*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
µ
s (max.
500
µ
s).
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
µ
s is added per one indexed
operand.
