Appendix D—Modbus Register Map Table 125. C445 Modbus Register Map, continued Register Name Attribute Description 395 Base Control Module Relay Status BYTE RO Default: 0 Bitfield Base Control Module Relay Status 396 397 398 Base Control Module Dip Switches WORD RO Bitfield Base Control Module Control Bd Amb Temp SINT16 RO Base Control Module Max Bd Amb Temp SINT16 RW NV Bit Description Coil 0 Q1 state: (0) Open not energized / (1) Closed energized 6305 1 Q2 state: (0) Open not energized / (1) Closed energized 6306 2 Q3 State: (0) Open (latching: relay reset) / (1) Closed (latching: relay set) 6307 Base Control Module Dip Switch Settings Bit Description Coil 0 Switch 1 (close to connector) 6321 1 Switch 2 6322 2 Switch 3 6323 3 Switch 4 6324 4 Switch 5 6325 5 Switch 6 6326 6 Switch 7 6327 7 Switch 8 6328 8 Switch 9 6329 9 Switch 10 (USB—close to top) 6330 Base Control Module Option board—ambient temperature measured on the PCB. Units: ∫C Default: –40 Base Control Module Maximum ambient temperature measured on the PCB. This value can be set (typically to –40). Units: ∫C 400 500 Proof Test Status Active Overload Trip FLA (Nominal Current) Scaled UINT8 RO Default: 0 Enum UINT16 RO Default: 101 (RW) Proof Test Status Value Description 0 Proof test is idle (not triggered) 1 Proof test is running 2 Proof test passed 3 Proof test failed Active Overload Trip FLA (Nominal Current) Scaled is a read only parameter indicating the active FLA. If the application has two windings (and two FLA settings), this parameter will indicate the currently active motor winding setting, Scaled by parameter “I Scale Factor.” Range: 1 to 65535 (RW) Units: scaled A 501 Motor Rated Speed RPM active UINT16 RO RPM nameplate rating of the active motor winding. Default: 1750 Range: 300 to 3600 Units: RPM 502 Motor Rated HP Active Scaled UINT32 RO Units: HPx100 hp nameplate rating of the active motor winding. This value is scaled by 0.01. For example if the motor is rated at 123.25 hp then this parameter should contain 12325. Power Xpert C445 Global Motor Management Relay MN042003EN—September 2015 www.eaton.com 247
