9.5 BSI Data Structure for Dialog with PC
FLINTEC weighing indicators 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.
BSI is divided into 2 levels which are;
If you will integrate FT-111 into your computer or if you will interface FT-111 with your PLC which do not have
any fieldbus interface, using BSI commands will help you to expand your system with additional FLINTEC scale
without having to change your application programs.

1.
Commands are only in CAPITAL.
2.
CHK (2 ASCII char) can be enabled or disabled from both command and response.
3.
Weight data and limit values are 8-byte with dot and non-significant zeros on the left.
4.
Headers are 16-byte length.
5.
ID identification data are 32-byte length.
6.
APW at piece weighing are 12-byte length.
7.
Address (2 ASCII char) will be located in the structure, if not 00.
Command format:
A general description of the command is the following:
[ADR][COMMAND][CHK][CR][LF]
Response format with weight:
A general description of the response is the following;
