Datasheet

CJ1 series CPU Units 165
Programmable
Controllers
Ample Speed for Advanced Machine Interfaces, Communications, and Data Processing
High-speed Instructions and System Bus
Faster Execution Times (from 20 ns) and Faster
Processing of Frequently Used Instructions
Faster instruction processing includes 0.02 μs for LD and 0.18 μs for
MOV. A complete range of instructions (more than 400) is supported,
more than 100 of which are frequently used special instructions that
can be processed almost as fast as basic instructions, as fast as 0.18
μs for some instructions.
Four Times the Peripheral Servicing and I/O Refresh Speed
Increased efficiency in data transmission between the CPU Unit and
Special I/O Units/CPU Bus Units further improves performance of the
entire system.
Refresh time for CJ-series 64-point Input Units:
0.011 ms (16 times faster)
Refresh time for CJ-series 64-point Output Units:
0.011 ms (8 times faster)
Refresh time for 256 words for Communications Unit:
0.45 ms (4 times faster)
30 Times the Overall Cycle Speed
Example 1: The following example is for 30-Kstep programs (basic
instructions: 50%; MOV instructions: 30%; arithmetic operation
instructions: 20%).
Example 2: The following example is for 10-Kstep programs (basic
instructions: 50%; MOV instructions: 30%; arithmetic operation
instructions: 20%).
