PT-Link II BACnet® Technical Guide

General Information

The OE368-23B-BACNET2, PT -Link II BACnet® provides bi-directional communication between your BACnet® MS/TP protocol network and up to four* of any of the following types of Orion controllers—RNE, VCB-X, VCM-X, SA, VCM, MUA II, or VAV/CAV:

RNE Controller (SS1045) VCB-X Controller (SS1051) VCM-X Controller (SS1026, SS1030, SS1032, SS1033,

SS1034, Y200920) SA Controller (Y200921)

VCM Controller (SS1016, Y200409, Y200616, Y200822) **MUA II Controller (Y200405); VAV/CAV Controller

(Y200301)

To determine what controller you have, you must look at the label located on the controller EPROM. If the controller label does not match any of the SS or Y numbers listed above, your controller will not work with the PT-Link II BACnet®.

*NOTE: The PT-Link II BACnet® device can be used to con-

nect to four Orion controllers. If more than four Orion controllers are present in a system, you will need one or more additional PT-Link II BACnet® devices for integration with a BACnet® protocol network.

**NOTE: Documentation is available for MUA II/VAV/CA V on

our Orion Controls website: www.orioncontrols.com/ literature-new.html

PT-Link II Ethernet Connection

PT-Link II Hardware Connection

You have two options for connecting the PT-Link II to your PC via Ethernet:

1.) You may connect the PT-Link II directly to your PC by using a crossover cable (by others) as shown. See Figure 3 for details.

2.) You can also connect both your PC and the PT -Link II to an Ethernet Hub with standard CAT5 cables. See Figure 4 for details.

Desktop Or Laptop PC

Connect Ethernet Crossover Cable Directly To PC Ethernet Card Port

Locate a CAT5 cable and plug one end into your computer’s Ethernet port (use a crossover cable if connecting directly to the PT-Link II). If connecting directly, plug the other end of the Cable into the Ethernet port on the PT -Link II. If connecting through an Ethernet Hub, plug the other end of the PC cable into the hub, and use a second CAT5 cable to connect the PT-Link II to the hub as well.

Power up the PT -Link II by plugging in the power cable. The PT-Link II may take up to three minutes to power up completely. Once the PT-Link II is powered up, depending on which type of BACnet module you have, you should notice that the green GP105 LED remains on or the RUN LED is blinking continuously on the ProtoCessor Board. See Figure 25 and 27 on pages 16 & 17 for a diagram showing the location of the ProtoCessor RUN or GP105 LED.

Conﬁ guring the PT-Link DIP Switches

PT-Link DIP Switch Conﬁ guration

If the BACnet address doesn’t need to be any higher than 255, then follow these directions to use the DIP Switch settings to conﬁ gure your PT-Link II. The DIP Switches are shown in Figure 9.

The conﬁ g.csv ﬁ le’s ‘Server_DIP’ parameter will default to ‘Enabled’ which will allow the System_Node_ID (BACnet MAC Address) and Node_ID (Device Instance) to be set using the DIP Switches on the module. See Figure 17 on page 12. With this capability, RUINET is not needed for the initial conﬁ guration. Set the DIP Switches, power up the PT-Link II, wait 4 minutes, and your PT-Link II BACnet is ready.

FFP-485

DIP Switch Bank A

The DIP Switches allow you to set the Baud Rate, Node-ID (Device Instance), and MAC address on the Field RS-485 protocol as well as to automatically download conﬁ guration ﬁ les for certain protocols.

The DIP Switches are designated by Bank A & B. Bank A is used to select both the MAC Address and Device Instance – if using the DIP switches these will always be the same. The maximum legal value is

255. See Appendix C for each possible combination for the addresses.

Bank B is used to set the Server Baud rate. For setting serial ﬁ eld pro- tocol baud rate, the DIP Switches B1 – B4 can be set for the following speeds. See Table 2 for Server Baud rate settings.

NOTE: Y ou must cycle power after making changes to the DIP

Switch Settings for the settings to take effect.

Running RUINET

Connecting To The PT-Link II

NOTE: The preferred method of conﬁ guration is to use the DIP

Switches on the Protocessor board unless your address setting needs to be greater than 255.

1.) In order to communicate and program the PT-Link II you will need to install RUINET software on your computer. If you do not have the software, it is available for downloading at www.orioncontrols.com/software-new.html under PT-Link II Software

WARNING: Make sure to load RUINET onto your hard drive

and run the program from your hard drive. DO NOT under any circumstances run RUINET from your cd drive.

2.) If RUINET is in the desktop directory (if it isn’t, locate its directory), double-click on RUINET, and the RUINET program should run. Initially, you might see the screen below (Figure 10).

Figure 10: Update FieldServer Date and Time

3.) Type <Y> to sync the Date/Time on your PC. The following screen will appear (Figure 11). Press any key to continue.

4.) The following screen may appear (Figure 12). Type <I> for Specify IP Address and the message “Enter IP Address of the Field Server to Connect to” will appear on the screen.

Figure 12: RUINET PT-Link Specify IP Address

5.) Type the IP Address of <192.168.1.24> and press <Enter>.

6.) If you have only one PT-Link connected to the network, then RUINET will automatically connect to that particular PT-Link; otherwise, a menu will appear to allow the selection of the desired PT-Link.

NOTE: If RUINET is unable to establish a connection, there

are a few simple procedures you can perform to try to determine the problem. T o verify your network cables, observe the green LED displayed directly above and to the right of the Ethernet port. This LED should be on if the 10 BaseT cable is good. Secondly, observe the red LED displayed directly above and to the left of the Ethernet port. This LED should be solid while RUINET is running. If the LEDs are lit as expected, and RUINET still does not receive replies, then the netmask is probably incorrect. If this does not help, then your Ethernet setup on your PC is possibly not compatible. Ensure that you have an Ethernet adapter installed in your software conﬁ guration and that it is conﬁ gured to run the TCP/IP protocol. If you are still unable to connect, please contact W attMaster Controls.

Addressing WattMaster Devices in a BACnet

Each PT-Link II BACnet® generates only one BACnet® device regardless of the number of WattMaster controls connected to it. This device will have all the properties of all the WattMaster controls connected. The instance of the device is equal to the unit address. The properties of each control can be differentiated by an offset of 500.

Examples:

1.) Properties of the controller address as 1 will range from 0 to 499.

2.) Properties of the controller address as 2 will range from 500 to 999.

3.) Properties of the controller address as 3 will range from 1000 to 1499.

To search for the instance of a specific property, follow the next formula:

Property Instance = ((Controller Address – 1) * 500) + Instance Number from table.

Network.

Example:

1.) The PT-Link II BACnet® has a Node ID equal to ﬁ ve.

2.) Two VCM controllers connected and addressed to one and four.

3.) Searching for the Outdoor Temperature of each controller.

4.) Instance of the Outdoor Temperature in the VCM table equal to AI: 54.

5.) Client will only see Device 5.

6.) Under Device 5 it will see AI: 54 for the Outdoor Temperature of the unit addressed as 1 and AI: 1554 for the Outdoor Temperature of the unit addressed as 4.

NOTE: To simplify the calculation, we recommend that the

WattMaster controllers be addressed in sequential order from one to the last controller without any unused address(es) in between.

Troubleshooting the PT-Link II Controller

PT-Link II Board LEDs

The PT-Link II BACnet® is equipped with LEDs that can be used for troubleshooting. There are eight LEDs on the PT -Link board. See Figure 24 for the locations of the LEDs on the PT -Link board. The LED descriptions and functions are listed in the following paragraphs.

POWER LED

When the PT-Link II BACnet® is powered up, the “POWER” LED should light up and stay on continuously. If it does not light up, check to be sure that you have 24 VAC connected to the board, that the wiring connections are tight, and that they are wired for correct polarity. The 24 V AC power must be connected so that all ground wires remain common. If after making all these checks the “POWER” LED still does not light up, please contact WattMaster Controls Technical Support at our Toll Free number—866-918-1100—for assistance.

LOOP LED

When power is applied to the PT-Link II BACnet®, the “LOOP” LED will also light up. The LED should ﬂ icker rapidly, indicating that the PT-Link is trying to communicate with the controllers on the loop. A “ﬂ icker” is deﬁ ned as a brief moment when the LED turns off and back on. If the “LOOP” LED does not operate as indicated above, ﬁ rst power down the unit and then reapply power. If this does not work, please contact WattMaster Controls Technical Support at our Toll Free number—866-918-1100—for assistance.

PT-Link II BACnet® Technical Guide

LED 1

When power is ﬁ rst applied, “LED 1” will be off temporarily and then will blink one time for each controller it is communicating with. For example, if you have 4 controllers on the loop connected to the PT -Link, “LED 1” will blink 4 times. If the amount of blinks does not match the number of controllers connected to the loop, it indicates there is a communications problem. The best way to ﬁ nd out which board is not com- municating is to go to each controller and look at its “COMM” LED. The “COMM” LED should be solid and will ﬂ icker occasionally indicating communication with the PT-Link II BACnet®. If the “COMM” LED does not ﬂ icker, there is no communication with that controller.

LED 2

When power is ﬁ rst applied, “LED 2” will be off temporarily and then will blink slowly indicating that the PT -Link baseboard is communicating with the ProtoCessor Module. If “LED 2” does not blink, check that the ProtoCessor Module is installed correctly on the PT -Link baseboard and that the “PWR” LED is lit up on the ProtoCessor Module.

PROTO LED

When the PT-Link II is ﬁ rst powered up, the “PROTO” LED should blink rapidly and may appear to be on solid. This LED veriﬁ es com- munication with the board and the ProtoCessor. If the LED doesn’t light up, check that the ProtoCessor is installed correctly and ﬁ rmly connected to the Base Board. The “PWR” LED should also be lit on the ProtoCessor Module.

Figure 24: PT-Link II BACNET® LED Locations

WATCH DOG LED

The “W-DOG” LED is used for troubleshooting by W attMaster Controls Technical Support. The “W-DOG” LED should always be on solid.

HEARTBEAT LED

The “H-BEAT” LED blinks to show the PT-Link II board software is running. If the LED doesn’t light up, and all other checks have been made, please contact W attMaster Controls T echnical Support at our T oll Free number—866-918-1100—for assistance.

TIMER LED

The “TIMER” LED is used for troubleshooting by W attMaster Controls Technical Support. The “TIMER” LED should always be blinking steadily.

ProtoCessor Module LEDs

Refer to Figure 25 for LED locations. NOTE: If your BACnet module does not have DIP switches, refer to Figure 27 on page 17.

PWR LED

When the PT -Link II is ﬁ rst powered up, the “PWR” green LED should light up and stay on continuously. If the LED doesn’t light up, check that the ProtoCessor is installed correctly and ﬁ rmly connected to the Base Board.

UNUSED LEDs

15 seconds after powering up, the 4 unused LEDs will turn on solid for 5 seconds, then turn off.

RX & TX LEDs

During normal operation, the “RX” LED will ﬂ ash when a message is received on the ﬁ eld port of the ProtoCessor and the “TX” LED will ﬂ ash when a message is sent on the ﬁ eld port of the ProtoCessor The “TX” and “RX” LEDs work together to indicate that communication is being established with the desired protocol network. If both LEDs are blinking, then communication is working properly. If not, check the protocol network wiring and the baud rate in the conﬁ guration ﬁ le.

RUN LED

The “RUN” LED will ﬂ ash 20 seconds after power up, signifying normal operation. The Protocessor will be able to access RUINET once this LED starts ﬂ ashing. During the ﬁ rst 20 seconds, the LED should be off.

CONFIG ERR LED

The “CONFIG ERR” LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady amber light will indicate a conﬁ guration error exists in the active conﬁ guration. See the Error Screen in the Remote User Interface for a description of the conﬁ guration error.

NODE OFFLINE LED

The “NODE OFFLINE” LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. If the Node Ofﬂ ine LED stays on solid, a node ofﬂ ine condition has occurred.

NOTE: If all of these tests are made and the controller still doesn’t

operate, please contact W attMaster Controls T echnical Support at our T oll Free number—866-918-1100—for assistance.

–

SYS ERR LED

The “SYS ERR” LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red light will indicate there is a system error on the ProtoCessor. If this occurs, immediately report the related “system error” shown in the error screen of the Remote User Interface to FieldServer Technologies for evaluation.

COMM ERR

The “COMM ERR” LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red light will indicate a communications problem if there is a conﬁ gured node connected to the ProtoCessor that is ofﬂ ine. To establish the cause of the error, go to the error screen of the Remote User Interface interface.

GPI05 LED

The “GPI05” LED will light up when the Base Board and the ProtoCessor Module have established communications. This can take up to 3 minutes depending on the number of units connected to the PT -Link II. If it fails to light up after 3 minutes, check that the ProtoCessor is installed correctly and ﬁ rmly to the Base Board.

LB LED

Once the unit is powered up, the “LB” LED must be blinking constantly. If this LED is constantly on or off, the Module is not working properly and needs to be replaced.

PT-Link II BACnet® Technical Guide

LA LED

Once the unit is powered up, the “LA” LED must be blinking constantly. If this LED is constantly on or off, the Module is not working properly and needs to be replaced.

TX & RX LEDs

Troubleshooting the PT-Link II Controller

Using RUINET

Before continuing with the troubleshooting, make sure the PT-Link is connected correctly and the RUINET software is installed, running, and functioning correctly.

Verifying Proper Communications

From the RUINET Main Screen, press <O> to go the Connection Overview Screen. This screen supplies information on communication

between the PT-Link and remote devices. A number of aspect screens are available, and some of the aspect screens have more than one page. Use the space bar to toggle between aspects and use the <PgUp> and

<PgDn> keys to toggle between pages of the same aspect. The Con-

nection Overview and Settings Aspect Screen is shown in Figure 28.

The main purpose in this screen is to verify that messages and characters are being transmitted and received. In addition, it shows the number of communication errors. If the PT-Link connection “03” is the protocol connection, verify that is communicating appropriately. If it is not, check that the PT -Link LEDs are working properly , the unit is wired correctly , and the PT-Link is conﬁ gured correctly (Baud Rate, Unit Address & MAC Address). If the number of errors is constantly increasing, move to the Error Screen by pressing the <Space Bar> 3 times to ﬁ nd out the cause of the errors. Use the <PgUp> and <PgDn> keys to toggle between pages of the Error Screen.

Figure 28: Connection Overview Screen

Verifying Proper Values

To verify that the correct values for each unit are being communicated to the PT-Link, move to the Data Array Overview Screen. To get to the screen, press <A> from the RUINET Main Menu. See Figure 29 for screen details.

In the Data Array Overview Screen (Figure 29) you will be able to see the data arrays of all the units connected to the PT-Link denoted by an array name “DA_XXX_IY”—Y being the address of the unit minus one. The Address of the unit is determined by a set of DIP switches. To view the values being communicated from a speciﬁ c unit, move to the Data Array Detail Screen (Figure 30) of the unit by entering the number under which it is listed. For example, for the unit listed in the third position, enter <03>.

To understand what each value means, look at the Data Array Tables for the desired unit type, VCM-X, SA, or VCM. You can change the writable values from this screen by using the modify command. T o use the modify command, press <M> from the Data Array Detail Screen and then enter the Offset you want to change followed by a space and the new value.

Example: T o change the Cooling Supply Setpoint to 60 in the VCM, press

<M>, enter <58 60>, and then press <Enter>. This could be useful to

prove that the unit can take and keep the setpoints properly.
