3.1 AS−Interface addresses
Before connecting to the AS−Interface bus: assign an un
used address to each slave.
Please note
Valve terminal type CPV..−GE−ASI−8E8A−Z M8 contains
2 AS−Interface slaves coupled together. The CPV−...
behaves on the AS−Interface bus like two individual
valve terminals each with 4 inputs and 4 outputs
(valve locations).
Assignment of the inputs and outputs (valves):
Automatic addressing with the function Automatic
address assignment" of the master is not possible.
It is not necessary to parametrize the AS−Interface
slaves.
Address assignment
The assignment of the data bits to the inputs and outputs
of both independent slaves is shown in the following dia
gram.
Data bits:
Inputs:
Outputs:
I/O = Bidirectional (B)
The address mapping depends on the configuration of the
master.
