6.1 Common Basic Functions
6.1.1 I/O Signals
(1) Configuration of I/O Contact Signals
In the case of Contact I/O Interface
The contact I/O signals on CN4 are called physical (hard) I/O, consisting of 12 inputs and 6
outputs. When shipped from the factory, hard I/O is assigned as shown in " Hard I/O
Assignment, Default Settings" in 6.1.1 (4), "Physical (Hard) I/O Assignment, Logic Setting
Method."
Hard I/O can be assigned from any virtual logic contact signal, called logic I/O (48 contact
inputs and 32 contact outputs) (using the hard I/O assignment function).
