Table 7: SA/FC bus device address descriptions
Device
Use on description
address
Reserved addresses for wired subordinate devices
(not for use on controllers).
0 to 3
Note: Controllers ship with switch 128 ON
(Switch 128
and the remaining address switches off
ON)
rendering the controllers wired subordinate
devices, which do not operate on MS/TP
buses.
Valid for MS/TP Master controllers on wireless FC
Buses only.
Note: Do not connect a controller with switch
128 ON to an active (hard-wired) SA or
4 to 127
FC bus. When a controller with switch 128
(Switch 128
ON and a device address from 4 to 127 is
ON)
connected to a wired field bus, the entire
field bus is rendered inoperable until the
controller is disconnected or switch 128 is set
to Off.
Removing the expansion module cover
Important: Electrostatic discharge can damage
expansion module components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid damaging
the expansion module.
Important: Disconnect all power sources to
the expansion module before removing cover
and changing the position of any jumper or the
EOL switch on the expansion module. Failure to
disconnect power before changing a jumper or
EOL switch position can result in damage to the
expansion module and void any warranties.
The expansion module cover is held in place by four
plastic latches that extend from the base and snap
into slots on the inside of the housing cover.
To remove the expansion module cover, complete
the following steps:
1. Place your fingernails under the two cover lift tabs
on the sides of the housing cover and gently pry the
top of the cover away from the base to release the
cover from the two upper latches.
2. Pivot the top of the cover further to release it from
the lower two latches.
3. Replace the cover by placing it squarely over the
base, and then gently and evenly push the cover
onto the latches until they snap into the latched
position.
Setting the End-of-Line (EOL) switch
Each expansion module has an EOL switch, which when
set to ON, sets the expansion module as a terminating
device on the bus. See Figure 1 for the EOL switch
location. The default EOL switch position is OFF.
Figure 9: End-of-Line switch positions
To set the EOL switch on an expansion module, complete
the following steps:
1. Determine the physical location of the expansion
module on the SA or FC bus.
2. Determine if the expansion module must be set as a
terminating device on the bus.
Note: The EOL termination rules for SA buses
and FC buses are different. Refer to the MS/TP
Communications Bus Technical Bulletin (LIT-12011034)
for detailed information regarding EOL termination
rules and EOL switch settings on SA and FC buses.
3. If the expansion module is a terminating device
on the FC bus, set the EOL switch to ON. If the
expansion module is not a terminating device on the
bus, set the EOL switch to OFF.
When an expansion module is connected to power with its
EOL switch set to ON, the amber EOL LED on the expan-
sion module cover is lit.
Commissioning
You commission expansion modules with CCT software,
using a Bluetooth Wireless Commissioning Converter
(BTCVT), through Mobile Access Portal (MAP) Gateway
at version 4.2 or above, or in BACnet router mode when
connected to an NAE or NCEa Supervisory Controller.
Refer to the Controller Tool Help (LIT-12011147) for detailed
information on commissioning expansion modules.
Note: To configure the IOM on the Field Controller
(FC) bus, use CCT 10.4 release mode.
Note: The MAP Gateway serves as a replacement for
the BTCVT, which is no longer available for purchase,
but continues to be supported.
Firmware Package File
The MS-FCP-0 equipment controller firmware package
files are required for CCT to configure and commission
the controllers. The firmware package files also allow you
to upgrade an existing controller to the latest firmware
release available for that controller.
Beginning at CCT Release 13, the firmware package files
are orderable separately; they are not included with CCT.
They are obtained from the Metasys software licensing
portal, and are loaded and licensed on the computer/
server that is running CCT.
For additional information about the firmware
package files, refer to the CCT Installation Instructions
(LIT-12011259).
