*1: Direct I/O instruction is effective only for the basic unit inputs/outputs.<br />

*2: The expanded data transfer (XFER) instruction supports some special functions. It<br />

also supports the communication function. The execution speed shown in the<br />

above table is for the EEPROM read/write function. When the Inverter connection<br />

mode is selected, the execution speed of this instruction is typically 150 µs (max.<br />

500 µs).<br />

NOTE<br />

The index modification is available for some instructions. The values in the<br />

execution speed column show the execution time without index<br />

modification.<br />

If index modification is used, approx. 20 µs is added per one indexed<br />

operand.<br />
