FX3G/FX3U/FX3GC/FX3UC Series
Programming Manual - Basic & Applied Instruction Edition
B Instruction Execution Time
B-6 Execution Time on Combination of Applicable Devices and Indexing
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.
Appendix B-6-1 Basic instruction (LD/LDI/AND/ANI/OR/ORI) execution time
•FX3U/FX3UC PLCs
•FX3G/FX3GC PLCs do not support indexing of bit devices and contact instructions with bit specification of word
devices in basic instructions.
Appendix B-6-2 Applied instruction execution time
1. MOV (FNC 12) instruction execution time
•FX3U/FX3UC PLCs
- MOV instruction (16-bit operation)
*1. These combinations are handled as exceptions because high-speed processing is adopted in the technique.
*2. When the instruction is executed for a BFM in a special function block/unit for FX3U/FX3UC Series.
- DMOV instruction (32-bit instruction)
*1. These combinations are handled as exceptions because high-speed processing is adopted in the technique.
*2. When the instruction is executed for a BFM in a special function block/unit for FX3U/FX3UC Series.
