critical communication tasks.

Through the fieldbus/Ethernet network interface and the SCI interface of the Anybus-IC, the actuator is parameterized during start-up. During regular operation, the set point for the actuator is transferred as output data via the fieldbus/Ethernet and the Anybus-IC. While the actual position of the actuator is transmitted as input data via the Anybus-IC and the fieldbus/Ethernet network to the master on the fieldbus/Ethernet network (PLC). Via the SCI interface, the Anybus-IC supports up to 128 bytes input and 128 bytes output data.


Hardware Application Interface
A flexible application interface enables the Anybus-IC to operate either stand-alone or controlled by the host microcontroller. A range of communication channels allows fieldbus/Ethernet data exchange as well as internal discrete I/O. In addition, data can be mapped between the various channels in a flexible manner without any intervention by the host system.

The Anybus-IC is very small and fits into a standard DIL-32 chip socket to connect to the host automation device. It requires a single 5V power supply, and consumes very little power. It also provides a full galvanic isolated network interface.

Flexible data exchange interfaces
Apart from the fieldbus interface, the Anybus-IC features two additional data exchange interfaces (SCI and SSC). These interfaces operate completely independent of each other and can be used simultaneously.

Serial Communication Interface (SCI)
Intelligent devices normally have their own micro controller. The serial 2-wire TTL interface (SCI) is used to connect the Anybus-IC to the micro controller of an intelligent automation device.

This provides access to internal parameters of the module as well as I/O data exchange through the built in Modbus RTU protocol. The communication between the Anybus-IC and the micro controller of the automation device is based on the proven Modbus-RTU protocol. Via the SCI interface, the Anybus-IC supports up to 128 bytes input and 128 bytes output data.

Synchronous Serial Channel (SSC)
The SSC channel is intended to be used with an external shift register loop to form discrete inputs and outputs. It supports up to 17 registers (136 bits) in each direction, out of which 16 (128 bits) can be used for data exchange.

As illustrated below, the first input and output registers in the shift register loop are by default reserved for fieldbus specific functions. It is possible to disable this functionality and use those registers for data exchange instead. The maximum total amount of data is however still limited to 16 registers (128 bits) in each direction.
The functionality of the SSC interface also provides an interface for status, diagnostic and status LED indicators and network address switches.

Monitor (MIF) interface
The serial TTL-level MIF-interface provides an easy way to monitor data and access parameters of the Anybus-IC through a terminal based user interface. The use of this interface is optional

Network interface
The signaling of the network interface is network dependant. For all fieldbus versions, just the fieldbus connector needs to be added. For Ethernet versions the physical isolation transformer (PHY) and the Ethernet connector must be added. Alternatively, fast- jack Ethernet connectors can be used.

SCI Software Interface
The Anybus-IC SCI (serial communication interface) is designed to be network protocol independent, making it possible to support several networks using the same application software. The communication between the Anybus-IC and the host microcontroller is using the proven Modbus-RTU protocol.

The host microcontroller functions as the Modbus-RTU master, while the Anybus-IC functions as the slave. The serial transmission is secured by a CRC checksum which can allow for extended distances between the host microcontroller and the Anybus-IC inside the automation device. The Anybus-IC offloads the host microcontroller from all time critical communication tasks of the selected network. The communication between the Anyus-IC and the host microcontroller is fully under the control of the host microcontroller which mainly defines the level of performance. The transmission speed between the host microcontroller and the Anybus-IC can be selected in a range between 4.8 kBit/s to 57.7 kBit/s with auto baud rate detection by the Anybus-IC.

The Modbus commands are used to read/write cyclic I/O data, acyclic parameters and status, control and diagnostic information. Through the Modbus commands data width and data mapping on the fieldbus/Ethernet network is also initialized.

To speed up the integration of Anybus-IC into the host device, HMS provides free of charge, sample code (C source), to show how the communication between the Anybus-IC and the host microcontroller can be implemented. HMS also supplies a full featured evaluation board with many hardware and software integration tools included.

Data Mapping
Anybus-IC features a flexible memory mapping system. Data received on any of the data exchange interfaces can be mapped (i.e connected) to another data exchange interface, thus forwarding this data from one interface to the other.

This way, the module can be used not only for fieldbus connectivity, but also to provide internal I/O inside the application. (i.e by mapping SSC I/O to the SCI serial interface and vice versa)

By mapping fieldbus I/O to the SSC interface, the digital inputs / outputs provided by this interface are instantly available from the fieldbus.

MIF Configuration Interface
The MIF-interface provides an easy way to configure and monitor the Anybus-IC based on an inbuilt configuration interfaces, accessed by a standard PC terminal emulation program, such as Windows™ Hyper Terminal. The use of this interface is optional, but it provides access to the various parameters of the Anybus-IC, as well as functions for data monitoring and configuration.
