5.4.2.1.11
Of
If the CAN signal source is selected under the
parameter, the
parameter can be
used to enter the CAN address of a device from the CAN network. This device receives a sui-
table trigger signal and distributes it to the other devices in the CAN network.
5.4.2.1.12
Trigger echo on
If the C
OMMAND
signal source is selected under the
parameter, the command is sent
from the LECTOR
®
620 as a response to the controller if the
parameter is
activated.
As a result, the controller can check transmitted SOPAS commands.
5.4.2.1.13
Reading gate on
Pressing the
button manually opens the reading gate.
So that you can test the current settings, all outputs, output strings and image transmission
function in accordance with the configuration. The reading gate is closed in accordance with
the configuration.
This function is ideally suited to testing operating mode and simulating a machine trig-
ger with a mouse click.
5.4.2.1.14
Reading gate off
Pressing the
button manually closes the reading gate.
This enables you to conclude the reading operation even if the configured condition for au-
tomatically closing the reading gate does not occur.
This function is ideally suited to testing operating mode and simulating a machine trig-
ger with a mouse click.
5.4.2.2
Trigger distribution
The communication from the trigger signal to network users is defined in the
group.
In a network with several reading devices, it is often sufficient to use a photoelectric switch
or connect a reading device to the control. The trigger signal is then distributed to the net-
work users.
function allows trigger signals and the number of photoelectric swit-
ches in use to be significantly reduced. This leads to a significant reduction in system com-
plexity and cost.
