Installation instructions
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 coupled together. The valve
terminal behaves on the AS-Interface bus like two
individual valve terminals each with 4 inputs and 4
outputs (valve locations).
– The addresses are saved electronically and can be
modified at least 10 times. After that the valve ter-
minal maintains the addresses last set.
– Automatic addressing with the function "Automatic
address assignment" of the master is not possible.
Example of address assignment (Siemens S7)
IO code 7
