The I/O assignment is set on the I/O Assignment tab of the PLC parameter dialog box.
On the I/O Assignment tab, the following items can be set for each slot on the base unit.
• "Type" (module type)
• "Points" (I/O points)
• "Start XY" (start I/O number)
To change the I/O number of the specified slot, setting is allowed only to the number of points.
For other items that are not set, settings are completed based on the installation status of the base unit.
Item Description
Slot
The slot number and location of the slot are displayed. When the base unit is set to auto mode, the base unit number is
indicated in "*", and the slot number is counted from slot 0 of the main base unit.
Type
Select the type of the mounted module from the following:
• Empty (empty slot) • Input (input module) • Hi. Input (high-speed input module) • Output (output module) • I/O Mix
(I/O combined module)
• Intelligent (intelligent function module) • Interrupt (interrupt module)
When the type is not specified for a slot, the type of the actually mounted module applies.
Model Name

• 0 Point • 16 Points • 32 Points • 48 Points • 64 Points • 128 Points • 256 Points • 512 Points • 1024 Points
When the number of points is not specified for a slot, the number of points of the actually mounted module applies. For
empty slots, the number of points set on the PLC System tab of the PLC parameter dialog box is assigned (default: 16
Points).
