3.2 Assign AS−Interface slave address
Before connecting to the AS−Interface bus: assign an un
used address to each slave.
Please note
Valve terminal type CPA..−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 4 outputs (valve sole
noid coils).
Assignment of the inputs and outputs (valves):
Slave 1: Inputs I0...I3; outputs O0...O3
Slave 2: Inputs I4...I7; outputs O4...O7.
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 the two slaves one after the other via the addres
sing socket. Use the addresser type ASI−PRG−ADR with a
connecting cable (e.g. part no. 3RK1901−3HA01 from
Siemens).
Permitted address range: 1...31 (factory setting 1; 2)
