Button Assignment
Downloading the current graph from the scanner for saving it to the PC. The saved graph can
later be used on other scanners of the "Smart" series.
Uploading a graph from the PC into the scanner. The uploaded graph replaces the current
graph and starts calculating automatically.
24.3. Smart blocks
24.3.1. Data types
Each smart block operates with a certain type (several types) of data representing
measurement results, logic signals, etc. Byte order (unless otherwise noted) is LITTLE-
ENDIAN. Description of data types is given in the table:
Name Type Description
internal types Internal types are used to transfer information within a graph. As a rule, they are
composite (contain several fields) and in general should not be used to input and output
data from/to external systems (EthernetIP, UDP, etc.).
SDT_SCALAR scalar_t Scalar. It represents a single measurement/signal value. In the current
revision, it corresponds to the "float" data type. In future revisions, this
may change.
SDT_POINT point_t Point. In the current revision, it has the following structure:
{
float x;
float z;
}
SDT_RECT rect_t Rectangle. In the current revision, it has the following structure:
{
point_t topLeft;
float w;
float h;
}
SDT_SEGMENT segment_t Line segment. In the current revision, it has the following structure:
{
point_t p1;
point_t p2;
}
SDT_LINE line_t Line. In the current revision, it has the following structure:
{
float a;
float b;
float c;
}
SDT_CIRCLE circle_t Circle. In the current revision, it has the following structure:
{
point_t center;
float r;
}
common types Common types are used to transmit data to external (in relation to the scanner) devices
and receive data from them. They are used in conjunction with special conversion blocks.
SDT_BOOL bool_t A logical value that has two mutually exclusive states "TRUE" and
"FALSE". It corresponds to the "uint8" type with the following encoding
scheme:
0 - “FALSE”;
other - “TRUE”.
SDT_FLOAT float Single-precision floating-point value (size - 4 bytes).
