Parameterisation
Module parameter: signal extension time DI
Function number
4828 + m * 64 + 27
m = module number 0
Description
The parameter defines the signal extension time for the electrical inputs 0 and 1
of this module. Signal statuses accepted as logical input signals usually remain
valid at least until the specified signal extension time, minimum signal duration,
has expired. Signal changes within the extension time are ignored.

Comment
If a higher-order controller has long cycle times, there is the danger that short
signals cannot be detected by this controller. A signal extension time can be set
in order for signals of this type to be considered in the control sequence

system description.
The signal extension time defined with this parameter applies to the electrical
inputs of this module and can be activated channel by channel with separate
module parameters.

Module parameter: debounce time DI
Function number
4828 + m * 64 + 27
m = module number 0
Description
The parameter determines when an edge change of the electrical inputs is to be
accepted as a logical input signal for this module.

Comment
Input debounce times are set to eliminate interference from signal edge
changes during switching operations, bouncing of the input signal. The setting
applies to the electrical inputs of this module.
