Introduction
The MPR-50’s Monitor observes and reports on the health of Routers 1–5 through
Status LEDs and through the network. The Monitor can be commissioned by a
network management tool and operates independently from the MPR-50’s five
routers.
The Monitor is a L
ONMARK certified application organized as six functional blocks.
In addition to the Node Object, it contains one Channel Monitor functional block
each for Routers 1–5.
For the sake of efficiency, bit arrays, network variable arrays, and configuration
property arrays are used. It is important to understand that the L
ONMARK resource
file and LonMaker tool indices start at zero while, for ease-of-use, the Routers are
numbered one through five on the enclosure, as well as on the LonMaker shapes. The
following table shows the indices to these arrays:
Array
Index
Enclosure Markings Visible Router and Channels Names in the
LonMaker Stencil
0 Router 1 – TP/XF-1250 Router 1 (1250) and Channel 1 (1250)
1 Router 2 – TP/FT-10 Router 2 (FT) and Channel 2 (FT)
2 Router 3 – TP/FT-10 Router 3 (FT) and Channel 3 (FT)
3 Router 4 – TP/FT-10 Router 4 (FT) and Channel 4 (FT)
4 Router 5 – TP/FT-10 Router 5 (FT) and Channel 5 (FT)
Self-Installation
The Monitor self-installs and does not need to be installed by a network management
tool in order to provide status via the front panel LEDs. To obtain status from the
Monitor remotely, it should be installed by a network management tool. The
Monitor intelligently manages its own installation state so that the user does not
need to manage it.
Service Button
Momentarily pressing any of the Service buttons causes the associated Monitor or
router to transmit a service pin message (a router transmits two service pin
messages—one onto the MPR-50’s internal channel and one onto its external
channel). Since the Monitor is attached to the internal channel, a service pin
message from the Monitor will be routed onto a particular external channel only if
the associated router that connects the internal channel to the external channel is
configured to route messages.
