EATON Power Xpert® Gateway Series 1000 Card User's Guide 164201670 Rev 4 www.eaton.com/powerquality 55Chapter 6 Modbus RegistersThis chapter describes how to address a specific Power Distribution Unit(PDU), Remote Power Panel (RPP) or Power Rack Module (RPM), aspecific panel in a PDU, RPP, or RPM, and a specific breaker in a panelusing Modbus TCP/IP.NOTE To obtain the panel or circuit breaker data, the PDU/RPP/RPM must have the EnergyManagement System (EMS) Level 3 option installed.A PDU/RPP/RPM distributes power through one or more circuit breakerpanels. Each panel consists of several circuit breakers. Each circuitbreaker contains more than 30 parameters, such as voltage, current,power, and alarms. The value of each parameter is stored in acorresponding Modbus data register.Because there are many panels in a PDU/RPP/RPM, it is necessary toidentify a specific breaker and specify the panel containing that breaker.It is likely that Breaker #5 in Panel #1 has different data than Breaker #5in Panel #7.The tables in this chapter list sample names of the PDU/RPP/RPMparameters and their corresponding Modbus registers for: PDU/RPP/RPM summary data Panel summary data Breaker dataThe values of the parameters can be read over an Ethernet network byusing Modbus TCP/IP building monitoring programs or Modbus TCP/IPanalyzer programs.NOTE Some Modbus programs provide an option for zero- or one-based addressing. Selectthe option for zero-based addressing. The Modbus numbering scheme for the PDU/RPP/RPMstarts at 0, so physical coil number 1 corresponds to Modbus register number 0, coil number 2corresponds to Modbus register number 1, and so on.NOTE If your Modbus program requires one-based addressing, add a one to the registeraddresses listed in Table 3 on page 66. For example, one-based addressing for the vendorname would be 1033 (1032 + 1).
