Both the S7-200 and the S7-300 use the same methode for displaying floats (ANSI/IEEEstandard754-1985). This means a 23bit number value, a 8 bit exponent and 1 bit sign. (see wiki ) I could find a remark that floating point numbers als accurate to 6 decimal places for both the S7-200 and the S7-300. So in theory there should not be a differece between the 2 PLC's I don't know the code you are using and what type off math's are made. But might be a limitation / bug in one off the math processing units. |
