Description
Configuration with SOPAS-ET
Object trigger control
In order to start an object-related reading pro-
cess, the interrogator requires an appropriate
external signal (trigger source) for reporting an
object in the reading area. As standard, the start
signal is emitted via an external reading pulse
sensor (e. g. photoelectric reflex switch). As soon
as an object has passed the reading pulse sen-
sor, a time window opens in the interrogator
("reading gate") for the reading process.
Alternatively, a command activates the reading
process via a data interface or the CAN-SENSOR
network. In Automatic Cycle mode, the actual
interrogator generates the reading gate inter-
nally with an adjustable mark-space ratio.
The reading pulse can be ended in a number of
ways: With external triggering by the reading
pulse source or a command, internally by a timer
or an evaluation condition to be met.
