Correspondence Table Of Analog I/O Unit Variables And Cj-Series Cpu Addresses - Omron CJ Series Operation Manual

A-3 Correspondence Table of Analog I/O
Unit Variables and CJ-series CPU
Addresses
When this Unit is used with an NJ-series CPU Unit, the user program uses device variables for CJ-
series Unit with AT specification for the memory used for CJ-series Unit and user-defined variables to
use the Unit functions.
Correspondences regarding word addresses, bit number and device variables for CJ-series Unit and
user-defined variables between the I/O memory of the CJ-series CPU Unit and memory used for CJ-
series Unit of the NJ-series CPU Unit are shown below.
Start address of the words allocated in Special I/O Unit in CIO Area: n = 2000 + Unit number × 10 (Unit

Additional Information
• If the same unit number is set for more than one Special I/O Unit, a "Duplicate Unit Number"
major fault level Controller error occurs and the Unit will not operate.
• After correcting the unit number setting, cycle the power to the Controller.
