Operation 4- Funktionen_PDP_DI_Konfiguration
The functions of the inputs and outputs are configured in the system
software.
4.1.1.1 Inputs
Inputs 4- Funktionen_PDP_DI_Eingänge
Single and dual-channel sensors can be connected to the inputs, with
or without test pulses.
Input signals must show a “High” (“1” signal) of 15 VDC (+15 ... +30 VDC)
and a “Low” (“0” signal) of 0 VDC (-3 ... +5 VDC).
The input status is signalled to the control system via the bus.
Green LEDs indicate the status of the inputs.
Test pulses can be used to check the inputs for shorts across contacts
and correct functionality.
4.1.1.2 Outputs
Outputs 4- Funktionen_PDP_DI_Ausgänge
The outputs can be used as standard outputs, as test pulse outputs or
as 24 VDC outputs.
The test pulse outputs are suitable for testing the sensor wiring. All safe-
ty-related inputs must operate in accordance with the failsafe principle
(on switching off).
Two test pulses are available on each plug-in connector; these test puls-
es are permanently assigned to the inputs. The assignment of the test
pulses to the inputs cannot be changed in the system software's config-
urator.
If the test pulse outputs are not being used, they can be configured as
standard outputs or 24 VDC outputs in the system software's configu-
rator.
