Figure 109: A pair of L-IP Redundant devices configured for twin router operation.
Be sure to commission both routers and both diagnostic nodes. Once both routers and both
diagnostic nodes were successfully commissioned, the PRIM LED on one of the two L-IP
Redundant devices should be green and should be off on the other one.
Important:
If bus loop monitoring (see 9.2.1) is not used and thus the loop port 2 terminal of the
L-IP Redundant routers is not connected be sure to first commission the router and the
diagnostic node of one L-IP Redundant and switch off bus loop monitoring on this L-IP
Redundant before connecting the second L-IP Redundant!
After the router and the diagnostic node have been configured, use the L-IP Redundant
Plug-In (see Section 9.5) or the web interface (see Section 9.6) to enter a node list for node
monitoring or to change the parameters for bus loop monitoring and twin router monitoring.
9.5 L-IP Redundant Plug-In
9.5.1 Operation modes
The L-IP Redundant Configuration Plug-In can be used in on-line, off-line, and stand-alone
mode. On-line and off-line mode refers to the two operating modes of your configuration
tool.
9.5.1.1
On-line mode
This is the preferred method to use the configuration utility and allows using the full
functionality of the plug-in. The network management tool is attached to the network and all
network changes are directly propagated into the network. This mode must be used to
commission the device, download and upload the node list, download and clear the alarm
log, and get the current device state.
