Appendix B-6 Execution Time on Combination of Applicable Devices and
Indexing
In examples shown below for basic instructions, the MOV instruction and data comparison instructions, the instruction
execution time varies depending on the combination of target devices and absence/presence of indexing.
The combinations of target devices marked with "*1" and "*2" are handled as exceptions because high-speed
processing is adopted in the technique.

PLCs do not support indexing of bit devices and contact instructions with bit specification of word devices in
basic instructions.
