*1
The following times are added if EtherNet/IP data tag links are used for the CJ2H-CPU6_-EIP.
Normal operation: 100 µs + Number of transfer words × 0.33 µs
High-speed interrupt function enabled: 100 µs + Number of transfer words × 0.87 µs
The following time must be added when using EtherNet/IP tag data links for the CJ2M-CPU3_.
100 µs + (Number of words transferred × 1.8 µs)
*2
This applies when high-speed interrupts are used.
*3
A960 to A1471 and A10000 to A11535 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not specifically support the CJ2 CPU Units.
*4
Bits in the EM Area can be addressed either by bit or by word. These bits cannot be addressed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not specifically support the
CJ2 CPU Units.
*5
EM banks D to 18 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not specifically support the CJ2 CPU Units.
*6
With CJ2H CPU Units with unit version 1.2 or later, force-setting/resetting bits in the EM Area is possible either for banks that have been specified for automatic address allocation or for banks
specified for the EM Area force-set/reset function. With CJ2M CPU Units, force-setting/resetting bits in the EM Area is possible only for banks specified for the EM Area force-set/reset function.
*7
This data type cannot be used in Function blocks.
*8
This data type can be used only in Function blocks.
*9
Supported only when CX-Programmer version 9.0 or higher is used.
*10
Supported only by the CJ2H-CPU6_-EIP and CJ2M-CPU3_.
