*1 Modifying a device with an index does not cause a processing delay.
*2 The PC MIX value indicates the average number of commands, including basic commands and data processing commands, which are executed in 1 μs. The greater the value, the faster the processing speed.
*3 Commands used exclusively with the intelligent function units are not included.
*4 The default number of points is indicated. The value can be changed using a parameter.
*5 The number of points when the built-in memory (standard RAM) is used, is indicated. The memory can be expanded using an SRAM card or Flash card. (A Flash card cannot be written from the program.)

When an SRAM card is used, up to 1,041,408 points can be used.
