1-1-2 CJ2 CPU Unit Features
z High-speed Processing
High-speed processing times of 0.016 µs for basic instructions, 0.048 µs for special instructions, and
0.99 µs for immediate refreshing, are now possible.
z Large Program Capacity
The CJ2 CPU Units provide a large program capacity of up to 400 Ksteps.
z Large Data Memory Capacity
The CJ2 CPU Units provide a large EM Area capacity of up to 800 Kwords (25 banks).
z Up to 128 Cyclic Tasks
The user program can be divided into up to 128 tasks. Using smaller task programs makes it easier
to structure programs and contributes to shorter cycle times.
The CJ2 CPU Units provide as standard equipment a built-in EtherNet/IP port that supports the same
FINS Ethernet functions as an Ethernet Unit (including features such as a FINS server and time coordi-
nation) as well as the EtherNet/IP open network.
z High-speed, High-capacity Data Links with User-set Refresh Cycles
The CJ2 CPU Units provide high-speed, high-capacity data links, and refresh cycles can be set indi-
vidually for each data link area.
In addition, using the EtherNet/IP DataLink Tool makes it possible to set the data links using an inter-
face similar to that of the Controller Link automatic data link setup.
