Siemens SEM3 - Meter Addressing and Rack Setup; Meter Racks and Address Ranges; Meter Module Internal Address Mapping

5
The 3 and 6 module racks can be used as an extension to any of the other racks or pairs of racks. Settings must be such that no
address is used more than once. Duplication of addresses will return an error on setup.
Meter Module Internal Addresses – Dip and rotary switches on the racks are used to assign the unique addresses for the
meter module. Table 1 indicates rack addresses for Left setting on 9, 15 and 21 module racks and setting 0‐7 on 3 meter module
rack, 0‐3 on 6 meter module rack. Table 2 indicates addresses for right setting on 9, 15, and 21 module racks and 8‐F on 3 meter
module rack, 4‐7 on 6 meter module rack. Right chart indicates addresses for right setting on 9, 15, and 21 module racks and 8‐F on
3 module rack.
Meter Racks – The meter module racks have the addresses for the module to controller communications hard coded into them. The 9,
15 and 21 module racks have a two position dip switch for setting one of two address ranges for each. The three and six module rack
has a rotary switch to allow it to be configured for multiple address ranges. The chart below shows the ranges available for each rack.
