1 Create a control program in Snap
LonWorks Integration Guide CARRIER CORPORATION 2020
i-Vu Link and Open Link All rights reserved
4
When you create a control program for each type of LonWorks device, use the following Network I/O microblocks:
One ANI, ANI2, BNI, or BNI2 to read each element of interest in an nvo SNVT
One ANO, ANO2, BNO, or BNO2 to write to each element of interest in an nvi SNVT
TIP The SNVT definitions in Appendix A (page 14) may help you determine whether you need an analog or binary
microblock.
To format a LonWorks address
All Lonworks addresses should be assigned to "lonworks://" only when setting up address strings in
EquipmentBuilder. The LonWorks Integration Tool is used to define these addresses.
An example of a LonWorks address:
lonworks://0/1/2/3ff5/108/0/0/0
Details:
lonworks://domain_index/subnet/node/nv_Number(Selector in HEX)/SNVT Type/NV Element/ Property/group
group is always 0 (zero)
Property = 1 for ANI/BNI
Property = 0 for ANO/BNO
NOTE Carrier does not support a Domain Length of 0 (zero)

CAUTION!
You will damage the SLTA-10 if it does not have its own isolated power supply. Do not share power with the i-Vu
Link/Open Link.
1 Turn off the i-Vu Link/Open Links power.
2 Remove power from the SLTA-10.
3 Set SLTA-10 DIP switches 18 as shown below. Switches 68 set the baud rate to 57600 for
communications between the control module and the SLTA-10 .
4 Wire the i-Vu Link/Open Link's Port S2 to the SLTA-10's EIA-232 port using one of the following methods:
If you have an EIA-232/RS-232 straight-through cable with connectors and an S2-DB9 Adapter:
Connect the adapter to the control module's port. Then connect one end of the cable to the adapter and
the other end to the SLTA-10's EIA-232 port.
If you have an 18-22 AWG, 4-conductor cable and a DB9 male adapter:
Wire one end of the cable to the control module's port and the other end to the adapter. See table below.
Then connect the adapter to the SLTA-10's EIA-232 port.

Field Notes
Node ID In this field, you are giving the SLTA/Router or Link an ID number on
the LonWorks network. Type any value in the range 1127, but it
cannot be the same as the Node ID of any LonLonWorks device on
the LonLonWorks network. 99 is typically a good number to use.
Authentication Key
Do not change these values for most applications.
The i-Vu or Field Assistant application uses this authentication
code if the third-party device requests authentication.
10 Click the Apply to refresh the page. Verify the following values in the SLTA Node Status section:
SLTA Comm Established: Yes
(SLTA-10 and Carrier controller are communicating.)
SLTA Node Online: Yes
(SLTA-10 and LonWorks network are communicating.)
SLTA Node Configured: Yes
(SLTA-10 has been commissioned.)
Address Domain: (As displayed in the SLTA Domain Table)
11 On the navigation tree, select Protocols.
12 In the Protocol Status table, verify that the LonWorks protocol shows Running on Port S2.
If the status shows Not running or the wrong port, verify port selection and DIP switch settings for that port on the
