BSI Data Structure for Dialog with PC and PLC
New generation 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;
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 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;
[ADR][COMMAND][STATUS][SIGN][WEIGHT][CHK][CR][LF]
Response format without weight:
[ADR][COMMAND][STATUS][CHK][CR][LF]
Note:
CHK, CR and LF will not be shown in below data format descriptions in this section.
Status Table:
The status data in the interfacing are listed below;
A
Ack, the command is operated successfully
D
Dynamic, unstable weight
E
Errors except of H, L, O, +, −.
H
High voltage detected
I
The weight is in range
L
Low voltage detected
M
Mean (Average)
N
Nack, the command couldn’t be operated
O
ADC out
S
Stable weight
X
Syntax error ( not recognized the received command )
+
Overload
−
Underload
BSI-BASE
Command sets of basic weighing instruments, e.g. taring, zeroing, setpoint loading.
BSI-PRO
Extension of the command set for professional weighing indicators, e.g. commands
related with identification data application related commands.
