Signal Based Command Process
About the Signal Based Command (SBC) Process
This process uses a user-defined lookup table to generate a channel command
based on the value of a lookup signal. Lookup tables are defined in a tab-,
comma-, or space-delimited text file that lists the command values for specific
lookup-signal values.
Configuration
SBC process settings allow you to define the lookup-table file path, which
lookup table/lookup signal will generate the command for each channel, and the
control mode for each channel.
Note The SBC process does not support compensation.
Test execution During the test, the SBC process reads the lookup signal, locates the
corresponding signal value in the lookup table, and applies the command defined
for that signal value. Command values for lookup-signal values that are between
user-defined data points are linearly interpolated as shown in the graph below.
If the lookup-signal value is outside the values specified in the lookup table, the
command will hold. For example, in the plot below, a lookup-signal value of 145
degrees would result in a command of 15.224 kN.
