Note 1) The processing speed is the same even when the device is indexed.
Note 2) The PC MIX value is the average number of instructions such as the basic and data processing instructions executed in 1μs. A larger value indicates a higher
processing speed.
Note 3) Intelligent function module dedicated instructions are not included.
Note 4) Indicates the number of points in the default state. This can be changed with the parameter.
Note 5) Indicates the number of points when using the built-in memory (standard RAM). This can be expanded with the SRAM card or Flash card. (Writing from the program
is not possible with the Flash card.) Up to 4184064 points can be used with the SRAM card.
Note 6) The USB port terminal is mini-B.
