Specifications

Note 1) The processing time will not be delayed if the devices are indexed.
Note 2) The PC MIX value is the average number of instructions, such as basic instructions or data processing instructions, which can be executed in 1ms. The processing speed will rise
as the value increases.
Note 3) The intelligent function module's dedicated instructions are not included.
Note 4) The number of control loops is limited by the combination of the device memory capacity (using 128 words/loop) and control cycle.
Note 5) Indicates the number of points in the default state. This can be changed with the parameters.
Note 6) Indicates the number of points when using the built-in memory (standard RAM).
This can be expanded with the SRAM card and Flash card. (Writing from the program is not possible when using the Flash card.)
Up to 1041408 points can be used when using the SRAM card.
