The read floating point value of the external variable is not a number (NaN).

Description

External variables (V.E. see[EXTV]) can also be assigned values outside of the CNC, e.g. in the PLC. Therefore, when reading a variable of type REAL64, the CNC checks if the variable value is a valid number. This error message is generated when the found number is “not a number” (NaN).
