*1 Set the device number and the allocating points in multiples of 16. In the case that the number of points is not a multiple of 16, a
parameter setting error occurs in GX Works3.
*2 Because MODBUS devices are long type devices, 2 points are allocated.
Precautions
• The same device cannot be set for a coil and an input.
• The same device cannot be set for an input register and a holding register.
• A parameter setting error occurs in GX Works3 when the total of selected head device number and the allocated points
exceed the valid range for the selected PLC device.
