Simultaneity (ms)
This parameter is only available if the “Double NC” option is selected. In this case, the block
monitors the simultaneous switching of both input channels.
If a signal change does not occur on both input channels within the defined synchronization
time, an enable signal will not be generated at the output. The maximum time interval be-
tween the two input channels can be configured in the range from 10 ms to 7000 ms.
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 can be entered here. The text is
displayed above the function block.
5.1.2.6 ESPE function block (light grid/safety laser scanner)
The “ESPE” function block (for electro-sensitive protective equipment) checks the status of
the “I
N” inputs of a light grid or laser scanner. When the protection zone of the electro-sen-
sitive protective equipment is interrupted, the “O
UT” output is logic “0”. Otherwise, the pro-
tective field is clear and the “O
UT” output is logic “1”.

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.
The ESPE function block cannot be used for safety equipment such as photoelectric bar-
riers. In this case, the “TESTABLE SENSOR” function block should be used.
