Legacy DX-9100 Extended Digital Controllers supported an optional XT Extension Module with associated XP Expansion I/O Modules to expand the DX-9100's input and output interfaces. FX-PC controllers do not support the XT/XP modules. Instead, for I/O expansion, the FX-PC controllers support the SA bus for connecting FX-PCs to IOM Expansion I/O modules.

When using an FX-PC controller to replace a DX-9100 controller, you must also replace the XT/XP modules. Either use available I/O interfaces on the FX-PC main controller or add FX-PCX Expansion I/O modules.
