XPice permits plain vanilla digital I/O expansion that is both economical and blends virtually seamlessly into the programming.

XPice is a kind of super SPiceX. With XPice we combine the hardware simplicity of SPiceX with the simple programming of I/O points that are part of the main controller board.

A XPice board is a simple shift-register based bulk I/O expansion board. Most XPice boards are capable of being cascaded (daisy-chained), so you could have more than one hung off a SPLat controller. The XBIO16, HIO16 and XIRO16 expansion boards are XPice.

XPice enabled controllers will automatically recognise XPice expansion boards when they are connected. They will also report themselves to SPLat/PC with the expansion included.

The controller will appear on the SPLat/PC screen with the additional I/O showing in the I/O window, and the additional I/O can be programmed with regular instructions like GoIfInOn, INPUT, ON, OFF etc.
