The USC701 has four look up tables to linearize measurements taken typically from industrial sensors. An example of this is the thermocouple.
The USC configuration wizard creates hidden equations to directly linearize the sensor input.
However situations will arise where a signal from an number of inputs are added, multiplied etc. and then linerized. This can be done by inserting the table within the general equation.
As previously mentioned there are four lookup tables within the USC701. The program wizard will assign them to inputs in the order of Table 0, Table 1, Table 2, Table 3.
Therefore it is best to use them in the general equation in the order of Table 3, Table 2, Table 1, Table 0.
The program example shown (UAP1096) uses branching (discussed in HLP1086) to select either table 3 or table 4 based on the value read into the stack from P2.
To use a table a floating point value must be in the stack, the table will read this value and return the result to the same stack location.
To Edit Table 3
- Click on table 3 in the program list.
- Click on the 'U' command button that appears.
The process of creating and editing tables is the same as on the user guide HLP0013.
The same table can be used over and over again in the same program if the points are the same.
