5238-E P-297SECTION 12 USER TASK4-2. I/O VariablesI/O variables are the variables used for sending and receiving I/O signals between the control andperipheral equipment.• Input variables:The variables representing signals inputted from peripheral equipment such as the operationpanel, 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 asindicator lamps and alarm display on the operation panel.These signals are called "output bit data".4-2-1.
