Each JCOMM BCMS functions independently and can monitor two panelboards and optionally two
subdistribution feeds to remote power distribution equipment.

Each panelboard has a points list, or Modbus register map, where BCMS records data for that panelboard,
including its main feeds. Customers can choose between two types of panelboard points lists, which are
specialized for different power monitoring requirements:
• The Normal list provides warning and alarm customization for each branch circuit.
• The Power-KWH is specialized for power measurement, recording KW, KWH, KVA, KVAR, and power
factor for each branch circuit.
There is a small separate Subdistribution points list for subdistribution feeds, if these are present and
monitored, providing current data and overcurrent alarms on these circuits.

A panelboard points lists contains data on both the branch circuits in the panelboard and main feeds to the
panelboard:
• Options and parameters from setup, such as voltage sources, main feed CT configuration, and warning
and alarm thresholds
• Direct (calibrated) measurements from CTs and voltage sources
– Current measurements for all 42 branch circuits in a panelboard
– Panelboard measurements, such as voltage, frequency, and current on main feeds (If main feeds are
not directly measured with CTs, BCMS computes panelboard current totals from branch circuit
measurements.)
• Data derived or accumulated from direct measurements, such as min-max current, power factor, or KWH
• Warnings and alarms for branch circuits and panelboards
Configuration options and warning and alarm data are held in non-volatile storage on the board.
The points list documents indicate which registers can be read or written.
Points list documents are available as PDFs from Eaton, see paragraph 2.7 Getting Help .

The Normal and Power-KWH points lists have most points in common, but are specialized for specific tasks.
Information unique to a points list is shown with a grey background in the following tables:
• BCMS Measurements ( Table 7 )
• BCMS Alarm and Warning Configuration ( Table 8 )
• BCMS Alarms and Warnings ( Table 9 )
