CCN DATAPORT

1

The CCN DATAPORT made by Carrier Corporation is an interfacethrough which certain data from one or more devices connected to aCCN Communications Bus can be transmitted to a non-CCN device.It is for use in applications that require the transfer of status infor-mation from a CCN controller to a device, not manufactured byCarrier, that cannot be connected to a CCN Communications Bus.A DATAPORT is a read-only device. It does not convey data fromthe off-network, non-CCN device onto the CCN bus.

This manual describes the purpose, function, and operation of theDATAPORT. It includes descriptions of the DATAPORT’s physi-cal characteristics, the screen displays by which an operator interactswith the DATAPORT from a Building Supervisor or CCN ServiceTool, and the command and error codes by which an off-networkinteracts with the DATAPORT.

The data that can be transmitted through a DATAPORT is mainte-nance and operating information that is contained in a CCNcontroller’s Point Screen. The DATAPORT reads the data from thecontroller, converts it into ASCII characters, and transmits it to theoff-network device. The off-network device receiving the data maybe either a non-Carrier controller that employs the data as input to acontrol routine, or a personal computer.

The CCN controllers from which the DATAPORT can transmit datahave to be specified in the DATAPORT’s configuration table, whichis accessible by means of a Building Supervisor or CCN ServiceTool. The actual transmission of data is controlled by commandssent form the off-network device that is to receive the data. ABuilding Supervisor or CCN Service Tool can also display aDATAPORT maintenance screen that shows information about howthe DATAPORT is operating.

The controllers from which the DATAPORT can transmit PointScreen data include PICs and CIO Module-based devices such as theCPOC and the 32MP Gateway. The DATAPORT cannot transmitdata from a FID.

GeneralInformation

Introduction

2

This manual is intended for use by an operator who has access toboth the off-network device that is to receive data from theDATAPORT and the CCN system in which the DATAPORT isinstalled. It is divided into four sections:

• Introduction contains brief descriptions of the DATAPORT andthe Manual.

• Operating Characteristics describes the CIO Module in whichthe DATAPORT runs and the functions that the DATAPORTperforms.

• Configuration and Maintenance Screens describes the deci-sions that appear on the screens an operator can access from aCCN Building Supervisor or Service Tool to configure aDATAPORT or monitor its operation.

• Off-Network Control describes the commands that be sent fromthe off-network device to the DATAPORT to control its opera-tion and the error messages that the DATAPORT can send to theoff-network device when a command cannot be carried out.

About This Manual

3

A DATAPORT consists of a CIO Module equipped with specializedsoftware to perform the tasks required of it. Those tasks consist ofrequesting Point Screen data from the appropriate CCN controllerson the CCN Communications Bus, translating the data into ASCIIcharacters, and outputting those characters through the CIOModule’s RS-232 COMM2 connector.

The CIO Module is shown in Figure 1. When used as aDATAPORT, the CIO Module employs the 4-pin, Phoenix-typeconnector labeled COMM1 and the 25-pin, D-shell connectorlabeled COMM2.

COMM1 is the DATAPORT’s connection to a CCN Communica-tion Bus. The bus, which uses RS-485 signaling, may operate at1200, 2400, 4800, or 9600 bits per second. It typically operates at9600. A DATAPORT may reside on any CCN CommunicationsBus, 0-239, and may be assigned any system element number, 1-239. The DATAPORT’s default address is bus 0, system elementnumber 110. The CCN Network Configuration Tool (NCT) may beused to change the DATAPORT’s bus and element numbers and theoperating rate for COMM1.

COMM2 is the DATAPORT’s connection to the off-network devicethat is to receive the ASCII characters. It accepts and transmits RS-232 signals at a rate of 1200, 2400, 4800, or 9600 bits per second.The operating rate of COMM2 is set from a Building supervisor or aService Tool by means of a configuration decision in theDATAPORT. The DATAPORT compensates for differencesbetween the operating rates of COMM1 and COMM2.

The cable between the off-network device and COMM2 of theDATAPORT can be up to 50 feet in length.

Only four pins of the COMM2 connector are used in theDATAPORT’s RS-232 communications:

• Pin 1 - protective ground• Pin 2 - transmit data• Pin 3 - receive data• Pin 7 - signal ground

The DATAPORT employs software control to regulate the transmis-sion of data through COMM2, so RS-232 control signals are notrequired on the other pins of the connector.

5

A DATAPORT can be configured with the addresses of up to 15CCN controllers. The user configures the DATAPORT by enteringeach controller’s bus number and system element number in theDATAPORT’s configuration table.

The DATAPORT maintains a database for its configured control-lers that contains the following information (static data) for eachpoint in each controller.

• Point name (up to eight alphanumeric characters)• Units ( a three-digit code that identifies the unit of measure)• Description (up to 24 alphanumeric characters)

There are three conditions that cause the DATAPORT to acquirenew static data for its database. First, two minutes after theDATAPORT is powered on, it will poll its configured devices forstatic data. Second, it will poll automatically when a changedconfiguration table is downloaded to it. Third, it will poll in re-sponse to a Read Configuration command from the off-networkdevice.

The DATAPORT database can contain entries for up to 900 points,which works out to 60 points in each of 15 controllers. If control-lers are configured that contain more than 60 points apiece, there isan effective reduction in the number of controllers that theDATAPORT can support.

For example, if controllers are configured that contain 100 pointsapiece, all 15 sets of bus and system element numbers may still beentered in the configuration table, but only the first nine controllerswill be accessible to a Send Controller Data command. If the off-network device were to command the DATAPORT to send datafrom any of the last six configured controllers, the DATAPORTwould respond with an error message of 4, which means DatabaseFull.

The CCN controllers are associated by the order in which they areconfigured with single letter ASCII command A through O (ineither upper or lower case). A is the Send Controller Data for

DATAPORTFunctions

6

Controller 1 command and O is the Send Controller Data for Con-troller 15 command. Each Send Controller Data command instructsthe DATAPORT to perform the following functions:

• read the dynamic data portion of a Point list display (value andstatus for each point) from the controller that corresponds to thecommand letter

• translate the data into ASCII characters• format the characters together with the appropriate static data

stored in the DATAPORT database• transmit the result through COMM2

When commanded to transmit a CCN controller’s point data, theDATAPORT first transmits an ASCII Form Feed character. Thenfor each point in the requested controller the DATAPORT transmitsa line of data in the following format:

Name Value Units Status Description (Carriage Return)

Single spaces are transmitted to separate Name, Value, Units,Status, and Description. A second Carriage Return is transmittedfollowing the last point in the controller. The Carriage Returncharacters transmitted by the DATAPORT do not provide line feed.

The point name consists of up to 8 alphanumeric characters. Thisname appears in the rightmost column on a Building SupervisorPoints Screen.

The point value may consist of up to ten characters. If the value isanalog, it is presented in the same format in which it would appearon a Building Supervisor screen, that is, with the same number ofdigits and decimal point placement. If an analog point value isoutside the range that can be represented by ten characters, theDATAPORT will transmit ten asterisks in place of the value. If thepoint value is discrete, it is presented as a 1 or a 0.

The units designator transmitted through the DATAPORT takes theform of a three digit number. Table 1 explains how the numberscorrespond to units of measure.

7

Status is also transmitted as a three digit number. Each statusnumber represents a unique combination of an error condition and aforce condition. Table 2 defines how to decode transmitted statusnumbers into error and force codes. Simply locate the displayedstatus number in the table. The table’s columns correspond to errorconditions and its rows correspond to force conditions. The twolists below the table describe the conditions.

The point description consists of up to 24 alphanumeric characters.Transmission of the description field can be suppressed by a com-mand from the off-network device.

Off-NetworkControlCommands

There are 22 commands that can be sent from the off-networkdevice to the DATAPORT. Each command may be sent in the formof one ASCII character or its hexadecimal numeric equivalent.

The 15 Send Controller Data commands, one for each controller thatcan be configured in the DATAPORT, are each represented by asingle ASCII letter. If a keyboard is used to input commands fromthe off-network device to the DATAPORT, the letter commandsmay be sent in either upper or lower case. ASCII code representsthe upper and lower case forms of a letter with different hexadeci-mal values. If commands are programmed into the off-networkdevice as hexadecimal values, the hexadecimal equivalent of eitherupper or lower case may be used.

The other seven commands are represented by ASCII control char-acters. One of those is the character generated by pressing akeyboard’s Escape (ESC) key. The remaining six are characters thatare generated by simultaneously pressing the keyboard’s Controlkey and a letter key. The hexadecimal equivalents of the Control/letter combinations are the same for both upper and lower caseletters.

In the list that appears on the next page, each DATAPORT com-mand is identified by name, by the key or combination of keys usedto input the command at a keyboard, and by the hexadecimalequivalent of the character.

22

Controller 1 = A (41H) or a (61H)Controller 2 = B (42H) or b (62H)Controller 3 = C (43H) or c (63H)Controller 4 = D (44H) or d (64H)Controller 5 = E (45H) or e (65H)Controller 6 = F (46H) or f (66H)Controller 7 = G (47H) or g (67H)Controller 8 = H (48H) or h (68H)Controller 9 = I (49H) or i (69H)Controller 10 = J (4AH) or j (6AH)Controller 11 = K (4BH) or k (6BH)Controller 12 = L (4CH) or l (6CH)Controller 13 = M (4DH) or m (6DH)Controller 14 = N (4EH) or n (6EH)Controller 15 = O (4FH) or o (6FH)

Each Send Controller Data command is a one-shotinstruction for the DATAPORT to get point data fromthe specified controller and transmit it to the off-networkdevice. Transmission of a controller’s point data maymade to pause and resume by an XOFF command and anXON command, or stopped completely by a Stop Send-ing command. If the DATAPORT receives a SendController Data command while it is already transmittingdata, it will immediately stop the transmission inprogress and respond to the newly received command.

Control/P or Control/p (10H)

This command instructs the DATAPORT to periodicallyupdate and transmit point data from the controller thatwas specified by the most recent Send Controller Datacommand. The Update Period configuration decisiondetermines how frequently the transmissions occur.Transmissions begun by this command may be made topause and resume by the XOFF and XON commands.Transmissions may be stopped completely by a StopSending command, after which the DATAPORT willremain inactive until a new Send Controller Data or Send

Send Controller DataCommands

Send Data Periodically

23

Data Periodically command is issued. If theDATAPORT receives a Send Controller Data commandwhile periodic transmissions are underway, it will imme-diately stop the transmission in progress and respond tothe newly received command.

Escape (1BH)

This command instructs the DATAPORT to stop sendingdata to the off-network device. The DATAPORT stopsat whatever point it has reached when the command isreceived and does not complete transmitting data fromany remaining points in the controller. Once this com-mand has been issued, the DATAPORT will not transmitany further data until it receives a new Send ControllerData or Send Data Periodically command.

Control/S or Control/s (13H)

This command instructs the DATAPORT to pause insending data to the off-network device. TheDATAPORT pauses at whatever point it has reachedwhen the command is received and does not complete itstransmission until it receives an XON command. Oncean XOFF command is issued, the DATAPORT will notrecognize any command except XON.

24

Control/Q or Control/q (11H)

This command instructs the DATAPORT to resumesending data to the off-network device after an XOFFcommand has made it pause. Transmission resumesfrom the point it had reached when the XOFF wasreceived. This is the only command that a DATAPORTwill recognize after it receives an XOFF command.

Control/N or Control/n (0EH)

This command instructs the DATAPORT not to includethe 24 character point descriptions in the data it trans-mits. Once this command is issued, the descriptions willbe omitted from all future transmissions until an Include24 Character Description command is issued.

Control/D or Control/d (04H)

This command instructs the DATAPORT to include the24 character point descriptions in the data it transmits.The DATAPORT’s default condition is to transmit thedescriptions, so the only reason to issue this command isto countermand a previous Omit 24 Character Descrip-tion commnad.

Control/T or Control/t (14H)

This command instructs the DATAPORT to read thestatic data (point names, units, and descriptions) from allof the up to 15 controllers from which it may transmitdata. The DATAPORT stores the static data for eachpoint in its database to be transmitted along with thepoint’s dynamic data (value and status). The

Read Configuration

25

DATAPORT reads static data from the controllers twominutes after it is prowered up, when it is downloadedwith a changed configuration table, and in response tothis command. This Read Configuration commandshould be issued from the off-network device any timechanges are made to point names, unit designations, orpoint descriptions in the controller(s) from which theDATAPORT is to transmit data.

If the DATAPORT cannot successfully respond to a command fromthe off-network device, it will instead return an error code to the off-network device. There are six error codes, represented by the ASCIIdigits 1 through 6.

A complete error message from the DATAPORT consists of anASCII Formfeed control character, followed by the error code,followed by two ASCII Carriage Return control characters.

The following paragraphs describe the interpretation of the sixDATAPORT error codes.

The digit 1 returned as an error code means that the lastASCII character sent to the DATAPORT by the off-network device is not one that the DATAPORT recog-nizes as a command.

The digit 2 returned as an error code means that the off-network device has commanded the DATAPORT totransmit data from a controller that is properly config-ured in the DATAPORT, but the controller does notcontain a point display table.

Error Codes

1 Invalid Command

2 No Display Table

26

The digit 3 returned as an error code means that theDATAPORT cannot transmit data from the requestedcontroller because a communication error occurred whilethe DATAPORT was acquiring data from that controller.

The digit 4 returned as an error code means that the off-network device has commanded the DATAPORT totransmit data from a controller that is properly config-ured in the DATAPORT, but the controller is beyond the900 point limit. For example, if controllers 1 through 10each contain 90 points, a command for the DATAPORTto transmit data from controller 11, 12, 13, 14, or 15 willresult in error code 4.

The digit 5 returned as an error code means that a staticdata update is in progress, preventing the DATAPORTfrom responding successfully to a Send Controller DataCommand or a Send Data Periodically command.

The digit 6 returned as an error code means that the off-network device has commanded the DATAPORT totransmit data from a controller that is not configured inthe DATAPORT. For example, if only controllers 1through 5 are configured in the DATAPORT, a com-mand of 0 (Send Controller Data for Controller 15) willresult in error code 6.
