OBJECT FUNCTION BLOCKS
OUTPUT OBJECTS
OSSD (safety outputs)
The OSSD semiconductor safety outputs require no
maintenance, Output1 and Output2 supply 24Vdc if the
input is 1 (TRUE), whereas they supply 0Vdc if the input
is 0 (FALSE).
Î
Each pair of OSSD has an entrance on
RESTART_FBK. This input must always be
connected as described in paragraph
RESTART_FBK.
Parameters
Enabled reset
: If selected
this enables the request to reset (is activated) each time the input signal
falls. Otherwise, enabling of the output directly follows the input conditions.
There are two types of reset: Manual and Monitored. When Manual is selected the system only
verifies the signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to 1
and then back to 0 is verified.
STATUS (signal output)
STATUS output (NOT SAFETY OUTPUT) makes it possible
to monitor any point on the diagram by connecting it to the
input. The output returns 24Vdc if the input is 1 (TRUE), or
0Vdc if the input is 0 (FALSE).
WARNING: The STATUS output is NOT a safety output.
