How to use the I/A Series R2 (Niagara) WorkPlace Pro to commission LON controllers under an existing LNC-100

[Product_Support]

Issue

When using the I/A Series R2 (Niagara) WorkPlace Pro to commission LON controllers under an existing LNC-100, configure the Local LON device to match the Domain Length, Domain ID, and Subnet ID programmed in the LNC.

Product Line

TAC IA Series

Environment

• I/A Series R2 (Niagara) WorkPlace Pro
• I/A Series Network 8000 LNC-100

Cause

When a third-party network management tool is used to define and commission a LON network, the commissioning tool frequently uses specified domain address instead of the default "zero-length" domain address.  When using the I/A Series (Niagara) R2 WorkPlace Pro to learn a previously commissioned network, Workplace Pro will not be able to discover the LON devices until it has been configured to match the domain address of the network.

1. If the LNC-100 is already communicating to existing controllers on the LON trunk, document the Domain0, Subnet0, and Node0 addressing in either the SYS:SIM or SYS:SIM2 blocks. You don't need to change the existing address in order to add new LON controllers.
2. If you will be using Niagara to commission the new LON controllers, set up the LonWorks Service so that the Local LON device is on the same Domain and Subnet as the LNC-100.
   1. Set the Domain length and Domain ID; go to the Properties of the LonWorksService, Netmgmt tab, Engineering tab, domainId, length, domainId.
      For example, if the SYS:SIM block in the LNC-100 has "DOMAIN0=0D, SUBNET0=01,NODE0=120,..."
      then in the UNC, it should be domain length = 1 (byte), and domainId = 0D.
      Apply the changes.
   2. Set the Niagara subnetNodeId properties: subnetId = 01, nodeId = 127.
      The subnet matches SUBNET0 in the SYS:SIM block.
      Leave the Node ID set to 127
      Apply the changes
   3. Recommission the Local Lon Device. (Remember to disconnect the LNC-100 from the trunk before commissioning!)
3. With the new controllers connected to the LON trunk, go to the Lonworks service, Lon Device Manager, and run the “find” command; the new controllers should be added to the list of nodes. You can use the Lonworks Utilities, command = identify, SubCommand = service pin to be sure you have the correct node. Then commission the new nodes.

Note: Should the LNC-100 be accidentally commissioned, refer to Network 8000 LNC-100 cannot communicate to LON devices under it but can be accessed with WorkPlace T....
