 converts values that are transmitted to numeric tags

View Designer converts values that are being transmitted to numeric tags in the controllers, such as DIN, SINT, or REAL, into a number based on the following rules:
  • If the first character is 0 and the second character is an x, the rest of the data is treated as a hexadecimal number (base 16).
  • If the first character is 0 and the second character is a digit from 0 to 7, the rest of the data is treated as an octal number (base 8).
  • If the value contains a decimal point, the value is treated as a floating point input. Based on the target tag type, the value may be rounded.
  • If the first character is a digit from 1 to 9, the rest of the value is treated as a base 10 number.
  • If value contains the letter e, the characters that follow it are treated as the exponent (base 10) for the number.
  • If the first character is a + or -, it is treated as a sign for the number. The resulting number is based on the rules described above. For example, -020 is treated as a negative octal number.
  • If the value contains any character except digits (0 to 9), ., +, -, or e, it is treated as an error.
