5.9. BSI Data Structure (for FAD-30 + FAD-30MB only)
Depending on their functionality all new generation Flintec instruments launched on the market support the
standardized command set with BSI data structure. This easy data format gives a reliable and fast interface for
communicating with PLC or PC for process control or transactional applications. You can expand your system
with additional scales from Flintec without having to change your application program base.
General Rules:
1. Commands are only in CAPITAL letters
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 (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]
