2.8 Connecting bus systems
The easy-Link connection is designed in such a way that bus modules other
than input/output expansions can also be connected. Special bus modules
(gateways) are available for the relevant bus systems.
At present easy700 can communicate via the following bus systems or
networks:
• AS-Interface (Actuator-Sensor Interface)
• Profibus-DP
• CANopen
• DeviceNET
• Ethernet gateway.
The functionality of bus systems varies. The following generally applies:
• As a minimum data exchange, the input data R1 to R16 and output data
S1 to S8 can be exchanged, provided that the bus system supports this.
• If the bus system or bus gateway is capable of this, function block, date,
time parameters can be read and written via the bus. The states of
inputs, outputs, markers can be read.
￫
easy-Link allows the connection of one device (expansion unit or
bus module).
￫
The range and the functions of the bus gateways are being
continually further developed.
Our latest product range or Internet online catalogue contains
the valid and available bus modules.
