If the numeric data type is set for integer and the value contains decimal places they
are ignored. In this situation use the decimal offset to ensure that you have an integer
value and then write your code to recognize and handle the decimal offset. Bits 9 to
11 indicate the number of place by which the decimal is to be shifted. Bit 12 indicates
the direction by which the decimal point is shifted, left or right. For example, if the
decimal offset (value of bits 9 to 11) is ‘2’ and the shift (value of bit 12 is ‘0’), then the
decimal point is shifted two places to the right.
Error Codes
The error codes returned in the format area are 8-bit integers found in the lowest 8
bits of the format word. This allows for 256 potential error codes.
Currently the BW500 has two error codes available.
Values Description
0 No error
1 Data not available as percent (available as units)
2-255 Reserved
Date and Time (R41,000 – 41,006)
The date and time can be read or written in registers 41,000 to 41,006 as defined in
the table above.
Example: : If you are located in Toronto, Canada and would like to set the date and
time to February 14, 1999, 1:30 p.m. and 42 seconds, you would write the following:
Register Value
R41,000 1999
R41,001 2
R41,002 14
R41,003 13
R41,004 30
R41,005 42
R41,006 -5
Note:
The time zone register is used only as a reference, and does not affect the
operation of the BW500.
Process Values (R41,010 – R41,048)
Rate, Load, Speed and Total (R41,010 – R41,019)
The associated registers provide the readings of rate, load, and speed. Totalizer 1
and Totalizer 2 in engineering units as displayed in the local BW500 display.
