CJ-series High-speed Counter Units Operation Manual for NJ-series CPU Unit(W492)
With the NJ Series, device variables for CJ-series Unit are used for the Counter Unit functions.
The following tables show how the words and bits of CJ-series I/O memory or the NJ-series memory
used for CJ-series Unit correspond to the NJ-series device variables for CJ-series Unit.
Start address of special I/O Unit area: n = 2000 words + Unit number
×
10 (Unit number: 0 to 92)
Start address of the special I/O Unit DM area: m = Unit number
×
100 (Unit number: 0 to 92)
Additional Information
• If two or more Special I/O Units are set to an identical Unit number or if one Special I/O Unit is
set to areas of plural Unit numbers, the CPU Unit has a major fault level error, a duplicated Unit
number error, and stops operation.
• After correcting the Unit number setting, cycle the power to the Controller.
• One High-speed Counter Unit occupies allocation areas of four Unit numbers. Be sure that no
Unit numbers are duplicated.
To avoid duplication, when you set a High-speed Counter Unit to the Unit number "n", set the
next Special I/O Unit to the Unit number "n + 4".
