IEC operator⮫ “Overview”: Division of one variable by another of the types: BYTE, WORD, DWORD, SINT, USINT, INT, UINT, DINT, UDINT, REAL and LREAL.
Example in ST:
var1 := 8/2;
Example in FBD:
If you define functions in your project with the names CheckDivByte, CheckDivWord, CheckDivDWord and CheckDivReal, you can use them to check the value of the divisor if you use the operator DIV, for example to avoid a division by 0. The functions must have the above listed names.
NOTICE
Note that different target systems may behave differently concerning a division by zero!
