BCMS Hub provides a consolidated power monitoring station for viewing the status
of numerous devices, such as branch circuit panel boards or Bus System End Feeds and Tap-Off Boxes that
use Eaton’s Branch Circuit Monitoring System (BCMS). Monitoring data is displayed on a 10.4-in color
touchscreen. Monitoring data can also be displayed remotely on web pages using a TCP/IP link.
Each BCMS Hub has a single downstream Modbus RTU link to its monitored devices with up to (32)
connections or drops and up to (246) total Modbus addresses. The maximum configuration varies depending
on the type of equipment being monitored. See paragraph 2.6 Electrical Loads and Modbus Addresses for
examples.
A BCMS Dual Hub doubles the monitoring capacity within the same size enclosure using a second Monitor.
NOTE Eaton now handles all service and support for products previously manufactured by
Power Distribution, Inc (PDI). See paragraph 2.7 Getting Help for contact information.

Center Infrastructure Management (DCIM) system:
• (1) Modbus RTU link at 19,200 or 9600 bps
• (1) TCP/IP using Ethernet cable, providing
– Web server connection for remotely viewing BCMS Hub web pages, and/or
– Modbus TCIP/IP connection to BMS or DCIM system
