Multiple remote indicators may be driven by the controller. For current (ma) options, the remote indicators are connected in series. The sum of the input resistance for all remote indicators must be less than 00 ohms. For voltage options, the remote indicators are connected in parallel. The sum of the currents for all remote indicators must be less than 0 ma. Three remote communications options are available for the CN00 which allow interfacing to remote devices utilizing the most common industry standards: RS and RS. Remote s RS- This method allows bidirectional data transfer via a threeconductor cable consisting of signal ground, receive input and transmit output. It is recommended for communication distances less than 0 feet between the computer terminal and the instrument. Note: Multiple instruments cannot be connected to the same port. The RS port is optically isolated to eliminate ground loop problems. Typically, Data Out of the computer/ terminal connects to the RCV terminal. Data In connects to the XMT terminal. If shielded cable is used, it should be connected to the frame ground at one end only. Signal ground is to be connected at appropriate ground terminals (refer to wiring diagram on next page). RS- The RS multipoint capability allows up to controllers to be connected together in a half-duplex network or up to 00 controllers with an appropriate communications repeater.
9 Note: Call factory for a recommended RS converter. Figure a. Wiring diagram for RS- digital communications. RX TX 0 0 FEET OR LESS GND FIELD CONNECTIONS This method allows bidirectional data transfer over a twisted pair cable. The twisted pair cable is a transmission line; therefore, terminating resistors are required at the most distant ends of the line to minimize reflections (typically 0 ohms at each end). The RS circuit is fully optically isolated, eliminating ground loop problems. Parallel drops from the transmission lines should be kept as short as possible; however, the line may be daisy-chained at each controller. The polarity of the line is important and each device will specify an A (+) and B (-) connection. TX RX D-SUB STYLE PIN MALE COMPUTER Figure b. Wiring diagram for RS- digital communications.

In this manual, the word host refers to the personal computer that s communicating with the controllers in the serial link, and the word slave refers to the controllers themselves. All transactions between the host and the slaves are done with messages consisting of only printable ASCII characters. There are only two primary types of messages: Requests and Responses. Messages coming from the host are called requests and messages coming from the slaves are called responses. With the exception of a broadcast request, for every request sent from the host, the slave will send back a response. If a slave does not respond within 00 milliseconds, then the request can be considered lost. A broadcast request is a request having an ID of 00 (see Message Formats on next page). It is used to address all slaves on the network. All slaves on the network will perform the actions requested in a broadcast message. However, a response message will not be returned. Therefore, the host can only broadcast Write or Auxiliary Command Requests. All slaves will ignore all Read Broadcast Requests. 0 OHMS LAST CONTROLLER TERMINATION (UP TO CONTROLLERS)
10 Menu Omega+ Protocol (Standard) Message Formats All Omega+ messages adhere to the general format of: [START CHAR][ID][ZONE][TYPE][PARAM][ERROR] [DATA][CHKSUM][END CHAR] START CHAR This is a single character which designates the start of the message. For a Request message, this character is the ASCII $ and for a Response message, this character is the ASCII %. Defined as start bit / N# data bits / Parity odd, even, none / N# stop bits ID This is a two-character ID identifying the receiving controller. Controller IDs go from - inclusively and all slaves in the network must have unique IDs. The ID number of 00, when used in a request, designates a broadcast message that is used to address all controllers in the network. See the section Request Message for an explanation of the broadcast message. In order to represent with just two ASCII characters, a number system known as the Message Code Numbering System is used. In this system, the most significant digit is represented with the numbers 0- and the letters A-Z and the least significant digit is represented with the numbers 0-.
11 The numbers 0- have the same values as their decimal counterparts and the letters A-Z have the values of 00-0 inclusively in increments of 0. Type This is a single character identifying the type of message. The following table lists the type characters for all messages. Example: Message Code Value = Decimal Value = = A = 00 A 00 + = 0 B 0 + = P 0 + = Zone This is a two character ID identifying the Zone number in multi-zone capable controllers. For the CN00, this number must be 0. TYPE character R r W w A Message Type Read Request or Read Response Returning a Positive Result Read Response Returning a Negative Result Write Positive Value Request and Response Write Negative Value Request and Response Auxiliary Command For further information, see following sections on the different message types. 0
12 PARAM This is a two character, message specific, parameter ID. For a Read/Write Request or Response message, this ID identifies the controller parameter. For an Auxiliary Command Request or Response message, this ID specifies the command. STATUS This is a single-character field used in all response messages, containing a status code specifying the status of the request message received. IMPORTANT: The data field in the Read and Write Request and Response messages must and will only contain the characters 0 -, and the decimal point.. All other characters are considered illegal. When the data field is listed as Unused or Ignored in an auxiliary command, it does not mean that the field can be skipped when sending in the request message. Instead, this field must be padded with any 0 alphanumeric (only letters and numbers are allowed) ASCII characters. DATA This field contains the ASCII representation of the value of the parameter. For the Auxiliary Request or Response messages, this field either contains the ASCII representation of a numeric value or just ASCII data. The length of this field depends on the message type. The discussion on the specific message types gives the exact requirements for this field. All ASCII representations of numeric values must be done using the characters 0 -, and.. Any use of other ASCII characters, including and - will result in a bad message. Negative numbers CANNOT be represented by preceding the number with - character. Instead, a special message type is used. See subsequent sections for more information.
13 Examples of valid numeric representations for a character data field: Numeric Value.0000 ASCII Representation CHKSUM This is a two character Message Code Numbering System, representing the sum of all the ASCII values of all the characters (excluding the START, CHAR, the END CHAR, and the CHKSM themselves) in the message. The sum is computed using the following formula: CHKSM = SUM(All Message Characters)% % represents the modulus operator. END CHAR This is a single character designating the end of the message. For all messages, the character used is <CR>, the carriage return. Examples of invalid numeric representations for character data field: (B represents a blank, or a space, character) Numeric Value Bad ASCII Representation Why? BBBBB Leading blanks.0bbbb are not allowed. Trailing blanks are not allowed is not allowed. Request Messages: Request Messages are sent from the host to the slaves. Each request will have an ID identifying the intended recipient of the request. If the ID is 00 (zero), then the request is a broadcast message. All slaves will perform the action requested in the broadcast request. However, a response message will not be returned. Therefore, it only makes sense to send Write or Auxiliary Command Requests as broadcast requests. There are three types of Request Messages: Read, Write, and Auxiliary Commands.
14 The Read Request: The Read Request is used to query parameter values and it has the following message format: [START CHAR][ID][ZONE][TYPE][PARAM][CHKSUM][END CHAR] Field Description: TYPE Must contain the uppercase letter R. Request Message $ØØRØC<CR> $ØØRØC<CR> $ØØRØC<CR> Description Queries the value of the Process Variable of Controller #. Queries the value of the EEPROM Setpoint of Controller # Queries the value of the EEPROM Setpoint of Controller #. END CHAR CHKSUM PARAM TYPE ZONE ID START CHAR Examples of the responses to these requests are given in later sections on Response Messages. The Write Request: The Write Request is used to modify parameter values and it has the following message format: [START CHAR][ID][ZONE] [TYPE][PARAM][DATA][CHKSUM][END CHAR] Field Description: TYPE This field must contain one of the following two characters. Request Message W Value in DATA is a positive value. w Value in DATA is a negative value. DATA A six-character ASCII representation of a numeric value. Description $ØØWØØ.G<CR> Change both the RAM and EEPROM copies of Setpoint # in controller # to the value of 0. $ØØwØØ.J<CR> Change only the RAM copy of setpoint # in controller # to the value of -0. (notice the lowercase w ). END CHAR CHKSUM DATA PARAM TYPE ZONE ID START CHAR
15 The Auxiliary Command Request: The Auxiliary Command Request is used to issue commands to the controllers and it has the following message format: Field Description: TYPE This field must contain the uppercase letter A Request Message $ØØAØXXXXXXXXXXL<CR> $ØØAØØØØ.ØØØØØ<CR> DATA A ten-character ASCII representation of a numeric value or 0 alphanumeric ASCII characters. Description Tell controller # to load all parameters with their defaults. The 0 X s are padding characters. Tell controller # to perform a low RTD calibration. Response Messages: Response Messages are replies to the requests sent from the host. For each request received, the slave will reply back with a response. For all requests, the Omega+ Protocol specifies a maximum response time of 00 milliseconds. If a response is not received after 00 milliseconds, that request can be considered lost. There are three types of Response Messages: Read, Write, and Auxiliary Commands. END CHAR CHKSUM DATA PARAM TYPE ZONE ID START CHAR
16 The Read Response: The Read Response will be sent in response to a Read Request. Some examples: The Write Response: The Write Response will be sent in response to a Write Request. Some examples: Request Message Description Request Message Description %ØØRØØ.K<CR> %ØØRØG<CR> %ØØrØØ.ØØØN<CR> The value of the Process Variable is. Degrees C.
