Configuring the HGM300 with RDM800 or Laptop PC

The only HGM parameters that are changeable through LonWorks are the alarm thresholds. Configuring the HGM for refrigerant type and length of tubing for each zone (zero length to disable a zone) must be done with the RDM800 remote display or a laptop PC. Refer to the appropriate Bacharach instructions for configuring these items. HGMs are commonly custom-configured at the factory per the customer’s needs, so field configuring these parameters may not be necessary.

If configuring the HGM with an RDM800, the communications adapter’s presence will not affect the standard configuration procedure. If configuring with a laptop PC, temporarily disconnect the HGM300’s RS-485 cable from the adapter until configuration is complete and the laptop is disconnected.

External Interface (XIF) and User Resource Files

Each adapter comes with a disk containing an External Interface (XIF) and User Resource files. The files contain documentation about the network variables contained in the adapter and how they are used. Most network management software will accept XIF files. Echelon LonMaker (and possibly others) will accept User Resource files. A subset of the information in these files is permanently stored in the adapter itself and may be queried over the network once the network management software is aware of the node’s presence.

Identifying the HGM300-LonWorks Adapter on the Network

The adapter can be identified on the network in three ways:

1.If the network management software supports identification by Service Pin, the adapter’s Service pushbutton (directly above the FT-10 twisted pair terminal block) can be pushed when the network management software requests it. This causes a “here I am” message to be broadcast which should be received by the network manager.

2.The adapter’s Neuron chip ID number can be entered manually into the network control PC or handheld tool when requested by the network management software. The Neuron chip ID number is written on the piggyback LonWorks control module in the format XX-XX-XX-XX-XX-XX.

3.If the network management software is capable of finding unconfigured nodes automatically, the Wink command can be sent to the ID of each unconfigured node. Then the nodes can be physically checked to see which node corresponds to which address. When the adapter receives a LonWorks Wink command, it flashes its 1, 2, 5, and 6 Status LEDs in unison for approximately 15 seconds.
