Introduction

This manual is divided in three parts:

1. Ladder Logic: We describe control elements of a cont rol str ategy available in the LOGICVIEW and
used by the DF65.

2. Function Blo cks: We pr esent detailed descriptions of all function blocks available in the LOGICVIEW

Introduction

and used by the DF65.

3. LOGICVIEW: We describe Smar’s Soft ware LOGI CV IEW. This is the application used to c onfigure the
hardware of a contr ol system ( I/ O Modules, Power Supplies, CPU, et c), implement ladder logic
(includi ng ladder network elements and function bloc k s)

We suggest user to read i nitially chapters 1 and 2 and next going to chapter 3 that describes clearly how
to implement elements described in the first two chapter s. However, user is free to start reading from
chapter 3 pri or to the ot her ones and consult chapters 1 and 2 any time it is necessary. Chapter 3 deals
with description of the Smar’s LOGICVIEW Software that is part of the DF65 System.

This manual has practical examples that describe step- to-step how to set strategies of control. These
examples were incl uded in order to make easier user’s understanding of the system. These applications
are distri buted along this manual.

DF65 – LogicView Configuration Manual

NOTE

This document is a description of all function blocks and logic elem ents (ladder) implemented in the coprocessor
(DF65). Besides this document presents a description of how to configure and edit ladder networks through Smar’s
LOGICVIEW. This document also describes details of this software.

Smar reserves it the right to change any part of this manual without prior notice.
Note that different versions of the DF65 have different types of data, function blocks and generi c characteristics. The

last version of the DF65 is always an update of the old manual without prior notice. It means it will have all
characteristics included, old and new ones.

NETWORK ELEMENTS (LADDER
ELEMENTS) A ND TOOLS

This section will help you to understand the meaning of the network ladder elements and the
network tools.

The Network Elements

As mentioned before, LOGIC VIEW uses symbols and notations defined in the standard IEC-61131-

3.

Fig 1.1 - Network Tool Box.

Definitions of the Elements of the Network Tool Box

Normally Open Contact

The state of the left link is copied to the right link if the state of the associated Boolean variable
indicated by "LABEL " is ON. Otherwis e, th e state of the right li n k is OFF.

Normally Closed Contact

The state of the left link is copied to the right link if the state of the associated Boolean variable is
OFF. Otherwi se, th e state o f the r ight link is OFF.

Positive Transition-Sensing Contact

The state of the right link is ON from one evaluation of this element to the next when a transition of
the a ss oci at ed v ari abl e fr om OFF to ON is s ens ed a t th e sam e ti m e that th e st ate o f t he l eft li nk i s
ON. The state of the ri ght li nk will be OFF at all other ti mes.

Negative T ransition-Sensing Contact

The state of the right link is ON from one evaluation of this element to the next when a transition of
the a ss oci ated va ri abl e fr om ON to OF F i s sens ed a t t he sam e ti m e the s tat e of th e lef t li nk is O N.
The s tate o f the right l ink will be OFF at al l other times.

1.1

Ladder Elements

Coil

The s tate o f the left link is copied to the asso ciated Boolean variable and t o the right link.

Negated Coil

The state of the left link is copied to the right link. The inverse of the state of the left link is copied to
the associated Boolean variable, that is, if the state of the left link is OFF, then the state of the
associated variable is ON, and vice versa.

Set (Latch) Coil

The a ssoci ated B oolea n vari able i s set to th e ON stat e when t he lef t li nk is i n the O N stat e, and
remains set until reset by a Reset Coil.

Reset (Unlatch) Coil

The a sso ci at ed boo lea n va ria bl e is r eset to the O FF st at e when th e lef t li nk is i n th e ON st ate, an d
remains reset until set again by a SET coil.

Retentive (Memory) Coil

The associat ed Bool ean variable will be retentive to the memory .

Note: that the action of this coil is identical to Coil, except that the associated Boolean variable
is automatically declared t o be in retentiv e memory wit hout the explicit use of t he VAR RETAIN
declaration defined in the initialization of variables in IEC-61131-3 standard.

Set Retentive (Memory) Coil

The associated boolean variable is set to the ON state when the left link is in the ON state, and
remains set until reset by a Reset Coil. The associated boolean variable will be retentive to the
memory.

Note: that the action of this coil is identical to Set (Latch) Coil, except that the associated
boolean variable is automatically declar ed to be in retentive memory without the explicit use of the
VAR RETAIN declaration defined in the initialization of variables in IEC-61131-3 standard.

Reset Retentive (Memory) Coil

The a sso ci at ed boo lea n va ria bl e is r eset to the O FF st at e when th e lef t li nk is i n th e ON st ate, an d
remains reset until set by a SET coil. The associated boolean variable will be retentive to the
memory.

Note: that the action of this coil is identical to Reset (Unlatch) Coil, except that the associated
boolean variable is automatically declar ed to be in retentive memory without the explicit use of the
VAR RETAIN declaration defined in the initialization of variables in IEC-61131-3 standard.

Positive Transition-Sensing Coil

The s ta te o f t he as so cia t ed bo olea n v ari abl e i s O N fr om one ev al uat io n of th is el em ent to the n ext
when a transition of the left link from OFF to ON is sensed. The state of the left link is always copied
to the r ight link.

The association of relays and coils create boolean functions. Below we present a brief summary of
these functions and Boolean Algebra.

The A relay is normally closed. The power fl ow passes through A powering A until the value of A
changes from 0 to 1. In this way the coil S has the contrary behavior compared to the the coil of t he

Introduction

FUNCTION BLOCKS

This is a complete and updated reference of the Function Blocks (FB) supported by the DF65 CPU.
Here we present block diagrams showing inputs, outputs, configuration parameters and internal
variables. It also includes detailed explanations of each block, how they work, how to configur e each
one of them and a few examples are presented in order to help with the user’s understanding and
utilization.

Many times, an input or output will be classified as ANY, ANY_NUM, ANY_BIT, ANY_REAL or
ANY_INT. If input is ANY_NUM it means it might be connected to either a REAL or INT output. For
a better explanation, see the t able below:

Reference Dat a Type Number of bits Version

BOOLEAN Boolean 1 1.xx or superior

INT Integer 16 2.xx or superior

REAL Float 32 2.xx or superior

WORD String 16 2.xx or superior

If the user tries to set two outputs of a function block having variables of different data types, for
example, adding an integer to a float, the LOGIC VIEW will not allow this setting. As the first block
variable is selected, it is expected that all other inputs have the same data type of this variable.

During this configuration of inputs and outputs LOGIC VIEW asks the user to inform variable data
types that should be set when the manual describes it as ANY_XX.

Each function block has a table where all inputs, outputs, parameters and variables of each block
are shown.

I - Inputs: It is a variable from another FB or from an I/O card
P - Parameter: User’s configurations.
O - Outputs: Variable s re sulting fro m processing inside each block.
V - Variables: Auxiliary variables of block algorithms.

Information about the use of point "." and comma ", " in the input of parameters of function
blocks:

The format for the numeric data input (use of "." and ",") it should be in agreement with the defined
patterns in the regional configurations of the computer.

EN Input and ENO Output

Every function has an EN input and an ENO output.
EN input is set to enable the function block that should be processed. If EN is false, all outputs
change to zero and the FB is not executed.
ENO changes to true logic to indicate the function was successfully executed without troubles.

Time and Pulse Related Functions

Pulse Accumulator (ACC)

Description

This Pulse Accumulator Block works with the DF41/DF42/DF67 Modules and the main objective of
the accumulating input pulses is coming from an external source. Typically one of the inputs from
the DF 4 1 mo dule is l in k ed to the IN input in the ACC block.

During the control cycle the DF41/DF42/DF67 accumulate pulses in a local register in the circuit. At
the end of every control cycle the DF65 CPU reads the accumulated amount and automatically
clears the internal register for the next cycle (preventing an overflow). When the control logic
executes, the ACC block gets the integer number of pulses in the IN input and adds it to an int ernal
accumulator TOT_L and TOT_H and, as can be seen, this accumulator is shared as outputs of the
ACC block.

Two actions take place when the CLRA input is high in the ACC block:
The TOT_L and TOT_H accumulated values are moved to MEM_L and MEM_H register.
The T OT_L and TOT_H contents are t hen cleared.

The Q output

This function block can also give the information of “pulse speed” (flow) in a time interval (MP) that
can be configured by the user. The Q output will keep showing an updated value of accumulated
pulses on each MP time interval.

The parameters TR_ON and TR_OFF are the hysteresis limits for the Q threshold. The THR output
will go to high when Q is higher or equal to TR_ON and will go back to low when it is lower or equal
to TR_OFF.

Accu mulator Mod e

The ACC fu nction block can c ount pulses i n the TOT_L and TOT_H register s in tw o diff erent w ays:
Maximum counting in TOT_L is 32767 and TOT_H represents how many times TOT_L

overflowed.This means that the total accumulated pulse is calculated by the following formula:
(TOT_H * 32768) + TOT_L

Maximum counting in TOT_L is 9999 and TOT_H represents how many times TOT_L
overflowed.This means that the total accumulated pulse is calculated by the following formula:
(TOT_H * 10000) + TOT_L

The accumulation mode is set during the ACC block configuration. The mode set for TOT_L and
TOT_H will be extended to MEM_L and MEM_H.

Pulse Accumulator (ACC_N)

Description

This block accumulates pulses from IN1 and IN2 inputs and displays the totalized value in the TOT1
to TOT4 outputs. CLEAR input equal to 1 clears these counters and the totalized value is moved to
the registers MEM1 and MEM2 and the totalization continues.

Factor of Multiplication of Scale

All inputs have an associated parameter to convert the inputs in Engineering Units. If the Factor is
equal to 1 the output is given in the 0 to 10000 range.

Hysteresis and Limits

Each input has two param eters to define the hysteresis of pulse totalization. Parameters TR_ON1 to
TR_ON4 and TR_OFF1 to TR_OFF4 set this hysteresis. Outputs THR1 to THR4 go to a true logic
state (1) when the flow is bigger than the values of TR_ON1 to TR_ON4 and go to the false logic
state (0) when the flow is smaller or equal than values set on TR_OFF1 to TR_OFF4. Flow is
defined as the pulse frequency in a time interval MP (user set).

Clear Input

Every time there’s a transition in the Clear input from zero to one, outputs TOT are reset and their
respective v alues are passed to the outputs MEM.

Pulse Counter Down (CTD)

Description

CTD function counts 0 (false) to 1 (true) logic state transitions, for example, an ON-OFF button.
While the button is not pressed, the ON operation is not done. When the button is pressed, the state
changes to ON. So there was an OFF/ ON transition.

Internal Counte r CTA

Every time an ascending transition occurs in the block input, the pulse accumulator (CTA) is
decreased by one unit. When the internal counter reaches zero, OUT changes to its true state. The
internal counter CTA may be accessed through an output of this function block.

RST (Reset)

If RST is equal to true, the int ernal clock will reset.

Setting the number of pulses to be counted

Internal parameter PST adjusts the number of pulses this block will count until OUT changes to the
tr ue logic s tate. On LOGIC VIEW , the user must in form the valu e of t he PST parameter. This value
may also be set through the block input PSV. In this case the user shoul d connect the PSV input to
another FB output or to an I/O module.

Pulse Counter Up (CTU)

Description

The CTU function counts transitions from 0 (false) to 1 (true).

Internal Counte r CTA

Every time an ascending transition occurs in the block input, the pulse accumulator (CTA) is
increased by one unit . When the internal counter reaches zero, OUT changes to the true state. The
internal counter CTA may be accessed through an output of this function block.

RST (Reset)

If the RST input is TRUE the counter will be cleared.

Setting the Number of Pulses to be Counted

Internal parameter PST adjusts the number of pulses this block will count until OUT changes to the
true logic state. On LOGICVIEW the user must set the value of the PST parameter. This value may
also be set through block input PSV. In this case the user should connect the PSV input to another
FB output or to an I/O module.

Real Time Alarm (RTA)

Description

This alarm is based on the DF65 CPU real time clock. When the alarm occurs the ALM output goes
to true and remains in this condition. The alarm is turned ON according to the date and hour set
inside the RTA block. The user should select the time to start the alarm and also the date. The user
may select the day of the week, the day of the month, month and year.

RST (Reset)

If a RST (RESET) is applied, the ALM output will return false but not before it remains true for at
least one second.

Time Parameter

The user must set the hour desired for the alarm to be active. This hour must be set in the format
HR:MIN:SEC, where the parameters HR, MIN and SEC are respecti vely r elated with hours, minutes
and seconds.

Day Parameter

The user may select this parameter, choosing a specific date. The Day parameter supports two
options: Day Of The Week and Day Of The Month.
If the user sets the Day Of The Week parameter, it will have to set by the named day: Sunday,
Monday, Tuesday, Wednesday, Thursday, Friday or Saturday.
If the user sets the parameter, Day Of The Month, it will have to set in the 2 digits format.

Month Parameter

The user will have to set th e month of th e year for the al arm to be activ e i n a 2-digit format

Byte to Bits Conversion (BTB)

Description

This FB converts 1 byte in 8 parall el outputs, each one of them representing one bit.

Conversion

One byte is the input of this block and the outputs (OUT_1 to OUT_8) compose the input byte in the
parallel format. The least significant bit is O UT_1 and the most significant bit is O UT_8. The input
byte may be from an I/O card, a virtual byte or another FB. Outputs can be connected to the BWL

BCD to Integer Conversion (BTI)

Description

This FB converts an input BCD value to an integer and puts the result in the OUT output.

Conversion

A 2-digit number on BCD has the following format:
BIT7-BIT6-BIT5-BIT4 _____BIT3-BIT2-BIT 1-B IT0
Each set of 4 bits composes a digit. For example: the number 10. If expressed in the BCD code it i s

written as 10. The first digit can be written in the binary form as 0001, and the second as 0000. So,
10BCD= 0001 000Binary. It is common to confuse the BCD code with the binary representation.
However, each group of 4 bits only represents one digit varying from 0 to 9. There can’t be a
representation on BCD like 12 9BCD, even though 12 can be expressed by 4 bits. The BCD code is
typically used in 7 segment displays. Each segment represents a BCD digit. The above
representation may be extended to N digits, always noting that each digit varies only from 0 to 9.

DF65 – LogicView Configuration Manual

First In First Out (FIFO)

Description

This block allows storing data with DF65. Every tim e this block is used, a non-volatile RAM area is
reserved to the database first in first out (FIFO).

FIFO size

The user may create this area directly in the SIZE parameter. The biggest size allowed will depend
on the free RAM memory available in the CPU module when the setting is being done. Data in the
FIFO and their correspondent sampling times may be accessed directly through communication with
the CPU module via Modbus/RTU or Modbus/TCP.

Control Word (CTW) - FIFO MOD E
Standard Mode:

Data is stored in the FIFO until it is full. After that, any other data can’t be stored until one or more
variables are removed.

Moving Window Mode:

Data flow is always in the IN direction of the block. In this case if the FIFO is full, an automatic
unload of the old variables is executed before the new variable can be stor ed. So, the FIFO always
keeps the most updated samples.

Circular Queue Mode:

Data flow is always in the IN direction of the block. If the FIFO is full, the new data will be stored in
the oldest data´s position. There is no change in the position of the other data.

Control Word (CTW)- FIFO Memory

Dat a logging works in 3 different w ays:

- Save Only Last Time
Saves variable and only time of the last sample.

- Do Not Save Time
Saves only the variable.

- Save Value and Time
Saves variable and sampling time for all samples.

LOAD, UNLOAD, CLEAR Inputs

Every time LOAD state changes to true, FIFO starts to store data in the IN input. At each CPU cycle
of scan time, the FIFO block reads the input variable and increments the internal pointer to the next
memory position. If UNLOAD changes to true, FIFO is unloaded. Clear input erases all memory
area reserved for the FIFO block.

Trigger

If the trigger parameter is set to an N value, output will change to true when the FIFO stores the
sample number N. Suppose Trigger is set to 9 and the FIFO size is 10 registers. When FIFO stores
the ninth value the trigger output goes to true.

EMPTY and FULL outputs

EMPTY output indicates when FIFO is completely empty if its state is equal to true.
FULL output indicates when FIFO is completely full if its state is equal to true.

Data Type

The user must select two types of data to be stored: integer or real.
1 integer DATA has 2 bytes (1 Modbus Register)
1 real DATA has 4 bytes (2 Modbus Registers)
If the user chooses the data type as integer, each register will occupy one Modbus register. There
must be a distinction between the number of registers set for FIFO and the actual number of
Modbus registers. If the chosen data type is REAL, two Modbus registers are allocated.

Sampling Time Storing Mode

FIFO always allocates Modbus addresses to store time.
Save Only Last Time: 6 bytes are allocated to register time for the last sample
Do Not Save Time: FIFO reserves this Modbus area to internal time parameters, not storing
sampling time.
Save Value and Time: To each value stored it is rese rve d one register to this data plus 3 registers (6
bytes) to store each sampling time.

2.19

Function Blocks

Allocated Modbus Addresses

FIFO is allocated by the LOGIC VIEW in a Modbus area 4xxxx (register). PTR is a pointer to the
beginning of the Modbus address of the FIFO (relative Modbus Addresses). For example, if FIFO
has 16 registers (words), Modbus registers 42501 to 42516 are addressed as 0 to 15.

Bit Wise Logic (BWL)

Description

This function allows implementation of the logic functions using a function block. Six different
function blocks can be set: AND, NAND, OR, NOR, XOR e NXOR. The user chooses the type of
logic operation during the BW L block setting and this block will perform this logic function. It has
extensions for more than 2 configurable inputs (max of 14 i nputs). If the inputs are bytes, it will
perform the logic operations bit-to-bit. If the inputs are bits, logic operations are done for each
bit/input.

Control Word - AND Function

The Logic Function of the IN1 and IN2 inputs has an output given by the following Boolean
expression:
OUT=IN1.IN2 . Thi s will result in a state table as shown below:

IN1 IN2 OUT

0 0 0
0 1 0
1 0 0
1 1 1

If the inputs are bytes, the AND function is done bit-to-bit, i.e.:
IN1= (BIT17)(BIT16)(BIT15)(BIT14)(BI T13) (BIT12) (BIT11) (BI T10)

IN2= (BIT27)(BIT26)(BIT25)(BIT24)(BI T23) (BIT22) (BIT21) (BI T20)
OUT= (BIT17ANDBIT27)…………………………(BIT11ANDBIT21)

Ex: IN1= 00001111
IN2= 11110000
OUT= 00000000

Control Word - Function NAND

This function associates the AND and NOT functions. So, the logic output is the AND logic function
inverted.

Control Word - Function OR

Logic function for the two inputs IN1 and IN2 have an output given by the expression :
OUT=IN1+IN2.
Transposed to stat e as in table below:

IN1 IN2 OUT

0 0 0
0 1 1
1 0 1
1 1 1

If the inputs are bytes, the OR function is done bit-to-bit, i.e.:
IN1= (BIT17)(BIT16)(BIT15)(BIT14)(BI T13) (BIT12) (BIT11) (BI T10)

IN2= (BIT27)(BIT26)(BIT25)(BIT24)(BI T23) (BIT22) (BIT21) (BI T20)
OUT= (BIT17ORBIT27)…………………………(BIT11ORBIT21)

Ex: IN1= 00001111
IN2= 11110000
OUT= 11111111

Control Word - Function NOR

This function associates the OR and NOT functions. So, the logic output is the OR logic function
inverted.

Control Word - Function XOR

Logic function for the two inputs IN1 and IN2 has an output given by the expression:

IN2 IN1IN2 IN1 +

OUT=

. Tr anspo sed t o state a s in the tabl e below:

2.32

DF65 – LogicView Configuration Manual

If the inputs are bytes, the XOR function is done bit-to-bit, i.e.:
IN1= (BIT17)(BIT16)(BIT15)(BIT14)(BI T13) (BIT12) (BIT11) (BI T10)
IN2= (BIT27)(BIT26)(BIT25)(BIT24)(BI T23) (BIT22) (BIT21) (BI T20)
OUT= (BIT17XORBIT27)…………………………(BIT11XORBIT21)

Example: IN1= 01011100

IN2= 11110000
OUT= 10101100

Control Word - Function NXOR

This function associates the AND and XOR functions. So, the logic output is the XOR logic function
inverted.

The BWL block allows expansion to up to 14 inputs. In the table below we present logic functions for
more than 2 inputs and their respective outputs.

Addition (ADD)

Description

This function adds all of the IN inputs and places the result in the OUT output.

Operation

If the result goes out of the limits of the data type that can be represented, OUT will be the greatest
(or shortest) possible value represented according to its type. This would be indicated as ENO=
false. The number of inputs (n) used in this operation is previously set during configuration. If the

Division (DIV)

Description

This function divides IN1 by IN2.

Operation

If the result goes out of the limits of the data type that can be represented, output will be the greatest
(or shortest) possible value that can be represented according to its type. All exceptions are
indicated by ENO equal to false.
If the user tries to set more than two inputs with variables of different data types, for example,
adding a real to an integer, LOGIC VIEW will not allow this operati on. As the first input is selected it
is expected that all other inputs will be of the same data type as the first data type. A division by
zero will produce different results according to the data type. If the variables are integer the output
will be –1. If the variables are real the result will be zero.

Comparison Functions

Equality (EQ)

Description

This function will indicate true in the OUT output if the inputs do not have a deviation greater than
the DBN value (Death Zone) of the input IN1. This block is indicated when the user desires to
compare variables in terms of equality. The DBN parameter supplies a tool to determine how close
each one of these measurements is to be considered equal.

DBN Parameter and Operation

In case only two inputs are used (IN1 and IN2) this function block performs as an equal-with-death­zone comparison, so OUT will be true only if ABS(IN1-IN2) <= DBN

For example: We have 3 inputs and DBN is equal to 10. And IN1= 12, IN2=21 e IN3= 5.
So,
ABS(IN1-IN2)= 9 < 10

ABS(IN1-IN3)= 7 < 10
Thus, as DBN = 10, OUT is equal to true.

EQ EQUALITY

IF EN=1 THEN
ENO := 1

Xlim Cross Limit and Rate-Of-Change (XLIM)

Description

This function limits a signal between static and dynamic values and also controls the rate of change.
OUT% is the filtered result of the A% input.

Static and Dynamic Limitation
Static

To limit statically, the input B is disconnected. Signal A is limited between BL and BH (user’s
settings).

Dynamic

If input B is connected it is possible to dynamically limit the input A through the B input. To achieve
more flexibility, these limits are changeable with individual gain and bias.

Control Word (CTW)- Rate of Change

Limit of rate of change may be applied in three ways, increasing, decreasing or in a specific
direction. There are 4 types of rate of change available: Check Both; Check Only Upper; Only
Actuation Rate or None.

BL and BH Parameters

If A≤BL output OUT is equal to BL.
If BL<A<BH output OUT is equal to A.
IF A≥BH output OUT is equal to BH.

Parameters GH e GL

If A≤ B.GL+BL output OUT is equal to B.GL+BL
If B.GL+BL<A<B.GH+BH output OUT is equal to a A
If A≥ B.GH+BH output OUT is equal to B.GH+BH

parameter can be adjusted to generate a hysteresis, avoiding output oscillation while the variable is
close to the limit value.

RAT Parameter and R-O-C Output

ROC output goes to true when the signal rate of change reaches the value set in t he parameter
RAT. When the input A changes faster than RAT, the variation in the output is kept inside a value
fixed by RAT until the input signal decreases to a value inferior to RAT. The ROC alarm in t his
interval is on HIGH.

Function Blocks

Totalization (TOT)

Description

This block gives the totalization of the input. This totalization is the integral of the input times a scale
factor FCF that allows the user to configure totalizati on in 3 different modes of operation. If your
application requires the computing of instantaneous totalized volume, use the TOT function block to
accomplish this task. The time basis of this calcula t ion is sec onds.

Flow is generally given in Engineering Units (EU) by units of time. For exam ple:

3

/ s flow as input of the TOT function block will have as output volume in m3.

A 1 m

TOT Output and TU Parameter

The time interval while the output is totalized is according to the value set for TU. The integration
(totalization) is kept in an internal register that goes up to 8000000 units. Output TOT is the
total ization va l u e.

dl Output

Maximum value of totalization is 8000000 and the minimum is – 8000000. Every time the function
block output reaches these values the dl output changes from false to true during an interval of time.
That particular Function Block has an internal counter. The user can reset this counting through a
command that is represented by a pulse or a button. This dl output is a second counter that counts
how many times this "CLEAR" operation was made.

FCF Parameter

The FCF param eter allows the TOT function block to operate in 4 different modes:

In is real and represents flow in Engineering Units (EU):

FCF must be equal to 1 so that the totali zation is done without any EU scale factor. (or adjust the
factor y ou wish to use) For exampl e:

So , t= 1/60 hours or 1 minute.

- IN is REAL and represents flow in percentage values.

In this case the input will be seen as a percentage represented by a REAL number in the range 0 to
100 %. FCF must be equal to the maximum value in engineering units (flow at 100%) so the
totalization is given in EUs. The TU parameter setting is similar to the previous item. The totalization
wil l be displayed in t he EU config ured.

IN is INT EGER

In this case the input will be interpreted as an integer number i n the range of 0 to 10000 (0% and
100%). FCF must be equal t o the maximum flow in EUs divided by 10000. Suppose a maximum
flow of 1 m
divided by 10000, or 0.0001. TU in this case is 1 because the unit of totalization is m
input is equal to 5000 or 50 % of the scale. Thus:

DF65 – LogicView Configuration Manual

So, in one minute (or 60 seconds) the totalized value is 30 m

- When FC is smaller than zero:

When the block is totalizing a negative flow, the totalization is decreased while when the flow is
positive the totalization is incremented. When FCF is greater than zero, positive, the TOT function
block only accepts positive flows.

Automatic Up and Down Ramp (Aramp)

Description

This function incremen ts or decrement s the OUT output i n a linear w ay bas ed on a pre- es tablished
time interval. This function block may be used to create a database to an automatic set point
generator when used together with the linearization block or a simple ramp.
In a set point application this function block is prepared to generate a 0% to 100 % output in a time
interval tracking the set point curve. The ARAMP output will be connected to the input of the LIN
function (linearization) set with a profile curve of the set point.

Control Word- Time Selection

The time basis of this block can be selected in minutes, seconds or hours according to the
requirements of the application. This selection affects directly the chosen value for the FTIME
parameter.

FTIME, INC/DECR Parameter

FTIME is the time output it takes to change from 0% to 100 %. Direction of the change is given by
the output INC/DECR. If this input is true, the output OUT will be gradually decreased with speed
defined by the FTIME parameter, otherwise, the output will be incremented with the speed defined
in the FTIME parameter.

Pause Command (PAUSE)

PAUSE freezes the output OUT so that the output can be incremented or decrement right after
pause is true through the UP and DOWN inputs.

2.54

DF65 – LogicView Configuration Manual

UP and DOWN Commands, ASPD Parameter

The UP and DOWN inputs will advance or revert the OUT output to a desired value using the
manual speed adjusted by the ASPD parameter. This parameter configures the speed of manual
actuation.

LOW_L and HIGH_L Parameters

The parameter LOW_L configures the bottom limit of the ramp generated by the ARAMP function
block while the HIGH_L parameter configures the upper limit of the output ramp. It starts from the
value in the IN input and goes to the maximum value, set in the HIGH_L parameter. If the value is
smaller than LOW_L the initial value of the ramp will be equal to LOW_L.

HIGH and LOW Alarms

When the output ramp reaches the bottom limit (LOW_L) or upper limit (HIGH_L), the alarms LOW
and HIGH will be turned on. LOW goes to high level if the bottom limit is reached. Similarly, if the
upper limit is reached the output HIGH goes to true.

ACCEL Parameter

It is the manual acceleration of actuation. When the block output is a parabola, the ACCEL
parameter allows bett er adjusting of the output, allowing more definition of the rate of change of the
output.

Function Blocks

Linearization (LIN)

Description

This block simulates a function using a table of points. Intermediate values are computed using the
linear interpolation method. They can be arranged to implement curves of more than 10 points. The
user should set a table of points, X and Y pair of points, that represent the function. A value in the X
input corresponds to an output value Y, i.e., this block creates a function f(x). To each X coordinate
there is a corresponding y. The user must enter 10 pair s of points:

(x1,y1), (x2,y2), (x3,y3), (x4,y4), (x5,y5), (x6,y6),(x7,y7),(x8,y8),(x9,y9), (x10,y10)

IN Input

This function block may work in two modes according to the input settings:
Input IN% is an integer:
In this case the function block input will be interpreted as a number in the range 0 to 10000.
Input IN% is a real:
In this case the function block input will be interpreted as a real percentage.

Bypass

If the Bypass input is on HIGH, the LIN block passes the input of the block without processing it.

Control Word (CTW)- Serial Behavior

When an application requires more than 10 points, LIN function block may be put in a series. The
DONE signal must be connected to the bypass input of the next block. The first block must be set as
FIR ST and the interm ediate blocks as INTERMEDIA TE and th e last block as LAST.

An application with 30 points will have the following configuration:

Equation 1 – Relative Humidity

The Relative Humidity output is relative humidity calculated with reference to two inputs. These
consist of temperature inputs. One of them will read from a dry bulb and other read will from a humid
bulb.

Humidity

Humidity is equal to the result of the function of moisture calculation, in the range of 0.000000 to
1000000, representing values from 0 to 100 %.

Scale Conversion to the outputs

OUT = A * Humidity + B
A and B param eters are set by the user. A is the scale GAIN of the output value OUT and B is the
BIAS of the scale of output value OUT. Example: to obtain a 0 to 100 % output, A must be set to
equal 100 and B to equal 0.

LOW and HIGH Parameters

LOW is the bottom LIMIT of the output OUT. If the output OUT is smaller than the bottom limit, it is
displa yed in the digital output LOW, i .e., LO W= 1.

HIGH is the upper limit of the output OUT. If the output OUT is smaller than the bottom limit, it is
displayed in the digital output HIGH, i.e., HIGH= 1.

2.57

Relative Humidity Equation Parameters

K1: It is a constant adjusted according to where the application is located. This value m ust be equal
to the local atmospheric pressure and it is set in the block parameters configuration windows of the
LOGICVIEW.
K2: It is the scale GAIN of input values on the inputs IN1 and IN2.
K3: Scale BIAS of the values in the inputs IN1 and IN2.

Inputs are calculated using the following equations:
Tbdry = IN1 * K2 + K3

Tbhumid = IN2* K2 + K3
To obtain a 0 to 100 °C input, where the values of IN1 and IN2 are from 0 to 10000 K2 must be

equal to 0.01 and K3 equal to 0.
K4: It shows the value of Tbdry = IN1 * K2 + K3 in Engineering Units (only for the supervision

system using Modbus communication in the Modbus Address specified by the K4 parameter).
K5: It shows the value of TbHumid= IN2*K2 + K3 in EU Units (only for the supervision system using
Modbus communication in the Modbus Address specified by the K5 parameter).

Control Word (CTW)- Select Products

The type of product should be selected in this field. Available products are crude oil, generali zed
products, MTBE and lubricating oil. Once the inputs and product are selected, we have the table
that will be used in the calculations.

Control Word (CTW)- Select Output

The user should set the type of the output. There are 2 options:

Input Scale Conversion Factors Conversion

The Input scale has two factors (parameters the user must set) to convert these parameters to
engineering units (EU). IN1 input must be adjusted through the parameters K1 (GAIN) and K2
(BIAS). Similarly IN2 input must be set through parameters K3 (GAIN) and K4 (BIAS). After
conversion they will be in the following format:

Equation 3 - Signal Processing

Description

Option Signal Processing uses an equation that filters the input signal. The filter used is a first order
exponential filter. Input IN1 receives the signal.

Characteristic Filter Time (K1)

This parameter is the characteristic time filter in seconds. Consider a step input. When the output
signal reaches 63 % of the step value, the time measured until this moment is defined as
characteristic time.

PID Controller (PID)

Description

The acclaimed PID algorithm for continuous process control, associated with the flexibility of the
configuration of the operation settings through parameterization, allow use of this block to a variety
of applications and control strategies.

This block supplies several options of settings of the algorithm having as a basis the terms
Proportional (P), Integral (I) and Derivative (D) that may be applied in error or just to the process
variable (PV).

The u ser ma y set li mits of anti-res et wi ndup (only applied to the int egral t er m).
Plus, the user might choose the type of PID algorithm: ISA or parallel, direct action or reverse,

manual to automatic transference bum pless or hard.

Control Word (CTW) - Type of PID
PI.D: P and I actions actuate over the error and the D action over the process variable. In this way

the output signal tracks set point changes according to proportional an integral action, but there is
no undesired variation due to the derivative action. It is the most recommended type for most
applications with set point adjustable by the user.

PID: P, I and D actuate over the error so that the output signal is changed when there are changes
in the processes variable or set poi nt. It is recomm ended for relation control or to cascade slave
control.

I.PD: In this type only integral action actuates over the error. Set point changes produce soft output
signal variations. It is recommended for a process that cannot have sudden changes in the variable
due to the set point change. It is the case of heating process with high GAIN.

Control Word (CTW) - Type of transference from Manual to Automatic
Bumpless: During switching from manual to automatic, the PID block will start calculations from the

last manual value, i.e., there is not a jump in the block output.

the last manual value plus the proportional term.

Anti Saturation by the integral term (AWL and AWU)

Usually the control algorithm automatically stops the contribution of the integral mode when the
output signal reaches the 0 or 100 % limits. Contributions of proportional and derivative are not
affected.
A unique characteristic of the algorithm is the possibility to set these limits. For example in
narrowing those limits through the AWL and AWU parameters, we can get faster answers while
avoiding overshoot in the heating process.

PID Constants (KP, TR, TD and BIAS)
KP –Proportional Gain
TR – Integral time in minutes per repetition, so, the larger is this parameter the shorter is the integral

action. It can be interpreted as the necessary time to the output being incremented or decreased of
the erro r value (Par allel P ID), keeping it constant.
TD –Derivative Time given in minutes. The derivative time is calculated using a false derivation, i.e.,
an action similar to a lead/lag controller, in which the lag constant is Alfa*TD. In this block
implementation the Alfa factor is equal to 0.13.
BIAS –This parameter will allow the adjustment of the initial output value when the control is
transferred from manual to automatic. This cannot be done if the function block output is connected.

The user should configure minimum pulse width per 0. 1 seconds through WPL parameter and time
for t otal excursion of the control element .

Control Word (CTW)- Control Type

The u ser mu st cho ose the cont rol type, i.e., ON_O FF or ON_NONE _OFF

ON_OFF Control

Suppose the OPEN input starts a motor that opens a valve while CLOSE output starts a motor that
closes this valve. The STP block allows these control pulses to be generated using the VOT value.
In this control mode, the block compares DMV with internal values. If DMV is greater than 80 % the
output is TRUE/ON. If it’s sm aller than 70 % the output goes to OFF/FALSE. Values between 70 %
and 80 % make the output assum e the last state.

ON_NONE_OFF Control

A PID having only proportional action with gain KP=1 and VOT equal to 1 minute. Suppose that in
the instant t= 0 a step with error 25% is applied. Thus, the valve opening is 25 % of 1 minute, or

0.25*TR= 15 seconds. Figure below shows this example:

Integral action of a PID is equal to a series of pulses with size WPL and frequency determined by
the integral time of the PID block (TR) and by the control deviation. Pulse frequency is given by the
TR value. WPL is fixed and determined during the block setting. Suppose TR= 1 minute and WPL=
3 seconds and a step with error 25 % is applied in the input. A standard controller would increase or
decrease output of 25 % on 1 minute (TR). To make the valve have an opening tim e (VOT) equal to
1 minute we need 15 seconds (25 % of 60 seconds), because WPL=3 seconds. So, 5 pulses with
width equal to 3 seconds are required. Output remains in this mode of functioning while the PID
output keeps the same rate of change.

THE LOGICVIEW

Introduction

Installation

This chapter presents the essentials for the use of the LOGICVIEW programming software for the
advanced Smar DF65 Universal Hybrid Controller. It will show how to create, download and
troubleshoot a DF65 configuration.

The user should read about the DF65 in chapter 1 “Ladder Logic". In chapter 2 "Function Blocks” to
get familiar with the ladder elements and function blocks. Next the user will be able to design a
control strategy for a specific application.

The LOGICVIEW application software is based on 32 bits Microsoft Windows and is therefore
operated in the same basic way as other Windows applications, i.e. through menus, browsing, cut
and paste, buttons, drop down lists, etc. It is assumed that the user is already familiar with Windows
interface.

This manual will also show how to generate and register the DF65 Tag List in the computer running
the DF65 OPC Server.

The DF65 OPC Server operation and setup will also be reviewed here.

Operating System

The LOGICVIEW runs on any 32bits Windows. Therefore, it is ready for Windows 95/98, Windows
NT (with service pack 3, minimum), Windows 2000, Windows Millennium (Me) and Windows XP.
However the DF65 OPC Server counts on the multi-tread feature of Windows NT (with service pack
3, minimum) and Windows 2000 therefore will automatically exclude other version of Windows.

Before Installation Begins

Verify minimum resources as listed below. It is recommended (and sometimes mandatory), that the
user stop any Anti-Virus and some display controller applications. It is best to close all applications
before installing the new software.

Minimum Resources for the LOGICVIEW

- A Pentium IV processor or higher (or equivalents as AMD, Athlon, Duron).

- 256 MB of RAM or higher.

- Hard disk with a minimum free space of 100MB

- Microsoft Windows 2000 (Service Pack 2) or Windows XP.

- A serial port or Ethernet Adapter Card to communicate with the DF65 controller

Minimum Resources for the DF65 Tag List and DF65 OPC Server

Same as above but the operating system has to be: Windows NT + Service Pack3 or higher or
Windows 2000.

Installing

The installation should automatically start a few seconds after the CD-ROM is inserted in a CD­ROM driver. If after inserting the CD-ROM into the driver the installation does not start automatically,
go to the directory containing the application and run the SETUP executable file. The installation
program will run and guide the user through out the installation procedure.

Using the LOGICVIEW

Launching the application

To start the DF65 programming software click the START button. Go to PROGRAMS and then find
the SMAR group while placing the mouse pointer over it the user will see one or more buttons with
Smar applications, and then click the LOGICVIEW application icon.

First a registration window will appear, click OK to proceed. Later the user might come back to this
screen by using the menu: Help/About LogicView.

Next select “New Configuration” on the Dialog Box shown below for a new configuration or “Open an
Existing Configuration” to open an old file.

Fig 3.1- Launching LOGICVIEW

One configuration has to be created for each DF65 system. A DF65 system is composed of one
CPU module, one or more I/O modules and 0 to 6 Remote I/O interfaces with respective I/O
modules. This means, a project with many DF65 CPUs will have one configuration file for each
CPU.

In case of redundant CPUs, both have to carry the same configuration.

Project Information

When launching the LOGICVIEW “First Page” also referred to as, the “Documentation Page”, it will
automatically appear. Fill the table with all of the pertinent information and the most important part
here is to select the appropriate DF65 version before starting configuration. Typically the CPU the
user has received is the latest version available, but one way to make sure is to connect the DF65
CPU to a serial port of the PC and go to the On-line mode. See Connecting to the DF65 topic for
more details.
The user can return to the documentation page and make changes at any time using the menu

Configuration/First Page or click

This information is valuable for project organization and documentation. Many of the printable
reports generated by the LOGICVIEW will contain this information.

.

Working Directory

LOGICVIEW allows the user to set the working directory. This directory will be used as the default
directory for saving configurations. Also when the user uploads a configuration from the DF65,
LOGICVIEW will automatically save the uploaded configuration in this directory.

To set the Working Directory click at ToolsPreferences and select the tab Directory. The following
Window will be displayed.

Click at the button “…” to change the directory.

Fig 3.4- Selecting Window

The button “Default” will reset this path to the default path to C:\Program
Files\Smar\LOGICVIEW_v8-54\Working\.
LogicView generates the backup of a configuration whenever the rescue of an alteration is made.
The extension of the backup files is ".Bxx ", where " xx " is the sequential numbering of the files of
generated backup, for example: the first backup possesses the extension .B01, second .B02 and
and so on. The amount of backup files is configured in the field shown by the illustration 3.3, being
limited by the physical capacity of HD. For use of a file backup, he/she is due rename the file for the
extension " .PL8 ".

Setting up the I/O Modules

In the last step the user selected the CPU version to be used. Now the user will need to completely
define the DF65 system hardware. To enter the “Module Page” the user may go to the menu

Configuration/Module Page or click .

For a new configuration this page will begin with a 4 slot Rack carrying a Power Supply on slot 0
(zero) and a CPU Module on slot 1 (one). Slots 2 and 3 are initially empty.

Adding Modules

To add Modules go to an empty cell on the “Module” column and click on it. A drop down arrow will
appear to the right of the cell. Now click on the down arrow and make a Module selection by clicking
on it.

As soon as the Module is selected it will be added to the corresponding empty slot and also (very
important), LOGICVIEW automatically creates memory allocation for the I/O points. The user no
longer needs to manage memory allocation as before on most of the old existing systems.

Special Modules

The user will notice that some Modules require extra configuration and a special dialog box will
automatically be launched as soon as the Module is selected. Some are Analog Input (DF44),
Analog Output (DF46), Temperature input (DF45), Foundation Fieldbus Scanner (FB700) and soon
will include DeviceNet and Profibus modules.

For example, the Temperature Module (DF45) will launch a configuration dialog box where the user
can set how the inputs are going to work.

Confi guration and Hardware Consistency

It is extremely important that the rack number and the position of each module in the configuration
match the actual hardware assembly. Many of the modules on a DF65 system are not intelligent and
the CPU cannot know if they are misplaced or non existent.

More elaborate modules, like the DF45, will cause warning messages from the FB700, if the actual
positioning does not match the software configuration.

It is strongly recommended that you printout the hardware configuration and use it to check the
actual installation.

It is necessary to go to menu File/Print and select options as indicated in the next figure then click
the OK button for an initial printout of your project.

Editing the I/O Modules

Modules can be Deleted, Replaced (deleted and placed) or simply moved to any other slot in the
DF65 system even to the slot of a Remote I/O.
It is necessary to highlight the Module to be edited. Click the column to the left of the row where the
Module is located.

Note: some icons on the tool bar are now enabled for use.

Special I/O Modul es

Many of the DF65 I/O modules can be specially configured to be adapted to application
requirements. These types of modules give the user an extra degree of flexibility. Typically modules
that are related to analog signals, special sensors and those that acquire/send signals using popular
protocols such as Modbus, DeviceNet, Profibus and Foundation Fieldbus have a dedicated level of
configuration.

Configuring the DF44 Module

This module provides 8 analog continuous signals of current or voltage. The inputs are isolated from
IMB. All DF44 inputs are differential and isolated (minimum 10mΩ) making the easy and more
reliable installation with regard to grounding subjects.

The inputs are independently configured for read:

- 10 V, 5 V, 0 to 5 Vdc or 1-5 V, with internal shunt resistor on posicion V.

- 20 mA, 0-20 mA, 4-20 mA, with internal shunt resistor on posicion I.

As soon as the DF44 is added to an empty slot the following dialog box appears. Each channel must
be independently configured. The CPU will receive the input signal already converted in a
percentage on the input range selected.

This number comes in the range from 0 to 10,000. This number has the meaning of percentage with
an imaginary fixed point to separate the last 2 decimal digits. For example 5000 represents 50.00 %
while 10000 represents 100.00 % of the inputs selected range. Another example is when the input
shows as 5460 it is actually indicating 54.60 % of the selected input range.

Configuring the DF45 Temperature Module

Each individual input in the DF45 has a particular configuration.
When the dialog box for the module configuration opens we can set the type of measurement, wiring
connectivity, sensor type, engineering units to work and range that will be converted in percentage.
The DF45 module provides both a value (integer) and a status (boolean). The status indicates that
there is a sensor burnout, high or low as selected in the configuration. This status may be used to
alert the operator and also be used for failure to make a decision in the interlock logic.

Two groups will be associated to this module:

- DF45G1B8Irrm.c, a group with 8 boolean points where each one represents the “burnout state” to
the individual inputs.

- DF45G2NR8Irrm.c, a group with 8 integer points representing the percentage of each individual
input signal.
