6.7.2 Cell functions
6.7.2.1 Input cell
Description
The input cell provides signal states for further processing in the safety logic. The signal
states can be read in, for example, from the terminals of the input modules or also through a
bus system.
The signal of an input cell can be used multiple times in the safety logic.
Parameters
Parameter name Description/parameter value
Element number Consecutive number which is automatically assigned. You can
change the number.
Element activated 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.
General
Function output substitute
value
"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
Terminal - Input Select the input to be processed by the function. Parameters
Input delay [ms] 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.
