IOM3733 Input/Output Module Installation Guide

Application

The MS-IOM3733 input/output expansion moduleis part of the Metasys system Field EquipmentController family. Input/Output expansion modules(IOMs) expand the number of input/outputpoints connected to either a General PurposeController(CGM), VAV Box Controllers (CVM), SNC,SNE, Network Automation Engine (NAE), NetworkControl Engine (NCE), Advanced Application FieldEquipment Controller (FAC), Field EquipmentController (FEC), or Variable Air Volume ModularAssembly (VMA) to monitor and control a widevariety of HVAC equipment.

Note: The IOM3733 model is only availablein certain regions. Contact your local JohnsonControls representative for more information.

IOM expansion modules operate on an RS-485BACnet® MS/TP bus and integrate into IOMscommunicate using the BACnet MS/TP protocolwhen directly connected to the FC bus.

Note: With Release 10.1 and later of theController Configuration Tool (CCT), VMAs, FECs,and FACs can be configured to communicateby using either the BACnet MS/TP or the N2field bus networking protocol. The operation ofthe IOM is not affected by the selection of theBACnet MS/TP or the N2 protocol in the hostcontroller, when the IOM is connected to thehost controller using the SA bus.

Terminal blocks and bus ports

See Figure 1 for terminal block and bus portlocations on the expansion module. Observe thefollowing guidelines when wiring an expansionmodule:

Input and output terminal blocksThe input terminal blocks are mounted on thebottom of the expansion module and the outputterminal blocks are mounted on the top of theexpansion module.

SA/FC bus terminal blockAn IOM can be connected to an SA bus or an FC bus,but not to both buses simultaneously. The SA/FC


bus terminal block is a removable, 4-terminal plugthat fits into a board-mounted jack.When connecting the IOM to an FC bus, wire thebus terminal block plugs on the expansion module,and the other expansion modules in a daisy-chainconfiguration using 3-wire twisted, shielded cable asshown in the following figure.

Figure 4: FC bus terminal block wiring

When connecting the IOM to an SA bus, wire the busterminal block plugs on the expansion module andother SA bus devices in a daisy-chain configurationusing 4-wire twisted, shielded cable as shown inFigure 5.

Figure 5: SA bus terminal block wiring

Note: The SA PWR/SHLD terminal does notsupply 15 VDC. The SA PWR/SHLD terminalis isolated and can be used to connect (daisychain) 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 supplies 15VDC to devices on the SA bus requiring power.

Supply power terminal blockThe 24 VAC supply power terminal block is a gray,removable, 3-terminal plug that fits into a board-mounted jack on the top right of the expansionmodule.Wire the 24 VAC supply power wires from thetransformer to the HOT and COM terminals on theterminal plug as shown in Figure 6. The middleterminal on the supply power terminal block is notused.

Figure 6: 24 VAC supply power terminal blockwiring

Note: The supply power wire colors maybe different on transformers from othermanufacturers. Refer to the transformermanufacturer’s instructions and the projectinstallation drawings for wiring details.

Important: Connect 24 VAC supply power tothe expansion module and all other networkdevices so that transformer phasing is uniformacross the network devices. Powering networkdevices with uniform 24 VAC supply powerphasing reduces noise, interference, andground loop problems. The expansion moduledoes not require an earth ground connection.

Setup and AdjustmentsSetting the device address

Metasys expansion modules are master deviceson MS/TP (SA or FC) buses. Before operating anexpansion module on a bus, set a valid and uniquedevice address for each expansion module onthe bus. You set an expansion module's deviceaddress by setting the positions of the switches onthe DIP switch block at the top of the expansionmodule. Device addresses 4 through 127 are thevalid addresses for these expansion modules.The following table describes the FC bus and SAbus device addresses for Johnson Controls MS/TPcommunications bus applications.Table 6: SA/FC Bus Device Address DescriptionsDeviceAddress Use on Descriptions

0(Switch 128Off)

Reserved for FC Bus SupervisoryController (not for use oncontrollers or expansion modules).

1-3(Switch 128Off)

Reserved for peripheral devices(not for use on controllers orexpansion modules).

4-127(Switch 128Off)

Used for MSTP master devices(controllers and expansionmodules) that are hardwired to anSA bus or FC bus.

The DIP switch block has eight switches numbered128, 64, 32, 16, 8, 4, 2, and 1. Switches 64 through 1are device address switches. Switch 128 must be setto OFF for all hard-wired SA and FC Bus applications.

Figure 8: Device address DIP switch Block set toaddress 21

Note: Metasys expansion modules ship withswitch 128 ON and the remaining addressswitches off rendering the expansion modulewired subordinate devices, which do notoperate on MSTP buses, but do not interferewith bus operation. Set a valid and uniquedevice address on the expansion modulebefore applying power to the expansionmodule on the bus.

To set the device addresses on Metasys expansionmodules, 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 theswitch numbers set to ON equals the intendeddevice address, and ensure that switch 128remains set to OFF.

Note: To do this, set the highest numberswitch that is less than or equal to theintended device address to ON. Thencontinue setting lower numbered switchesuntil the total equals the intendedaddress. For example, if the intendeddevice address is 21, set switches 16, 4,and 1 to ON (16+4+1= 21) and all otherswitches to OFF.

3. Set a unique and sequential device address foreach of the expansion module connected onthe SA or FC bus, starting with device address 4.

Note: To ensure the best busperformance, set sequential deviceaddresses with no gaps in the deviceaddress range (for example, 4, 5, 6, 7, 8,9). The controllers/expansion modules donot need to be physically connected onthe bus in their numerical device addressorder.

4. Write each expansion module's device addresson the white label below the DIP switch blockon the expansion module's cover.

Removing the expansion modulecover

About this task:


Important: Electrostatic discharge can damageexpansion module components. Use properelectrostatic discharge precautions duringinstallation, setup, and servicing to avoiddamaging the expansion module.

Important: Disconnect all power sources tothe expansion module before removing thecover and changing the position of any jumperor the EOL switch on the expansion module.Failure to disconnect power before changinga jumper or EOL switch position can result indamage to the expansion module and void anywarranties.

The expansion module cover is held in place byfour plastic latches that extend from the baseand snap into slots on the inside of the housingcover.

To remove the expansion module cover,complete the following steps:

1. Place your fingernails under the two coverlift tabs (Figure 1) on the sides of the housingcover and gently pry the top of the cover awayfrom the base to release the cover from thetwo upper latches.

2. Pivot the top of the cover further to release itfrom the lower two latches.

3. Replace the cover by placing it squarely overthe base, and then gently and evenly push thecover onto the latches until they snap into thelatched position.

Setting the End-of-Line (EOL) switch

About this task:Each expansion module has an EOL switch, which,when set to ON, sets the expansion module as aterminating device on the bus. The default EOLswitch position is OFF.

Figure 9: End-of-Line switch positions

To set the EOL switch, complete the following steps:

1. Determine the physical location of theexpansion module on the FC bus.

2. Determine if the expansion module must beset as a terminating device on the bus.

Note: For detailed information regardingEOL termination rules and EOL switchsettings on FC buses, refer to the MS/TP Communications Bus Technical Bulletin(LIT-12011034).

3. If the expansion module is a terminatingdevice on the FC bus, set the EOL switchto ON. If the expansion module is not aterminating device on the bus, set the EOLswitch to Off.

When a expansion module is connected topower with its EOL switch set to ON, theamber EOL LED on the expansion modulecover is lit.

Commissioning the ExpansionModules

You commission expansion modules with the Controller Configuration Tool (CCT) software, either via a Zigbee wireless dongle, through MAP 4.2+/BACnet Router (Mobile Access Portal (MAP) Gateway at version 4.2 or above), or in BACnet™ router mode when connected to an SNC, SNE, NAE or NCE. Refer to the Controller Tool Help (LIT-12011147) for detailed information on commissionings.

Firmware Package FileThe 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 IOMto the latest firmware release available for that expansion module.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).
