2 16-bit registers are transmitted MSB first ( big-endian). Serial RTU is supported on NMC model AP9635, and Modbus TCP is supported on NMC models AP9635, AP9630, AP9631 and bits are atomic within a single Modbus Register . User should not look for consistency across multiple registers , only within a single Register reads of reserved or undefined registers will return an error. Block reads that begin with a valid Register will not return an error but will return zeros for undefined are one word in Signednumbers are two's are one character per number0 is least significant Type column.

3 "INT16" = signed 16-bit integer, "UINT16" = unsigned 16-bit integer, "INT32" = signed 32-bit integer, "UINT32"= unsigned 32-bit integer, "ENUM" is a UINT16 valuethatmaps to a defined list of states, "ASCII" = the printable ASCII subset from 0x20 - 0x7E, "BOOLEAN" = a single bit, 0 or "Absolute Starting Register Address" = 0 (the column heading used in this table) is equivalent to " Register 40001" in Modicon terminology, which is address zero when transmitted over the Modbus Register Map also supports the three-phase Smart-UPS VT and MGE Galaxy 3500 UPS :Most UPS models with the prefix SRC are supported by this Modbus Register Map.

4 For SRC models SRC2 KUXI, SRC3 KUXI, and SRC3 KUXIX709, use the Modbus Register Map entitled Modbus Register Map for Smart-UPS Models with prefix SMT, SMX, SURTD, and SRT , available on : Temperature and Humidity sensors attached to the UIO port(s) of the AP9631 and AP9635 NMC models are not supported via more information on the Modbus protocol, Modbus data formats, and Modbus troubleshooting, see Application Note #168 Modbus Installation and Troubleshooting for AP9635 Network Management Card , available on For detailed Modbus configuration settings, see the AP9635 User Guide, and the Modbus Documentation Addendum on the APC website, Register Map - MGE Galaxy 3500, Smart-UPS VT, and Smart-UPSE xcluding UPS models with prefix SMT, SMX, SURTD, and SRT1990-570208/2018 Modicon Standard Register NumberAbsolute Starting Register Address.
