Johnson Controls IOM2723 Installation Manual

Application
The MS-IOM2723 input/output expansion module
is part of the Metasys
®
Controller family. Input/Output expansion modules
(IOMs) expand the number of Input/Output points
connected to either a Network Automation Engine
(NAE), Network Control Engine (NCE), Advanced
Application Field Equipment Controller (FAC), Field
Equipment Controller (FEC), or Variable Air Volume
Modular Assembly (VMA) to monitor and control a
wide variety of HVAC equipment.
Note: The IOM2723 model is only available
in certain regions. Contact your local Johnson
Controls representative for more information.
IOMs operate on an RS-485 BACnet
and integrate into Johnson Controls
party BACnet systems. IOMs communicate using the
BACnet MS/TP protocol when directly connected to
the FC Bus.
Note: With Release 10.1 or later of the
Controller Configuration Tool (CCT), VMAs, FECs,
and FACs can be configured to communicate
using either the BACnet MS/TP or the N2 field
bus networking protocol. The operation of
the IOM is not affected by the selection of the
BACnet MS/TP or the N2 protocol in the host
controller, when the IOM is connected to the
host controller using the SA bus.
