The BCMS Hub does not support data collection and display from the following devices:
•
WaveStar Power Distribution Units (PDUs) (PowerPak, PowerHub, or PowerHub 2 PDUs)
•
BCMS using the Enhanced Subfeeds points list (large PDU feeds)
•
WaveStar Static Transfer Switch
•
Non-Eaton equipment, except for panelboards monitored through a JCOMM

WaveStar Color Monitors and WaveStar Monitors (monochrome) can be included in the downstream device
chain from the BCMS Hub. However, the PowerWave Bus Systems™ 7-inch Local Display, which is also used
with PowerWave 2™ Bus Systems and PowerWave Silver™ Bus Systems, cannot be used on the Hub’s
downstream Modbus chain.

The downstream link from the BCMS Hub to its monitored devices has standard Modbus RTU restrictions:
•
Up to (32) electrical loads or drops along the downstream device chain. Each connection along the Modbus
RTU bus is an electrical load.
•
Up to (246) total Modbus addresses on the downstream device chain. Each points list has a Modbus
address, including Monitors.

Monitors create Modbus segments consisting of the Monitor and its downstream devices. Monitors are
Modbus clients on their own Modbus segments:
•
The BCMS Hub is the client on its downstream segment.
•
A Monitor on a RPP or JCOMM is the client on its Modbus segment, which usually has just the BCMS
devices (panelboards) in the RPP or JCOMM. Because these devices are in a separate Modbus segment,
they are not directly addressable from the BCMS Hub; the Hub retrieves data from these devices by
addressing the Monitor.
If an RPP or JCOMM has a Monitor, the Monitor connection is the electrical load, and the BCMS cards in the
RPP or JCOMM are not electrical loads. However, if there is no Monitor, each BCMS card is an electrical load
because the BCMS cards are directly addressable from the Hub and is part of the Hub’s downstream Modbus
segment.
For Bus Systems, the Accumulator Board in End Feed is Modbus client to its Tap-Off Boxes. (The 7" Local
Busway Display cannot be used with the BCMS Hub.)
