MX08 Multichannel Weighing System, Technical Manual, Rev. 2.5 Page 29 of 144
4.11. BSI Data Structure
All new generation BAYKON instruments launched on the market support the standardized
command set BSI data form, depending on the functionality of the instrument. This easy
data format gives the reliable and speedy interface advantages with communicating PLC
or PC for process control or transactional applications. You can expand your system with
additional scales from BAYKON without having to change your application program base.
General Rules:
1.
Commands are only in CAPITAL
2.
CHK (2 ASCII char) can be enabled or disabled from both command and response.
3.
Weight data is 8-byte with dot and non-significant zeros on the left.
4.
Address data (2 ASCII char) will be located in the structure. 1
st
char is address byte
of N-Bus master instrument and 2
nd
char is address byte of N-Bus slave instrument.
5.
N-Bus master instrument‘s address byte is default “1” for RS-232C and Ethernet
interfaces.
Command format: A general description of the command is the following:
[ADR][COMMAND][CHK][CR][LF]
Response format with weight / force or count data
A general description of the response is the following:
[ADR][COMMAND][STATUS][SIGN][WEIGHT/FORCE/COUNT][CHK][CR][LF]
Response format without weight / force or count data
[ADR][COMMAND][STATUS][CHK][CR][LF]
