*1: Direct I/O instruction is effective only for the basic unit inputs/outputs.
*2: The expanded data transfer (XFER) instruction supports some special functions. It also supports the communication function. The execution speed shown in the above table is for the EEPROM read/write function. When the Inverter connection mode is selected, the execution speed of this instruction is typically 150 ∝ s (max. 500 ∝ s).
NOTE | The index modification is available for some instructions. The values in the |
| |
| execution speed column show the execution time without index |
| modification. |
| If index modification is used, approx. 20 ∝ s is added per one indexed |
| operand. |
