Signal Level Detector (SLD)
Each Innovation Series product supplies three SLD channels. Each SLD does a level
comparison on two inputs. The Boolean output of the SLD represents the status of
the comparison. The nature of the comparison is configurable.
Function inputs
The following table specifies the input parameters of the Signal Level Detector
(SLD) function.
Parameter Description
SLD1 input 1 select Selects SLD1 input 1 value
SLD1 input 2 select Selects SLD1 input 2 value
SLD2 input 1 select Selects SLD2 input 1 value
SLD2 input 2 select Selects SLD2 input 2 value
SLD3 input 1 select Selects SLD3 input 1 value
SLD3 input 2 select Selects SLD3 input 2 value
Function outputs
The following table specifies the output variables of the Signal Level Detector (SLD)
function.
Variable Description
SLD1 status Status of SLD1 comparison
SLD2 status Status of SLD2 comparison
SLD3 status Status of SLD3 comparison
