BCMS boards use Modbus RTU protocol downstream from a JCOMM monitor.
Upstream from a JCOMM monitor, there are three protocol choices, which can be used simultaneously:
• Modbus RTU
• Modbus TCP/IP (high-speed protocol using an Ethernet link)
• SNMP (high-speed, event-driven protocol over an Ethernet link)
TCP/IP can also be used to display Color Monitor web pages. These protocols are specified in monitor setup.
See the
WaveStar Color Monitor, Installation and Operation manual (referenced in Bibliography ) for setup
information.

Figure 15. Modbus Addresses Assigned to Points Lists
Each BCMS points list must be assigned a Modbus address ( Figure 15 ):
• Modbus addresses are for points lists: 1 Modbus address = 1 Points List= 1 BCMS device.
• Each panelboard has a separate points list.
