Repeat Source and Destination Operands
• Data Type: Word
When S1 (source) and D1 (destination) are designated to repeat, different results are set to 3 operands starting with D1.
• Data Type: Double Word
When S1 (source) and D1 (destination) are designated to repeat, different results are set to 3 operands starting with
D1·D1+1.
Repeat All Source and Destination Operands
• Data Type: Word
When all operands are designated to repeat, different results are set to 3 operands starting with D1.
• Data Type: Double Word
When all operands are designated to repeat, different results are set to 3 operands starting with D1·D1+1.
Note:
When a user program error occurs in any repeat operation, special internal relay M8004 (user program execution
error) and the ERROR LED 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.
