Introduction

The field-mount Vantageview Super Snoopers are serial input RS-485 Modbus Modbus devices are ideal for applications in need of a rugged solution. The Vantageview decimal version has a two-line decimal display. The Vantageview feet & inches version’s top line displays level in feet and inches up to 399 ft, 11 and 15/16 inches. It includes a 20-segment tank level indicator.

Each can accept up to 16 Modbus process variables (PVs), from up to 16 devices. The scanners automatically cycle through the PVs, with the ability to manually cycle PVs or pause scanning.

Up to four math channels (CV1-CV4) may be used to perform math functions on any of the input variables. Math functions include sum, difference, weighted average, ratio and more. Nested math functions may be used in these math equations, allowing for complex math functions.

The display is programmable to show any input, math channel, units, or tags, on a variety of display combinations between the top and bottom displays.

Standard features include SafeTouch through-window buttons for operating the scanner without removing the cover, a backlight that makes the display mode visible in any lighting condition, 511 points of input data logging, and two open collector pulse or alarm outputs. A 4-20 mA output is available as an option.

The enclosure has three threaded conduit holes, integrated pipe or wall mounting flanges, and allows for easy installation of tamper seals. Two conduit plugs are installed; additional plugs are available (part number PDAPLUG75P).

Free, PC-based, ScanView EX software that connects to the scanner via the PDA8068, PDA7485-I, or the

PDA8485-I is available for programming and setup of

the instrument.

The instrument can also be programmed using the four SafeTouch through-window buttons, without removing the cover, or with four internal push-buttons.

The PD6730X includes on-board data logging of up to 511 points.

Setup and Programming

Overview

Setup and programming is done through the infrared through-window SafeTouch buttons, using the mechanical buttons when uncovered, or with ScanView EX programming software. There are two slide switches located on the display module. One switch is used to lock or unlock the SafeTouch Buttons. The other switch is used to configure the pulse input (Refer to LIM6730XPulse for instructions).

ScanView EX Programming Software

The fastest and easiest way to program the meter is using the free ScanView EX programming software. This software greatly simplifies the programming process and allows the user to save configuration files for later use.

The ScanView EX software requires one of several options to connect to a PC depending on the PC’s hardware; The PDA8068

PDA7485-I RS-232 to RS-485 converter, or the PDA8485-I USB to RS-485 Isolated Converter to

connect the PC to the meter.

Instruction Manual

SafeTouch Buttons

The PD6730X is equipped with four sensors that operate as through-window buttons so that it can be programmed and operated without removing the cover (and exposing the electronics). These buttons can be disabled for security by using the THRUGLASS BUTTONS switch and selecting the OFF setting. This switch is located on the back of the removable electronics module.

SafeTouch Button Operation

To actuate a button, press and remove one finger to the window directly over the marked button area. Remove finger to at least 4 inches away from the window in between button activations. SafeTouch and mechanical buttons may be held to cycle through menus or digits in place of repeatedly pushing a button.

SafeTouch Power Save Mode

(Symbol shown on -2 decimal models only)

SafeTouch buttons enter a power saving mode after three minutes of inactivity. This mode is indicated by

a power symbol ( ) appearing in the lower right of the display. Only the MENU button is monitored in this mode. To activate the SafeTouch buttons, press and hold the menu button for up to five seconds. The display will read AWAKE, and the SafeTouch buttons will be fully enabled.

SafeTouch Disabled Mode When the cover is removed, the four mechanical

buttons located next to the sensors may be used. The sensors are disabled when a mechanical button is pressed and will automatically be re-enabled after 60 seconds of inactivity. The SafeTouch power

symbol ( ) will blink in the lower right of the display if the buttons are disabled due to a mechanical pushbutton being pressed.

SafeTouch Button Equalize Delay

The SafeTouch buttons are designed to constantly recalibrate for ambient conditions. When the cover position is changed, the cover is removed, or an object is removed that was placed over the front window, it may take a moment for the SafeTouch buttons to recalibrate to the change in conditions.

Allow up to 2 minutes for the SafeTouch buttons to recalibrate to new conditions in these cases where the cover position was changed, or the

SafeTouch Button Tips and Troubleshooting

The SafeTouch Buttons are designed to filter normal levels of ambient interference and to protect against false triggering, however it is recommended that the SafeTouch Buttons be turned off (slide THRU-GLASS BUTTONS switch to OFF) if there is an infrared interference source in line-of-sight to the display or if the buttons are not needed.

SafeTouch Button Tips:

• To the extent possible, install the display facing away from sunlight, windows, reflective objects, and any sources of infrared interference.

• Keep the window clean.

• Tighten the cover securely.

• Use a password to prevent tampering.

• If the cover has not been installed and secured

tightly, it may take a moment for the SafeTouch buttons to properly self-calibrate when the cover is tightened.

After all connections have been completed and verified, connect the ribbon cable to the display module, fasten the display module to the base, install enclosure cover, and then apply power.

Page 22

PD6730X Field-Mount Modbus Scanners

Master Mode (MASTER)

In Master mode, the scanner will poll up to 16 Modbus registers in up to 16 Modbus devices. It will serve as a Modbus network master; polling Modbus slave devices for Modbus process variables (PVs) that can be displayed or used in the math functions.

Programming the Modbus Master mode will include defining the Modbus PV registers and devices, selecting the polling time interval, and the maximum response time allowed.

Instruction Manual

PV Number Configuration (PV NUM)

The PV Number menu is used to enable and disable each Modbus PV 1 to PV 16. The Modbus device and registers are configured for each of the enabled PVs. PVs that are not enabled will not appear in other programming menus for display or inclusion in math channel functions (CV).

PV1 to PV16 are programmed using identical menus.

• To enable a PV it must be assigned to a specific slave ID.

Enable/Disable PV (ENABLE, DISABLE)

Enable or disable the Modbus PV. Disabled PVs will require no additional configuration. Disabled PVs will not be accessible in other menus or functions.

Instruction Manual

Poll Time (T POLL)

Enter the time between read command sequences. In other words, how often the display values are updated in Master mode. The poll time defines how often the device will begin scanning all enabled Modbus PVs. For example, if the Poll Time is two seconds, the scanner will begin polling all Modbus PVs every two seconds.

This parameter defines the approximate time between updates of a PV value. Communications errors may make updating a PV take longer.

Note: Depending on the Response Timeout, and the number of PV poll requests that time out, it may take more than one poll time to poll all enabled Modbus PVs. In this scenario, the scanner will begin another round of polling at the next poll time interval.

For example: Due to transmission errors, the scanner with a 2 second poll time requires 2.5 seconds to update all the Modbus PVs. It will begin the second polling of all the Modbus PVs at 4 seconds.

Note: In the feet and inches display models enter this value in the format XX.X seconds, but no decimal point is present in the display. For example: enter 20 for a poll time of 2.0 seconds.

Response Timeout (TIMEOUT)

Enter the time the scanner will wait after a request for information has been sent to a slave device before it will assume an error on that request. Increasing the timeout will help eliminate polling errors when polling slow devices. Increasing the response timeout will also slow the PV update rate in systems that are experiencing communications failures.

Note: The feet and inches display models enter this value in the format XX.X seconds, but no decimal point is present in the display. For example: enter 20 for a poll time of 2.0 seconds.

Retries Before Error (RETRIES)

Enter the number of consecutive failures to poll a device that will result in a communications error message on the display. This is the number of times a specific PV must be polled before the display indicates a communication failure rather than displaying the available PV data. Increasing this number will allow for more polling failures before a communication error is detected, which may be required for some unreliable networks. Increasing this number will also increase how long old data is displayed before a communication error is indicated.

Page 24

PD6730X Field-Mount Modbus Scanners

Slave Mode (SLAVE)

In Slave mode, a Modbus master may write up to 16 Modbus PVs to the scanner, which can then display and process the data in the PV Modbus registers, such as displaying the data and using them in math functions.

Programming the scanner for Modbus Slave mode will include defining the Modbus PV registers that are enabled, as well as selecting the time between data writes before an error is assumed. In Slave mode the scanner accepts floating point data (Byte order: 1234 big endian).

Instruction Manual

Enable/Disable PV (ENABLE, DISABLE)

Enable or disable the Modbus PV. Disabled PVs will require no additional configuration. Disabled PVs will not be accessible in other menus or functions.

The Slave mode accepts floating point data type (Byte order: 1234 big endian).

Slave Response Timeout (TIMEOUT)

If the Modbus data registers for the enabled Modbus PVs are not updated within a certain period of time, the scanner can presume that there is an error with the data, or that it is too out of date to be worth displaying. In this case, the scanner will display this PV as NONE (NONE).

At the Response Timeout menu, enter the time limit for the scanner to continue to display data written to the Modbus PV register. To disable this feature, and always display the last data written to the Modbus register regardless of how long ago the data was updated, set this value to 0 seconds.

PV Number Configuration (PV NUM)

The PV Number menu is used to enable and disable each Modbus PV 1 to 16. PVs that are not enabled will not appear in other programming menus for display or inclusion in math channel functions (CV). PV1 to PV16 are programmed in identical menus.

Page 25

PD6730X Field-Mount Modbus Scanners

Snooper Mode (SNOOPER)

In Snooper mode, the scanner will act as a Modbus network packet sniffer. The Snooper mode is used to listen to data being transmitted on the bus. Up to 16 process variables may be read from the RS-485 bus and displayed or used in math functions. The same process variables can be displayed in multiple locations.

Instruction Manual

Snooper Mode PV Configuration

(PV NUM)

The PV Number menu is used to enable and disable each Modbus PV 1 to PV 16. This menu is identical in Master mode. Refer to PV Number Configuration (PV NUM) on page 22.

Snooper Mode Response Time (T RESP)

If the Modbus data registers for the enabled Modbus PVs are not updated within a certain period of time, the scanner can presume that there is an error with the data. After this time has passed, and updated data has not been detected on the Modbus network, the scanner will display this PV as NONE (NONE).

At the Response Time menu, enter the time limit the scanner will display the Modbus PV register last data monitored before it assumes an error.

Notes:

The poll time for scanners set up for Snooper mode must be greater than the Master’s poll time. This setting corresponds to the time window during which the Snooper listens to the bus for a reply by the slave device being polled by the master device. As soon as the Snooper detects a new reply on the bus, the display is updated. If there is no reply within the Response Time setting, the Snooper goes into communications break condition.

To minimize the possibility of communication errors and communication break conditions, use a poll time of 5 seconds or more with slow baud rates (e.g. 4800 bps or less).

• If multiple registers are polled by the master with one command, only the first returned value will be read.

• To snoop multiple PVs, the master must request one PV at a time.

Instruction Manual

Scale Modbus PV to Engineering Units (SCALE)

The Modbus PVs may be scaled to reflect different engineering units than the data read out of the Modbus slave device register. To do this, use the Scale menu to select the type of scale desired.

Note 1: The bottom display of the feet and inches display models does not show decimal points. While the decimal point may not appear, it is included on the factor programming steps.

For example: To enter a conversion factor of 2.54, select a factor decimal point with 2 decimal locations, and enter a factor value of 254.

Note 2: MP-SCAL is only available when scaling PV1.

Page 30

PD6730X Field-Mount Modbus Scanners

Factor (FACTOR)

Factor scaling uses a conversion factor for scaling a number of PV register counts to a single display count. In other words, the factor acts as a multiplier to change Modbus PV register data units into display engineering units.

Factor Decimal Point (FACTR.DP)

Enter the number of decimal point locations necessary to enter the conversion factor.

Conversion Factor Value (VALUE)

Enter the conversion factor; the multiplier value that is applied to the Modbus PV register data to convert it to the desired display engineering units.

For example: if the PV register data is a height in centimeters, but a height in inches is desired on the display, a factor of 0.393701 would be entered.

(Display Value) = (Modbus Register Value) * (Factor)

Example: (386.08 cm) * (0.393701) = (152.00 in) = (12 ft 8 in)

Note: The bottom display of the feet and inches display models does not show decimal points. While the decimal point may not appear, it is included on the factor programming steps.

For example: if the PV register data is 0 to 100 in a flowmeter, but a flow rate desired on the display is 0 to 250 GPM, a factor of 2.5 would be entered. On feet and inches display models, there is no lower display decimal point. Therefore, a factor decimal point of 1 place is selected, and a conversion factor value of 25 is entered.

Instruction Manual

Linear (LINEAR)

Linear scaling is used to convert a linear scale of PV to display value.

Input Values 1 and 2 (INP)

Enter the Modbus PV register data for scaling points 1 and 2.

Display Values 1 and 2 (DSP)

Enter the corresponding display values for input points 1 and 2.

For example: If a PV register contains data in terms of tank height in feet for a 100 feet tank, the display value can be linearly scaled for an input of 0 feet (Input 1) displaying 0 percent (Display 1), and an input of 100 feet (Input 2) displaying as 100 percent (Display 2).

Not available on Modbus PVs assigned to the feet and inches display of feet and inches display models.

Multipoint Scaling (MP-SCAL)

This type of scaling is only available for PV1. Multipoint Scaling is used when multiple linear scaling points are required, such as round horizontal tanks or conical storage silos. Up to 32 linearization points may be entered, with linear scaling between each point.

Not available on Modbus PV1 if assigned to the feet and inches display of feet and inches display model.

Number of Points (NO PTS)

Enter number of linearization points. The default value is 2 points. For linear inputs requiring only 2 scale points, use Linear scaling.

Open Collector Outputs (OUTPUT)

The scanner is equipped with two NPN open collector outputs that may be set up for pulse outputs, alarms, timed pulses, or turned off.

Pulse outputs can be based on a Modbus PV value, or math channel value. Both outputs may be used to generate a quadrature output based on any pulse menu output type. An output test mode is also selectable to generate pulses at a constant programmable frequency.

Alarms are available based on a Modbus PV or math channel. The alarm status will show on the display even if the output is not wired. The outputs may also be forced on or off.

A timed pulse output generates constant pulses at a specified frequency and on time.

The output may be disabled by selecting Off.

Instruction Manual

Output 1 and 2 Setup (OUT 1, OUT 2)

The function of open collector output 1 and 2 is configured using the Off (OFF), Pulse (PULSE), Alarm (ALARM), and Timer (TIMER) menus detailed below.

In the Output 1 and 2 menus, use the Up button to scroll through the menu choices.

Press Enter to make a selection and proceed to the next menu.

See Setting Numeric Values on page 18 for more in- formation on programming numeric count, set, and reset value.

Pulse Output (PUlse)

Pulse outputs may be assigned to Modbus PV (PV), math channel (CV), quadrature (QUAD), or test (TEST).

menu only applicable to PV option.

Note 2: Refer to pulse input manual

Page 39

PD6730X Field-Mount Modbus Scanners

Note 1

Quadrature Pulse Output (QUAD)

The pulse output set to quadrature will duplicate the other open collector output, but lag by ¼ duty cycle (90 degrees out of phase). For example, Out 1 will follow Out 2, if Out 1 is set to QUAD. Only one output should be set to QUAD. If both outputs are set to QUAD, both outputs will be disabled. The other output should be programmed as desired for the quadrature output function, and must be a pulse (PUlse) output selection.

Test Pulse Output (test)

The test output setting programs the output to generate pulses at a programmed constant frequency. Set the frequency decimal point location in the DECPT menu, and then enter the desired output frequency in Hz in the PULSE menu.

Modbus PV or Math Pulse Output (PV)

The pulse output may be based on an enabled Modbus PV or math channels CV1 to CV4. The pulse output frequency in hertz (Hz) is calculated as the value of the selected PV or CV divided by the programmable count (or divisor).

The frequency of the pulse output will update as the PV or CV value is changed. For example, if the output is set to reference PV 2, and PV 2 is reading 1540.5, with a count or 10, the pulse output frequency will be 154.05 Hz.

Alarm Output (ALARM)

Alarm outputs may be assigned to Modbus PV or math channel (PV NUM), always on (ON) or always off (OFF).

Instruction Manual

Note 1: Refer to pulse input manual

Modbus PV or Math Alarm (PV NUM)

Program a PV (PV1-16) or math channel (CV1-4) to trigger an alarm. Select the source PV or CV for the alarm and enter the display value set and reset points. The alarm deadband is determined by the difference between set and reset points. Minimum deadband is one display count. If set and reset points are programmed the same, output will reset one count below set point.

Force On State (ON)

This alarm mode forces the output to be active, or on. This mode is primarily used to test alarm systems.

Force Off State (OFF)

This alarm mode forces the output to be inactive, or off. This mode is primarily used to test alarm systems.

Timer Output (TIMER)

The timer output produces a constant pulse width at a constant frequency. Program the Period (PERIOD) from 0.1 to 999999.9 seconds (time from the start of one pulse to the start of the next pulse).

Program the On Time (TIME) for the active low pulse from .01 to 99999.99 seconds (pulse width). The on time must be less than the delay time (Period).

Select Start (START) to begin outputting the constant timed pulse.

The above display examples show the date to be June 27, 2013; at 14 hours, 32 minutes, and 36 seconds.

The year, month, day, hour, and minute may all be set by the user. The real time clock will need to be reset if external power and battery power are lost.

To program the time, select the time or date component to be programmed, and press Enter. To enter the time or date as a numeric value, see Setting Numeric Values on page 18 for more information.

Changing the time (hours and minutes) will reset the second clock to 0.

Page 46

PD6730X Field-Mount Modbus Scanners

Data Log Setup (DATALOG)

The Data Log menu is used to setup and enable the data log functions. The scanner may contain up to 511 records, each containing the date, time, and log number. Each record may hold the first eight enabled Modbus PVs and all enabled math channel CVs.

The data log can hold 511 records of the first eight enabled Modbus PVs and math channel CVs.

The frequency of these records depends on the data log settings.

For example: If PV 1, 2, 3, and 4 are enabled, and CV 1 and 2 are enabled, the data log may record 511 logs containing PV 1, 2, 3, and 4, as well as CV 1 and CV 2. The data log will record these values even if CV2 is the only value set to display.

Instruction Manual

Log Time and Log Interval

There are two ways to configure the time when a data log record is recorded. The Log Time feature allows up to 4 data log events time to be entered for each day. The Log Interval feature allows a data log recording event at the selected time interval. At each data log event, all appropriate data records will be recorded.

Only the Log Time or Log Interval may be active at a time. While one type of data logging is enabled, the other menu is inaccessible.

Page 47

PD6730X Field-Mount Modbus Scanners

Log Time Setup (LOGTIME)

The Log Time menu contains four log events (LOG 1 to LOG 4). Each log time is configured independently. For each daily log time desired, enable a log, and set the log time for the hours and minutes the log is to be recorded. The time is set in real-time hours and minutes, based on the real time clock setup.

The Log Time feature will roll-over, deleting the oldest data logs (in blocks of 8) when the log is full and new logs must be recorded. This makes it the most useful for long-term data logging.

Interval Setup (INTERVL)

The Interval menu sets the time interval for data logging. Every time interval, one data log event will be recorded. To enable interval data logging, enable the feature, and set the interval time for the hours and minutes between each log.

If set to FULSTOP, the Log Interval feature will not de- lete old data, and data logging will stop when the log is full. This makes it the most useful for short periods and logging specific functions.

If set to CONT, the Log Interval feature will delete the old data when full and continue logging data. The Log Interval feature will roll-over, deleting the oldest data logs (in blocks of 8) when the log is full and new logs must be recorded. This makes it the most useful for long-term data logging.

View Data Log (LOGVIEW)

The Log View menu allows on-screen browsing of the data log event records stored in the scanner. Data points may be navigated by viewing the log number, date and time, first eight enabled PVs and four CVs. A known log may be jumped to immediately, avoiding a lengthy search for data. All logs may be deleted with the ERASE command, requiring confirmation.

Instruction Manual

Once the log records are displayed, use the Enter key to display variable within the same log and move to the next log. Use the Up and Right arrows to move to the next or previous log number.

Note 1: All enabled PVs and CVs will display in order, the Tag for each PV and CV will flash before displaying the value.

Note 2: All tags, values, and units will appear on the lower display with exception of feet and inches formatted values on the feet and inches display models. These parameters will automatically alternate on the display.

Backlight (BAKLITE)

The Backlight menu is used to enable or disable the backlight. After pressing Enter to access the Back-

light menu, press the Up arrow to Enable (ENABLE) or Disable (DISABLE) for the backlight.

Analog Output Calibration (AO CAL)

This feature is only used at the factory. It is not recommended to access this menu without instruction from technical support.

Page 48

PD6730X Field-Mount Modbus Scanners

Backup & Restore (BACKUP)

The scanner saves all parameter settings, and no reprogramming is necessary when power is lost and restored to the scanner.

These features are used to save and restore programmed settings. Programming can be restored to a known saved good configuration, or to factory defaults. This is useful to restore scanners whose programming has been altered in unknown ways, or to quickly restore known good settings if mistakes are made during reprogramming.

The Save feature (SAVE?) saves all current parameter settings into the memory of the backup restore. The backup restore feature is loaded with factory default settings until a new configuration is saved.

The Load feature (LOAD?) restores all parameters to the programmed values stored in backup restore memory. The Load feature will not affect the current password settings.

Instruction Manual

Information (INFO)

The Information menu is part of the System features menu. It shows software identification number, version number, and extended model number. To view this information:

Go to the Information menu (INFO) and press Enter button.

Continue pressing Enter to scroll through the displays.

Following the information display, the scanner will exit the Advanced features menu and return to run mode.

• Once scanner parameters have been saved to memory by the backup restore feature there is no recovering the previously saved settings.

• Once parameters have been loaded into the scanner from the backup restore feature there is no recovering the previously programmed settings.

The Default feature (DEFAULT) restores all parameters to the factory default values. Factory default reset does not change the saved backup restore settings, or override passwords.

In the Backup menu, use the Up arrow key to select the desired menu. Press Enter to execute the save, load, or restore defaults command. To restore the scanner to factory defaults, press Enter again to confirm the request when Defaults? (DEFLTS?) is

Troubleshooting

Due to the many features and functions of the scanner, it’s possible that the setup of the scanner does not agree with what an operator expects to see. If the scanner is not working as expected, refer to the Diagnostics menu and consult the recommendations described below.

Troubleshooting Tips

Symptom Check/Action

No display or faint display Check power connection.

Press and hold Menu key for 5 seconds to check for Standby mode. If “WAKEUP?” is displayed, press the Enter key to awaken the scanner from Standby mode.

SafeTouch Buttons do not respond

Scanner channel displays NONE

Long time between channel value updates

Scanner displays span error message during scaling

Scanner flashes maximum display

If the display locks up or the scanner does not respond

Backlight does not appear.

Other symptoms Call Technical Support for assistance.

If is displayed, hold Menu SafeTouch button to leave power save mode.

If is flashing, wait 60 seconds to leave mechanical pushbutton lockout mode. If the cover was recently tightly secured, you may need to wait up to 2 minutes for

buttons to self-calibrate to the new cover position due to window reflection. Verify THRU-GLASS BUTTONS switch on display module is in ON position. Sunlight can interfere with the sensors. It is recommended to shield the window

while operating the buttons by standing so as to block direct sunlight.

Verify that the polling parameters (slave address, register, etc) are correct. If the channel is a math channel CV, verify the chosen math function does not include any NONE selections or un-programmed Modbus PVs.

Verify all channels are communicating. Errors, combined with long timeouts and high allowable number of failures when polling Modbus devices, will combine to significantly delay the polling speed. Reduce the number of allowable timeout errors to check that communications are successful, and if there are errors, reduce the timeout if possible.

Verify minimum input span requirements

Check slave device registers are valid. Check math channels are not exceeding maximum possible display. Check input signal is within scaled range of 99999.

Perform hard reset by removing the display module or by removing DC power.

Backlight is intended for viewing assistance in dim lighting. It may not be noticeable under good lighting conditions.

Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory defaults and map changes ahead of time, rather than at random.
