All values related to input settings, transformations and their coefficients are applied only after uploading and cold restart of the PLC.
During recovery, a cold restart is not a problem (during this, the current values from the PLC runtime are lost and all variables are set to the default values from the source code). Later in operation, however, we want to keep the current values, ie avoid a cold restart. Then you can proceed as follows:
With the Identity transformation, auxiliary variables with the type of linearization, coefficients, etc. are deleted during compilation. Their re-establishment already applies new values. If we only changed, for example, the type of linearization curve or the values of Pre_K, Pre_Q, X1, X2, etc., the transformation would always remain in the code and after uploading the program and a warm restart, the current (old) values in the PLC would be used.
