Electrical connection for AS-i
To supply the AS-i circuit, connect the output on the AS-i Power Extender or an
AS-i power supply to the AS-i/Profibus-Gateway. Observe correct polarity of the
terminals AS-i(+) and AS-i(-).
In the following the desired AS-i slaves are connected to the AS-i circuit.
The AS-i slaves have their device address set to 0 by default. This must be
changed to the desired AS-i slave address.
You can set the AS-i slave address using the function "AS-INTERFACE SLAVE
ADDR" function from the submenu "SETUP" on the AS-i/Profibus Gateway. For
more detailed information, refer to chapter 6.
Once the AS-i circuit has been configured and parameterized as desired, apply
this configuration to the AS-i/PROFIBUS Gateway using the function "QUICK
SETUP".
