Easy FieldBus Interfacing

Commanding, signalling, monitoring and control at bit level

AS-i is the ideal bus interfacing method for mechanical engineering, as the input and output data is processed with particularly short reaction times of only 5 ms. For example, multiple motors can start-up simultaneously in the area of materials handling.

Bus interfacing is particularly easy with the EASY205-ASI communication module. It can be connected centrally via easy-Link to all expandable 'easy' basic units, such as the Easy 600 and Easy 800. The two core AS-i cable is simply wired to the module – and it is ready to use! The data transfer is controlled by an AS-i Master.

Transferring Complex Data

Higher performance field bus systems such as PROFIBUS-DP are used for more complex automation tasks where the large data volumes are transferred, e.g. multiple analog values, setpoint values or timing parameters.

Up to 20 bytes per network station can be transferred per bus cycle. A maximum of 126 stations separated by a maximum of 1200 metres can be used.

The 'easy' control relay offers even more flexibility and performance with the EASY204-DP bus interface: Complete parameter sets from 'easy' can be output or exchanged via this bus connection. If for example, other recipe or parameter values are required in 'easy', these times, clock times, counter values, setpoint or actual values can be controlled via the high performance field bus system from a respective bus master.

Interfacing to the Worldwide Standard Field Bus Systems

The same functions are offered by the EASY221-CO 'easy'-bus coupler for CANopen and EASY222-DN for DeviceNet.

Interfacing for DeviceNet can be found frequently in the USA and Canada.

These networking features significantly underline the application of 'easy' as a product for world markets.
