Hardware The backplane board provides the power regulation, the routing of the signals

to the termination board, the processor board, the backup battery board, the optional communications board, the sensor module, and the battery charger board.

The termination board provides connections to the field wiring and is located on the terminal side of the housing. Connections include the power supply, Local Operator Interface (LOI) communications, Comm 1 communications, optional Comm 2 communications, RTD wiring, and the I/O field wiring. The termination board provides surge and static discharge protection for the field wiring. Electronics include the RTD circuits and the final I/O drivers/receivers. The termination board also serves as an interface to the backplane board in the electronics portion of the enclosure.

The 32-bit processor board contains the processor, memory, Local Operator Interface (LOI) communications driver, Comm 1 communications driver, the reset controller, and the real-time clock. The functions for the I/O of analog conversion originate on the processor board. The processor board, also called the central processor unit, provides the Serial Peripheral Interface (SPI) buss, Liquid Crystal Display drivers, and Sensor module.

The microprocessor has low-power operating modes, including inactivity and low battery condition. The 3095FC comes standard with 512 KB of built-in, static random access memory (SRAM) for storing data and history. The 3095FC also has 2 MB of flash ROM for storing operating system firmware, applications firmware, and configuration parameters.

The charger board controls the charging of the internal batteries, if installed. Three D-size lead-acid batteries provide 2.5 Amp-hours of current at 6.2 volts nominal. The charger board also serves as the interface to the optional LCD assembly, as well as supporting the On/Off and Norm/Reset jumpers.

A backup battery provides backup power for the static RAM and the Real-Time Clock. This battery is field replaceable. Under normal conditions, the battery has a functional life that exceeds five years.

An RTD temperature probe typically mounts in a thermowell on the meter run. The RTD measures the flowing temperatures under a constant current drive. The RTD wires connect directly to the RTD connector on the termination board located inside the enclosure.

The built-in inputs and outputs (I/O) on the 3095FC consist of a port for a 3-wire 100-ohm RTD input interface. Three diagnostic analog inputs (AI) monitor the battery voltage, logical voltage, and enclosure/battery temperature.

The Local Operator Interface (LOI) port provides a direct link between the 3095FC and a personal computer (PC) through a Local Operator Interface Cable using EIA-232 (RS-232) communications. Configure the functionality of the 3095FC and monitor its operation using Rosemount User Interface Software (see Section 3: Configuration).

The Comm 1 allows for EIA-485 (RS-485) serial communication protocols. The EIA-232 (RS-232) activates Comm 2. “Establishing Communication” on page 2-13

Rosemount 3095FC

Firmware The firmware contained in flash ROM on the termination board, determines

the functionality of the 3095FC and includes:

• 1992 AGA-3 flow calculations (with user-selectable AGA8 compressibility Detail, Gross I, or Gross II) for a single meter run

• Memory logging of 240 alarms and 240 events

• Archival of minute data from the last 60 minutes for 15 points

• Archival of 60 days of 10-minute data for 4 points

• Archival of 35 days of hourly data for 15 points

• Archival of 35 days of daily data for 15 points

• Archival of Min / Max historical data for today and yesterday

• Communications based on Modbus slave, (ASCII or RTU) protocol for use with EFM applications

• User level security

Accessories The 3095FC supports the following options and accessories:

• Local Operator Interface (LOI) cable

• Liquid Crystal Display (LCD) with two-line alphanumeric viewing. The LCD automatically displays information at 3-second intervals.

• Solar panel mast assembly (installed to recharge the backup battery)

Automatic Tests The 3095FC performs the following self-tests on a periodic basis:

• Battery low and high

• Software and hardware watchdog

• RTD automatic temperature compensation

• Sensor operation

• Memory validity

The 3095FC will operate with its internal batteries down to 5.4 VDC. The LCD becomes active when input power with the proper polarity and startup voltage (typically set greater than 8.0 Volts) is applied to the CHG+ connector (provided the power input fusing/protection is operational). The battery and logical voltage tests ensure that the 3095FC is operating in the optimum mode.

The software watchdog is controlled by the central processor unit (CPU). The software will arm the watchdog timer every second. If the watchdog timer is not armed for a period of 6 seconds, then the watchdog timer forces the 3095FC unit to reset. If necessary, the software automatically resets. The hardware watchdog is controlled by the CPU and monitors the power to the hardware. If the battery voltage drops below 5.4 volts, the 3095FC automatically shuts down.

The Rosemount 3095FC monitors its orifice-metering measurement for accurate and continuous operation.

October 2004

Low Power Mode Sleep mode is used to place the CPU in a low power mode. The battery

voltage is monitored by low voltage detection circuitry and the low voltage limit value is set at 5.4 volts. During Sleep mode, sub-modules are powered down. The 3095FC enters Sleep mode after one minute of inactivity on the communication ports.

Wake-up from Sleep occurs when the 3095FC receives a:

• Timed interrupt from the Real-Time Clock

• Signal from one of the communication ports

3095FC Functions Most of the 3095FC functions are determined by the firmware. The features

and applications provided by the firmware, which must be configured by using Rosemount User Interface Software, include:

• Flow calculations for an orifice meter

• Extensive historical data archival

• Memory logging of 240 alarms and 240 events

• Security with local and remote password protection

Flow Measurement

The primary function of the 3095FC is to measure the flow of natural gas through an orifice in accordance with the 1992 American Petroleum Institute (API) and American Gas Association (AGA) standards.

The primary inputs used for the orifice metering flow measurement function are DP, SP, and temperature. The DP and SP inputs are sampled once per second. The temperature input is sampled and linearized once per second from an RTD probe.

1992 Flow Calculations for Orifice Metering

The 1992 flow calculation is in accordance with ANSI/API 2530-92 (AGA Report No. 3 1992), API Chapter 14.2 (AGA Report No. 8 1992 2nd printing

1994), and API Chapter 21.1. The 1992 flow calculation may be configured for either Metric or U.S. units.

Flow Time

The DP stored for each second is compared to the configured low flow cutoff. If the DP is less than or equal to the low flow cutoff or the converted SP is less than or equal to zero, flow is considered to be zero for that second. Flow time for a recalculation period is defined to be the number of seconds the DP exceeded the low flow cutoff.

Input and Extension Calculation

Every second the Rosemount 3095FC stores the measured input for DP, SP, and temperature and calculates the Integrated Value (IV) (the square root of the absolute upstream SP times the DP).

1-4

Flow time averages of the inputs and the IV over the configured calculation period are calculated, unless there is no flow for an entire calculation period. Averages of the inputs are recorded to allow monitoring during no flow periods.

Reference Manual

00809-0100-4832, Rev AA October 2004

CONSIDERATIONS

Rosemount 3095FC

Instantaneous Rate Calculations

The instantaneous value of the IV is used with the previous calculation period of the Integral Multiplier Value (IMV) to compute the instantaneous flow rate. The IMV is defined as the value resulting from the calculation of all other factors of the flow rate equation not included in the IV. The instantaneous flow rate is used with the volumetric heating value to compute the instantaneous energy rate.

Flow and Energy Accumulation

The averages of the DP and SP, temperature, and sum of the IV are used with the flow time to compute the flow and energy over the calculation period. The flow and energy are then accumulated and stored at the top of every hour. At the configured contract hour, the flow and energy are stored to the Daily Historical Log and zeroed for the start of a new day.

Environmental Requirements

The 3095FC is designed to operate between -40 to 75°C (-40 to 167°F). When mounting, ambient temperatures may effect the operating temperature. Operation beyond the recommended temperature range may cause measurement error and erratic performance.

The 3095FC should not be exposed to levels of vibration that exceed 2g for 15 to 150 Hz and 1g for 150 to 2000 Hz.

Enclosures The 3095FC is packaged in a NEMA 4 windowed enclosure The enclosure is

fabricated from die-cast aluminum alloy with iridite plating and paint. There are two ¾-in. pipe threaded holes for field conduit wiring, and communications.

Mounting Provide adequate clearance for wiring, service, and solar panel. Mount on a

pipestand or to an orifice plate using a 3- or 5-valve manifold. The LCD display can be rotated 90 degrees in either direction.

For solar-powered 3095FC units orient solar panels as follows:

• Northern Hemisphere: due south (not magnetic south)

• Southern Hemisphere: and due north (not magnetic north)

• Sunlight is not blocked from 9:00 AM to 4:00 PM.

Power Installation Requirements

The primary power source is provided through DC voltage sources or solar power. Route power away from hazardous areas, sensitive monitoring devices, and radio equipment. Adhere to all local, company, and National Electrical Code (NEC) requirements for power installations.

The 3095FC accepts input voltages from 8.0 volts to 28 volts at the charge (CHG+ / CHG-) terminals on the termination board. The maximum power for DC voltage sources is 130 mW, not including battery charging.

An external solar panel connects to the CHG+ / CHG- inputs on the termination board. Circuitry on the battery charger board monitors and regulates the charge based on battery voltage, charging voltage, and temperature. The 3095FC requires a minimum 8-volt 200 mA solar panel.

Rosemount 3095FC

Solar Panels Solar panels generate electrical power for the 3095FC from solar radiation.

They are the optimal choice for locations where a DC voltage source is not available. The size of solar panels required for a particular installation depends on several factors, including the power consumption of all devices connected to the solar array and the geographic location of the installation. An 8-volt solar panel can provide charging power for the backup batteries (see “Solar Panel Sizing” for information on how to determine the appropriate panel size required for an application).

An external solar panel typically mounts to the same 2-in. pipe that supports the 3095FC (see “Mounting” on page 2-1). The panel wiring terminates at the charge (CHG+ / CHG-) power terminals on the termination board.

NOTE:

Solar panel size may violate certain CSA Class I, Division 1 ratings. Use approved 3095FC enclosure connectors for routing the power wiring.

The optional solar panel is adequate for support of API Chapter 21.1 compliant measurement and the retrieval of the historical logs once a day using the internal communication methods.

Solar Panel Sizing

To determine solar panel output requirements, first determine the solar insolation for the geographic area. The map in Figure 2-1 shows solar insolation (in hours) for the United States during winter months. Contact an Emerson Process Management representative for a map detailing a specific geographic area.

Insolation (from map) = _____ hours

Next, calculate the amount of current required from the solar array per day using the following equation. I

= [ISF (amps) ´ 24 (hrs)]/Insolation (hrs) = _____ amps

array

Finally, the number of solar panels can be determined using the following equation:

Ground the Transmitter Grounding reduces the effects of electrical noise on the unit's operation and

protects against lightening. The 3095FC provides lightening protection for built-in field wiring inputs and outputs. Install a surge protection device on the DC voltage source system to protect the device against lightning and power surges.

The 3095FC has two grounding screws inside the enclosure. It is recommended that a minimum of 14 AWG wire be used for the ground wiring. To minimize signal errors caused by EMI (electromagnetic interference), RFI (radio frequency interference), and transients, The I/O signal wiring cable should be an insulated, shielded, twisted-pair. All grounds should terminate at a single point.

NOTE

Grounding wiring requirements for DC voltage sources equipment are governed by the National Electrical Code (NEC). When the equipment uses DC voltage sources, the grounding system must terminate at the service disconnect. All equipment grounding conductors must provide an uninterrupted electrical path to the service disconnect.

All earth grounds must have an earth to ground rod or grid impedance of 25 ohms or less as measured with a ground system tester. The grounding conductor should have a resistance of 1 ohm or less between the 3095FC enclosure ground and the earth ground rod or grid.

Pipelines With Cathodic Protection

The 3095FC must be electrically isolated from the pipeline. Electrical isolation can be accomplished by using insulating flanges upstream and downstream on the meter run. In this case, the Rosemount 3095FC could be flange mounted or saddle-clamp mounted directly on the meter run and grounded with a ground rod or grid system (see “Earth Grounds” on page 2-8).

2-8

Reference Manual

00809-0100-4832, Rev AA October 2004

Pipelines Without Cathodic Protection

The pipeline may provide an adequate earth ground and the 3095FC could mount directly on the meter run using an orifice plate. Use a ground system tester to make sure the pipeline to earth impedance is less than 2 ohms. If the pipeline to earth impedance is greater than 2 ohms, the 3095FC installation should be electrically isolated and a ground rod or grid grounding system installed. If the pipeline provides an adequate ground, a separate ground rod or grid system may not need to be installed.

Rosemount 3095FC

POWER SUPPLY The 3095FC accepts input voltages from 8.0 volts to 28 volts at the power

terminals (CHG+ / CHG-) with no external current limiting (internal current limit is 200 mA). The CHG+ / CHG- terminal can accommodate up to 16 AWG wire.

To adequately meet the needs of the 3095FC system, it is important to determine the total power consumption and size of solar panel requirements accordingly. To determine the total 3095FC power consumption, be sure to add the power consumption (in mW) of any other devices used with the 3095FC in the same power system. The maximum power for DC voltage sources is 130 mW not including the battery charging.

Convert the total value (in mW) to Watts by dividing it by 1000.

mW / 1000 = Watts

For selecting an adequate power supply, use a safety factor (SF) of 1.25 to account for losses and other variables not factored into the power consumption calculations. To incorporate the safety factor, multiply the total power consumption (P) by 1.25.

PSF = P x 1.25 = _____ Watts

To convert PSF to current consumption in amps (ISF), divide PSF by the system voltage (V) of 12 volts.

ISF = PSF / 12V = _____ Amps

Batteries

Batteries provide power for the 3095FC when the solar panels are not generating sufficient output. The batteries are three D-size lead-acid batteries providing 2.5 Amp-hours of current at 6.2 volts.

The batteries are connected in series by the Battery Charger Board to achieve the required capacity. The battery capacity determines the number of days of reserve (autonomy) desired.

When the 3095FC is configured as an API compliant Electric Flow Management (EFM) and requires an internal communications card, a solar panel, and the internal batteries, the 3095FC should be able to communicate the API audit trail information once a day to a remote host using no additional battery source, no additional solar panel, and maintain a 13 day autonomy in the event that the solar panel is lost.

To determine the system capacity requirements, multiply the system current load (ISF) on the batteries by the amount of reserve time required. Compute “ISF” as described above. The equation is as follows:

System Requirement = ISF amps x Reserve hrs = _____ amp-hrs

Configuring the System Flags

Use System Flags to perform actions that affect the overall operation of the 3095FC. From the Flags screen, a configuration can be saved to Flash memory and the 3095FC can be re-initialized.

NOTE

Certain Flags cause data to be lost, parameter values to be changed, and configuration memory to be cleared. Confirm Flag function before changing.

General Tab

Figure 3-2 on page 3-6

After a Warm Start, the 3095FC is initialized from SRAM memory if the configuration is valid. If valid, the databases remain intact. If the memory does not have a valid configuration, the configuration that was last saved to Flash memory is used. To save a valid configuration, use the Save Configuration button.

In a Cold Start, the 3095FC is initialized from the restart configuration saved in the Flash memory. If the configuration memory does not have a valid configuration written in it, the factory defaults are used.

NOTE

Perform a Cold Start after setting the clock and BEFORE setting any other parameters to ensure the 3095FC memory is cleared before configuration begins.

Cold Start reloads all restart configuration data and may also clear logs and displays. In addition, it may cause output changes, load new accumulator values, and disable user program tasks and User Data Types. Generally, a Cold Start should not be used on a 3095FC that is actively gathering data or performing control. Save or document all required data and parameter values that could be affected before performing the Cold Start.

The following may occur when performing a Cold Start:

• Cold Start restores a configuration from default values stored in Flash

memory.

• Cold Start & Clear ALL restores a configuration from default values

stored in Flash memory and clears all History, Alarm Log/Event Log, and displays.

• Cold Start & Clear Alarms/Events restores a configuration from default

values stored in Flash memory and clears the Alarm Log/Event Log.

• Cold Start & Clear Displays restores a configuration from default values

4. Enter the RBX Host Address and Group number. The defaults of “1” and “0” are used by most host driver software.

5. Set the Delay to define the time, in seconds, between attempts to transmit an RBX message. There is a Delay parameter associated with each Retry Count parameter, allowing the user to identify different length delays for each entry.

6. The RBX Attempts #1 - 3 (Retry Count) is the number of attempts a message is repeated if a valid response is not obtained on the first attempt. Attempts include the initial message plus the retries. The three Retry Count parameters each have an associated Delay parameter. Selecting Fixed Number allows the user to enter a value for how many times a message is retried after the first unsuccessful attempt. Note that a “0” entry causes no retries. Selecting Continuous causes continuous retries that can only be stopped when the host clears the RBX alarm.

For example: If setting the Retry Count #1 to “2”, Delay #1 to “10”, Retry Count #2 to “1” and Delay #2 to “20”, then after the first unsuccessful attempt to communicate with the host, the 3095FC tries two more times after waiting 10 seconds each time, and once more after waiting 20 seconds.

7. Enabling the Extra Key On Delay to add an additional amount of time to delay transmitting an RBX message after turning the RTS signal on. The amount of time is fixed. This parameter is used for radio communications.

8. RBX ACK Timeout - This is a message from the Device. If the ACK fails to be received within the timeout period the 3095FC retries the RBX.

NOTE

The RBX Alarm Index indicates alarms currently being reported through the RBX. The RBX Status parameter indicates the status of RBX messaging, either Active or Inactive. Active indicates that an SRBX alarm is being processed.

9. After configuring the RBX function, use Device > Flags > Flash Memory Save Configuration to save the configuration to the Flash Memory in case a Cold Start must be performed.

Analog Input (AI) Configuration

Analog Inputs are analog signals generated by measurement devices, such as pressure and temperature transmitters, including RTD probes.

The following tabs are available as part of the AI configuration:

• AI General tab

• AI Advanced tab

• AI Calibration tab (see “Analog Input (AI) Calibration” on page 4-3)

• AI Alarms tab

AI General Tab

The AI General Table sets the basic parameters for the Analog Input point. Use the following steps to configure the AI General Tab.

See Figure 3-12

1. Select Device > I/O > AI Points > General Tab

2. Select the Analog Input.

3. Enter a 10-character Tag for identification of this Point Number.

4. Enter the Value and Units.

5. Select the Scanning option.

• When Scanning is set to Enabled, Value automatically displays

the last Analog Input scan in engineering units.

• When Scanning is set to Disabled (manual mode), the value is no

longer updated by the 3095FC. If Scanning is set to Disabled, enter a value to override the input. If Alarming is Enabled, an alarm generates when Scanning is set to Disabled.

6. Set the Alarming option. The Active Alarms field indicates any alarms that are active for this point. For example, when Alarming is Enabled, the limit alarms (such as Low Alarm and Rate Alarm) that are active appear. Even if Alarming is Disabled, the Point Fail (hardware reports a malfunction) alarm and Manual (Scanning Disabled) indicators can still appear.

7. Enter the Scan Period as the amount of time between updates of the filter value. All Analog Inputs are updated based on their individual Scan Periods. The default value is 1 second. The minimum Scan Period allowed is 50 msec.

8. Enter the Low Reading EU (engineering unit) corresponding to 0% input. Enter the High Reading EU corresponding to 100% input. For example: If a temperature transmitter is connected to the Analog Input with a range of -40 °F to 212 °F, the Low Reading EU would be set to -40 and the High Reading EU would be set to 212.

9. To complete point configuration click Apply.

AI Advanced Tab

The AI Advanced tab enables the user to configure features, such as filtering, A/D conversions, and clipping for the selected Analog Input. Use the following steps to configure the AI Advanced Tab.

See Figure 3-13 on page 3-18.

1. Select Device > I/O > AI Points > Advanced

2. Enter a Filter value, which is a weighted sample using a percentage of the last value plus a percentage of the new value. The entered data is the percentage of the last value used. The Filter is calculated every Scan Period by the formula:

(Last Value × Entered %) + (New Value × (100 - Entered %)) = Filtered Value

3. Enter the Adjusted A/D 0%, which is the calibrated Analog-to-Digital (A/D) reading that corresponds to 0%input. In the Calibrate function, this value is altered to set the 0% input exactly at the Low Reading EU value to eliminate transmitter and system errors.

4. Enter the Adjusted A/D 100%, which is the calibrated A/D reading corresponding to 100% input. This value is used to convert the input to engineering units. In the Calibrate function, this value is altered to set the 100% input exactly at the High Reading EU value.

NOTE

Raw A/D Input displays the current reading directly from the analog-to-digital converter. Actual Scan displays the actual amount of time in seconds that passes between scans. This number should be the same as shown for the Scan Period parameter if the system is not overloaded.

5. The Enable Average Raw Values calculates and averages the raw readings during the Scan Period. Use the outcome as the Raw A/D Input during calculations. For example: When Enabled, an Analog Input point configured with a Scan Period of 1.0 seconds obtains a new value from the A/D every 50 milliseconds. During the Scan Period, 20 values are obtained from the A/D and summed together. At EU Value calculation, the values summed are divided by the number of samples taken during the scan period and are used as the Raw A/D Input. Disable this function to acquire instantaneous values.

6. When Temp Compensation is Enabled, a temperature compensation curve is applied to the Analog Input using the board temperature of the 3095FC as a reference. Use this feature to improve the A/D conversion accuracy at temperature extremes for modular Analog Inputs only; built-in Analog Inputs already have temperature compensation. When using this feature, be sure to perform a calibration after it is Enabled.

7. When Clipping is Enabled, the 3095FC forces the Filtered EUs to stay within the range defined by the cut off limits. Set the cut off limits by using the LoLo Alarm and HiHi Alarm parameters (see “AI Alarms Tab” on page 3-19).

AI Alarms Tab

See Figure 3-14 on page 3-20.

The AI Alarms tab sets the alarm parameters for the AI point.

1. Select Device > I/O > AI Points > Alarms

2. Set the values for the different alarms. There are six different alarms:

• Low Alarm: The limit value, in engineering units, to which the I/O

must fall to generate a Low Alarm.

• High Alarm: The limit value, in engineering units, to which the I/O

must rise to generate a High Alarm.

• LoLo Alarm: The limit value, in engineering units, to which the I/O

must fall to generate a LoLo Alarm. The value is set lower than the Low Alarm.

• HiHi Alarm: The limit value, in engineering units, to which the I/O

must rise to generate a HiHi Alarm. The value is set higher than the High Alarm.

• Rate Alarm: The value, in engineering units, that represents the

maximum amount of change permitted between updates. If the change is equal to, or greater than this value, an alarm is generated. To disable the Rate Alarm without disabling the other alarms, the Rate Alarm value must be set greater than the Span of the Analog Input or TDI.

• Alarm Deadband - The value, in engineering units, is an inactive

zone above the Low Alarm limits and below the High Alarm limits. The purpose of the Alarm Deadband is to prevent the alarm from being continuously set and cleared when the input value is oscillating around the alarm limit. This prevents the Alarm Log from being over-filled with data.

3. Select RBX Alarming

• Disabled if limit alarms are not necessary for this point. Even if

Alarming is Disabled, the Point Fail (hardware reports a malfunction) alarm and Manual (Scanning Disabled) indicators can still occur. To conserve Alarm Log space, only Enable Alarming when necessary.

• If the host PC is configured to receive field-initiated calls, a

Report-by-Exception (RBX) option is available.

• On Alarm Set - When the point enters an alarm condition, the 3095FC generates a RBX message.

• On Alarm Clear - When the point leaves an alarm condition, the 3095FC generates a RBX message.

• On Alarm Set and Clear - When point enters and leaves an alarm condition, the 3095FC generates a RBX message.

Certain Opcodes only send data and do not receive data from the device. For example, Opcode 8 requests the device to set the time and date. The device resets the time and date and sends back an acknowledgement in which the Opcode is repeated, but no data bytes are transmitted back. All acknowledgements are 8-byte messages that repeat the Opcode received, but do not transmit any data bytes.

Opcode 255 is an error message indicator. This is also an 8-byte message with no data bytes included. The Opcode is set to 255 to indicate the message received by the device had Cyclical Redundancy Error, but contained invalid parameters. For example, if a request was made for the information on Analog input #9, but the device only has 8 Analog inputs (0–7), the device would respond back with the 8-byte message with the opcode equal to 255 (error).

Opcode Table Configuration

Use the Opcode Table to group data for more efficient communication. Parameters from different point types can be assigned to the Opcode table data points, substantially reducing the number of polls from a host PC.

See Figure 3-16 on page 3-23

1. Select Configure > Opcode Table.

2. Select the Table Number for the Opcode Screen.

3. If the configuration has changed, update the version number. The version number field attaches a version number to an Opcode table configuration. It is a floating point number.

NOTE

Each Opcode Data point has a TLP box for mapping TLP values into the Opcode Table Data point. If a host PC asks for a specific Opcode Data point, the 3095FC returns the value that is referred by the mapped TLP.

Radio Power Control Configuration

Figure 3-17. Radio Power Control Timing

Radio Power Control conserves battery power to a radio or any other communicating device. Radio power is controlled either by the DTR signal or by a Discrete Output (DO). Because there are separate Radio Control points for COM1 and COM2, radio power cycling for COM1 can be configured differently from that for COM2, including independent timer values and separate output controls using the Output Definitions options.

For each Radio Power Control point, the power cycling can be configured to automatically change three times a day. During each of these three periods (Zone 1, Zone 2, and Zone 3), the ON and OFF times can be setup to operate at various intervals. Figure 3-17 is a graphical depiction of how the power control operates within each time “zone.”

During the OFF time:

• The DO is set to OFF.

• Communication does not occur.

If communications occur during the ON time, the time is extended by the Hold Time. The DO remains ON and receives interrupts remain enabled for the duration of the Hold Time. When the Radio Power Control parameter is Enabled, radio power cycling is activated. The Low Battery Shutoff parameter allows power cycling to be automatically disabled whenever the input voltage to the 3095FC falls below the specified threshold.

3. Enter the The Radio Power Status, which indicates the current status of the Power Control function of ON, OFF, or RBX. The Active Zone indicates which zone is currently activated for determining the Start Time, On Time, and Off Time. Some of the On Time is also used by the radio during power-up initialization of the receiver, causing part of the On Time to be unavailable for receiving requests.

4. Select Radio Power Control Enabled to activate the Radio Power Control function.

5. Use the radio buttons to select Seconds and Minutes. In Seconds mode, the time base for the timers is in 0.1 second increments, primarily used with radios. In Minutes mode, the time base for the timers is in one-minute increments, primarily used with cellular telephones.

6. Enter the Zone parameters to indicate when Radio Power Control is active/inactive.

• Start Time that the respective Zone begins, in hours and minutes

(HHMM). Time is expressed in local time, 24-hour clock. For example: “1500” under Zone 2 means that the associated On Time and Off Time are used beginning at 3:00 p.m.

• On Time during a power cycle when the output is in the ON state.

• Off Time during a power cycle that the output is in the OFF state.

7. Enter the Hold Time that the output remains ON after detection of communications activity (in seconds, unless the Minutes mode has been enabled). This value applies to all Zones. When communications occur during the On Time, the On Time is extended by the Hold Time.

8. Enter the Low Battery Deadband. The Low Battery Deadband value is added to the Low Battery Shutoff to determine when the Radio Power Control function is enabled and allows the DO to turn ON as needed.

9. Enter a Low Battery Shutoff value that specifies the voltage at which Power Control is automatically disabled. The voltage being sensed is the System AI Battery Input voltage (0-1). The Low Battery Shutoff parameter allows power cycling to be automatically disabled whenever the input voltage to the 3095FC falls below the specified threshold. The default value is 11 Volts.

10. Select the Power Timer, which counts down the amount of time (On Time, Off Time, or Hold Time) that the Radio Control is currently using. The value is the number of seconds remaining.

11. Select which DO point the signal will send along.

Meter Run Configuration The Meter Setup screens allows configuring the AGA calculation point for the

connected 3095FC. The Meter Setup screens are used to configure the computation of gas flow through a meter (Orifice AGA3)

Each meter run must be uniquely identified to ensure proper configuration and allows the host to acquire the required data.

Each meter run Point Number is given a unique Meter ID of up to 10 characters to label the meter run for which this flow calculation is performed. Use the Meter Description field to enter up to 30 characters to further identify this meter run or provide information about the run.

The 3095FC uses AGA3 (1992) for flow calculation in orifice metering. Additionally, the AGA8 compressibility method is used as well. The AGA8 method calculates the compressibility factor based on the physical chemistry of the gasses at specified temperatures and pressures. The AGA8 method provides extended capabilities for accurate computation of compressibility factors beyond the temperature, pressure, and composition ranges of NX19.

History Points Configuration

The History option allows data stored in the current value database to be copied and stored for up to a month in the historical database. The historical database can be configured to log only the values that need to be logged. The values are logged in the standard (minute-hourly-daily) time base.

NOTE

The time stamp used for standard logging reflects the time at the end of the period, not at the beginning. For example: Data collected from 8:00 to 9:00 is stamped 9:00.

The 3095FC also maintains a 10-minute historical database.

Four types of historical databases are maintained:

• Min/Max Database (see “Meter History")

• Minute Database (see “General History")

• Hourly Database (see “General History")

• Daily Database (see “General History")

Meter History

The Min/Max Database is for viewing only and cannot be saved to a disk file. A total of fifteen history points may be accessed. For an AGA3 meter run, the first eight (out of fifteen) history points are pre-configured for flow metering history and cannot be changed. They are configured as follows:

• Alarm Log: The Alarm Log contains the change in the state of any

alarm signal that has been enabled for alarms. The system Alarm Log has the capacity to maintain and store up to 240 alarms in a “circular” log. The Alarm Log has information fields that include time and date stamp, alarm clear or set indicator, and either the Tag name or a 14-byte detail string in ASCII format.

In addition to providing functionality for appending new alarms to the log, the Alarm Log allows host packages to request the index of the most recently logged alarm entry. Alarm Logs are not stored to the flash ROM during the Save Configuration function in Rosemount User Interface Software.

The Alarm Log operates in a circular fashion with new entries overwriting the oldest entry when the buffer is full. The Alarm Log provides an audit history trail of past alarms. The Alarm Log is stored separately to prevent recurring alarms from overwriting configuration audit data.

• Event Log: The Event Log contains changes to any parameter within

the 3095FC made through the protocol. This Event Log also contains other 3095FC events, such as power cycles, cold starts, and disk configuration downloads. The Event Log provides an audit history trail of past operation and changes.

The system Event Log has the capacity to maintain and store up to 240 events in a circular log. The Event Log has information fields that includes point type, parameter number, time and date stamp, point number if applicable, the operator identification, and either the previous, current parameter values, and either the Tag name or a 14-byte detail string in ASCII format.

In addition to providing functionality for appending new events to the log, the Event Log allows host packages to request the index of the most recently logged event entry.

• Totalize - The difference between the current value and last hour's

current value is used for point values polled or received as accumulated values. The Totalization technique assumes that the value being archived is zeroed out by something else at Contract Hour and that no rollover of the value occurs. Totalization occurs at the Minute Historical Log and is summed up for the Hourly and Daily Historical Logs. A minute after Contract Hour, the current value is archived. All other minutes are the difference between the current value and the previous minute's archived value.

• Select Average Type -The Select Average Type parameter is set

to Average, this list appears at the bottom of the screen. Choose one of the following options to determine how the average value is calculated.

• Flow Dependant Linear - This is the default method for calculating the average for the flow input. It is the simplest and most commonly used method. This method discards samples for periods when there is no measurable flow and performs a straightforward (linear) average of the remaining samples to compute the minute and hour values. The value specified in the Low Flow Cutoff of the Meter setup determines the values. When no flow occurs, all values are sampled.

• Flow Dependant Formulaic - Like the Flow-Dependent Linear method, this method discards samples for periods when there is no flow. However, in calculating the average, this method typically takes the square root of each sample before averaging the samples together and then squares the result. This formulaic method produces a slightly lower value than the linear method.

• Flow Weighted Linear - This method does not discard any samples. Instead, it “weights” each sample by multiplying it by a flow value (square root of the DP measured during the sample period), and then performs a linear average by dividing the sum of the flow-weighted sample by the sum of the flow values. This results in minute and hourly values that are more reflective of short periods of high flow.

• Flow Weighted Formulaic - This method combines the flow-weighting action with the formulaic averaging technique, both of which were described previously.

9. Select Accumulation Time Basis - When the Selected Archive Type is Accumulate, this list appears at the bottom of the screen. Choose one of the following options to determine how the accumulated values are computed:

• Per Sec - Values summed to compute the second value.

• Per Min - Values summed to compute the minute value.

• Per Hour - Values summed to compute the hourly value.

• Per Day - Values summed to compute the daily value.

Scale Values Tab

The Scale Value tab allows the user to enter low and high floating point and integer values for converting between integer and floating point numbers.

See Figure 3-26 on page 3-43

1. Select Configure > Modbus > Configuration > Scale Values tab.

2. Enter the Integer Scale values. In the 3095FC, the endpoints of the Analog Inputs and the Analog Outputs are used to scale or calibrate the range of the input or output signal. Because each I/O point can have different scaling, the raw values from the Analog I/O points are normalized to the values defined by the Integer Scale Low Value and Integer Scale High Value fields.

3. Enter the Low Value that contains the 0% value for all analog data (Type 3, Parameter 17 and Type 4, Parameter 9) registers. Enter the High Value that contains the 100% value for all analog data (Type 3, Parameter 17 and Type 4, Parameter 9) registers.

NOTE

The High and Low Value fields are signed integers, so they can range from zero to 32767. These data fields can also be used to scale the Analog I/O to integer values with an implied decimal point. For example: All Analog I/O Raw values can be transmitted with 0 to 1000 values (0 to 100.0, decimal point implied) by setting the values in this field to 0 for the Integer Scale Low Value and 1000 for the Integer Scale High Value.

4. Enter the Float Scale # in the Low Value Float Scale and High Value Float Scale fields used when the Host is not able to process floating point numbers.

In Host systems that do not accept floating point numbers, eight sets of floating point ranges for values can be specified. This allows floating point values, such as PID Setpoints, to be read and set by the Host as integer values. The 3095FC floating point values are converted to integers by configuring a register or range of registers with the Conversion field set in the Modbus Registers Definition configuration.

The equations used to convert floating point values to integer values to enable the reading of floating point values are:

• Float Range = High Value Float Scale - Low Value Float Scale

• Integer Range = High Value Integer Scale - Low Value Integer Scale

• Adjusted Reading = Float Reading - Low Value Float Scale

• Integer = (Integer Range × Adjusted Reading)/(Float Range) + Low Value

Integer Scale

The equations used to convert integers to floating point values are:

• Float Range = High Value Float Scale - Low Value Float Scale

• Integer Range = High Value Integer Scale - Low Value Integer Scale

• Adjusted Integer = Integer Sent - Low Value Integer Scale

• Float Value = (Adjusted Integer × Float Range)/(Integer Range) + Low

Modbus - History Collection

The Modbus protocol sends the Hourly (periodic) and Daily History. Refer to “History Access Registers Tab” on page 3-44. Each record contains a time and date stamp and all of the history archives for which the Register Number is configured. The Modbus Function Code 03 and the History Archive Register are used to collect the archived data. Two Modbus registers indicate the current Hourly and Daily history index as selected in the Archive Type field. These can be configured in the Hourly History Index Register and the Daily History Index Register. These indexes identify the current history archive at which data was last logged.

To collect the Hourly and Daily history a standard Modbus Function Code 03 is used. The Register Number field is used to address the individual History Archive Register. The Daily Index, Hourly Index, and Event/Alarm data fields are used to address a history index number. The response message contains two floating point values for the time and date stamp of the history archive (time stamp = HHMMSS and date stamp = MMDDYY) and floating point values for each of the defined history points for that History Archive Register. The date stamp for history uses the current year and does not figure the number of years since 1980.

NOTE

When in Modbus with EFM extensions mode, the time stamp is in the HHMM format. In addition, the date time stamp is returned before the time stamp.

Table 3-5 summarizes the applicable function calls and their associated register and data fields.

Modbus - Events / Alarms Functionality

The record formats for the Event log and Alarm log are the same size and have similar contents. The first word in a record is a bit map in which bit 9 indicates if the log record is an Event (1) or an Alarm (0). The meanings of the other bits are specific to either the event or the alarm log records. The Event and Alarm log record consists of the bytes shown in Table 3-6. A breakdown of the bit map in the first byte is given in the table immediately after the record table.

The 3095FC supports the Modbus with EFM extensions method for retrieving alarms, events, and history. When a Function code 3 request referencing defined Events/Alarms Register (usually 32) is received, it begins to collect records from first the Event Log and then the Alarm Log, starting where the last poll left off. The 3095FC will collect records until either there are not any more new events/alarms or the maximum of twelve records have been collected. The 3095FC sends the information back to the host, which in return replies with Function Code 5, referencing the same Events/Alarms Register, indicating that the points have been received and that the host is ready for the next twelve records.

October 2004

When the 3095FC receives a Function Code 3 request referencing one of the user-defined Periodic History Registers or Daily History Registers, the number of registers field is interrupted as an index into the specific history log. The reply message contains the date and time stamp and historical values configured for the specified for that index.

Reading Events / Alarms Register

The Modbus request to read the Event/Alarm log (see Table 3-6) uses the standard read Function Code 03 and the Event/Alarm Register (parameter #0) in the Modbus Special Function Table (point type 39). In this request, the number of registers is included to maintain format compatibility but is ignored by the receiving 3095FC unit. For the date stamp in the events and alarms returned, the year (YY) is really the number of years since 1980 (for example, the current year is 1997, so the year (YY) for the date stamp would be 17).

Acknowledging Events / Alarms

The Modbus request to acknowledge the event/alarm log uses Function Code 05 and the Event/Alarm Register (parameter #0) in the Modbus Special Function Table (point type 39). In this request, the number of registers is always one (1).

Modbus - Detailed Point / Parameter Information

The Modbus Special Function Table (point type 39) returns the Event Log, Alarm Log, and the Historical Archives. The Event/Alarm Register (parameter #0), Hourly (periodic) History Index Register (parameter #1), and the Daily History Index Register (parameter #2) can be configured to the desired Register Number. The History Archive Register is a single register, which can contain one or more history points for retrieval. The Starting History Point field contains the Starting History Point for the History Archive Register, while the Ending History Point is the last history point to be included in the History Archive Register. All history points in between the Starting History Point and the Ending History Point are included in the History Archive Register. The Type of History Archive can only be one of two choices: Hourly or Daily. The Conversion Code can be used to convert the history values. However, the Conversion Code does not affect the time and date stamp.

The Modbus register configuration tables are used to associate Modbus register numbers with 3095FC point data. When a Modbus request is received, the Modbus user program searches the function table for the Modbus function requested, starting with the first table entry down to the last. If a register number match is found, it builds a response based on the point type and parameter configured in the table. If no register number match is located, an error message is returned. The user program locates a register as long as it matches the Starting Register number, the Ending Register number, or any number in between for that particular entry in the table.

Register numbers should be unique for a given communication port. Registers may be duplicated as long as they are assigned to separate port or located in a separate Modbus configuration table. If a register number is duplicated within the same Modbus function table, the first occurrence is used. In addition, it is best to number the table from the smallest register number to the largest register number, especially when using two table entries to configure a continuous group of registers. Up to fifteen different lines can be configured for Modbus Functions 4 and 16. Up to thirty different lines can be configured for Modbus Function 3, split into tables 3A and 3B. By making the registers continuous, meaning the Starting Register address of a new line is one greater than the Ending Register address of the previous line, a continuous data table can be created up for Modbus Function 3, 4, or 16 up to the limit of 240 bytes. This type of data table allows access to all its data with one request.

Up to fifteen different lines can also be configured for Modbus Function Codes 1, 2, 5, 6, and 15. For Function Codes 1, 2, 5, and 15, the parameter specified should be a single-byte parameter type, preferably a status parameter (only bit 0 is used), because this function packs the data into a binary format for transmission. Each address span must be unique within the function for proper operation. If not, the first valid address is used.

Modbus Register tables allow the user to map Modbus Registers to 3095FC Point Type, Logical, and Parameter (TLP) numbers. One line in the Modbus Register table can be used to map more than one register-TLP pair by using either Point Indexing or Parameter Indexing.

Point Indexing means that the Start Register is mapped to the selected TLP. Subsequent registers, through the End Register, are mapped to the same point type and parameter and increment as the point logical number.

Parameter Indexing means that the Start Register is mapped to the selected TLP. Subsequent registered, through the End Register, are mapped to the same point type and point logical number, and increment the parameter number.

Once a register is mapped, it can be referenced by any Modbus request, providing the data type of the TLP is appropriate for the Function Code. If the native 3095FC data type does not me the requirements of the Modbus host device, conversion codes are available to convert data to the required data type. The user can select to have the mapping apply to all 3095FC communication ports or on a selected port only.

Use the following steps to Configure the Modbus Registers.

See Figure 3-28 on page 3-51.

1. Select Configure > Modbus > Modbus Registers. (See Table 3-7 on page 3-49).

2. Select the Function Index to which the maps are to be registered. There are 9 function indexes available, each corresponding to a Function Code displayed in the Function name field. Refer to Table 3-2 on page 3-38 for a detailed description of supported Modbus Function Codes.

3. Enter a Function Name up to 20 characters to distinguish between the different Modbus Register tables.

4. Enter a Starting Register to represent the first data register in the address span. Any number from 0 to 65535 is valid. Register numbers can be duplicated as long as they are in separate Modbus Function configuration tables. The tables should be numbered from smallest to largest. For example, the Host device requests the Starting Register 500 through Ending Register 700. The Starting Register is 400 and the Ending Register is 700. All register numbers requested by the Host (500 through 700) are valid and would be responded because the requested register numbers fall between the Start and Ending Register numbers (400 through 700).

5. Specify that the Ending Register address is a number representing the last location of a point's data. The value for this number is computed by: Ending Register address = (Starting Register address + Number of Functions) - 1

6. The Device Parameter field denotes the type of data associated with an address (Starting through Ending Register). When the Host requests a valid range of register numbers, the Function Code tells the Slave what to do and between which registers (Starting Register through Ending Register). The Rosemount User Interface Software Parameter defines what data is collected or which parameter is set.

OVERVIEW Once startup is successful and configuration is complete, it is necessary to

calibrate the 3095FC to meet the requirements of the application. The following section details the procedure for calibrating the 3095FC and the I/O. Once calibration is complete the 3095FC can be placed into operation.

NOTE

When the enclosure end caps are unscrewed, local calibration or monitoring of the 3095FC through its LOI port must be performed in a non-hazardous area. Performance of these procedures in a hazardous area could result in personal injury or property damage.

CALIBRATE

3095FC Use the Rosemount User Interface Software to calibrate as follows:

1. Launch the Rosemount User Interface Software and connect to the 3095FC.

2. Select the Meter > Calibration. The current reading displays under each meter input as the Freeze Value. The 3095FC uses these values in the flow calculations while calibrating the points.

3. Click Freeze. If necessary, create a calibration file.

4. Isolate the device from the process by opening the by-pass valve on the valve manifold prior to isolating the device from the process (to protect the sensor module). This keeps one side of the differential sensor from being subjected to high pressure while the other side has no pressure applied. This is required when calibrating either DP or SP. See Figure 4-1.

5. To calibrate the pressure input, setup the pressure calibrator and make the necessary connections to the device.

6. To calibrate the temperature input, disconnect the RTD sensor and connect a decade box (or comparable equipment) to the RTD terminals of the 3095FC.

7. Click Calibrate under the desired input to calibrate DP, SP, or Temperature. This displays the Set Zero calibration window.

8. Apply the low (zero) value. For a pressure input, this would typically be open to atmosphere.

9. Enter the applied value in the Dead Weight / Tester Value field of the Set Zero dialog. For SP on an absolute-pressure device, enter the actual current atmospheric pressure.

NOTE

Apply pressure to both the high and low sides of the transmitter when calibrating SP.

10. When the displayed Live Reading is stable, click Set Zero to calibrate the zero reading. The Set Span window then appears

11. Apply the desired high value to the input (the top end of the expected operating range).

12. Enter the applied value in the Dead Weight / Tester Value field of the Set Span dialog.

• For SP on an absolute-pressure device, add the actual

atmospheric pressure, such as 300 + 14.73.

13. When the Live Reading is stable, click Set Span to calibrate the high reading. The window advances to the Set Midpoint 1 window.

14. To perform a two-point calibration, click Done to complete calibration.

15. To calibrate midpoints, apply the desired pressure or temperature and enter the applied value in the Dead Weight / Tester Value field. Midpoint can be calibrated in any order.

16. When the Live Reading is stable, click Set Mid 1 to calibrate the reading. The display advances to the Set Midpoint 2 window.

17. To perform a three-point calibration, click Done to complete calibration.

18. To calibrate additional midpoints, apply the desired pressure or temperature and enter the applied value in the Dead Weight / Tester Value field.

19. When the Live Reading is stable, click Set Mid 2 to calibrate this reading. The display advances to the Set Midpoint 3 window.

20. To perform a four-point calibration, click Done to complete calibration.

21. To calibrate a third midpoint, apply the desired pressure or temperature and enter the applied value in the Dead Weight / Tester Value field.
