9.2.2.14. Switch (SWITCH)
Using the SWITCH function block the input status of a pushbutton or switch (NOT A SAFETY SWITCH) is checked. If the
pushbutton is pressed, the OUTPUT output is "1" (TRUE), otherwise the OUTPUT output is "0" (FALSE).

Parameter
Manual Reset: If selected, a reset can be requested on every activation of the device. Otherwise the activation of the output
will correspond directly to the input conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual reset, the system only checks the
signal transition from 0 to 1. With the monitored reset the double transition from 0 to 1 and then back to 0 is checked.

Monitored

Important!
If manual reset is selected, the next input after the inputs used by the function block must be used.
Example: If Input1 is used for the function block, Input2 must be used for the reset input.
Output Test: Using this option you can select which test output signals are to be sent to the switch. Short circuits between
the wires can be detected and rectified by means of this additional check. For this purpose it is necessary to configure the
test output signals (from the test output signals available).
StartUp Test: If selected, the test is undertaken on switching on the switch. This test is undertaken by closing and opening
the switch to carry out one complete function test and to activate the output. This test is only requested on starting the
machine (on switching on the module).
Filter (ms): Makes it possible to filter the signals that are received from the switch. This filter can be set to between 3 and
250 ms and removes any contact bounce. The time set for the filter affects the calculation of the total response time of
the module.
Enable Error Out: If selected, an error detected by the function block is displayed.
Item Description: Here you can enter a functional description for the component. This text is displayed in the upper part of
the symbol.
