Issue
In the Niagara G3 ASD Device Manager, MicroNet 2000 devices can not be discovered.
Product Line
TAC IA Series
Environment
- I/A Series G3 ENC-410 or ENC-520
- MN-ASDI integrator with attached MN-FLO / MN-FLO3T / MN-HPFC devices
Cause
It appears that the ASD Device Manager checks all MN-ASDI integrators, with DIP switch addresses 1-7, for devices in the range of 1-31 under them.
Resolution
When using the ASD Device Manager to discover MicroNet 2000 devices (MN-ASDI integrators on the ASD bus, and the controllers on the U-buses under the integrators), set the Start Address and End Address in the range of 1 -31.
For example, assume there is an MN-ASDI with DIP switch address = 2, and on the U-Bus under the integrator there is an MN-HPFC with DIP switch address = 3. In the Discovery Filter, set the Discover Mn2k flag= true, Start Address = 1, and End Address = 31. The Device Manager will put a MnHPFC_35 object and a MnGen_32 object in the upper pane. The ASD Device Manager assigned an ASD device address = 32 to MN-ASDI, and an ASD device address of 32+3 = 35 to the MN-HPFC.
It appears that the ASD Device Manager checks all MN-ASDI integrators, with DIP switch addresses 1-7, for devices in the range of 1-31 under them, and then assigns an ASD device address in the range of 32 – 224 to the integrators, and in the range of 1-254 to the MN-FLOs and MN-HPFCs.
