4.1.6 Module Function External Input
The module uses no inputs and no outputs and is only used for the parameterization
of the function of the external input at the Laser Measuring Device.
The available options are:
Function ext. input
Determines, whether the switching input is to be used as Preset input or for switching-
off of the laser diode (LD). With connection of the switching input as Preset-input the
laser is adjusted on the predefined position value (Preset HI word and LO word). With
connection the switching input as LD-input the laser diode is switched off for the
extension of the life time. If in the PC-program "OMSConfiguration-Tool" in the basic
parameters the switching-off of the laser diode is carried out automatically, the LD-
switching input does not have a function.
disabled (default)
Function switched off, following parameters without
meaning
Preset-function External switching input is determined as Preset input
LD-switching input
External switching input is used for switching-off of the laser diode.
Alternative: Software switching-off see chapter 4.1.9 page 25.
Preset 1 HI word and LO word
It determine the position value to which the laser is adjusted, when the preset function
is executed. The preset value must be programmed in the range from
0 ... measuring length. Default value is "0" .
active edge
Determines, whether the function of the switching input is activated with an rising or
falling edge at the switching input.
This parameter has no influence at the release of a function over a control bit via the
Profibus. There is always the rising edge valid.
L->H (default) Function release with rising edge
H->L Function release with falling edge
Response time
It determines the response time of the switching edge of the switching input up to the
actual execution. This parameter is used for the interference suppression of the signal
at the switching input.
100 ms (default) Response time = 100 ms
250 ms Response time = 250 ms
500 ms Response time = 500 ms
1000 ms Response time = 1000 ms
