DeviceNet Gateway
The table below lists the number of positions available for each controller in each PIO pattern, and the
corresponding maximum number of positions that can be registered for the Gateway Unit. Take note that
the number of positions may be limited in some cases.

*1 In an operation mode where position numbers are specified, the number of available positions is
limited according to the PIO pattern selected (via parameter No. 25). (The Gateway can handle a
greater number of positions.)
*2 Since the Gateway can handle 64 positions, the number of positions available for the controller is
limited.
*3 With positioner operation axes under the command specification mode, align the setting of the
controller’s PIO pattern selection parameter with the I/O pattern set by Gateway control signals PPS0
to PPS2. The value that should be set by PPS0 to PPS2 is shown in parentheses after the number of
positions.
