3.3 Address assignment
The assignment of the data bits to the inputs and outputs
of the slave shows the following figure:
Data bits:
Inputs:
Outputs:
I/O = bi directional (B)
The address mapping depends on the configuration of the
master.
3.4 Connections and address assignment of the inputs
For connecting the inputs, the valve terminal supports the
exchangeable connection technology of the CPX system
(fitting the sub−bases see section 3.1).
