I/O Variables
I/O variables are the variables used for sending and receiving I/O signals between the control and
peripheral equipment.
•
Input variables:
The variables representing signals inputted from peripheral equipment such as the operation
panel, the post-process gauging unit, the tool gauging system and the touch sensor.
These signals are called "input bit data".
•
Output variables:
The variables representing signals output from the control to the peripheral equipment such as
indicator lamps and alarm display on the operation panel.
These signals are called "output bit data".
