Repeat Operation in the Data Comparison Instructions
The following examples use the CMP>= instruction of word and double word data. Repeat operation for all other data comparison
instructions and other data types is the same as the following examples.
When the repeat operation is enabled, repeated comparison results of CMP instructions can be selected from AND or OR operation,
and the result is output to an output or internal relay.
Repeat One Source Device
When only S1 (source) is designated to repeat, source devices (as many as the repeat cycles, starting with the device designated
by S1) are compared with the device designated by S2. The comparison results are ANDed or ORed and set to the destination
device designated by D1.

Repeat Two Source Devices
When S1 (source) and S2 (source) are designated to repeat, source devices (as many as the repeat cycles, starting with the
devices designated by S1 and S2) are compared with each other. The comparison results are ANDed or ORed and set to the
destination device designated by D1.
