IOM3733 Input/Output Module Installation
Guide
Application
The MS-IOM3733 input/output expansion module
is part of the
Metasys
®
system Field Equipment
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 IOM3733 model is only available
in certain regions. Contact your local Johnson
Controls representative for more information.
IOM expansion modules operate on an RS-485
BACnet
®
MS/TP bus and integrate into IOMs
communicate using the BACnet MS/TP protocol
when directly connected to the FC bus.
Note:
With Release 10.1 and later of the
Controller Configuration Tool (CCT), VMAs, FECs,
and FACs can be configured to communicate
by 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.
