I/O signal
• Q170MSCPU's internal I/F
(Note-1)
(Input 4 points, output 2 points)
• PLC I/O module
• Intelligent function module
• Built-in interface in Motion CPU
(Note-1)
(Input 4 points)
• PLC I/O module
• Intelligent function module
(Note-1): Real input device (PX) or real output device (PY) is in units of 16 points.
• Real input (PX) : 4 points + Dummy (Unsable: Fixed at 0) 12 points
• Real output (PY) : 2 points + Dummy (Unsable: Fixed at 0) 14 points
(Example) When the first I/O No. is set to 0(H).
• PX0 to PX3 (Real input), PX4 to PXF (Unsable: Fixed at 0)
• PY0 to PY1 (Real output), PY2 to PYF (Unsable: Fixed at 0)
