Repeat Operation in the DIV Instruction
Since the DIV (division) instruction uses two destination operands, the quotient and remainder are stored as described
below. Source operands S1 and S2 and destination operand D1 can be designated to repeat individually or in combination.
When destination operand D1 is not designated to repeat, the final result is set to destination operand D1 (quotient) and
D+1 (remainder). When repeat is designated, consecutive operands as many as the repeat cycles starting with the desig-
nated operand are used.
When only S1 (source) is designated to repeat, the final result is set to destination operands D1 and D1+1.
When only S2 (source) is designated to repeat, the final result is set to destination operands D1 and D1+1.
When only D1 (destination) is designated to repeat, the same result is set to 6 operands starting with D1.
When S1 and S2 (source) are designated to repeat, the final result is set to destination operands D1 and D1+1.
When S1 (source) and D1 (dest.) are designated to repeat, different results are set to 6 operands starting with D1.
When S2 (source) and D1 (dest.) are designated to repeat, different results are set to 6 operands starting with D1.
When all operands are designated to repeat, different results are set to 6 operands starting with D1.
Note: When a user program error occurs in any repeat operation, error indicator ERR1 and special internal relay M304
(user program execution error) are turned on and maintained while operation for other instructions is continued. For the
advanced instruction which has caused a user program execution error, results are not set to any destination.
