*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 x 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)
The following time must be added when using Pulse I/O Modules with a CJ2M CPU Unit:
10 µs × Number of Pulse I/O Modules
*2 This applies when high-speed interrupts are used.
*3 Supported only by CJ2M CPU Units with unit version 2.0 or later. A Pulse I/O Module must be mounted.
