NB1 input 1
[633]
Selection of signal for the 1st input of NB1. This signal will be processed
according the selected operation.
-
Signal
NB1 input 2
[634]
Selection of signal for the 2nd input of NB1. This signal will be processed
according the selected operation.

NB1
operation
[635]
Type of operation used for the numerical block.
plus
plus
NB output is calculated as the sum of input signals.
minus
NB output is calculated as the difference of input signals.
multiply
NB output is calculated as the product of input signals.
minimum
NB output is the minimum of input signals.
maximum
NB output is the maximum of input signals.
abs
NB output is the absolute value of the first input signal.
filter
First input signal is filtered by low pass first-order filter, time constant of this filter is given by
the second input value.
multiplexer
NB output is one of the input signals. If the control signal is inactive, value of the first input will
be used. If the control signal is active, value of the second input will be used.
integrator
NB output is the integral value of the first input signal. Second input signal is used as gain
value. NB output is saturated according to Output (NBx_A) and Output (NBx_B) values.
NB1 control
[1279]
This parameter serves for control of numerical block. It serves as a input
selector for multiplexer operation. It serves as an enable input for other
operations, the operation is performed if enabled, otherwise the previous
output sample is used.
Active
Look choises of parameter's Bit1 DS mask [553] (page 55)
NB1 output
[1254]
Selection of output parameter, to be written to by numerical blok,
according to the linear characteristic set by points A, B.

Signal
NB1_A
[1257]
Result of the operation of numerical block at point A.
