Circuit Configuration
• Up to two Interrupt Input Units can be
mounted to the CPU Rack. They must
be connected as one of the five Units
immediately next to the CPU Unit. If an
Interrupt Input Unit is connected in any
other position, an Incorrect Unit/Expan-
sion Rack Connection error will occur.
• Set the pulse width of signals input to
the Interrupt Input Unit so they satisfy
the following conditions.
