Jennic Network Visualization (Pan Sheet)


NoteIf using NiagaraAX-3.8, and planning to install Sedona Framework TXS, you must use an “update 1” bundle of TXS-1.2: version 1.2.1xx (for example 1.2.100). Whereas if using AX-3.7/AX-3.7u1, you use an earlier TXS-1.2 bundle: version 1.2.2x (for example 1.2.28.4). And in the case of AX-3.7u1 (3.7.106 or later), after installing the 1.2.28.4 bundle you need to download and install a patched nsedona module, version 1.2.28.1. For more details, see the latest (February 2014 or later) revision of the NiagaraAX Sedona Framework TXS-1.2 Installer Guide.

This document is about the “PAN Info” mechanism in a SedonaJen6lpNetwork in a NiagaraAX station running on a JACE controller that is equipped with a Sedona Jennic option card. This network type is used to model 802.15.4 wireless (Jennic-based) Sedona Framework devices in the station.

Pan Sheet view on the SedonaJen6lpNetwork provides network visualization

As shown in Figure 1, a “Pan Sheet” view on the network provides a graphic visualization of the underlying “JenNet” self-healing tree structure, along with RF signal strength data of devices. This view uses data collected in “PAN info polling” (or “Load Pan Info” actions) of devices on the network. The Pan Sheet is a diagnostic tool for examining the wireless network, and identifying RF signal strength problems.

NoteDuring normal operation with a stable installed system, enabling PAN info polling is not recommended, as it adds to overall network messaging traffic. However, when first installing a network of Jennic-based devices, or if (and when) subsequent communications issues arise, loading PAN info can be a valuable aid.
