(e) One operand is a symbol whose data type is WORD/DWORD/LWORD, and the other
operand is a symbol whose data type is INT/DINT/LINT. The data length of the operand at
the left side of := must be larger than or equal to the data length of the operand at the right
side of :=.
(f) Both operands are symbols whose data types are REAL/LREAL/STRING. The data
lengths of the operands must be the same.
• Example
Example 1: The value of M0 is assigned to the symbol OUT_0.
Example 2: M0 is set to ON.
Example 3: The value in D2 is added to the value in D1. The sum is stored in D0.
Example 4: 3 is assigned to the symbol DATA.
Example 5: The system judges whether the value of the arithmetic expression 3*2+6* (5+3) is
equal to the value stored in D0. The judgement result is sent to M0.
