easy with Field Bus Interfacing

Commanding, Signalling, Monitoring and Control at Bit Level

A bus connection is valuable even for simple operations, e.g. in production processes. The actuator sensor interface, referred to as AS-i, supplies up to 31 participants with up to 248 binary information packages.

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 easy600 and easy800. 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, timer statii or timing parameters.

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.
