Circuit Configuration
• Up to two Interrupt Input Units can be
mounted to the CPU Rack, but they
must be connected as one the five
Unit
*1
immediately next to the CPU
Unit. If an Interrupt Input Unit is con-
nected in any other position, an I/O
setting error will occur.
• Set the pulse width of signals input to
the Interrupt Input Unit so they satisfy
the following conditions.
*1 With the CJ2JH-CPU6@-EIP CPU
Units, the Unit must be mounted as
one of the four Units immediately
next to the CPU Unit.
