Introduction

The PROVU

PD6080/6081 Super Snooper Modbus

digital scanner that can be programmed as a Modbus RTU Master, Slave, or Snooper. It is capable of scanning up to 16 variables generated by any Modbus device, which makes it ideal for tank level monitoring and control. Its superluminous LED digits make it easily readable in smoke, dust, fog, and, with the optional SunBright® display, even direct sunlight. The PD6080 displays in decimal format, while the PD6081 displays in Feet & Inches.

As a master, the PD6080/6081 reads up to 16 slave devices, scales the data from each, displays the result, and operates the internal relays and 4-20 mA output. The PD6080/6081 in Master mode is capable of polling up to 16 process variables (PVs); it displays all the enabled PVs in sequence, at a user programmable scan rate; it also allows other PD6080/6081s in Snooper mode to read any of the variables being polled by the master. As a snooper, the PD6080/6081 listens to the Modbus traffic and picks up a specific register or registers being polled by a master device from a specific slave device and processes the data being read. As a slave, it is controlled by a master device. The data sent to it by the master is scaled, displayed, and used to operate the relays and 4-20 mA output.

The PD6080/6081 Super Snooper is housed in a 1/8 DIN panel scanner enclosure that features a NEMA 4X front panel. Data is displayed on an adjustable intensity, dual-line, six-digit display. The upper display is a 0.6 inch, seven-segment LED display, while the lower display digit height is 0.46 inches. The Super Snooper can be powered from 85-265 VAC or 12-36 VDC. It is available with up to 4 internal relays and is available with 4 additional relays and up to 8 digital inputs/outputs, as well as a dual 4-20 mA output expansion module, as options.

The PD6080/6081 comes equipped with dual analog input channels (4-20 mA and/or 0-10 VDC) for use in Master Mode. These can be assigned to mA or volts by mapping a PV to the internal scanner addresses 256-259, depending on the desired function.

Various math functions may be applied to the Modbus and analog inputs including addition, difference, absolute difference, average, weighted average, multiplication, division, minimum, maximum, draw, ratio, and concentration. This is in addition to the signal input conditioning functions (linear, square root, programmable exponent, or round horizontal tank calculations). The displays, relays, and the analog outputs may be assigned to PVs or to math channels C1, C2, C3, or C4. The digital inputs/outputs can be custom-programmed for specific operations. A digital input (F4) is standard.

Free ScanView software allows a Super Snooper Modbus Scanner to be accessed with a computer. Configure multiple scanners, conveniently monitor critical information, and Datalog right from a PC with ease, further increasing plant efficiency.

Scanner is a multi-purpose, easy-to-use

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the following circuits for RC network assembly and installation:

Figure 11. AC and DC Loads Protection

Choose R and C as follows:

R: 0.5 to 1 Ω for each volt across the contacts C: 0.5 to 1 µF for each amp through closed contacts

Notes:

1. Use capacitors rated for 250 VAC.

2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.

3. Install the RC network at the scanner's relay screw terminals. An RC network may also be installed across the load. Experiment for best results.

Figure 12. Low Voltage DC Loads Protection

RC Networks Available from Precision Digital

RC networks are available from Precision Digital and should be applied to each relay contact switching an inductive load. Part number: PDX6901.

Note: Relays are de-rated to 1/14 HP (50 watts) with an inductive load.

Use a diode with a reverse breakdown voltage two to three times the circuit voltage and forward current at least as large as the load current.

The internal 24 VDC power supply powering the analog output may be used to power other devices, if the analog output is not used. The I+ terminal is the +24 V and the R terminal is the return.

External Relay, Analog Output, & Digital I/O Connections

The relay, analog out, and digital I/O expansion modules PDA1004, PDA1011, and PDA1044 are connected to the scanner using a CAT5 cable provided with each module. The two RJ45 connectors on the I/O expansion modules are identical and interchangeable; they are used to connect additional modules to the system. See LIM1044, Expansion Module Instruction Manual, for details.

Note: The jumper located between the RJ45 connectors of the PDA1044 must be removed on the second

digital I/O module in order for the system to recognize it as module #2.

Do not connect or disconnect the expansion modules with the power on!

Warning!

More detailed instructions are provided with each optional expansion module.

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as interlock relay(s). Interlock contact(s) are wired to digital input(s) and trigger the interlock relay. This feature is enabled by configuring the relay and relative digital input(s). In one example, dry interlock contacts are connected in series to one digital input which will be used to force on (energize) the assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O contact). See below.

Figure 14. Interlock Connections

Page 19

PROVU PD6080/PD6081 Modbus® Scanner Instruction Manual

Analog Input Signal Connections

Analog input signal connections are made to a nine-terminal connector labeled SIGNAL on the back of the scanner. The COM (common) terminals are the return for the 4-20 mA and the 10 V input signals. The two COM terminals connect to the same common return, and are not isolated.

Current and Voltage Connections

The following figures show examples of current and voltage connections. There are no switches or jumpers to set up for current and voltage inputs. Setup and programming is performed through the front panel buttons.

Figure 15. Transmitters Powered by Internal Supply

Figure 16. Transmitter Powered by Ext. Supply or Self-Powered

The current input is protected against current overload by a resettable fuse. The display may or may not show a fault condition depending on the nature of the overload. The fuse limits the current to a safe level when it detects a fault condition, and automatically resets itself when the fault condition is removed.

Figure 17. Voltage Input Connections

The scanner is capable of accepting any voltage from -10 VDC to +10 VDC.

ScanView Software

The meter can also be programmed using the PC-based ScanView software included with the meter. This software is can be installed on any Microsoft® Windows® (XP/Vista/7/8/10) computer by connecting to the meter’s onboard USB. The meter is powered by the USB connection, so there is no need to wire anything prior to programming the meter, though USB is intended only for meter configuration.

ScanView Installation

1. Connect one end of the provided USB cable to the meter and the other end to the computer.

The computer will automatically install the driver software it needs to talk to the meter.

Only one meter may be connected at a time. Attaching multiple meters will cause a conflict with the meter software.

2. Once the driver is installed, an AutoPlay dialog should appear

for the drive “MSINSTAL.” Click “Open folder to view files.” If the computer does not display an AutoPlay dialog for the drive “MSINSTAL,” you should open My Computer and doubleclick on the drive labeled “MSINSTAL.”

3. Double-click on the file named “MSStart.” The program will

open a few windows and install two programs on your computer. Simply follow the onscreen instructions until you see one of the dialogs below. If you receive a “User Account Control” warning, click “Yes.”

4. If there is an update available, click the “Update” button to

install the new version. Otherwise, click “Configure” to begin programming your meter.

Note: If you decide to update your ScanView installation, once the installation has completed, you will be asked if you want to update the installation files located on the meter itself. This way, you will always have the most current installation version on the meter for future installs.

 Do not unplug the meter while the new installation files are being written to it. The

meter will display notification once the process is complete.

Warning!

Monitoring and data logging for one scanner (Master mode) is available with ScanView software. All the enabled PVs and math channels may be logged to a single .csv file. The ScanView software synchronizes with the scanner in master mode one second after the scanner has completed a polling cycle. Additional information regarding configuration and monitoring of the meter using ScanView software is available online. Go to www.predig.com/ScanView.

Note: The poll time of the scanner must be greater than 5 seconds to prevent collisions on the bus.

 Do not disconnect and reconnect the meter rapidly. Allow at least 10 seconds from

disconnection before reconnecting USB to the meter.

Serial Communications (serial)

The scanner is equipped with RS-485 Modbus RTU serial communications. The Serial menu is used for programming the Scanner ID, Baud Rate, Transmit Delay, Parity, and Byte-to-

Byte Timeout parameters. To communicate with a computer or other data terminal equipment, an RS-485 to USB or RS-485 to RS-232

converter is required; see Ordering Information on page 6 for details.

Do not connect any equipment other than Precision Digital’s expansion

Warning!

When using more than one scanner in a multi-drop mode, each scanner must be provided with its own unique address. The scanner address (Scan ID) may be programmed between 1 and 247.

The transmit delay may be set between 0 and 4999 ms; this value must be less than (Poll Time/# of PVs). The parity can be set to even, odd, or none with 1 or 2 stop bits. Changes made to the Serial menu are initialized after exiting the Serial menu.

modules, cables, or scanners to the RJ45 M-LINK connector. Otherwise damage will occur to the equipment and the scanner.

Baud Rate for the PD6080/PD6081 is entered here by user, and must match that of other system devices. Choices are seen below.

When setting up the scanner to run on a Modbus system, the devices must be programmed with matching Baud Rate and Parity. Failure to match up the network devices’ parameters may result in communication breaks.

Notes:

1. The byte-to-byte timeout setting may be adjusted to fix communication errors with slow devices.

2. The Transmit Delay of the Master must be greater than the Snooper or the slave devices being

polled.

Scanner Mode Selection

Operating Modes (nmode)

The Mode menu is used to select how the scanner is to function:

1. Master: Reads a slave device, scales the data from it, displays the result, and operates the relays

and 4-20 mA output. The Master polls from 1 to 16 process variables from 1 to 16 slave devices. The Master processes and displays PV1 through PV16 and alternately displays the variables being polled.

2. Snooper: Listens to the Modbus traffic and picks up a specific register or registers being polled by

a Master device from a specific slave device and processes the data being read.

3. Slave: Read and controlled by a master device (PLC, DCS, etc). The data sent to it by the master

is scaled, displayed, and used to operate the relays and 4-20 mA output.

The Master mode requires additional parameter selection to specify how the slave device is to be read and how to interpret the data.

Press Menu to enter Scanner Programming. Press the Enter button to access any menu or press Up arrow button to scroll through choices. Press the Menu button to exit at any time and return to Run mode.

How to Enable Process Variables (PVs)

In Master or Snooper Mode, navigate to the PV Number menu and press ENTER. From there, the user can scroll through all of the sixteen available PVs. In order to enable a specific PV, simply press ENTER to access the desired PV, then scroll to ENABLE and press ENTER (Follow the same course of action for disabling PVs).

Enter the Slave ID of the device being polled by the Master, followed by the Function Code, Register Number, Data Type, and Byte Order. Analog input channels must be assigned a Slave ID corresponding to the input to be read as indicated here: Ch A = 256 (mA) or 257 (V), Ch B = 258 (mA) or 259 (V).

Once the desired PVs are enabled, navigate to the Setup menu and enter the PV Setup in order to select the PV tag, units, format, and decimal point parameters, as well as to scale the PVs.

Once the user has scaled the final PV, the scanner automatically goes to the Display Setup menu to access line 1 and 2 display assignments.

By default, display line 1 is assigned to Display PV (d pv) and line 2 to display the Tag (d tag) for the corresponding PV.

It is possible to display PVs & Tags on line 1 and 2 simultaneously by selecting Tag & PV Number (tag.pvn). Display line 1 is setup by default to display PV & tag for PV1, 3, 5, 7; while line 2 is setup by default to display PV & tag 2, 4, 6, 8. These can be changed by the user to display any or all PVs. Program either display line 1 or 2 to show the desired parameters and press ENTER. See page 34 for details.

Notes:

1. 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).

2. The response 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.

How to Select 5 or 6-Digit Registers

In Master or Snooper Mode, it is possible to select either a five-digit or a six-digit Register Number. Once the operator has enabled a PV, entered a Slave ID, and chosen a Function Code, the scanner will arrive at the Register Number menu (reg.nbr). Press the Right arrow to display and then the Up arrow to change the setting for the number of digits used for the Register Number (5 dig or 6 dig), then press ENTER.

Notes:

1. If Function Code 03 is selected, the Register Number defaults to 40001; if Function Code 04 is

selected, the Register Number defaults to 30001.

2. Default Data Type is Float

3. Default Slave ID for PV1=001, for PV2=002, for PV3=003, etc.

Short Long

The Master ignores the decimal point setting for slave devices that specify a Short or Long integer. For example, a slave that is displaying 12.34 is read as 1,234. Floating point data may or may not utilize the decimal point. Refer to the slave’s operating manual to make sure.

The Register Number range is based on the Function Code and the number of digits selected. See the following table:

Function Code 5 Digit 6 Digit

03 40001 – 49999 400001 – 465536

04 30001 – 39999 300001 – 365536

Setting the Display Decimal Point (disp.dp)

Decimal point may be set one to five decimal places or with no decimal point at all. Pressing the Up arrow moves the decimal point one place to the right until no decimal point is displayed, and then it moves to the leftmost position. The decimal point is programmable only for the Display Value.

Setting the Float Decimal Point (Flot..dp)

If floating point data type is selected, select the number of decimals to correspond to the expected floating point data; the numbers to right of the LSD will be ignored by the scanner.

Example: If you have a number such as 12.3456, you have to tell the scanner how many digits to the right are of interest to you. In this case selecting 4 places will make use of all the digits. For most applications the display decimal point will be set accordingly (i.e. 4 places). If 2 decimal places are selected, the number 12.3456 is displayed as 12.35; notice that the number is rounded up.

Page 33

PROVU PD6080/PD6081 Modbus® Scanner Instruction Manual

Scaling the PV Display Values (sCale)

The data that the scanner receives can be scaled to display in engineering units. Input 1 must be less than Input 2, Input 2 must be less than Input 3, etc. (known as monotonic values). Press Enter to save the changes or Menu to exit without saving. When the Linear function is selected for PV1 & PV2, up to 32 points may be programmed to handle non-linear data. Only two points are available for all other PVs and for either the Square Root or Programmable Exponent functions. Round Horizontal Tanks are scaled using the length and diameter of the tank.

Scale Menu

The display will show Error if the scaling or calibration process is unsuccessful. Undesired operation may occur if the error is not corrected. Correct the error by either changing one of the inputs in question or changing the number of points to exclude an erroneous input point.

Note 1: For Feet & Inches Display format, the display values will be in the format 99

Make the left digit for inches and 16 Inches, and 8/16 will be displayed as 50

blank if the value is less than 10. Example: 50 Feet, 9

_9 IN _8

instead of 50 FT 09 IN 08

11 IN 15

/16th

or 8th.

Note 2: Scaling Short and Long input values (input 1, input 2, etc.) should be done without the decimal

point.

Multi-Point Linearization (Linear)

The scanner is set up at the factory for 2-point linear scaling. Up to 32 linearization points may be selected for PV1 and PV2. All other PVs have two linearization points available. See page 58 for details.

Programming Set (set) & Reset (rst) Points

High alarm indication: program set point above reset point. Low alarm indication: program set point below reset point. The deadband is defined as the difference between set and reset points. Minimum deadband is one display count. If the set and reset points are programmed with the same value, the relay will reset one count below the set point.

Note: Changes are not saved until the reset point has been accepted.

Setting Fail-Safe Operation (failsf)

In fail-safe mode of operation, the relay coil is energized when the process variable is within safe limits and the relay coil is de-energized when the alarm condition exists. The fail-safe operation is set independently for each relay. Select on to enable or select off to disable fail-safe operation.

Programming Time Delay (delay)

The On and Off time delays may be programmed for each relay between 0 and 999.9 seconds. The relays will transfer only after the condition has been maintained for the corresponding time delay.

The On time delay is associated with the set point. The Off time delay is associated with the reset point.

Page 43

PROVU PD6080/PD6081 Modbus® Scanner Instruction Manual

Relay Action for Communications Break (break)

The Scanner will poll the slave device three times before reporting a communications break condition. After the third failure, the Response Timeout timer starts and will determine the actual time to report a PV in break condition.

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. No Action (The relays will maintain the last condition)

Relay Action for Loss of 4-20 mA Input (Loop Break)

The loop break feature is associated with the 4-20 mA input. Each relay may be programmed to go to one of the above conditions when the scanner detects the loss of the input signal (i.e. < 0.005 mA).

Notes:

1. This is not dependent on the Communications Break or Response Timeout setting.

2. This is not a true loop break condition; if the signal drops below 0.005 mA, it is interpreted as a “loop break” condition.

Relay and Alarm Operation Diagrams

The following graphs illustrate the operation of the relays, status LEDs, and ACK button.

High Alarm Operation (Set > Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To detect a new alarm condition, the signal must go below the set point, and then go above it.

Low Alarm Operation (Set < Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. For relay to turn back "on", signal must go above set point, and then go below it.

When the signal crosses the set point, the relay trips and the sample time starts. After the sample time has elapsed, the relay resets. The cycle repeats every time the set point is crossed, going up for high alarms and going down for low alarms.

The sample time can be programmed between 0.1 and 5999.9 seconds.

Relay Operation After Communications Break

When a Master scanner fails to receive a reply from the slave it is called a Communications Break. The relays can be programmed to react to this event by going On, Off, or No Action. After communication is restored the relays are turned off or on, based on their operating mode and their set and reset points, without regard to their prior state. This is similar to the auto initialization on power up. Below is a diagram showing three examples.

The same is true for a scanner set up to operate in Snooper mode.

When the scanner detects a break in the 4-20 mA loop, the relay will go to one of the following selected actions:

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. No action (no Act) (Processed as a low signal condition)

off on

Loop Break = Ignore

Loop Break = Off

Loop Break = On

Time Delay Operation

The following graphs show the operation of the time delay function.

When the signal crosses the set point, the On time delay timer starts and the relay trips when the time delay has elapsed. If the signal drops below the set point (high alarm) before the time delay has elapsed, the On time delay timer resets and the relay does not change state. The same principle applies to the Off time delay.

Note: If “Automatic or Manual (A-mAn)” reset mode is selected, the LED follows the reset point and not

the relay state when the relay is acknowledged.

Relay Operation Details

Overview

The relay capabilities of the scanner expand its usefulness beyond simple indication to provide users with alarm and control functions. These capabilities include front panel alarm status LEDs, as well as either 2 or 4 optional internal relays, and/or 4 external relays via expansion modules. Typical applications include high or low temperature, level, pressure or flow alarms, control applications such as simple on/off pump control, and pump alternation control for up to 8 pumps. There are four basic ways the relays can be used:

1. High or Low Alarms with Latching or Non-Latching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Pump Alternation Control for up to 8 Pumps

Relays Auto Initialization

When power is applied to the scanner, the front panel LEDs and alarm relays will reflect the state of the input to the scanner after the first response from the slave device. The following table indicates how the alarm LEDs and relays will react on power-up based on the set and reset points:

Front Panel LEDs

The LEDs on the front panel provide status indication for the following:

The scanner is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication. The LEDs are controlled by the set and reset points programmed by the user. When the display reaches a set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching relays.

For non-latching relays, the LED is always off during normal condition and always on during alarm condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).

For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge button (Default: F3 key assigned to ACK):

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching (automatic reset) operation.

The On and Off terminology does not refer to the status of the relay’s coil, which depends on the fail-safe mode selected.

Relay terminology for following tables

Terminology Relay Condition

On Alarm (Tripped) Off Normal (Reset)

Ack Acknowledged

Warning!

In latching relay mode, latched relays will reset (unlatch) when power is cycled.

Non-Latching Relay (Auto)

In this application, the scanner is set up for automatic reset (non-latching relay). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm finally goes away, the relay automatically resets and the LED also goes off.

Non-Latching Relay (A-man)

In this application, the scanner is set up for automatic and manual reset at any time (non-latching relay). The LED and the relay automatically reset when the scanner returns to the normal condition. The next time an alarm occurs, the operator acknowledges the alarm manually while the alarm condition still exists. This causes the relay to reset, but the LED stays on until the scanner returns to the normal condition.

Latching Relay (LatcH)

In this application, the scanner is set up for manual reset at any time. Acknowledging the alarm even if the alarm condition is still present resets the relay and turns off the LED.

Automatic reset only

Latching Relay (Lt-Clr)

In this application, the scanner is set up for manual reset only after the signal passes the reset point (alarm condition has cleared). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm is acknowledged after it returns to the normal state, the LED and the relay go off. Notice that the LED remains on, even after the scanner returns to the normal condition. This is because, for latching relays, the alarm LED reflects the status of the relay, regardless of the alarm condition.

Acknowledging Relays

There are two ways to acknowledge relays programmed for manual reset:

1. Via the programmable F4 digital input assigned to ACK (Default) and connected to a normally open pushbutton wired across F4 and COM.

2. Remotely via a normally open pushbutton wired across one of the digital inputs and the +5 V terminals on the digital I/O modules, which is triggered with a contact closure to COM, or with an active low signal (see page8).

When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.

Pump Alternation Control Applications (Altern)

For pump control applications where two or more similar pumps are used to control the level of a tank or a well, it is desirable to have all the pumps operate alternately. This prevents excessive wear and overheating of one pump over the lack of use of the other pumps.

Up to 8 relays can be set up to alternate every time an on/off pump cycle is completed. The set points and reset points can be programmed, so that the first pump on is the first pump off.

Application #1: Pump Alternation Using Relays 1 & 2

1. Relays 1 and 2 are set up for pump alternation.

2. Relays 3 and 4 are set up for low and high alarm indication.

1. Pump #1 turns on when the level reaches 30.000, when level drops below 10.000 pump #1 turns off.

2. The next time the level reaches 30.000, pump #2 turns on, when the level drops below 10.000, pump #2 turns off.

3. If the level doesn’t reach 35.000 pump #1 and pump #2 will be operating alternately.

4. If pump #1 cannot keep the level below 35.000 pump #2 will turn on at 35.000, then as the level drops to 10.000 pump #1 turns off, pump #2 is still running and shuts off below 5.000.

5. Notice that with the set and reset points of pump #2 outside the range of pump #1, the first pump on is the first pump to go off. This is true for up to 8 alternating pumps, if set up accordingly.

6. Relay #3 will go into alarm if the level drops below 4.000 and relay #4 will go into alarm if the level exceeds 40.000.

7. Adding the 4 external relays expansion module allows using the 4 SPDT internal relays for pump alternation and the 4 SPST external relays for high, high-high, low, and low-low alarm indication.

Setting Up the Interlock Relay (Force On) Feature

Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:

1. Access the Setup – Relay – Action menu and set the action to off.

2. In the Advanced features – User menu, program any of the digital inputs to Force On any of the

internal relays (1-4). The Advanced Features Menu can be found on page 53.

3. Connect a switch or dry contact between the +5V terminal and the corresponding digital input (dI-1 to

dI-4) terminal.

Interlock Relay Operation Example

Relays 1 & 2 are configured to energize (their front panel LEDs are off) when SW1 & SW2 switches (above) are closed. If the contacts to these digital inputs are opened, the corresponding front panel LEDs flash, indicating this condition. The processes being controlled by the interlock relay will stop, and will re-start only after the interlock relay is re-activated by the digital inputs (switches).

Note: If multiple digital inputs are assigned to the same relay, then the corresponding logic is (AND) – i.e. both switches must be closed to trip the relay.

Scaling the 4-20 mA Analog Output (Aout)

The 4-20 mA analog outputs can be scaled to provide a 4-20 mA signal for any display range selected. The Analog Outputs can be mapped to PVs or Math Channels. To select the channel and source assignments the analog outputs are assigned to, see Analog Output Source Programming on page 66.

No equipment is needed to scale the analog outputs; simply program the display values to the corresponding mA output signal.

The Analog Output menu is used to program the 4-20 mA outputs based on display values.

There are three analog outputs available. These only display when they are enabled. See graphic below.

Notes: Changes to the settings are saved to memory only after pressing ENTER. Changes made to settings prior to pressing ENTER are not saved. Once ENTER is pressed, the display moves to the next menu.

Scan Function (SCan)

The Scan menu is used to program the PV scan mode and the scanner’s behavior on alarm condition. The operator is able to scan automatically based on a time parameter, or scan manually with front panel keys or digital inputs. The operator is also able to set the scanner to stop on alarm or continue scanning on alarm. To resume scanning the operator must press the Next or Previous button. Please follow the menu below for details. In the Stop on Alarm mode, the scanner will go to the alarmed PV and remain there until the operator manually advances to the next PV or returns to the previous PV. If a new alarm is detected the process is repeated. The scanner ignores old alarms.

Continues

Control Menu.

Control Menu (Contrl)

The Control menu is used to control the 4-20 mA analog output and the relays manually, ignoring the input. Each relay and analog output can be programmed independently for manual control. Selecting automatic control sets all relays and analog output for automatic operation.

Once Manual mode is initiated on any relay or

analog output, an LED labeled “M” is turned

on. Every few seconds, all LEDs re presenting

outputs that are in Manua l mode, as well as

the “M” LED flash. This process will continue

as long as any output is in manual mode.

Noise Filter (filter)

Most applications do not require changing this parameter. It is intended to help attain a steady display with unsteady (noisy) input data. The field selectable noise filter averages any minor or quick changes in the input data and displays the reading with greater stability. Increasing the filter value will help stabilize the display. However, this will reduce the display response to changes on the input data. The filter level may be set anywhere from 2 to 199. Setting the filter value to zero disables the filter function, and the bypass setting becomes irrelevant. This parameter is associated with the analog input channels.

Noise Filter Bypass (bypass)

The scanner can be programmed to filter small input changes, but allow larger input changes to be displayed immediately, by setting the bypass value accordingly. If the input signal goes beyond the bypass value, it will be displayed immediately with no averaging done on it. The noise filter bypass value may be set anywhere from 0.2 to 99.9. Increasing the bypass value may slow down the display response to changes on the input signal. This parameter is associated with the analog input channels.

Rounding Feature (round)

The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used in addition to the filter function. Rounding causes the display to round to the nearest value according to the rounding criteria selected by the user. This setting affects the last three digits, regardless of decimal point position.

Select Menu (SELect)

The Select menu is used to select the input data linearization function (linear, square root, programmable exponent, or round horizontal tank), math functions, constants, low-flow cutoff, and analog output programming. Multi-point linearization is part of the linear function selection.

Page 58

PROVU PD6080/PD6081 Modbus® Scanner Meter Instruction Manual

Input Data Conditioning Function Menu (Functn)

The Function menu is used to select the input-to-output transfer function applied to the input data: linear, square root, programmable exponent, or round horizontal tank volume calculation. Multi-point linearization (for PV1 and PV2) is part of the linear function selection. Scanners are set up at the factory for linear function with 2-point linearization. The linear function provides a display that is linear with respect to the input data (e.g 0.000 = 0.000, 10.000 = 10.000, and then 5.000 = 5.000).

Linear Function Menu (Linear)

Scanners are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be selected for PV1 and PV2 under the Linear function in the Advanced Features menu. The multipoint linearization can be used to linearize the display for non-linear signals such as those from level transmitters used to measure volume in odd-shaped tanks or to convert level to flow using weirs and flumes with complex exponents.

Note: Multi-point Linearization applies to PV1 and PV2 only. All other PVs use two linearization points.

Page 59

PROVU PD6080/PD6081 Modbus® Scanner Instruction Manual

Square Root Function Menu (Square)

The square root function is used to calculate flow measured with a differential pressure transmitter. The flow rate is proportional to the square root of the differential pressure. Scale the scanner so that the low input signal (e.g. 4 mA) is equal to zero flow and the high input signal (e.g. 20 mA) is equal to the maximum flow.

Programmable Exponent Function Menu (prog e)

The programmable exponent function is used to calculate open-channel flow measured with a level transmitter in weirs and flumes. The flow rate is proportional to the head height. Scale the scanner so that the low input signal (e.g. 4 mA) is equal to zero flow and the high input signal (e.g. 20 mA) is equal to the maximum flow. This method works well for all weirs and flumes that have a simple exponent in the flow calculation formula. For weirs and flumes with complex exponents it is necessary to use a strapping table and the 32-point linearization of the scanner.

Round Horizontal Tank Function Menu (rht)

This function is used to calculate volume in a round horizontal tank with flat ends. The volume is calculated based on the diameter and length of the tank. The tank’s dimensions can be entered in inches or centimeters; the scanner automatically calculates the volume in gallons or liters. After entering the dimensions, complete the scaling process with the display values calculated by the scanner. The scanner can be re-scaled to display the volume in any engineering unit without the need to re-enter the dimensions again.

Changing the Volume from Gallons to Liters

In the graphic, entering the 48" for the diameter and 120" for the length of the round horizontal tank, the scanner automatically calculates that the volume of the tank is

940.02 gallons.

1. Convert gallons to liters

1 US gallon = 3.7854 L

940.02 gal = 3558.4 L

2. Go to the Setup - PV - Decimal Point menu and

change the decimal point to 1 decimal.

3. Go to the Setup - PV - Scale menu and press Enter

until dis 2 is shown on display line 1.

4. Press Enter and change the display 2 value to

3558.4.

5. The scanner is now displaying the volume in liters.

Note: The display can be scaled to display the volume in

any engineering units.

Math Functions (math)

The Math menu is used to select the math function that will determine the channels’ C1-C4 value. These math functions are applied to PVs and other math channels. The results are displayed by selecting Display Channel C (d Ch C) in the Display menu. Most math functions may be applied to all PVs: For example, it is possible to add up to 16 PVs and calculate the total volume of all the tanks in a field. The Math2 function allows for further calculations on the results of other math channels (e.g. C4 = C2/C1).

The following math functions are available:

4-20 mA Output Calibration

 There is no need to recalibrate the 4-20 mA output

when first received from the factory.

 The 4-20 mA outputs is factory calibrated prior to

shipment. The calibration equipment is certified to NIST standards.

CAUTION!

If an uncalibrated meter or a meter with less resolution is used, the calibration of the

4-20 mA output could be adversely affected.

4-20 mA Output Calibration Procedure

1. Wire the PD6080/6081 4-20 mA output to a current loop that includes a power supply (internal or external 12 to 24 VDC), and the mA input on the digital meter. See page 18 for details.

2. Turn on all devices. Allow for a 15 to 30 minute warm-up.

3. Go to the Advanced Features menu, and navigate to the Analog Output Programming (AoutPr)/Calibration (Calib) menu and press Enter.

4. The display will show 4 nmA. The PD6080/6081 mA output should now be close to 4 mA. Press Enter and the display will show 04.000. Enter the actual value read by the digital mA meter and press Enter.

5. The display will show 20 nmA. The PD6080/6081 mA output should now be close to 20 mA. Press Enter and the display will show 20.000. Enter the actual value read by the digital mA meter and press Enter.

6. The PD6080/6081 will now calculate the calibration factors and store them.

7. Press Menu to exit and return to Run mode.

The 4-20 mA output can be recalibrated in the field. A calibrated digital meter with an input range of at least 25 mA and a resolution of 1 μA is recommended.

Scanner Operation

The PD6080/6081 scanner is capable of operating as a Modbus Master, Slave or Snooper. As a Slave, the PD6080/6081 requires connection to a Master device: PLC, DCS, etc. As a Master, the PD6080/6081 interfaces up to sixteen slave devices and can alternately display their Process Variables. As a Snooper it can be connected anywhere in the RS-485 bus to read any of the variables being requested by the Master device.

Four math channels (C1-C4) are available to perform operations on any PV or math channel, with adder and factor constants, and display the results. Engineering units or tags may be displayed with all PVs or math channels. Another level of Math functions can be performed on the resultant math channel Math2. For example, the operator can use the Math2 Channel to calculate the Sum of all other Math Channels, which may have each performed a different Math function.

The dual-line display can be customized by the user. Typically, the upper display is used to display the PV, while the lower display is used to display the tag for each PV.

Additionally, the scanner can be set up to display any input or math channel on the upper display and alternate between tag & units on the lower display. The relays and analog output can be programmed to operate based on any PV or math channel.

The scanner is capable of accepting two analog input channels (A and B) of either current (0-20 mA, 4-20 mA) or voltage signals (0-5 V, 1-5 V, 0-10 V,  10 V) and displaying these signals in engineering units from -99999 to 999999 (e.g. a 4-20 mA signal could be displayed as -50.000 to 50.000). The analog input channels must be mapped to PVs using the IDs 256-259.

F4 Operation

A digital input, F4, is standard on the scanner. This digital input is programmed identically to function keys F1, F2, and F3. The input is triggered with a contact closure to COM, or with an active low signal. During operation, F4 operates according to the way is has been programmed in the Advanced Features – User menu. See page 67 for details.

Maximum/Minimum Readings

The max & min readings (peak & valley) reached by the PVs or math channels can be displayed by assigning the display to max/min through the Display Setup menu.

A digital input should be programmed to reset the max & min readings.
