MODBUS REGISTERSEATON Power Xpert® Gateway Series 1000 Card User's Guide 164201670 Rev 4 www.eaton.com/powerquality62Data AddressingThe register addresses and sizes listed in Table 3 through Table 9,starting on page 66, specify an address for each entry. If a data typespans multiple registers (such as a FLOAT), lower addressed registersmap to higher-order parts of the value. Within each register, data is inmost significant bit (MSB) first format.NOTE A Modbus register contains two bytes. Therefore, the number of registerscontaining the information can be obtained by dividing the bytes by two. For example, thevendor name in Table 3 on page 66 can be obtained by reading 32 Modbus registers startingat register 1032.NOTE If a register is not supported in a particular device, an exception response isreturned.PDU/RPP/RPM Unit ID NumbersBecause the PDU/RPP/RPM consists of several panels of circuitbreakers, set the Unit ID in the Modbus program to specify a specificPDU/RPP/RPM, a specific panel, or a specific breaker (see Table 2).The PDU/RPP/RPM has a Unit ID of 0, 1, or 255. The same informationcan be obtained from any of these IDs. See “PDU/RPP/RPM Registersand Alarms” on page 65 for more information.The panel Unit IDs range from 2 to 17. These summary data panelregisters contain the total information for all the breakers in a specificpanel. For example, the registers show the sum total current for eachphase distributed by all the breakers. See “Panel Registers and Alarms”on page 68 for more information.The breaker Unit IDs range from 18 to 33. These registers provideindividual breaker data for the specified panel. See “Breaker Data andAlarms” on page 71 for more information on identifying specific breakerregisters.NOTE Selecting panel and breaker Unit IDs that are not available will return an error code.Currently available PDU/RPP/RPM model configurations are limited to eight panels, so onlyeight panel Unit IDs are used. Future models may be configured for up to 16 panels.If there is an optional Powerware Environmental Monitoring Probe(EMP) installed, use Unit ID 254 to obtain EMP data. See “EMP (FC 04)”on page 74 for more information.
