You can add a LON IP-852 router to the SmartServer. You will typically use an IP-852 router if your installation has a LON IP-852 channel. The LON IP-852 standard requires use of an IP-852 Configuration Server to monitor and configure the IP-852 routers and clients.
This section consists of the following:
The SmartServer IP-852 Router can be used in the following two ways:
As a self-installed IP-852 router. This method allows you to create an IP-852 network with two or more SmartServer IoTs without using a network integration tool to add the SmartServers to the network (similar to the i.LON 600 "Self-install router as repeater" feature). This method is useful when a network integration tool does not know how to use routers. In this case, the IP-852 network is separate from the device network.
This method can only be used if you are using the SmartServer IoT for IP-852 routing. That is, this method cannot be used if you want to use the SmartServer for monitoring, logging, alarming, or scheduling of the device datapoints.
A self-installed IP-852 router is used as a repeater and all traffic on one LonWorks channel (e.g., TP/FT-10) is sent to all other channels. Since many LonWorks channels are half-duplex, you need to make sure that traffic on one channel does not drastically affect bandwidth on all channels.
See the steps described in installation example 1 for more information about setting up self-installed IP-852 routers.
The diagram below shows the SmartServer IoT IP-852 Router network architecture.
There is also a video on the SmartServer IoT Training Videos page that shows you how to enable the LON IP-852 channel routing on your SmartServer IoT, how to manage it in the IP-852 Config Server application, and how to create a VNI RNI attachment point for software that uses the Dialog OpenLDV driver layer.

To use the IP-852 feature, you must:
The procedure that follows provides the necessary steps to enable and define IP-852 devices, beginning with the IzoT CT design and ending with commissioning devices.
Continue setting up the IP-852 feature following the steps in the section below: Enabling IP-852 in the SmartServer IoT Configuration Pages.
Continue setting up the IP-852 feature following the steps in the section below: Defining the IP-852 Channel Devices.
LON Device Management Mode (DMM) is the default SmartServer IoT setting where the SmartServer managed the configuration of all the LON devices provisioned by the SmartServer.
Since IzoT CT is used as the network management tool to manage the network configuration of the LON devices, this setting must be changed to LON Independent Management Mode (IMM), where the SmartServer acts as an independent device in the LON network. The steps below describe how to change this setting from LON DMM to LON IMM using the SmartServer CMS.
Continue setting up the IP-852 feature following the steps in the section below: Commissioning Devices using IzoT CT.
You can use the SmartServer as a direct replacement of the the i.LON 600 without using a network integration tool to provision the SmartServer.
When you enable IP-852 support and attach a U60 network interface to the SmartServer, by default the SmartServer creates and provisions repeaters to connect the IP-852 channel on the LAN or WAN interface to the LON channel attached to the U60. You can use these repeaters to tie two or more LON networks together without using a network integration tool to configure the SmartServers. For example, you can tie LON networks for two or more floors together, or two or more buildings together, an access the connected devices from head-end software.
For direct replacement, follow these steps:
You can use the SmartServer as a direct replacement of the the i.LON 600 using a network integration tool such as IzoT CT to provision the SmartServer. If you are using a single U60 LON interface, you can just commission the IP-852 router and skip commissioning the LON router created for the U60.
For direct replacement, perform the following steps:
Switch the SmartServer to LON Independent Management Mode (IMM) (see Switch off LON Management) using the CMS Devices widget.
The installation will fail if you skip this step.
You can use the SmartServer as a multi-port router by plugging in multiple U60s and U70s. The SmartServer creates an FT to IP-70, TP-1250 to IP-70, or PL to IP-70 router for each U60 FT, U60 TP-1250, or U70 PL-20 you plug into it. The SmartServer also creates an IP-852 to IP-70 router when you enable IP-852 routing on the SmartServer. You must provision all the routers, including the IP-852 to IP-70 router to enable routing between all the channels. To provision the routers in IzoT CT, create an IP-70 backbone channel in the IzoT CT drawing, and the routers, and then commission them. If you are using IzoT CT, switch the SmartServer to LON Independent Management Mode (IMM) (see Switching off LON Management) before provisioning the SmartServer IP-852 and U60 or U70 routers. Following is an example IzoT CT drawing that includes a SmartServer with two U60 FTs, a second SmartServer with a single U60 FT, and two other IP-852 routers.
You can use the SmartServer to monitor and control datapoints on field devices while also acting as an IP-852 router. To enable monitoring and control at the same time as IP-852 routing, add a SmartServer IoT device on the SmartServer IP-70 backbone channel. The SmartServer IoT devices are used by the SmartServer to read and write to external devices. It is important to switch the SmartServer to LON Independent Management Mode (IMM) (see Switching off LON Management) before provisioning the SmartServer IP-852 and U60 routers, and using most of the SmartServer built-in functions.
SmartServer releases prior to 3.1 Update 3 require IP-852 CRC support. SmartServer release 3.1 Update 3 and higher provides the Enforce CRC validation option to support edge servers that do not implement IP-852 cyclical redundancy checks (CRC). By default, the IP-852 CRC validation option is disabled.
To enable IP-852 CRC support, select the Enforce CRC validation checkbox on the LON Configuration page and click Update.
