Repeat Operation in the ADD and SUB Instructions
Source devices S1 and S2 and destination device D1 can be assigned to repeat individually or in combination. When destination
device D1 is not set to repeat, the final result is set to destination device D1. When repeat is assigned, as many consecutive
devices as the repeat cycles, starting with the designated device, are used. Since the repeat operation works similarly on the ADD
(addition) and SUB (subtraction) instructions, the following examples are described using the ADD instruction.
Repeat One Source Device
• Data Type: Word and Integer
When only S1 (source) is assigned to repeat, the final result is set to destination device D1.
• Data Type: Double Word, Long, and Float
When only S1 (source) is assigned to repeat, the final result is set to destination device D1·D1+1.
Repeat Destination Device Only
• Data Type: Word and Integer
When only D1 (destination) is assigned to repeat, the same result is set to 3 devices starting with D1.
• Data Type: Double Word, Long, and Float
When only D1 (destination) is assigned to repeat, the same result is set to 3 devices starting with D1·D1+1.
Repeat Two Source Devices
• Data Type: Word and Integer
When S1 and S2 (source) are assigned to repeat, the final result is set to destination device D1.
• Data Type: Double Word, Long, and Float
When S1 and S2 (source) are assigned to repeat, the final result is set to destination device D1·D1+1.
