Input Device Connection
Table 10A.L lists the terminals of the digital I/O input terminal strips. You
can assign an input device to each terminal. Use the blank space beside
each terminal number to indicate any terminal assignments that are made.
The terminal assignments will have to correspond to the terminal
assignments of the digital I/O in the PAL I/O Assignment file. The I/O
assignment file will have to be edited if the terminal assignments do not
correspond. Refer to the 9/Series CNC 9/230, 9/260, and 9/290 PAL
Reference Manual, publication 8520-4.3, for more information.
