Parameters
Manual Reset If this option is selected, a reset must be performed manually every time the function block
is activated. Otherwise, the activation of the output directly follows the state of the inputs.
There are two types of reset: “Manual” or “Monitored”. If the “Manual” option is selected, only
the signal transition from “0” to “1” is checked. In the case of the “Monitored” option, the dou-
ble transition from “0” to “1” and back to “0” is checked.

Output Test Enables the selection of clock signals that are to be connected to the sensor. These addi-
tional diagnostics enable the detection of short circuits and cross-circuits between the ca-
bles. To activate these diagnostics, the clock signals must be configured in the “Property”
window of the relevant function block.
StartUp Test When this function is selected, the sensor must be triggered on machine startup. This test
is performed by activating and deactivating the sensor area.
Filter (ms) The filter can be configured with a value between 3 and 250 ms and helps suppress contact
chatter. The length of the filter time affects the calculation of the response time of the safety
function.
Enable Error Out When this parameter is selected, an output (“E
RROR”) is made available which signals that
an error has been detected by the function block.
Item Description A 24-character text description of the function or the name of the component can be entered
here. The text is displayed above the function block.
NOTE:
Inputs at a function block must always be used in ascending order.
Example: if Input 1 is used for the function block, Input 2 must be used for the reset input.
