Preface

Use of this Document This document provides a programmer with details on the P_DoseWSinstruction for a Logix-based controller. You should already be familiar withhow the Logix-based controller stores and processes data.

Novice programmers should read all the details about an instruction beforeusing the instruction. Experienced programmers can refer to the instructioninformation to verify details.

Conventions and RelatedTerms

Set and Clear

This manual uses set and clear to define the status of bits (booleans) and values(non-booleans):

This term: Means:

Set The bit is set to 1 (ON) A value is set to any non-zero number

Clear The bit is cleared to 0 (OFF) All the bits in a value are cleared to 0

Preface

Edge and Level

This manual uses Edge and Level to describe how bit (BOOL) Commands,Settings, Configurations, and Inputs to this instruction are sent by other logic

and processed by this instruction.

Send/Receive Method: Description:

Edge • Action is triggered by "rising edge" transition of input (0-1)

• Separate inputs are provided for complementary functions(such as "enable" and "disable")

• Sending logic SETS the bit (writes a 1) to initiate theaction; this instruction CLEARS the bit (to 0) immediately,then acts on the request, if possible

• Ladder Diagram (LD): use conditioned OTL (Latch) to send

• Structured Text (ST): use conditional assignment [if

(condition) then bit:=1;] to send• Function Block Diagram (FBD): OREF writes a 1 or 0 every

scan, should use Level, not Edge

Edge-triggering allows multiple senders per Command,Setting, Configuration, or Input (many-to-one relationship).

Level • Action ("enable") is triggered by input being at a level (in astate, usually 1)

• Opposite action ("disable") is triggered by input being inopposite state (0)

• Sending logic SETS the bit (writes a 1) or CLEARS the bit(writes a 0); this instruction does not change the bit

• LD: use OTE (Energize) to send

• ST: use unconditional assignment[bit:= expression_resulting_in_1_or_0;] or"if-then-else" logic [if (condition) then bit:= 1; else bit:= 0;]

• FBD: use OREF to the input bit

Level triggering allows only one sender to drive each Levelinput on the instruction (one-to-one relationship restriction).

IMPORTANT All Operator Commands (OCmd_) and Maintenance Commands(MCmd_) are Edge triggered. The HMI graphic object orFaceplate SETS (writes a 1 to) each Command bit and theInstruction CLEARS (writes a 0 to) the Command bit, then

performs the function, if possible.

Preface

Relay Ladder Rung Condition

The controller evaluates ladder instructions based on the rung conditionpreceding the instruction (rung-in condition). Based on the rung-in condition

and the instruction, the controller sets the rung condition following theinstruction (rung-out condition), which in turn, affects any subsequentinstruction.

If the rung-in condition to an input instruction is true, the controller evaluatesthe instruction and sets the rung-out condition based on the results of theinstruction. If the instruction evaluates to true, the rung-out condition is true;if the instruction evaluates to false, the rung-out condition is false.

IMPORTANT This instruction has Program Commands (PCmd_) which areselectable as Edge or Level, depending on the ConfigurationParameter Cfg_PCmdClear. If Cfg_PCmdClear is 1 (the default),all Program Commands are CLEARED when received (edge). If

Cfg_PCmdClear is 0, Program Commands as noted in theInstruction Data Reference become Level triggered, andopposite functions are triggered by the primary ProgramCommand being CLEARED to 0.

IMPORTANT The rung-in condition is reflected in the EnableIn parameter anddetermines how the system performs each Process Add-OnInstruction. If the EnableIn signal is TRUE, the system performsthe instruction’s main logic routine. Conversely, if the EnableInsignal is FALSE, the system performs the instruction’sEnableInFalse routine.

The instruction’s main logic routine sets/clears the EnableOutparameter, which then determines the rung-out condition. TheEnableInFalse routine cannot set the EnableOut parameter. Ifthe rung-in condition is FALSE, then the EnableOut parameterand the rung-out condition will also be FALSE.

Preface

Pre-Scan

During the transition into RUN, the controller performs a Pre-scan before thefirst logic scan. Pre-scan is a special scan of all routines in the controller. The

controller scans all main routines and subroutines during Pre-scan, but ignoresjumps that could skip the execution of instructions. The controller executes allFOR loops and subroutine calls. If a subroutine is called more than once, it isexecuted each time it is called. The controller uses Pre-scan instructions toreset non-retentive data values.

During Pre-scan, input values are not current and outputs are not written. Thefollowing conditions generate Pre-scan:

• toggle from Program to Run mode.

• automatically enter Run mode from a power-up condition.

Pre-scan does not occur for a program when:

• the program becomes scheduled while the controller is running.

• the program is unscheduled when the controller enters Run mode.

IMPORTANT The Pre-scan process performs the Process Add-On Instruction’slogic routine as all FALSE and then performs its Pre-scanroutine as TRUE.

Preface

Function Block States

The controller evaluates function block instructions based on the state ofdifferent conditions.

Every function block instruction also includes EnableIn and EnableOutparameters.

If the EnableIn parameter is not wired, the instruction always executes asnormal and EnableIn remains set. If you clear EnableIn, it changes to set thenext time the instruction executes.

Possible Condition: Description:

Pre-scan Pre-scan for function block routines is the same as for relayladder routines. The only difference is that the Enablelnparameter for each function block instruction is cleared duringPre-scan.

Instruction first scan Instruction first scan refers to the first time an instruction isexecuted after Pre-scan. The controller uses instruction firstscan to read current inputs and determine the appropriatestate to be in.

Instruction first run Instruction first run refers to the first time the instructionexecutes with a new instance of a data structure. The

controller uses instruction first run to generate coefficientsand other data stores that do not change for a function blockafter initial download.

IMPORTANT When programming in function block, restrict the rangeof engineering units to ±10±15 because internal floatingpoint calculations are done using single precision floatingpoint. Engineering units outside of this range may result ina loss of accuracy if results approach the limitations of

single precision floating point (±10±38 ).

Entering Text in FactoryTalk View SE

When entering data into String Input fields in FactoryTalk View SE, the data isnot saved to the tag until the user presses the Enter key. When the Input Field

is enabled, its border changes based on the state of the input:

• When the Input Field is Active (the cursor is in the field), the Input Field border is a

solid line.

• If the user modifies the data in the Input Field and moves to a different field without

pressing the Enter key, the border remains a solid line indicating that the data has not

been saved to the tag.

• If the data in the Input Field has not changed or has been written to the controller

tag, the border is a dashed line.

Chapter 1

Overview

The P_DoseWS (Weigh Scale Dosing) Add-On Instruction controls aningredient addition which uses a weigh scale to measure the amount ofingredient added. The weigh scale may be on the receiving vessel (gain in weight) or on the sourcing vessel (loss in weight). The weigh scale can beconnected via an analog input, device network or other connection.

Use when:

• You want to control basic dosing (ingredient addition) with basicfeatures such as bulk/dribble rate selection, Preact, automatic Preactadjustment, and the ability to start, pause and resume flow.

• You are measuring the amount of ingredient added to a destination vessel (gain in weight) or the amount transferred from a source vesselusing a weigh scale. The scale provides a weight value and can beinterfaced via an analog input card, network, or other means.

Do NOT use when:

• You measure the amount of ingredient transferred with a flowmeter.Use the P_DoseFM Instruction instead.

• You need to control precision blending. This instruction does notinclude capability for controlled-rate addition such as ratio control,digital blending or precision blending. Contact your Rockwell Automation representative for a blending solution.

• You only need a totalizer (integrator). Use the built-in TOT instructioninstead.

• You only need to display a weigh scales’s weight or generate high andlow weight alarms. Use the P_AIn analog Input Add-On Instructioninstead.

You may need additional logic when:

• You need more complicated sequencing, including special actions whenrestarting, aborting or holding an addition. This sort of sequencing is agood candidate for an Equipment Phase. Equipment Phase logic candrive the P_DoseWS instruction using its Program Mode commandsand settings.

Chapter 1 Overview

• The material transfer equipment requires complicated startup andshutdown logic. You can provide this logic separately and use theP_DoseWS outputs to trigger the logic for startup and shutdown ofingredient delivery.

Functional Description A typical sequence of Operator Commands and Settings and subsequentInstruction actions using the P_DoseWS instruction to perform ingredientdosing in Operator Mode is depicted in the figure on page 3.

Primary Operations The primary operations of the P_DoseWS Instruction are:

• Provides linear scaling of the input weight value from ‘raw’ (input card)units to ‘engineering’ (display) units.

• Uses a software ‘tare’ of the scale to establish the zero quantity startingpoint for transfer. Once the scale is tared, the instruction checks for‘unrequested’ flow, that is, an increase or decrease in scale weight beforeflow is actually started, and raises a Tare Fault alarm if such a weightchange occurs.

• Provides a rate of weight change calculation (differentiation with respectto time) to generate an inferred flow rate. The calculated rate is filteredand has a Low Cutoff, so the rate will be reported as zero when thechange in weight is only from noise on the input weight signal.

• Provides outputs to control associated equipment (pumps, valves, etc.)to start and stop flow. The Operator or the Program may start theingredient addition, then pause and resume as needed.

• Monitors the status of controlled equipment (pumps, valves, etc.). Flowis stopped and an alarm is raised on an equipment fault or if theequipment fails to respond as commanded.

• Monitors the Weight PV Input quality and communication status andprovides indication of Uncertain or Bad Weight PV. Flow is stopped andan alarm is raised on a Bad PV or communication loss.

• Provides Program or Operator entry of a Quantity to deliver (setpoint)and calculates the amount remaining to deliver and percent completeduring delivery.

Chapter 1 Overview

• Provides Program or Operator entry of High and Low Tolerance limits. Allows the Program or Operator to initiate a Tolerance Check afterdelivery is complete. Provides a warning if under tolerance and allowsthe Operator to ‘bump’ the flow to make up the shortage. The bumpcan be set up as a timed bump or as an operator ‘jog’-like function.Provides an alarm if over tolerance and inhibits further flow.

• Includes the ability to automatically switch to a lower dribble flow rateas the quantity delivered approaches setpoint. Provides Operator orProgram entry of the Dribble Quantity. Provides ‘run’, ‘dribble’ and‘stop’ outputs to controlled equipment.

• Uses a Preact value to stop flow to account for material in transit, timefor equipment to stop, and delays in measurement, scan,communication, etc. Provides Operator or Program entry of the Preact value. Provides an optional automatic Preact correction based on the

error in delivery when tolerance is checked. The auto correction allowsthe Preact to ‘learn’ the correct value over time.

• Uses the standard Mode (P_Mode) Instruction to provide Mode(ownership) for entry of limits and acceptance of commands. See theOperating Modes section for more information.

Operating Modes The P_DoseWS Instruction uses the following standard Modes, implementedusing an embedded P_Mode Add-On Instruction:

The Hand and Override (Ovrd) Modes are not used. (These Modes aretypically used by the controlled equipment.)

Alarm DescriptionOperator The Operator can enter settings for Setpoint, Preact, Dribble

Quantity, and High and Low Tolerances. The Operator can clear,start and stop the totalizer, start and stop (pause) ingredient flow,initiate the tolerance check, and bump flow if needed after additionstops at the Preact.

Program Program logic can set the Setpoint, Preact, Dribble Quantity, andHigh and Low Tolerances. Program logic can clear, start and stopthe totalizer, start and stop (pause) ingredient flow and initiate thetolerance check. The Operator can still bump flow if needed afteraddition stops at the Preact.

Maintenance Identical to Operator Mode, except for Mode priority rules:

• Program cannot acquire away from Maintenance, but Programcan acquire away from Operator if Operator Mode is not locked.

• Operator cannot acquire away from Program if Program Mode islocked, but Maintenance can acquire away from Program at anytime.

Refer to the Logix5000 Controllers Add-On Instructions ProgrammingManual, publication 1756-PM010, for more information on Add-OnInstruction execution condition handling.

Alarm Description

Over Tolerance Raised when Tolerance Check is performed if the quantity deliveredexceeds the setpoint by more than the high tolerance limit.

Under Tolerance(warning)

Raised when the Tolerance check is performed if the quantity deliveredfalls short of the setpoint by more than the low tolerance limit.

Equipment Fault Raised if the controlled equipment asserts the Inp_CtrldEqpFault inputor if the equipment feedback signals fail to track the commanded stateof the equipment. If configured as a shed fault, this also stops flow if it

is running.Tare Fault Raised if the scale is tared and then drifts away from the tare weight

before the start flow command is received.

Condition Description

EnableIn False (False Rung) Any commands received are discarded. Allalarms are cleared. The Mode is reported as‘NO MODE’. The displayed rate is zeroed.Outputs to controlled equipment arede-energized. Other output parameters(Values and Status) hold their last value.

Powerup (Pre-Scan, First Scan) Any Commands received before First Scanare discarded.

Embedded P_Alarm instructions arehandled in accordance with their standardpowerup procedures. Refer to theReference Manual for the P_Alarm

Instruction for more information.

Postscan (SFC Transition) No SFC Postscan logic is provided.

In normal operation, the Tare

command copies the currentscale weight (Val_PV) to theTare weight (Val_Tare).(Again, the tare and scale areequal and the deliveredquantity Val_Qty becomeszero.)

IMPORTANT

In Simulation, the Tarecommand will cause a“bump” in the weight PV

(Val_PV) as it is “reinitialized”to this Start Weight. To avoidthe bump, copy Val_PV toCfg_SimStartWt in your code.The purpose of this parameteris to make it easy for anoperator in training to runmany simulated transferswithout running thesimulated scale weightoutside the scaled range.

Operator Settings, Maintenance Settings, Other Settings

(OSet_, MSet_, Set_)

Operator, Maintenance and Other Setting data elements are used by the HMIFaceplate to let the operator establish setpoints, thresholds, and other settingsof the P_DoseWS Instruction. The P_DoseWS Instruction uses OtherSettings in its logic regardless of Mode. It uses Operator and MaintenanceSettings when it is in the Operator or Maintenance Mode.

Operator / Maintenance Setting Readies

Operator / Maintenance Setting Readies are used to enable (1) or gray-out (0)the Setting data entry fields on the HMI faceplate. Specific ready bits are usedfor certain Operator or Maintenance Settings. Rdy_OSet applies to allOperator or Maintenance Settings for which there are no specific Ready bits.

HMI Reference

This chapter describes the HMI Graphic Objects and Faceplates provided forthe Operator interface for the P_DoseWS Instruction.

Graphic Objects Graphic Objects are provided for use on end-user process graphic displays. Weigh Scale Dosing Graphic Objects have the following common attributes:

Each Weigh Scale Dosing Graphic Symbol displays the object’s label andengineering units text, the current value of the scale weight and quantitydelivered in this dosing, and various status indicators. The current values of thequantity and weight change color depending on the input signal quality. Thegraphic symbol has a color changing alarm border that blinks onunacknowledged alarm.

The overall Graphic Symbol includes a touch field over it which calls up theobject’s Faceplate. In addition, pausing the pointing device over the GraphicSymbol displays a tooltip showing the object’s configured Tag and Description.

Graphic Representation

The Weight Value and Quantity Value displays change color based on the

highest severity alarm currently active.

The color of the Weigh Scale symbol and its state text change depending on

the commanded state of the controlled equipment:

Status / Quality Indicators

One of these symbols appears to the left of the Weight Value when thedescribed condition is true

TIP

When the Invalid Configuration Indicator appears, you can find whatconfiguration setting is invalid by following the indicators like a ’trail ofbreadcrumbs’. Click the Graphic Symbol to call up the Faceplate. The InvalidConfiguration indicator will appear next to the appropriate tab at the top of theFaceplate to guide you in finding the configuration error. Once you navigate to thetab, the misconfigured item will be flagged with this indicator or appear in amagenta box.
