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.
