The code types for 1D and 2D codes can be selected using the SOPAS-ET Configuration Soft-
ware:
P
ROJECT TREE, ICR880/890, PARAMETER, 1D CODE, register tab SYMBOLOGIES
PROJECT TREE, ICR880/890, PARAMETER, 2D CODE, register tab SYMBOLOGIES
The selected code types can be configured individually. The SOPAS-ET Configuration Soft-
ware has individual register tabs for each type.
3.4.9 Data processing
Tracking operation
During the reading process, a maximum of 10 objects can be simultaneously situated, one
behind the other, in the tracking operation, i. e. the Camera System must be able to unam-
biguously assign the read codes to the objects (Fig. 3-10, Page 30). A reading pulse sensor
controls initiation of the reading process at the start of the reading area as standard (see
Chapter 3.4.2 Object trigger control, Page 26), the end is determined by the object release
point. This also defines the size of the resulting reading area.
A regular pulse is required in order to track objects in the reading area. This is generated by
the external incremental encoder, which delivers a constant pulse at least every 10 mm
(394 mil) of movement in the direction of transport (see Chapter 3.4.6 Increment configu-
ration, Page 28). This allows the Camera System to generate a clear display of the distance
between the reading pulse sensor and the object release point. Any fluctuations during
startup of the conveyor technology or reductions in speed caused by heavy objects are also
detected. For clear separation of consecutive objects, a gap of at least 50 mm (1.97 in) is
required. Reading results for an object are displayed after the rear edge of the object has
passed the object release point. Alternatively, the reading process can be initiated by a com-
mand string via the data interface.
The reading operation mode and object release point can be configured using the SOPAS-
ET Configuration Software:
