9.2.2.19. Semiconductor output (SOLID STATE DEVICE)
Using the semiconductor output function block the input status is checked. If 24 VDC are present on the inputs, the OUTPUT
output switches to "1" (TRUE), otherwise the OUTPUT output is "0" (FALSE).

Parameter
Manual Reset: If selected, a reset can be requested on every activation of the safety function. Otherwise the activation of
the output follows the input conditions directly.
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 and Input2 are used for the function block, Input3 must be used for the reset input.
StartUp Test: If selected, the test is undertaken on switching on the safety device. This test requires the activation and
deactivation of the device 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): This parameter makes it possible to filter the signals from the safety device. 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.
Simultaneity (ms): Is always selected. Defines the maximum permissible time (in ms) between the switching of the two
different signals received from the device.
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.
