6.1.3 KS8000 protocol
6.1.3.1 Protocol Description
Transfer protocol
A simple transfer protocol is used for data communication with the Bus Coupler/Fieldbus Box. Process data
exchange with the BK8x00/IPxxxx-B8x0 invariably involves the complete process image, i.e. a request by
the master leads to the Bus Coupler/Fieldbus Box receiving the complete set of output data and the current
process input data being sent to the master in response. Data communication
• between the Bus Coupler and the individual Bus Terminals is via the K-Bus;
• between the Coupler Box and the individual extension modules is via IP-Link.
In the default setting of the Bus Coupler/Fieldbus Box, access to the I/O signals of the terminals/extension
modules is asynchronous (free running mode). The KS2000 configuration software can be used to switch the
mode to synchronous. In synchronous mode, access by the Bus Coupler/Fieldbus Box to the Bus Terminals/
extension modules is synchronous with access by the controller to the Bus Coupler/Fieldbus Box.
