3.1 AS−Interface Addresses
Before connecting to the AS−Interface bus: assign an un
used address to each slave.
Please note
The valve terminal type CPV..−GE−ASI−8E8A−Z contains
2 AS−Interface slaves. The valve terminal behaves on
the AS−Interface bus like two individual valve ter
minals each with 4 inputs and 3 outputs (valve sole
noid coils).
Assignment of the inputs and outputs (valves):
Slave 1: Inputs I0...I3; outputs O0...O2
Slave 2: Inputs I4...I7; outputs O4...O6.
Automatic addressing with the function Automatic
address assignment" of the master is not possible.
It is not necessary to parametrize the AS−Interface
slave.
Address assignment
The assignment of the data bits to the inputs and outputs
of the slave shows the following figure:
Data bits:
Inputs:
Outputs:
E/A = bi directional (B)
The address mapping depends on the configuration of the
master.
