2. General
2.1 Product information
This system manual applies to the following Bihl+Wiedemann GmbH equipment:
2.2 Product description and intended use
The BW3023 is an AS-interface master according to specification 3.0. It is also
backward compatible because previous specifications (2.0 and 2.1) are support-
ed as well.
It enables configuration, control and diagnosis of up to 31 single slaves or 62 A/B
slaves via LabVIEW.
Fast changing data such as I/O data or execution control flags is directly located
in the SPI frame while slower changing data and data which is only needed in
special situations is located in the command interface.
The LEDs located on the module indicate the current module status, configura-
tion errors or peripheral faults and the activity on AS-i. Diagnostics, which go far
beyond the standard diagnostics facilitate the simple detection of the occasionally
occurring configuration errors and further irritations towards the AS-i communica-
tion. So in case of an error the down time of machines can be minimized or you
can initiate preventive maintenance.
The BW3023 is suitable for use in Class I, Div. 2, Groups A, B, C, D, T4 hazard-
ous locations; Class I, Zone 2, AEx nA IIC T4, and Ex nA IIC T4 hazardous loca-
tions; and nonhazardous locations only.
2.3 Conformity statement
The C-Series AS-i Master Module has been developed and manufactured in ac-
cordance with the applicable european standards and directives.
2.4 Certification according to EN ISO 9001:2008
The manufacturer of the product possesses a certified quality assurance system
in accordance with ISO 9001.

7. 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. For addition help, click Help > Bihl-Wiedemann in LabVIEW to open the
user manual.
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 <Connection of
the AS-i Master>.
2. Open the “AS-i RT Basic.lvproj” example.

3. Verify that your cRIO is connected properly by right clicking the target within
your project and going to "Connect"
4. Open the front panel of the "BW3023 AS-i Commissioning.vi"
Assigning an AS-i Address in the Configuration Mode
Assigning a Slave Address
1. Connect a new slave in the AS-i network, the state of this slave is showed in
the “Slave List” indicator.
2. Select the devices old address within the “Old Address” control.
3. Select the new address within the “New Address” control.
4. Click the button “Change Slave Address”.
5. If the indicator “Result Code” is 0, address assignment was successful.

Programming the Address in Case of Configuration Errors
1. Click the button “Store Actual Configuration” to store the current AS-i net-
work configuration for all connected slaves, then repeat step 2 – 5 from
above.
Erasing the Slave Address
1. Remove a slave from the AS-i network
2. The status of this slave in “Slave List” indicator should change to P (Pro-
jected Only)
3. Click the button “Store Actual Configuration” to delete the address from the
module.
Automatic Address Assignment ( shall be processed only if):
1. the Master module execution control mode is the protected mode,
2. the "Auto_Address_Enable” mode is ON
3. the "Auto_Address_Assign" mode is set, and If one and only one configured
slave is not detected.
7.3 Examples of address assignment
7.3.1 Example of automatic address assignment
1. Select an existing Slave (e.g Slave1) within the “Old Address” control.
2. Select Slave0 within the “New Address” control.
3. Click the button “Change Slave Address”. The status List should change
like this.
4. Remove the slave from the AS-i network.
5. Click button “Operation Mode” to change to protected mode
6. Connect this slave back to the AS-i network
7. Address 1 is assigned to this slave automatically.
7.3.2 Example of manual address assignment
1. Connect a slave to the AS-i network.
2. If the slave address is zero, the status list should look like this.

7.4 Abbreviations used within the Status List Control
7.5 Protected Operating Mode
Only those slaves shall be activated which are both members of the list of detect-
ed slaves (LDS) and members of the list of projected slaves (LPS), and whose
configuration data image (CDI) value equals the permanent configuration data
(PCD) value for that specific slave.
1. Follow steps 1-5 of section <Configuration Mode> to bring the AS-i network
to Configuration mode
2. Click the "Operation Mode" control to change to "Protected Mode"
X (O.K.) The configuration data for the detected AS-i slave matches
the stored configuration data.
D (Detected Only) An AS-i slave is detected at this address, but it was not
stored before.
P (Projected Only) An AS-i slave was stored at this address, but it was not
detected.
