CJ-series Basic I/O Units Section 3-6
Applicable Units Either of the following Interrupt Input Units can be used with a CJ1-H or CJ1M
CPU Unit. (Interrupt Input Units cannot be mounted to CJ1 CPU Units.)
Application Precautions
1. Interrupt Input Units must be mounted in the locations described below.
• CJ1-H CPU Units
All Interrupt Input Units must be connected in the CPU Rack and must be
connected in any of the five positions immediately to the right of the CPU
Unit. The interrupt input function will not be supported if an Interrupt Input
Unit is mounted to an Expansion Rack. If connected in any other position
or to an Expansion Rack, and I/O setting error (fatal) will occur.
• CJ1M CPU Units
All Interrupt Input Units must be connected in the CPU Rack and must be
connected in any of the three positions immediately to the right of the
CPU Unit. The interrupt input function will not be supported if an Interrupt
Input Unit is mounted to an Expansion Rack. If connected in any other
position or to an Expansion Rack, and I/O setting error (fatal) will occur.
2. If the Interrupt Input Units are not connected in the correct positions, an er-
ror will occur when the I/O tables are generated from the CX-Programmer.
A40110 will turn ON to indicate an I/O setting error and A40508 will turn
ON to indicate that an Interrupt Input Unit is in the wrong position.
Note Even if a Unit is physically in one of the correct positions, a Dummy Unit can
be registered in the I/O table, causing a Unit to be defined in a position differ-
ent from its physical position.
There are limits to the number of Interrupt Input Units that can be mounted.
