Installation/Reference Guide Operation

Operation

The I/NET® Communications Interface or ICI is an I/NET hardware component. The ICI acts as a bridge between the controller LAN and another on-line data communica-tion system/network. The ICI lets you transfer analog or discrete point data, and trans-lates between the two systems.

The ICI is addressed, programmed, and controlled just like the other controllers. It uses the same data point types and provides a database for the parameters and values associ-ated with the data points. Refer to the section concerning point definition and addressing in I/NET 2000 Operator Guide, for details on defining and entering data points.

The Model 7797 ICI hardware can be defined using downloadable software to define hardware functionality. In this way the 7797 can support multiple third-party platforms. When the proper software is downloaded into the 7797, its model number changes to reflect its new functionality (e.g. 779704 indicates a 7797 supporting McQuay Interna-tional DDC control units).

In partnership with McQuay International’s MicroTech Open Protocol, the ICI (779704) interfaces through the factory-mounted MicroTech DDC controllers, supporting the types of McQuay and AAF equipment listed below:

✦ Centrifugal MicroTech devices

✦ Absorption MicroTech devices

✦ Reciprocating MicroTech devices

✦ Applied Rooftop Units

✦ Unit Ventilators

✦ Water Source Heat Pumps

Note: You must obtain a site licence from the McQuay representative in order to perform a site commissioning.

An ICI is required for each directly connected MicroTech controller. Alternatively, an ICI may connect to a MicroTech OPM panel which is connected to two or more MicroTech unit controllers. Each MicroTech controller is shipped with a unique job site password of eight ASCII characters (0 through F), and must be obtained from the McQuay repre-sentative during installation.

Installation Installation/Reference Guide

Installation

You must have I/NET 2000 installed before installing the ICI Editor. You must install the ICI Editor and a Model 779704 ICI before you can communicate between I/NET and the McQuay. Use the following procedures to install the ICI Editor and the 779704. After installation is complete you may configure the software and the controller for operation.

Installing and Configuring the 779704 ICI Controller

The 7797 ICI is software configurable for several types of controllers, although this docu-ment is concerned only with the McQuay International. Configure the ICI type using the I/NET system host software. This lets you set the type of controller that the ICI will connect to and download the binary file to the ICI, defining its operation. Refer to Table 1 for ICI controller type number of the McQuay International. The procedure is provided below.

Note: This document supports only the McQuay controller type.

Install the 7797 in the following order.

Note: As with other controllers, you must enter the station address into the ICI using a hand-held console. Please refer to the installation guide accompanying your ICI unit for the correct procedure.

1. Using an HC7410 hand-held console, enter the DCU station addresses for the 7797.

Note: All I/NET controllers must be assigned a station address. The station address is any two-digit number between 00 and 63 you have not already assigned to another controller. You must assign the station address before you begin adding points to the database because part of the point address is the station address. The station address is always the second two digits of the eight-digit point address. Refer to TCON122, Series 7797 I/NET Communica-tions Interface Installation Guide, for procedures.

2. Configure the ICI as a 779701, or other desired Tap emulation device using an HC7410 hand-held console.

Installation/Reference Guide Installation

Note: Before downloading the software to the 7797, ensure that it is configured for any Tap func-tions it may perform using the HC7410 Code 91 function, and is defined using the Code 90 function. Refer to TCON122, Series 7797 I/NET Communications Interface Installation Guide.

3. Configure the I/NET host to connect to the 7797, and configure the 779704 (refer to “Configuring the I/NET Host” on page 3).

4. Enter the Resident I/O Points editor and enter the points for the 7797.

Note: While you can enter all I/NET resident I/O points from the ICI editor, the settings and parameters of those points in the I/NET host can only be set through the I/NET 2000 Resi-dent I/O Point editor.

5. Using the standalone ICI Point Mapping editor, map the I/NET 2000 points to the McQuay devices (refer to “ICI Editor Configuration and Data Point Population” on page 6).

Configuring the I/NET HostYou must configure the 7797 on the I/NET system before you can add points to the system for the McQuay.

Configuring the 779704 on I/NET

Use the following procedure to configure the 779704 through the I/NET host.

1. Copy the new 779704.bin file from the floppy disk to your DATA directory.

Caution: Failure to use the new 779704.bin file will cause the ICI Editor to malfunction.

2. Select Start Programs INET 2000 INET 2000 and login to the I/NET system.

Note: The actual folder name may be different, depending on the selection you made when installing I/NET 2000.

3. Connect through the system until you are connected to a 7797 ICI.

4. From the menu bar select Edit Controller Configuration.

5. In the DCU Configuration editor set the parameters as you would normally set any controller (see Figure 1).

6. In the DCU Configuration editor select 04: McQuay to set the ICI controller type.

7. Click the OK button to accept the changes and return to the Edit menu.

8. Select Edit Host Computer Network Configuration, the Link Summary Configuration editor and penetrate to the 779704 to the Station Summary.

9. Save the configuration.

779704 ICI 3


10. Select Edit Host Computer Software Restore, or click the Software Restore tool ( ) on the Controller toolbar. The system displays the Software Restore screen (see Figure 2).

Figure 1. Configuration/Status Data Entry Screen

Figure 2. Software Restore Screen

4 779704 ICI


This screen displays all the Taps and controllers that you previously defined as downloadable in the Network Definition portion of the Network Configuration editor. Refer to the section on setup and network configuration in I/NET 2000 System Operator Guide, for more information.

11. Use the Software button and the Database button to control which column will be marked with a Y during the station selection process in the next step.

12. Choose stations from the list. You can individually select or deselect stations, or you can use All Yes and All No to speed the selection process. Stations that you select to receive the software restore will display a Y in the Software and/or the Database column of the list.

13. If necessary, define the drive and path to the directory that contains the software to be restored in the Software Directory field. By default, I/NET restores software from the Data directory defined in the Configure program.

14. When you have selected the necessary stations, select Download to begin the soft-ware restore process.

The system begins downloading binary files to stations that have a Y in the Soft-ware column. Database Save (.SAV) files are downloaded to stations that have a Y in the Database column.

15. Select Close to leave the Software Restore screen. If the software restore is still running, it will continue until completed.

For each device selected, the system downloads any selected controller/Tap software first, and then the controller database. The download of both types of information is completed before the system moves on to the next device in the list. If a download was successful, the Y in the Software or Database column changes to a –, meaning you have just completed the download and there is nothing more to download. If you try to down-load a controller database and the Y does not change to a – for that controller, this means a save file does not exist (the system could not find a database to download) or a commu-nication failure has occurred.

The 779704 ICI can address one station with a point capacity or 320 inputs, and 320 outputs.

Populating the Database

After you have configured the 7797 within the I/NET system it is recommended that you populate the database with resident I/O points, set the station parameters (including Control and State Descriptions to match those expected at the McQuay OPM) and set the other parameters and settings required to identify and control the points. Refer to the section concerning resident I/O points in I/NET 2000 System Operator Guide, for details.

1. Enter the Resident I/O Points editor and enter the points for the 7797.

2. Enter the State Descriptions for the points.

3. Enter all other parameters and settings.

4. Save the configuration and database.

Configuring the ICITo configure the ICI to communicate with the McQuay you must set several configura-tion parameters.

The Inter-message delay is the time that the ICI delays before sending another request. This delay ensures that the receiving device has enough time to prepare and transmit the response. The delay range is zero to 2.55 seconds in 10 milli-second increments.

The Response timeout is the time that the ICI waits for a response after sending a request. This is used to limit the amount of time that the ICI will wait before it logs the request as not being processed and moves on to the next request. The delay range is zero to 2.55 seconds in 10 milli-second increments.

Note: The system automatically enters default settings in the editor for inter-message delay and response timeout. Other values than the ones shown below may appear if a previous config-uration was uses. Enter the recommended settings shown below. You may alter the settings later if you encounter any deficiencies in operation traceable to these parameters.

From the menu select Edit Configuration. The editor in Figure 4 displays.

1. ICI Port Status should be set as Enabled.

2. Set the Baud Rate to 9,600. The available range is 300 to 19200.

3. Set the Data Bits to 8. The available range is 7 or 8.

4. Set the Stop Bits to 1. The available range is 1 or 2.

5. Set the Parity to None. The available range is Odd, None, or Even.

6. Set the Inter-message delay (sec) to 1. The available range is 0 to 2.55 seconds.

7. Set the Response timeout (sec) to 1. The available range is 0 to 2.55 seconds.

8. Enter the Password. The password will consist of eight ASCII characters, 0 – F, and must be obtained from the McQuay representative during installation.

9. Click OK to accept the parameters and return to the ICI Editor.

2. Click Yes to delete the point, or No to return to the ICI editor without deleting the point.

ICI Point MappingThe ICI supports all standard I/NET input and output points. The point type and number of points depends upon the connecting controller. Refer to the section on point definition and addressing in I/NET 2000 Operator Guide, for a detailed description of each point type.

As you add I/O points, refer to the accompanying third-party documentation for the MicroTech device to determine addresses. Read Only information from the MicroTech device requires an input address), Read/Write information requires an output address). Determine whether the point type is digital or analog by the type of information the point will read. Some values from the MicroTech device, notably temperatures, pres-sures, and compressor operating hours and starts will require two address and two points in the ICI.

Note: You must use a third point after a calculation is made to present the value.

The McQuay uses:

✦ Master to indicate the MicroTech device,

✦ Slave to identify Open Protocol Master address,

✦ and Memory Address to identify the virtual memory address of the point.

In the screen example in Figure 7, the mapped point in the ICI at address 00050001 is an AI point. It refers to the McQuay point at with a MicroTech device ID of 0x0001 (hexa-decimal address), an OPM address of 0x0000, and a virtual memory address of 0x0461.

Figure 6. ICI Editor Delete Dialog Box

779704 ICI 9


Note: All mapped resident points are external points. You may define as internal or indirect any points that are not mapped across from the McQuay MicroTech device.

To map the McQuay points to the ICI on the I/NET system, select Edit ICI point map Modify from the Edit menu. The editor shown in Figure 7 displays.

Any point addresses that you previously entered in the I/NET Resident I/O Points editor will be recognized by the ICI Editor. The point’s name, scan time, and point type will be automatically entered if you entered them in the I/NET Resident I/O Points editor. Any I/NET point address can be mapped to any available ICI point values. Any point address may be used as long as the point type (i.e. AO, AI, DI, DO, etc.) matches the available ICI point types.
