Operands

IMPORTANT: Unexpected operation may occur if:

Output tag operands are overwritten

Members of a structure operand are overwritten

Except when specified, structure operands are shared by multiple instructions.

There are data conversion rules for mixing numeric data types within an instruction. See Data conversions.

Ladder Diagram

Operand	Data Type	Format	Description
SourceA	SINT INT DINT LINT USINT UINT UDINT ULINT REAL LREAL	immediate tag	Value of the dividend
SourceB	SINT INT DINT LINT USINT UINT UDINT ULINT REAL LREAL	immediate tag	Value of the divisor
Dest	SINT INT DINT LINT USINT UINT UDINT ULINT REAL LREAL	tag	Tag to store the result of the instruction.

Major/Minor Faults

A minor fault will occur if:	Fault Type	Fault Code
Source_B = 0	4	4

See Index through arrays for array-indexing faults.

Execution

Condition/State	Action Taken
Prescan	N/A
Rung-condition-in is false	Set Rung-condition-out to Rung-condition-in
Rung-condition-in is true	Set Rung-condition-out to Rung-condition-in Dest = Source A / Source B ^1,2
Postscan	N/A
