Filter (ms)
: This is used to filter the signals coming from the external contacts. The filter can be
configured to between 3 and 250 ms and eliminates any bouncing on the contacts. The length of
the filter affects the calculation of the unit's total response time.
Concurrent enable
: If selected this activates the test to verify concurrent switching of the signals
coming from the external contacts.
Concurrent (ms)
: This is only active if the previous parameter is enabled. It defines the maximum
time (in msecs) between the switching of two different signals from the external contacts.
Object description
: This allows a description of the component's function to be entered. The text is
displayed in the top part of the symbol.
ESPE (optoelectronic safety light curtain / laser scanner)
ESPE function block verifies an optoelectronic safety
light curtain (or laser scanner) inputs state. If the
area protected by the light curtain is occupied, (light
curtain outputs FALSE) the output is 0 (FALSE).
Otherwise, with the area clear and outputs to 1
(TRUE) the output is 1 (TRUE).
Parameters
Enable reset
: If selected this enables the request to
reset each time the area protected by the safety light
curtain is occupied. Otherwise, enabling of the
output directly follows the input conditions.
There are two types of reset: Manual and Monitored. When Manual is selected the system only
verifies the signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to 1
and then back to 0 is verified.
Î
WARNING: If the Enabled Reset is active, a consecutive Input has to be used. Example:
Input 1 and Input 2 are used for the functional block, then Input 3 has to be used for the
Reset Input.
OUT TEST signals cannot be used in case of safety static output ESPE because the control is
carried out from the ESPE.
