Legend

R/W:

R=Read only, R/W=Read/Write

NV:

Value is stored in non-volatile memory

Format

UInt: Unsiged 16-bit integer, read most significant Byte (MSB) first.

SInt: Signed 16-bit integer, read most significant Byte (MSB) first.

ULong: Unsigned 32-bit integer; Upper 16-bits Most Significant Word (MSW), in
lowest numbered register (257/258)=MSW/LSW)

Float: 32-bit floating point; encoded per IEEE Standard 754 single precision; Upper
16-bits Most Significant Word (MSW) in lowest numbered register (257/258)=MSW/
LSW)

Scale Factor/Multiplier

Integer Registers must be multiplied by this value to be read correctly in the given
units. Scale Factors I, V, W, and E are configurable (see registers 138-141).

Defaults are: I = 0.01, V = 0.1, W = 0.01, E = 0.01

Modbus Commands Supported

0X03: Read holding registers
0x04: Read input registers
0x06: Preset single register
0x10: Preset multiple registers
0x11: Report ID

Return string:

byte0: address

byte1: 0x11

byte2: #bytes following w/out crc

byte3: ID byte = 250

bytes4: status = 0xFF

bytes5+: ID string = “H84__ Power Meter”

last 2 bytes: CRC

0x2B: Read Device Identification, BASIC implementation (0x00, 0x01 and 0x02 data),

Conformity Level 1.

Object Values:

0x01: Vendor Name = “Veris Industries”

0x02: Product Code = “H84__”

0x03: Major/Minor Revision = “Vxx.yyy”, where xx.yyy is the OS version

number (reformatted version of the Modbus register #7001, (Firm

ware Version, Operating System). If register #7001 == 12345, then

the 0x03 data would be “V12.345”).

When the Operating System is erased, only registers 7000-7162 are available. Regis-
ter 7001 (Firmware Version, Operating System) will read as 0 in this condition.
