Processing details
■Operation processing
• These functions multiply the INT, DINT, REAL, or LREAL data type values input to (s1) to (s28) ((s1)(s2)(s28)), and
output the operation result, in the same data type as (s), from (d).
Ex.
Data type: INT
(s1)
100 ×
INT
• Input an INT, DINT, REAL, or LREAL data type value to (s1) to (s28).
• If an underflow or overflow occurs in the operation result, the output from (d) will be as follows.
Data type: INT
• Even if an underflow or overflow occurs, no
operation error is issued. When MUL_E is used,
ENO outputs TRUE.
• Even if the operation result is outside the INT data
type range, the INT data type value is output; (In
this case, the output value is of INT data type with
the upper 16 bits deleted although the operation
result is a DINT data type value.)
• If the operation result is outside the INT data type
range, convert the input value to the DINT data
type by using the INT_TO_DINT function, and
then perform operation.

INT
Data type: DINT
• Even if an underflow or overflow occurs, no
operation error is issued. When MUL_E is used,
ENO outputs TRUE.
• Even if the operation result is outside the DINT
data type range, the DINT data type value is
output; (In this case, the output value is of DINT
data type with the upper 32 bits deleted although
the operation result is 64-bit data.)
• If the operation result is outside the DINT data
type range, convert the input value to the REAL
data type by using the DINT_TO_REAL function,
and then perform operation.
