The Date/Time information in A139-AI47 is encoded as two

8-bit hexadecimal values. To use these values, first convert

the float values read to an integer, then convert to a 16-bit

hexadecimal number, then convert each of the two bytes

of the hexadecimal number to individual integer values.

The first value (Months, Years or Minutes) is in the least

significant byte of the hexadecimal number, and the second

value (Days, Hours or Seconds) is in the most significant byte

the hexadecimal number.

For example:
Last Restart Timestamp:
AI42 Present Value = 6920
AI43 Present Value = 4876
AI44 Present Value = 15145
AI42 – 6920 -> 1B08 (hex)
Day = 1B (hex) -> 27
Month = 08 (hex) -> 8
AI43 – 4876 -> 130C (hex)
Hour = 13 (hex) -> 19 -> 7 PM
Year = 0C (hex) -> 12
AI44 – 15145 -> 3B29 (hex)
Second = 3B (hex) -> 59
Minute = 29 (hex) -> 41

Analog_Value objects: (can be written as well as read)
Sub-Interval Length

Number of Seconds * 5 (4500 =

15 min)

AV1

n/a

Sub-Interval Length. Sets the length of a sub-interval.

Value is the number of seconds * 5, for example, 4500 is 15

minutes. For sync-to-comms, or sync-to-demand-reset-input

(hardware signal), set this to zero.

# of Sub-Intervals per Demand

Interval

1-6 (1= Block Demand)

AV2

n/a

Number of Sub-Intervals per Demand Interval. Sets the

number of sub-intervals that make a single demand interval.

Legal values are 1 to 6. For block demand, set this to 1.

Command: write values to reset: 1=Dmd; 2=kW Accum; 4=Pk

KW; 8=Pk kVAR

AV3

n/a

Command (bit mapped):
bit 0 (mask 1) = begin new demand sub-interval
bit 1 (mask 2) = clear kWh accumulator
bit 2 (mask 4) = reset peak demand
bit 3 (mask 8) = reset peak kVAR
bits 4-15 = write as zeros to avoid activating any additional

commands that may be added in future revisions.

Phase Loss; Latching Register

(bitmap):

bit0=ph-A; bit1=ph-B;

bit2=ph-C; 3-15 nu

AV4

n/a

Phase Loss, Latching Register (bit mapped):
bit 0 = phase A (unpredictable results, phase A)
bit 1 = phase B
bit 2 = phase C
bits 3 to 15 = write as zeros. User clears this latching register.
