Espe (Electro-Sensitive Protective Equipment) - Siemens Sirius 3RK3 System Manual

6.7.3.2

ESPE (electro-sensitive protective equipment)

Description
With the function "ESPE" (electro-sensitive protective equipment) signals from, for example,
light curtains and laser scanners are evaluated.
When something enters the protective field of the ESPE, the function output Q is
deactivated, i.e. set to "0".

Description/parameter value
You can enter a name for the element here.
Consecutive number which is automatically assigned. You can
change the number.
When this parameter is active, the function is processed in the
safety logic.
When this parameter is deactivated, the set substitute value is
made available at the output Q.
"0" or "1" can be assigned to the substitute value when the
element is deactivated.
Substitute value "0" means output Q = 0
substitute value "1" means output Q = 1
Use these parameters to determine the input type of the function.
Single-channel (NC):
•
IN1 is monitored for "1", i.e. the function output Q is
deactivated when there is a "0" signal.
Two-channel (NCNC):
•
IN1 and IN2 are monitored for "1", i.e. the function output Q is
deactivated when there is at least one "0" signal.
Select the input to be processed by the function.
Only available with the parameter - Input > Two-channel type
(NCNC):
IN2 is automatically assigned depending on the selected input IN1.
Select here when the functions further process the signals:
Input delay = "0":
•
The input signals are further processed by the function without
time delay when there is a signal change.
Input delay not "0":
•
This parameter can be used to suppress signal interference.
The signal state that was pending for most of the duration of
the input delay is further processed.
Please note that the delay time specified by you is a multiple of the
program cycle time specified by you in the properties of the central
unit.
For additional information on the program cycle time, refer to the
Response times
chapter.
