Number Representation (Floating Point)
The Monitor Labs protocol represents all numeric values as
floating point (or integer) ASCII numbers with the most
significant digit transmitted first. The number can include a
decimal point and sign and can be presented in scientific
notation, will an E+xx immediately following the number (with no
space), where xx is the exponent and + is the sign (positive or
negative). Following are examples of legal numeric values:
1 123.456
123456 +1.23456
-1.23456 -1.02
Numbers representing analog or calculated values will be
presented in the default engineering units, regardless of what
units are currently being displayed on the
2010D '
s screen at the
time.
Digital Word Representation
The group commands that accept or return groups of digital data
in the Monitor Labs protocol represent the state of each digital
I/O bit as an ASCII one or zero, where a one indicates and on or
active condition.
In the Model
2010D
, there are two digital I/O groups, the
Control Outputs (that activate solenoid valves, etc.) and the
User I/O. Each group consists of 24 digital I/O bits and is
represented by 24 ASCII 0s or 1s. Within each group of bits,
the lowest numbered I/O point is transmitted first as shown in
the example, below:
Bit#:
1 8 9 16 17 24
Data:
11000101 11101010 00100100
