Operating the AS-i
The
LabVIEW API
ships with two examples "AS-i RT Basic.lvproj" and
"AS-i FPGA Basic.lvproj" referenced throughout the rest of this Manual. The ex-
amples can be located by the following steps:
1.
Open
LabVIEW
if not already opened.
2.
In LabVIEW click
Help
>
Find Examples
and then search for "AS-i".
3.
Open the
AS-i RT Basic
or
AS-i FPGA Basic
project.
4.

7.1
Master Start-Up
Connect the AS-i module as described in section <Connection samples for
the AS-i power supply> and plug the AS-i module into one slot of your pow-
ered cRIO chassis. All LEDs of the module should be Off.
Then if you run the example “BW-3023 AS-i Commissioning.vi” as described
in section <Configuration Mode>
some LED’s should turn ON, depending on
the state of master.
1.
If the AS-i network is not sufficiently powered.
2.
If the AS-i network is sufficiently powered.
On the VI Frontpanel press the the “Operation Mode” switch and notice your
modules being marked in the address table, then press the “Store Actual
Configuration” button, to turn OFF the Config Error LED.
7.2
Configuration Mode
All slaves, except the slave with zero address, that are members of the list of de-
tected slaves (LDS) shall be automatically detected and activated in the above
mentioned way according to AS-i specification.
Configuration mode is demonstrated in both shipping examples referenced in
section <Examples of address assignment>. The AS-i C-Series module can be
placed into configuration mode by completing the following steps:
1.
Connect the AS-i C-Series module as described in section
2.
Open the “AS-i RT Basic.lvproj” example.
