Module parameter: Signal extension time
Modules For modules with digital inputs (see manual for the module)
Function no. 4828 + m * 64 + 1m = module number (0 ... 47)
Description Determines the signal extension time for the relevant 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.

[Signal extension]
Note There is a danger that short signals are not recognised" due to long cycle times
of the higher−order controller. In order that such signals are taken into conside
ration in the control sequence, a signal extension time can be specified (see
section C.2). The signal extension time can be activated channel−by−channel (see
channel−specific
module parameters).

Module parameter: Data format for analogue value of inputs
Modules For modules with analogue inputs (see manual for the module)
Function no. 4828 + m * 64 + 3m = module number (0 ... 47)
Description Determines the data format with which the relevant analogue values are pro
cessed internally.
Bit Bits 0, 1
Values Data format for analogue value of inputs
See manual for the relevant analogue module
[Input format]
Note The choice of data format depends on the fieldbus or fieldbus master used and
simplifies evaluation of the analogue values.
