Module parameters: Signal extension time
Function no.
4828 + m * 64 + 1
m = module number (0 ... 47)
Description
Determines the signal extension time for the relevant I−module. Signal states
accepted as logical input signals usually remain valid at least until the specified
signal extension time (minimum signal duration) has expired. Changes of edge
within the extension time are ignored.
Bit
Bits 6, 7
Values
Bit 7 6
0 0
0 1
1 0
1 1
Signal extension time
Description
0.5 ms
15 ms (presetting)
50 ms
100 ms
[Signal extension]
Note
There is a danger that short signals are not recognized" due to long cycle times
of the higher−order controller. In order that such signals are also taken into con
sideration in the control sequence, a signal extension time can be specified
(see section CPX system manual). The signal extension time can be activated
channel−by−channel (see channel−specific module parameters).

Function no.
4828 + m * 64 + 6
m = module number (0 ... 47)
4828 + m * 64 + 7 (additionally for CPX−16DE, channel 8 ... 15)
Description
Determines whether the signal extension for the relevant I−channel is to be ena
bled or blocked.

Note
The signal extension time can be specified separately for each module
(see function no. 4828 + m * 64 +1, bit 6, 7).
