4.10.20 Constant digital channel
Parameter
Definition
Clock pulse
Data rate of result channel
Digital value
Numerical return value, 1 (TRUE) or 0 (FALSE).
Result channel
Constant digital channel.
Description: Generates a constant digital channel with the specified pulse rate and binary value 1 (TRUE)
or 0 (FALSE).
Data types:
Result channel
Digital
4.10.21 Conversion to Float numerical format (only for acquisition modules)
Parameter
Definition
Input channel
Channel whose values are to be expressed in Float numerical format
Result channel
Values from Input channel expressed in Float numerical format
Description: Conversion of an integer (2 Byte) to a real number (4Byte) giving regard to the scaling factor
and offset. The real number is determined by the algorithm:
y [k] = Factor * u [k] + Offset
where k is a serial index and u an input channel in Integer data format (devoid of scaling, i.e. without
scaling factor or offset) y is the result channel in Real data format. Factor is the input channel's scaling
factor and Offset Input channel's offset.
Data types:
Input channel
Result channel
Integer or Digital
Real
4.10.22 Event counting (only for DI16 modules)
Parameter
Definition
Input channel
Digital input channel in whose signal events are to be counted
Result clock pulse
Clock pulse rate of results channel
Result channel
Channel containing number of events.
Description: Returns number of events occurring at the digital channel within one result clock pulse
period. An event is a transition from 0 to 1 (or nonzero), i.e., a positive edge.
Notes: Only digital input channels are allowed. The input channel's sampling rate may only be 0.1 ms, 0.2
ms, 0.5 ms or 1 ms.
