Term/abbreviation Meaning
Exposure time The duration for which the CMOS sensor is subjected to light during
image capturing. The longer the exposure time, the more light will
penetrate. The exposure time is chosen on the basis of e.g. speed of
travel, amount of light available, and the light sensitivity of the
sensor (
è
Sensor amplification). In the case of moving objects, long
exposure times result in blurred images.
Falling edge Transition from logic 1 to logic 0 (falling).
Feature(s) Defined values (e.g. length) that are determined by the check pro­
gram and used for analysis.
Fieldbus nodes Provide the connection to specific fieldbuses. Transmit control sig­
nals to the connected modules and monitor their ability to function.
Focal depth
è
Depth of focus
Focal length Large focal lengths create a large image, while small focal lengths
create a wide-angle image. Lenses with variable focal lengths are
known as zoom lenses. Lenses with greater focal lengths usually
have a smaller depth of focus and a lower luminous intensity.
I Digital input.
I module Input module.
I/O modules Collective term for the modules which provide digital inputs and
outputs (e.g. CPX I/O modules, CP input modules and CP output
modules).
I/Os Digital inputs and outputs.
Logic 0 Input or output supplies 0 V.
Logic 1 Input or output supplies 24 V.
Modbus TCP Communication standard via TCP/IP in automation technology.
O Digital output.
O module Output module.
PLC/IPC Programmable logic controller/industrial PC
Rising edge Transition from logic 0 to logic 1 (rising).
SBO-DeviceManager Software package for adjusting the network properties and firm­
ware.
