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.

ATTENTION
For detailed information on configuring and wiring an MS/TP Bus, FC bus, and SA bus, refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034).

Terminal blocks and bus ports

See Figure 1 for terminal block and bus port locations on the expansion module. Observe the following guidelines when wiring an expansion module:

Input and output Terminal Blocks

Most of the input terminal blocks are mounted on the bottom of the controller and the output terminal blocks are mounted on the top of the controller.
See Table for more information about I/O terminal functions, requirements, and ratings.

SA/FC bus terminal block

An IOM can be connected to an SA bus or an FC bus, but not both buses simultaneously. The SA/FC bus terminal block is a removable, 4-terminal plug that fits into a board-mounted jack.
When connecting the IOM to an FC bus, wire the bus terminal block plugs on the expansion module, and the other controller and expansion modules in a daisy-chain configuration using 3-wire twisted, shielded cable as shown in Figure 4.
Figure 4: FC bus terminal block wiring
Mise En Garde: Risque de dégâts matériels:
Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils for­mant un court-circuit ou connectés de façon incor­recte risquent d'endommager irrémédiablement l'équipement.
Important: Do not exceed the controller electrical ratings. Exceeding controller electrical ratings can result in permanent damage to the controller and void any warranty.
Important: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations.
IOM3733 Input/Output Module Installation Guide4
When connecting the IOM to an SA bus, wire the bus terminal block plugs on the expansion module and other SA bus devices in a daisy-chain configuration using 4-wire twisted, shielded cable as shown in Figure 5.
Figure 5: SA bus terminal block wiring
Note: The SA PWR/SHLD terminal does not
supply 15 VDC. The SA PWR/SHLD terminal is isolated and can be used to connect (daisy chain) the 15 VDC power leads on the SA bus (Figure 5) or the cable shields on the FC bus (Figure 4). The SA bus supervisor (FAC, FEC, or VMA) supplies 15 VDC to devices on the SA bus requiring power.

Supply Power Terminal Block

The 24 VAC supply power terminal block is a gray, removable, 3-terminal plug that fits into a board­mounted jack on the top right of the controller.
Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the terminal plug as shown in the following figure:
Figure 6: 24 VAC Supply Power Terminal Block Wiring
Note: The supply power wire colors may
be different on transformers from other manufacturers. Refer to the transformer manufacturer’s instructions and the project installation drawings for wiring details.
Important: Connect 24 VAC supply power to the controller and all other network devices so that transformer phasing is uniform across the network devices. Powering network devices with uniform 24 VAC supply power phasing reduces noise, interference, and ground loop problems. The controller does not require an earth ground connection.

Setup and Adjustments

Setting the device address

Metasys expansion modules are master devices on MS/TP (SA or FC) buses. Before operating an expansion module on a bus, set a valid and unique device address for each expansion module on the bus. You set an expansion module's device address by setting the positions of the switches on the DIP switch block at the top of the expansion module. Device addresses 4 through 127 are the valid addresses for these expansion modules. The following table describes the FC bus and SA bus device addresses for Johnson Controls MS/TP communications bus applications.
Table 6: SA/FC Bus Device Address Descriptions
Device Address
0 (Switch 128
Off)
1-3 (Switch 128
Off)
4-127 (Switch 128
Off)
The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1. Switches 64 through 1 are device address switches. Switch 128 must be set to OFF for all hard-wired SA and FC Bus applications.
Figure 8: Device address DIP switch Block set to address 21
Use on Descriptions
Reserved for FC Bus Supervisory Controller (not for use on controllers or expansion modules).
Reserved for peripheral devices (not for use on controllers or expansion modules).
Used for MSTP master devices (controllers and expansion modules) that are hardwired to an SA bus or FC bus.
Note: Metasys field controllers ship with switch 128 ON and the remaining address switches off rendering the controllers wired subordinate devices, which do not operate on MSTP buses, but do not interfere with bus operation. Set a valid and unique device address on the expansion module before applying power to the expansion module on the bus.
To set the device addresses on Metasys expansion modules, complete the following steps:
1. Set all of the switches on the address DIP
switch block (128 through 1) to OFF.
2. Set one or more of the seven address switches
(64 though 1) to ON, so that the sum of the switch numbers set to ON equals the intended device address, and ensure that switch 128 remains set to OFF.
Note: To do this, set the highest number switch that is less than or equal to the intended device address to ON. Then continue setting lower numbered switches until the total equals the intended address. For example, if the intended device address is 21, set switches 16, 4, and 1 to ON (16+4+1= 21) and all other switches to OFF.
3. Set a unique and sequential device address for
each of the expansion module connected on the SA or FC bus, starting with device address 4.
Note: To ensure the best bus performance, set sequential device addresses with no gaps in the device address range (for example, 4, 5, 6, 7, 8,
9). The controllers/expansion modules do not need to be physically connected on the bus in their numerical device address order.
4. Write each expansion module's device address
on the white label below the DIP switch block on the expansion module's cover.

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.
IOM3733 Input/Output Module Installation Guide10
Important: Disconnect all power sources to the expansion module before removing the 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.
Note: For detailed information regarding EOL termination rules and EOL switch settings on FC buses, refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034).
3. If the controller is a terminating device on
the FC bus, set the EOL switch to ON. If the controller is not a terminating device on the bus, set the EOL switch to Off.
When a controller is connected to power with its EOL switch set to ON, the amber EOL LED on the controller cover is lit.
To remove the expansion module cover, complete the following steps:
1. Place your fingernails under the two cover lift tabs (Figure 1) 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 controller has an EOL switch, which, when set to ON, sets the controller as a terminating device on the bus. The default EOL switch position is OFF.
Figure 9: End-of-Line switch positions

Commissioning the Controllers

Commission BACnet MS/TP field controllers with the controller (CCT) software, either via a Bluetooth Wireless Commissioning Converter, a ZFR wireless adapter (BACnet MS/TP only), or in BACnet routing mode when connected to an NAE or NCE.
Note: N2-capable controllers do not support Zone Bus or XT Bus. They do not support wireless connections to the N2 Bus.
Refer to the Controller Tool Help (LIT-12011147) for detailed information on commissioning field controllers.

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).
®
To set the EOL switch on a field controller, complete the following steps:
1. Determine the physical location of the field controller on the FC bus.
2. Determine if the controller must be set as a terminating device on the bus.
