MUL / MUL_S

Type	Function Available as standard (non-safety-related) and safety-related type (*_S). For the safety-related type, the safety-related data types (SAFE*) are expected at the formal parameters.
Description	Multiplies the operands connected to the inputs.
Notes	When the multiplication result exceeds the permissible range of the output value, an overflow occurs. Multiplication of a TIME value by a larger data type (type casting): Before the multiplication operation is performed, the larger data type (e.g., LINT, ULINT, LREAL) connected to IN2 is converted (casted) to the smaller TIME data type. Overloaded function. The function can operate on various input data types. The function provides implicit data type conversion at its input and output parameters according to the rules defined by the IEC 61131 standard. Further inputs can be added.
Parameters	Inputs IN1 Data type: ANY_(SAFE)MAGNITUDE Description: First input value. IN2 Data type: ANY_(SAFE)NUM Description: Second input value. Output OUT Data type: ANY_(SAFE)MAGNITUDE Description: Output value.
Error behavior	Error behavior The following table shows the errors which may occur while executing the function and the value returned by the function in the corresponding error case. Error case Output value RFC/NFC/AXC F 3152 Output value AXC F 2152 Overflow for Int input values Overflow for IN1 = time value and IN2 = Int value Overflow value Overflow value Overflow for Real input values Inf+- (depending on input values) Inf+- (depending on input values) Overflow for IN1 = time value and IN2 = Real value (result > ULINT_MAX) T#0s, LT#0ns (ABS(result) > ULINT_MAX / 2) T#-1ms, LT#-1ns (ABS(result) > ULINT_MAX) Real input values: any input = NaN NaN NaN IN1 = time value and IN2 = Real value: any input = NaN T#0, LTIME_MIN T#0, LT#0 IN1/IN2 = any Real or IN1/IN2 = Inf+/Inf- Inf+- (depending on input values) Inf+- (depending on input values) IN1 = TIME value and IN2 = Real value: input Inf+ T#0s T#-1ms IN1 = TIME value and IN2 = Real value: input Inf- T#0s T#1ms IN1 = LTIME value and IN2 = Real value: input Inf+ LTIME_MIN LT#-1ns IN1 = LTIME value and IN2 = Real value: input Inf- LTIME_MIN LT#1ns
Additional information	EN/ENO behavior The POU is only executed if TRUE is applied to the EN input. If EN = FALSE, the POU is not executed and ENO = FALSE indicates the inactivity. If any of the errors listed under "Error behavior" occurs while executing the function, ENO is set to FALSE. Further Info See the topic "General information on execution control with EN/ENO" for further details.
