THE I-PONI

The INCOM Product Operated Network Interface(I-PONI) communicates between a computer control sta-tion and PowerNet or INCOM™ compatible products in aMaster/Slave format over a twisted-pair network. TheI-PONI uses power from the product to which it isattached and needs no other source of power. The I-PONIoperates over a temperature range of -20°C to 70°C.

PONI COMPATIBILITY

The following table shows the PowerNet and INCOMcompatible products and which PONI to use when placedinto a twisted-pair network.

The function selector switch is located on the front of theI-PONI (see Figure 1). The switch enables the user toselect the PowerNet baud rate between one of twooptions:

1) 1200 baud = SWITCH UP2) 9600 baud = SWITCH DOWN

NOTE: All products on the PowerNet network mustbe set at the same baud rate. Exception: Subnetworks may operate at a different baud rate thanthe main network (see Figure 7).

Each I-PONI has three hexadecimal (digits 0 through 9plus A through F) selector switches (address switches)that must be used to assign a unique address to eachproduct in the INCOM network (see Figure 1). A light emit-ting diode (LED), located to the left of the three addressswitches, flashes while the I-PONI is transmitting informa-tion into the INCOM network. The LED does not lightwhile the I-PONI is receiving messages (see Figure 1).

There are other versions of the PONI available such asthe RS 232 PONI and the PONI Modem, which do notcommunicate directly on the twisted-pair network.

INSTALLATION

The I-PONI is designed to be installed, operated, andmaintained by adequately trained people. These instruc-tions do not cover all details, variations, or combinationsof the equipment, its storage, delivery, installation, check-out, safe operation, or maintenance. The installer mustcomply with the National Electric Code and local codes

or regulations, as well as safety practices, for this class ofequipment. Please refer to the IMPACC Systems Com-munication manual (I.L. 17384) and the IMPACC WiringSpecification (T.D. 17513) for more detailed information.

NOTE: De-energize the device to which the I-PONIwill be attached or wired — otherwise miss-operationor damage to equipment could occur.

1. Make sure mounting screws for the I-PONI havebeen included.

Item Qty#8-32 X 1-1/8�Screw 2

2. Set the baud rate to 1200 bps if all of the products onPowerNet network are set for 1200 bps, 9600 bps ifall of the products on the PowerNet network are setfor 9600 bps. Note: Main networks and sub networkscan be set at different baud rates (see Figure 7).

3. Be sure to check the instruction leaflet mountinginstructions for each I-PONI compatible slave device.The following illustrates common examples of mount-ing instructions. In all cases the I-PONI is to bemounted in a horizontal manner.

3a) Mounting to MP 3000Disconnect power to the IQ 1000. Mount bracketusing the hardware indicated (see Figure 2). Mountthe I-PONI to the bracket (Part Number 7066C18H01) with LED and address switches on top and rib-bon cable on the right. Insert the nine-pin connectorattached to the I-PONI’s ribbon cable into the match-ing receptacle on the MP 3000 (see Figure 3). Withthe plug lock assembly in position, tighten the lockassembly screws. Wire into network with twisted pair.Repower device.

3b) Mounting to IQ Data Plus/IQ Data Plus Il/IQAnalyzer/IQDP4000 (without power module)Disconnect power to the IQ Data Plus. Mount I-PONIon the back of the IQ Data Plus using hardware indi-cated, with the LED and address switches on top andthe ribbon cable on the right (see Figure 4). Connectthe ribbon cable from the I-PONI to the receptacle ofthe IQ Data Plus and screw the plug lock assemblytight (see Figure 3). Repower device.

3c) Mounting to IQ Data Plus/IQ Data Plus II IQAnalyzer/IQDP4000 (with power module)

Disconnect power to the IQ Data Plus, IQ Analyzer,IQ DP4000. Mount the I-PONI to the threaded headstacking screws of the power module with the screwsincluded with the I-PONI (see Figure 5). Mount theI-PONI with the LED and address switches on topand the ribbon cable on the right. Connect the ribboncable from the I-PONI to the receptacle of the IQData Plus and screw the plug lock assembly tight(see Figure 3). Repower device.

4. Set the address selector switches (see Figure 6a).Each I-PONI installed in any one network must havea unique address. The three hexadecimal selectorswitches offer 4094 different addresses (16×16×16),ranging from 001 to FFE. A2 is the most significant

and AO is the least significant Hex address digit.Records of addresses should be maintained in termsof the hexadecimal number along with the connectedproduct and the baud rate of the I-PONI.

The PowerNet Network reads the address settings inhexidecimal notation as shown above (Figure 6a). There-fore the address can be read directly off of the I-PONIdials from left to right.

Some third party integrators may need to have the prod-uct address converted to decimal for their systems. Theabove example shows how to accomplish this if neces-sary (see Figure 6b).

NETWORKING

Master Device

The control station for the PowerNet network must be aunit such as a PC or PLC that will accept the PowerNetserial network signals. A MINTII may be used to convertPowerNet signals to the RS 232 format for transmissionto the master device.

Slave Device

An I-PONI may be used with PowerNet products or anyproduct that is designed to operate with the INCOM net-work format, and that has the standard INCOM 9-pin D-subminiature connector. (See table one forcompatibility)

SIMPLIFIED WIRING RULES

The following simplified rules apply given a system con-sists of a single daisy chained main cable link betweenmaster and slave devices and all slave nodes areI-PONIs (see Figure 7). For more complex considerationsincluding star configurations or systems containing oldand new PONIs please refer to the IMPACC Wiring Spec-ification or the PMAS for wiring instructions and systemcapacity considerations. The IMPACC Wiring Spec isT.D. 17513 or FRED (Fax Retrieval of Engineering Docu-ments) Document 17513.

• The maximum system capacity is 10,000 feet of com-munications cable and 1000 slave devices.

• Main cable link must be terminated at each end by a1/4 watt, 100 ohm, carbon resistor.

• Non terminated taps, up to 200 feet in length, off themain link are permitted, but add to the total cablelength.

• Terminals 1 & 2 on the Network Connection (see Fig-ure 1 & 8) are for the twisted pair connection, whileterminal 3 is for the shield. (Note: It is recommendedthat ferrules be used to dress the ends of the cableleads to minimize frayed connections.)

• Make sure that there is a twisted wire pair presentthat is intended for PowerNet network use. Usetwisted pair wire (IMPCABLE, Belden 9463, or equiv-alent) to connect each I-PONI to the PowerNet net-work, daisy-chain style (see Figure 2). Attach thetwisted pairs to the three-pole plug located on theside of the I-PONI assembly. The polarity of thetwisted pair is not important.

OPERATION CHECK

After the PowerNet system has been installed, check theoperation of each I-PONI by applying power to the parentunit and issuing an PowerNet command. Using the appli-cation software running on the PC to issue the com-mands, do this for each I-PONI using its selectedaddress. The product responds by flashing the LED (OFFto receive, ON while transmitting, OFF to receive). Theflashing LED indicates that the product is functioning cor-rectly.

TROUBLE SHOOTING

In the unlikely event the LED remains OFF, try the follow-ing items:

1. Check the baud rate selection on the I-PONI. Makesure that it is communicating at the same rate as therest of the network devices.

2. Check the function of the device the I-PONI ismounted on; is it connected, powered, and showingcorrect readings on the faceplate?

3. Check that the application software is installed andfunctioning correctly.

4. Remove and replace the I-PONI’s ribbon cable-fromthe product.

5. Check the PowerNet network wiring for loose con-nections, shorted wires, etc.

6. Apply Dr. IMPACC software (style number 8163A43G01). This software is provided with eachCONI Card or can be downloaded by accessing thePMAS BBS (Bulletin Board System).

7. If suggestions 1-6 do not remedy the problem, theI-PONI may need to be replaced.

The user should not attempt to service this equipment.The Phoenix Connector (see Figure 1) is the onlyreplacement part available for the I-PONI (C-H PartNumber 5281C91H49 - Phoenix Contact # MSTB 2.5/3-ST-5.08)

Please contact your local Eaton representativeor Eaton Support for service information or additionalquestions.
