*Rotary switch adressing setting of
0
is identical to that of
8
, similarly
1
is identical to
9
. This means racks with switch settings of
0
and
8
or
1
and
9
cannot be
connected to the same controller for the six meter module racks.
Table 1: Modbus Addressing for Meter Modules
Table 1 illustrates the Modbus Addressing Schemes as a function of rotary switch settings for both the three and six meter module
rack bus plugs.
Once the rotary switch has been set, replace the bus plug covers and properly label the plug’s rack setting and controller on the
cover label. It is now safe to turn the breakers to the
ON position.
