4.10 Function Reference
4.10.1 + (Addition)
Channel whose sample values are added to the 2nd parameter
Channel whose sample values are added to the corresponding sample value from
the 1st parameter, or numerical value added to each sample in the 1st parameter
Channel containing the sum of the 1st and 2nd parameters
Description: The basic addition operation is carried out. The algorithm can be represented thus:
y [k] = u [k] + v [k] or y [k] = u [k] + c
where k is a serial index, c a constant numerical value, u and v are parameter channels and y the result
channel.
Notes: If two channels are added, they must share the same sampling rate. If the 2nd parameteris a
numerical value, it must have the same physical unit as the 1st parameter.
Data types:
Integer or Digital (2nd parameteris an
input channel)
2nd parameteris a numerical value
4.10.2 - (Subtraction)
Channel from whose sample values the values in the 2nd parameterare
subtracted
Channel whose sample values are subtracted from the corresponding sample
value in the 1st parameter, or
numerical value subtracted from each sample in the 1st parameter
Channel containing the difference of the 1st and 2nd parameters
Description: The basic addition operation is carried out. The algorithm can be represented thus:
y [k] = u [k] - v [k] or y [k] = u [k] - c
where k is a serial index, c a constant numerical value, u and v are parameter channels and y the result
channel.
Notes: If two channels are added, they must share the same sampling rate. If the 2nd parameteris a
numerical value, it must have the same physical unit as the 1st parameter.
