XP-910x Expansion Modules

Introduction	The XT-9100 Extension Module and its expansion modules have been
	designed to provide additional input and output capacity within Metasys®
	Networks and specifically for the DX-9100 Extended Digital Controller.
	The XT-9100 module provides the communication interface and the
	XP modules provide the analog and digital inputs and outputs.

A Supervisory System communicates with an XT-9100 via the N2 Bus or Bus 91*. Each XT-9100, depending on its expansion module combination, can have up to 16 inputs/outputs, eight of which may be analog.

The DX-9100 communicates with the XT-9100 via the XT-Bus, and when the DX-9100 is connected to an N2 Bus (or Bus 91), data from the XT-9100 is available to a Supervisory System. Up to eight XT-9100 modules can be connected to the XT-Bus. Each XT-9100 provides, depending on the type of the connected XP expansion modules, either eight analog points or eight digital points, extending the input/output of a DX-9100 by up to 64 remote input/outputs. Modules with 16 input/outputs may also be connected, provided that the total number of remote input/output points on the DX-9100 does not exceed 64.

Configuration of the XT-9100 is achieved by using a personal computer with GX-9100 Graphic Configuration Software (GX Tool) supplied by Johnson Controls. When the serial interface of the XT-9100 is connected directly to the N2 Bus (Bus 91), the GX-9100 will download and upload configurations over the N2 Bus (Bus 91). When the serial interface of the XT-9100 is connected to the XT Bus, the GX-9100 will download and upload configurations via the N2 Bus (Bus 91) connected to the DX-9100 to which the XT-Bus is connected. The DX-9100 retransmits configuration data to the XT-9100 on its XT-Bus.
