Anybus-IC - Technical Overview

Communication with or without a microcontroller - flexibility provided by the Anybus-IC.

Flexible Data Exchange Interfaces
Apart from the fieldbus interface, the module features two additional data exchange interfaces (SCI and SSC). These interfaces operate fully independently of each other and can be used simultaneously.

Serial Communication Interface (SCI)
Intelligent devices such as incremental encoders, sensors/actuators, operating terminals and motor control units normally have their own micro controller. The serial 2-wire TTL interface (SCI) connects the module to the micro controller of an intelligent device.
This provides access to internal parameters of the module as well as I/O data exchange through the built in Modbus RTU protocol. This provides access to cyclic I/O data and
acyclic parameters of the network. 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)
For non-intelligent devices, like valve terminals and modular I/O devices, Anybus-IC features
a clocked shift register interface (SSC) that provides direct access to cyclic I/O network
data without the need for an additional microprocessor. With additional A/D or D/A
converts, even analog input or output signals can be easily integrated into fieldbus or industrial Ethernet networks.

Data Mapping
The module 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 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.

Monitor Interface (MIF)
In addition to the serial data interface, the module features a second serial 2-wire interface used for configuration and monitoring using a standard PC terminal emulation program.
The use of this interface is optional, but it provides access to the various parameters of the module, as well as functions for data monitoring and configuration. Mechanical Overview
