W
Prefix before an Identification Number in a
network environment. The IDN is a word
ranging 0-65534.
N
Prefix before an Identification Number in a
network environment. The IDN is a single
byte value, ranging 00-255.
P
Prefix before any command
&
Command connector to make a longer
command by combining up to 6
commands
Notes:
1.
CR stands for Carriage Return and LF for Line Feed.
2.
‘d’ stands for the 0~9 digit numbers.
3.
@ stands for the key value, e.g., 30H for the ‘0’ key.
6.3 Protocol Prefix Usage
Prefix P -
The prefix P can be added before any command in the above table to have the returning data
followed with two bytes of CRC check sum, which is the adding sum of the original character string.
Take the DI+(CR) command as an example. Assume that DI+(CR) would 10m3(CR) (LF)
(the string in hexadecimal is 2BH, 31H, 32H, 33H, 34H, 35H, 36H, 37H, 45H, 2BH, 6DH, 33H, 20H, 0DH,
0AH), then PDI (CR) would 10m3!F7 (CR) (LF). ‘!’ acts as the starter of check sum which
is yielded by adding up the string 2BH, 31H, 32H, 33H, 34H, 35H, 36H, 37H, 45H, 2BH, 30H, 6DH, 33H,
20H. Please note that there will be SPACES (20H) before ‘!’.
Prefix W -
The prefix W should be used in the network environment. The usage format is W+ digit string
which stands for the IDH + basic command. The digit string should have a value between 0 and 65534
except 13 (0DH), 10(0AH), 42 (2AH,*), 38 (26H, &). For example, if the IDN=12345 instrument is
addressed and returning the velocity of that instrument is requested, the command will be W12345DV
(CR).
Prefix N -
The prefix N is a single byte IDN network prefix, not recommended in a new design. It is
reserved only for the purpose of the compatibility with the former versions Command Connector &
The & command connector can connect up to 6 basic commands to form a longer command so that it will
make the programming much easier. For example, assume that the measurement of an instrument with
IDN=4321 are going to be returned, and (then) all the following 3 values--- (1) flow rate (2) velocity (3) POS
totalizer---will be returned simultaneously. The combined command would be W4321DQD&DV&DI+(CR),
and the result would be:
+1.12m3/d (CR)
+3.100m/s (CR)
+10m3 (CR)
