* Simultaneity error = the maximum time between switching of the single contacts has been
exceeded.
Manual Reset: If selected, enables the reset request after each activation of the device.
Otherwise, enabling of the output follows directly the conditions of the inputs. Reset may be
of two types: Manual and Monitored. Selecting the Manual option, only transition of the signal
from 0 to 1 is checked. If Monitored is selected, double transition from 0 to 1 and return to 0
is checked.
Parameters
⇒
WARNING: if Reset is enabled, the input consecutive to those used by the functional
block must be used. For example: If inputs 1 and 2 are used for the functional block,
input 3 must be used for Reset.
Power-on test: If selected, enables the power-on test of the device. This test requires
activation and de-activation of the device in order to run a complete functional check and
enable the Output terminal. This test is required only at machine start-up (power-on of the
module).
Filter (ms): Permits filtering of signals from the device. This filter can be set to between 3
and 250 ms and eliminates any rebounds on the contacts. The duration of the filter affects
calculation of module total response time.
With contemporaneity: If selected, activates control of simultaneity between switching of
signals from the device.
Contemporaneity (ms): Is active only if the previous parameter is enabled. Determines the
maximum permissible time (msec) between switching of two different signals from the sensor.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: Permits insertion of a descriptive text of the function of the component.
This text will be displayed in the top part of the symbol.
