13. Since some HART commands have variables for writing the command will be composed of the parameter to be changed and the parameters described in the command definition HCD block As the parameter does not inform which HART command should be used to write The writing and reading parameters many times are not the same it is necessary an additional configuration for the parameters to be written Such additional configuration is done in the HWPC block because it has the correlation between these parameters and the HART commands used for writing The HWPC has the same identification code as the corresponding HCD therefore the entire configuration for a HART device should have HWPC pair A writing request starts a process with the following stages 1 After the parameter had received the writing command the HI302 checks the HWPC block to know whether that parameter can be written that is if it has a configuration to write If the parameter has such a configuration the HI302 stores the value received in a temporary variable and starts the writing process in the device If the parameter does not have this configuration the HI302 returns a standard response indicating that the parameter cannot be written IMPORTANT In case the parameter does not accept writing check if the HI302 supports the specific commands of the HART device and if the HWPC configuration is correct 2 parameter can be written the writing reque

Each Request parameter is described by two types of information the TYPE 1 byte and the LENGTH 1 byte for STRINGS or CONSTANTS besides the relative index and the sub index corresponding to the HIRT or HVT block where the parameter is stored that is from which parameter the value will be read to form the HART command The parameters are described by their sending sequence in the HART frame Even if the parameter is from a different type the HI302 converts automatically Remember that the DATA TYPE should always appear in the documentation of the HART command and not in the parameter type of the FOUNDATION fieldbus block The parameters are described in order in the HART frame Response Parameters The Response parameters are described the same way as the Request parameters immediately after most significant bit should be in the RESPONSE DATA TYPE field The remaining bits indicate the data type that have to be sent via HART command as seen previously The data type indicated is the data type that will be packaged in HART frame and is not the type of FOUNDATION fieldbus parameter because it will be converted before the HART frame is arranged There is an implicit conversion for reading and storage data 4 4 Advanced Configuration When the type of data is Packed ASCII ASCII or Constant the definition will have a second byte string length that will indicate the string length that must be read and saved in

EL parameter is the HART TAG and not the HIRT block TAG Check if the HI302 has the configuration for the desired HART device The HI302 uses the MAN ID TYPE UNI REV SPEC REV and SW REV parameters to find the configuration in the memory The read value does not correspond to the HART device variable Check if EXEC STATE UPDATED The parameters related to the HART variable are valid if the EXEC STATE UPDATED For the HVT block make sure the read parameter corresponds to the desired variable See the HVT block allocation map cannot write in the parameter Does the parameter correspond to a HART variable that can be written Is this reflected in the current device s configuration Check them Even for the HIRT block check if the device supports the HART command used for writing See on the Appendix section a detailed explanation about the commands used by the HIRT block for writing When attempting to program a new firmware a new version of the resident program the FBTools displays error message Check if the HI302 is in Bootloader mode In this mode only the ON green SAVING yellow and H1 green LEDs must be lit To access the Bootloader mode press the RESET button for 5 seconds with the module started up By pressing again the RESET button after the programming is done the module will start executing the new resident program 8 2 02 User s Ma

EV parameter of the corresponding HIRT block is increased and will indicate that a parameter was changed Variable Writing and Reading An operation model based on reading cycles and writing requests was designed to make the HI302 use as simple as possible HART variables Reading Cycles The variable reading is almost always done in group because of the HART command structure Therefore the HI302 variable readings are done through cycles that is the HIRT block always updates several parameters at the same time except the writing When the HVT block is executed all of the reading commands from the device configuration are executed at the same time following the configuration sequence See the Appendixes When the HIRT block detects any change in the device EXEC STATEZOLD it starts an update process and sends again all the reading parameters of the configuration The applicative checks if the ST REV was changed and begins to execute the HVT block for the device Writing on parameters that map the HART variables Unlike the reading writing on parameters that map HART variables is done separately for each variable IMPORTANT Not all parameters related to HART variables allow writing Writing depends on the device s HART version If the user has any doubt about writing on parameters check the HIRT block documentation as well as the HART commands supported by the device 5 5 HI302 User s Manual

SAVING The HI302 module has a serial EEPROM to store non volatile data from its configuration However to avoid the premature wear off of the memory a mirror of its contents in SRAM is used While this LED remains lit avoid the HI302 to be switched off or reset as this will indicate that static data from the SRAM mirror is being saved on the EEPROM After sending the configuration to the HI302 this LED may be lit for a few minutes while data is being saved permanently on the EEPROM If it is turned off or reset this configuration will be lost and must be sent again H1 LED This LED indicates that an activity is going on in the fieldbus communication At each information package sent by the HI302 the LED will blink If the LED does not blink it indicates that the HI302 is not communicating with the net Check the H1 segment configuration LAS Then switch off the 02 and restart it a few seconds later If it does not return to the Live List after a few minutes try a Init If this step fails send the HI302 to maintenance CH 1 to CH 8 LEDs These LEDs indicate the situation on every HART channel under the following statuses e Unlit the channel is active but there is no HART communication The devices of the channel may have problems or their HIRT blocks are in OS Out of service mode Check the devices and their block configurations e Lit indicates the HART communication is deactivated the COMM ENABLE parame

143. nual Questions and Answers Next see some of the most common questions about the HI302 1 Does the HART communication interfere in the 4 20mA control signal No The HART communication is imposed by a modulated signal in FSK Frequency Shift Keying over the current signal generated or received by the device in a frequency usually ranging from 500 Hz to 4 KHz According to the theory of communications a signal modulated in FSK has an average value equal to 0 and therefore no disturbance is caused on the control signal Thus the HI302 module may be connected to any existing installation The wiring used in the HI302 s installation may be a noise receiver source and cause interference in the control loop To avoid such problem the user should use a shielded cable with the minimum length and with good electrical connection 2 Does the HI302 work with third party devices that is those not made by Smar Yes HI302 was designed to work with any devices that comply with HCF HART Communication Foundation standard The most used universal and common practice commands are supported by the 02 through the HIRT block with no need for a special command configuration If the user wants to use the device s complete set of commands Common Practice and Specific Commands a specific configuration must be loaded based on the device documentation For Smar devices this configuration is already built in the HI302 s memory 3 link the
