1 Basic Principles of PLC Ladder Diagram

Foreword: Background and Functions of PLC

PLC (Programmable Logic Controller) is an electronic device, previously called “sequence controller”. In 1978,

NEMA (National Electrical Manufacture Association) in the United States officially named it as “programmable logic

controller”. PLC reads the status of the external input devices, e.g. keypad, sensor, switch and pulses, and execute by

the microprocessor logic, sequential, timing, counting and arithmetic operations according the status of the input

signals as well as the pre-written program stored in the PLC. The generated output signals are sent to output devices

as the switch of a relay, electromagnetic valve, motor drive, control of a machine or operation of a procedure for the

purpose of machine automation or processing procedure. The peripheral devices (e.g. personal computer/handheld

programming panel) can easily edit or modify the program and monitor the device and conduct on-site program

maintenance and adjustment. The widely used language in designing a PLC program is the ladder diagram.

With the development of the electronic technology and wider applications of PLC in the industry, for example in

position control and the network function of PLC, the input/output signals of PLC include DI (digital input), AI (analog

input), PI (pulse input), NI (numeric input), DO (digital output), AO (analog output), and PO (pulse output). Therefore,

PLC will still stand important in the industrial automation field in the future.

1.1 The Working Principles of Ladder Diagram

The ladder diagram was a diagram language for automation developed in the WWII period, which is the oldest

and most widely adopted language in automation. In the initial stage, there were only A (normally open) contact, B

(normally closed) contact, output coil, timer and counter…the sort of basic devices on the ladder diagram (see the

power panel that is still used today). After the invention of PLC, the devices displayable on the ladder diagram are

added with differential contact, latched coil and the application commands which were not in a traditional power panel,

for example the addition, subtraction, multiplication and division operations.

The working principles of the traditional ladder diagram and PLC ladder diagram are basically the same. The

only difference is that the symbols on the traditional ladder diagram are more similar to its original form, and PLC

ladder diagram adopts the symbols that are easy to recognize and shown on computer or data sheets. In terms of the

logic of the ladder diagram, there are combination logic and sequential logic.

1. Combination Logic

Examples of traditional ladder diagram and PLC ladder diagram for combination logic:

Row 1: Using a normally open (NO) switch X0 (“A” switch or “A" contact). When X0 is not pressed, the contact

will be open loop (Off), so Y0 will be Off. When X0 is pressed, the contact will be On, so Y0 will be On.

DVP-PLC Application Manual

1 Basic Principles of PLC Ladder Diagram

Row 2: Using a normally closed (NC) switch X1 (“B” switch or “B” contact). When X1 is not pressed, the contact

will be On, so Y1 will be On. When X1 is pressed, the contact will be open loop (Off), so Y1 will be Off.

Row 3: The combination logic of more than one input devices. Output Y2 will be On when X2 is not pressed or

X3 and X4 are pressed.

2. Sequential Logic

Sequential logic is a circuit with "draw back” structure, i.e. the output result of the circuit will be drawn back as an

input criterion. Therefore, under the same input criteria, different previous status or action sequence will follow by

different output results.

Examples of traditional ladder diagram and PLC ladder diagram for sequential logic:

Traditional Ladder Diagram PLC Ladder Diagram

X5

Y3

X6

Y3

X5

Y3

X6

Y3

When the circuit is first connected to the power, though X6 is On, X5 is Off, so Y3 will be Off. After X5 is pressed,

Y3 will be On. Once Y3 is On, even X5 is released (Off), Y3 can still keep its action because of the draw back (i.e.

the self-retained circuit). The actions are illustrated in the table below.

Device status Action sequence

X5

X6 Y3

1 No action No action Off

2 Action No action On

3 No action No action On

4 No action Action Off

5 No action No action Off

From the table above, we can see that in different sequence, the same input status can result in different output

results. For example, switch X5 and X6 of action sequence 1 and 3 do not act, but Y3 is Off in sequence 1 and

On in sequence 3. Y3 output status will then be drawn back as input (the so-called “draw back”), making the

circuit being able to perform sequential control, which is the main feature of the ladder diagram circuit. Here we

only explain contact A, contact B and the output coil. Other devices are applicable to the same method. See

Chapter 3 “Basic instructions” for more details.

1.2 Differences Between Traditional Ladder Diagram and PLC Ladder Diagram

Though the principles of traditional ladder diagram and PLC ladder diagram are the same, in fact, PLC adopts

microcomputer to simulate the motions of the traditional ladder diagram, i.e. scan-check status of all the input devices

and output coil and calculate to generate the same output results as those from the traditional ladder diagram based

on the logics of the ladder diagram. Due to that there is only one microcomputer, we can only check the program of

the ladder diagram one by one and calculate the output results according to the program and the I/O status before the

cyclic process of sending the results to the output interface Æ re-reading of the input status Æ calculation Æ output.

The time spent in the cyclic process is called the “scan time” and the time can be longer with the expansion of the

program. The scan time can cause delay from the input detection to output response of the PLC. The longer the delay,

1-2

DVP-PLC Application Manual

1 Basic Principles of PLC Ladder Diagram

the bigger the error is to the control. The control may even be out of control. In this case, you have to choose a PLC

with faster scan speed. Therefore, the scan speed is an important specification requirement in a PLC. Owing to the

advancement in microcomputer and ASIC (IC for special purpose), there has been great improvement in the scan

speed of PLC nowadays. See the figure below for the scan of the PLC ladder diagram program.

Besides the difference in the scan time, PLC ladder and traditional ladder diagram also differ in “reverse current”.

For example, in the traditional ladder diagram illustrated below, when X0, X1, X4 and X6 are On and others are Off,

Y0 output on the circuit will be On as the dotted line goes. However, the PLC ladder diagram program is scanned from

up to down and left to right. Under the same input circumstances, the PLC ladder diagram editing tool WPLSoft will be

able to detect the errors occurring in the ladder diagram.

1.3 How to Edit Ladder Diagram

Ladder diagram is a diagram language frequently applied in automation. The ladder diagram is composed of the

symbols of electric control circuit. The completion of the ladder diagram by the ladder diagram editor is the completion

of the PLC program design. The control flow illustrated by diagram makes the flow more straightforward and

acceptable for the technicians of who are familiar with the electric control circuit. Many basic symbols and actions in

DVP-PLC Application Manual

1 Basic Principles of PLC Ladder Diagram

the ladder diagram come from the frequently-seen electromechanical devices, e.g. buttons, switches, relay, timer and

counter, etc. in the traditional power panel for automation control.

Internal devices in the PLC: The types and quantity of the devices in the PLC vary in different brand names.

Though the internal devices in the PLC adopts the names, e.g. transistor, coil, contact and so on, in the traditional

electric control circuit, these physical devices do not actually exist inside the PLC. There are only the corresponding

basic units (1 bit) inside the memory of the PLC. When the bit is “1”, the coil will be On, and when the bit is “0”, the coil

will be Off. The normally open contact (NO or contact A) directly reads the value of the corresponding bit. The

normally close contact (NC or contact B) reads the opposite state of the value of the corresponding bit. Many relays

will occupy many bits. 8 bits equal a “byte”. 2 bytes construct a “word” and 2 words combined is “double word”. Byte,

word or double words are used when many relays are processed (e.g. addition/subtraction, displacement) at the

same time. The other two devices, timer and counter, in the PLC have coil, timer value and counter value and they

have to process some values in byte, word or double word.

All kinds of internal devices in the value storage area in the PLC occupy their fixed amount of storage units.

When you use these devices, you are actually read the contents stored in the form of bit, byte or word.

Introductions on the basic internal devices in the PLC (See Ch 2. Functions of Devices in DVP-PLC for more details.)

Device Functions

The input relay is an internal memory (storage) unit in the PLC corresponding to a external

input point and is used for connecting to the external input switches and receiving external

input signals. The input relay will be driven by the external input signals which make it “0” or

“1". Program designing cannot modify the status of the relay, i.e. it cannot re-write the basic

unit of a relay, nor can it force On/Off of the relay by HPP/WPLSoft. SA/SX/SC/EH/EH2/SV

series MPU can simulate input relay X and force On/Off of the relay. But the status of the

Input relay

external input points will be updated and disabled, i.e. the external input signals will not be read

into their corresponding memories inside PLC, but only the input points on the MPU. The input

points on the extension modules will still operate normally. There are no limitations on the times

of using contact A and contact B of the input relay. The input relays without corresponding input

signals can only be left unused and cannot be used for other purposes.

& Device indication: X0, X1,…X7, X10, X11,… are indicated as X and numbered in octal

form. The No. of input points are marked on MPU and extension modules.

The output relay is an internal memory (storage) unit in the PLC corresponding to a external

output point and is used for connecting to the external load. The output relay will be driven by

the contact of an input relay, contacts of other internal devices and the contacts on itself. A

normally open contact of the output relay is connected to the external load. Same as the input

contacts, there are no limitations on the times of using other contacts of the output relay. The

output relay without corresponding output signals can only be left unused and can be used as

input relay if necessary.

& Device indication: Y0, Y1,…Y7, Y10, Y11,…are indicated as Y and numbered in octal

form. The No. of output points are marked on MPU and extension modules.

Internal relay

Step

1 Basic Principles of PLC Ladder Diagram

The internal relay does not have connection with the external. It is an auxiliary relay inside the

PLC with the functions same as those of the auxiliary (middle) relay in the electric control

circuit. Every internal relay corresponds to a basic internal storage unit and can be driven by

the contacts of the input relay, contacts of the output relay and the contacts of other internal

devices. There are no limitations on the times of using the contacts of the internal relay and

there will be no output from the internal relay, but from the output point.

& Device indication: M0, M1,…, M4095 are indicated as M and numbered in decimal form.

DVP series PLC offers a step-type control program input method. STL instruction controls the

transfer of step S, which makes it easy for the writing of the control program. If you do not use

any step program in the control program, step S can be used as a internal relay M as well as an

alarm point.

& Device indication: S0, S1,…S1023 are indicated as S and numbered in decimal form.

The timer is used for timing and has coil, contact and register in it. When the coil is On and the

Counter

estimated time is reached, its contact will be enabled (contact A closed, contact B open). Every

timer has its fixed timing period (unit: 1ms/10ms/100ms). Once the coil is Off, the contact iwlwl

be disabled (contact A open, contact B closed) and the present value on the timer will become

“0”.

& Device indication: T0, T1,…,T255 are indicated as T and numbered in decimal form.

Different No. refers to different timing period.

The counter is used for counting. Before using the counter, you have to give the counter a set

value (i.e. the number of pulses for counting). There are coil, contact and registers in the

counter. When the coil goes from Off to On, the counter will regard it as an input of 1 pulse and

the present value on the counter will plus “1”. We offer 16-bit and 32-bit high-speed counters

for our users.

& Device indication: C0, C1,…,C255 are indicated as C and numbered in decimal form.

Data processing and value operations always occur when the PLC conducts all kinds of

sequential control, timing and counting. The data register is used for storing the values or all

kinds of parameters. Every register is able to store a word (16-bit binary value). Double words

will occupy 2 adjacent data registers.

& Device indication: D0, D1,…,D9,999 are indicated as D and numbered in decimal form.

The file register is used for storing the data or all kinds of parameters when the data registers

required for processing the data and value operations are insufficient. Every file register is able

to store a 16-bit word. Double words will occupy 2 adjacent file registers. In SA/SX/SC series

1.4 How to Edit a PLC Ladder Diagram

The editing of the program should start from the left power line and ends at the right power line, a row after

another. The drawing of the right power line will be omitted if edited from WPLSoft. A row can have maximum 11

contacts on it. If 11 is not enough, you can continuously connect more devices and the continuous number will be

generated automatically. The same input points can be used repeatedly. See the figure below:

4. ANB instruction: A block connects to a device or another block in series

ANB instruction

5. ORB instruction: A block connects to a device or another block in parallel

ORB instruction

If the ANB and ORB operations are with several blocks, the operation should be performed from up to down or

left to right, combining into a block or network.

6. MPS, MRD, MPP instructions: Bifurcation point of multiple outputs, for generating many and diverse outputs.

MPS instruction is the start of the bifurcation point. The bifurcation point is the intersection of the horizontal line

and vertical line. We will have to determine whether to give a contact memory instruction by the contact status of the

same vertical line. Basically, every contact can be given a memory instruction, but considering the convenience of

operating the PLC and the limitation on its capacity, some parts in the ladder diagram will be omitted during the

conversion. We can determine the type of contact memory instruction by the structure of the ladder diagram. MPS is recognized as “┬” and the instruction can be given continuously for 8 times.

MRD instruction is used for reading the memory of the bifurcation point. Due to that the same vertical line is of

the same logic status, in order to continue analyzing other ladder diagrams, we have to read the status of the original contact again. MRD is recognized as “├”.

MPP instruction is used for reading the start status of the top bifurcation point and popping it out from the stack.

Since MPP is the last item on the vertical line, the vertical line ends at this point.

MPP is recognized as “└”. Using the method

MPS

given above for the analysis cannot be wrong.

However, sometimes the compiling program will ignore

MPS

the same output status, as shown in the figure.

7. STL instruction: Used for designing the syntax of the sequential function chart (SFC).

STL instruction allows the program designer a clearer and readable picture of the sequence of the program as

when they draw a sequence chart. From the figure below, we can see clearly the sequence to be planned. When the

step S moves to the next step, the original S will be “Off". Such a sequence can then be converted into a PLC ladder

diagram and called “step ladder diagram”.

See the ladder diagram below. There are 2 ways to indicate the ladder by instruction programs with the same result.

Ideal way Less ideal way

LD X0 LD X0

LD X2 LD X2

The two instruction programs will be converted into the same ladder diagram. The difference between the ideal

one and less ideal one is the operation done by the MPU. For the ideal way, the combination is done block by block

whereas the less idea way combines all the blocks combine with one another in the last step. Though the length of

the program codes of the two ways are equal, the combination done in the last step (by ANB instruction, but ANB

cannot be used continuously for more than 8 times) will have to store up the previous calculation results in advance.

In our case, there are only two blocks combined and the MPU allows such kind of combination. However, once the

number of blocks exceed the range that the MPU allows, problems will occur. Therefore, the best way is to execute

the block combination instruction after a block is made, which will also make the logic sequence planned by the

programmer more in order.

In this example, the program codes and the operation memory in the MPU increase in the less ideal way.

Therefore, it is better that you edit the program following the defined sequence.

 Incorrect Ladder Diagram

PLC processes the diagram program from up to down and left to right. Though we can use all kinds of ladder

symbols to combine into various ladder diagrams, when we draw a ladder diagram, we will have to start the diagram

from the left power line and end it at the right power line (In WPLSoft ladder diagram editing area, the right power line

is omitted), from left to right horizontally, one row after another from up to down. See bellows for the frequently seen

incorrect diagrams:

OR operation upward is not allowed.

“Reverse flow” exists in the signal circuit from the beginning of input to output.

Re verse flow

The up-right corner should output first.

Combining or editing should be done from the up-left to the bottom-right. The dotted-lined area should be moved up.

Parallel operation with empty device is not allowed.

Empty device cannot do operations with other devices.

1.7 Basic Program Designing Examples

 Start, Stop and Latched

In some application occasions, we need to use the transient close/open buttons for the start and stop of an equipment.

To maintain its continuous action, you have to design latched circuits.

Example 1: Stop first latched circuit

When the normally open contact X1 = On and the

normally closed contact X2 = Off, Y1 will be On. If you make

X2 = On at this time, Y1 will be Off. It is the reason why this is

called “stop first”.

Example 2: Start first latched circuit

When the normally open contact X1 = On and the

normally closed contact X2 = Off, Y1 will be On and latched. If

you make X2 = On at this time, Y1 will continue to be On

because of the latched contact. It is the reason why this is

called “start first”.

Example 3: Latched circuit for SET and RST instructions

See the diagram in the right hand side for the latched

circuit consist of RST and SET instructions.

In the stop first diagram, RST is placed after SET. PLC

executes the program from up to down, so the On/Off of Y1 will

be determined upon its status in the end of the program.

Therefore, when X1 and X2 are enabled at the same time, Y1

will be Off. It is the reason why this is called “stop first”.

In the start first diagram, SET is placed after RST. When

X1 and X2 are enabled at the same time, Y1 will be On. It is

the reason why this is called “start first”.

Example 4: Power shutdown latched

The auxiliary relay M512 is latched (see instruction

sheets for DVP series PLC MPU). The circuit can not only be

latched when the power is on, but also keep the continuity of

the original control when the power is shut down and switched

on again.

X1 and X3 enables and disables Y1; X2 and X4 enables and disables Y2, and all are latched. Due to that the

normally open contact of Y1 is connected to the circuit of Y2 in series, Y1 becomes an AND condition for Y2.

Therefore, only when Y1 is enabled can Y2 be enabled.

Which of the X1 and X2 is first enabled decides either the corresponding output Y1 or Y2 will be enabled first.

Either Y1 or Y2 will be enabled at a time, i.e. Y1 and Y2 will not be enabled at the same time (the interlock). Even X1

and X2 are enabled at the same time, Y1 and Y2 will not be enabled at the same time due to that the ladder diagram

program is scanned from up to down. In this ladder diagram, Y1 will be enabled first.

Example 7: Sequential control

If we serially connect the normally closed contact

Y1

of Y2 in example 5 to the circuit of Y1 as an AND

condition for Y1 (as the diagram in the left hand side),

the circuit can not only make Y1 as the condition for Y2,

Y2

but also allow the stop of Y1 after Y2 is enabled.

Therefore, we can make Y1 and Y2 execute exactly the

sequential control.

Example 8: Oscillating circuit

An oscillating circuit with cycle ΔT+ΔT

Y1

The ladder diagram above is a very simple one. When the program starts to scan the normally closed contact

Y1, Y1 will be closed because coil Y1 is Off. When the program then scan to coil Y1 and make it On, the output will be

1. When the program scans to the normally closed contact Y1 again in the next scan cycle, because coil Y1 is On, Y1

will be open and make coil Y1 Off and output 0. The repeated scans will result in coil Y1 outputs oscillating pulses by

the cycle ΔT(On)+ΔT(Off).

1 Basic Principles of PLC Ladder Diagram

The rising-edge differential instruction of X0 makes coil M0 generate a single pulse of ΔT (one scan cycle).

Coil Y1 will be On during this scan period. In the next scan period, coil M0 will be Off and the normally closed contact

M0 and Y1 will all be closed, making coil Y1 continue to be On until another rising-edge arrives in input X0, making

coil M0 On for another scan period and Y1 Off. Such kind of circuit relies on an input to make two actions execute

interchangeably. Also from the timing diagram on the last page, we can see that input X0 are square pulse signals of

the cycle T and coil Y1 output are square pulse signals of the cycle 2T.

When input X0 is On, due to that its corresponding normally closed contact is Off, time T10 will be Off and the

output coil Y1 will be On. T10 will be On and start to count until input X0 is Off. Output coil Y1 will be delayed for

100 seconds (K1,000 × 0.1 sec = 100 secs) and be Off. See the timing diagram above.

Example 12: Output delay circuit

The output delay circuit is the circuit composed of two timers. When input X0 is On and Off, output Y4 will be

The counting range of a 16-bit counter is 0 ~ 32,767. As

the circuit in the left hand side, using two counters can

increase the counting range to n1*n2. When the counting

of counter C5 reaches n1, C6 will start to count for one

time and reset for counting the pulses from X13. When

the counting of counter C6 reaches n2, the pulses from

input X13 will be n1*n2.

2.2 Values, Constants [K] / [H]

K Decimal form

Constant

H Hexadecimal form

For different control purposes, there are five types of values inside DVP-PLC for executing the operations. See

the explanations bellows for the functions and works of every type of value.

1. Binary value (BIN)

K-32,768 ~ K32,767 (16-bit operation) K-2,147,483,648 ~ K2,147,483,647 (32-bit operation)

H0 ~ HFFFF (16-bit operation) H0 ~ HFFFFFFFF (32-bit operation)

All the operations and storage of values in PLC are conducted in BIN. Belows are the terms for BIN values.

Bit: Nibble:

The basic unit for a BIN value, either 1 or 0.

Composed of 4 continuous bits (e.g. b3 ~ b0). Presented as the decimal value 0 ~ 9 of a digit

or 0 ~ F in hex.

Byte: Word:

Composed of 2 continuous nibble (i.e. 8 bits, b7 ~ b0). Presented as 00 ~ FF in hex.

Composed of 2 continuous bytes (i.e. 16 bits, b15 ~ b0). Presented as 4-digit 0000 ~ FFFF in

hex.

Double word:

Composed of 2 continuous words (i.e. 32 bits, b31 ~ b0). Presented as 8 digit 00000000 ~

FFFFFFFF.

Bit, nibble, byte, word, and double word in a binary system:

2. Octal value (OCT)

The No. of external input and output terminals in DVP-PLC is numbered in octal system.

For example:

External input: X0 ~ X7, X10 ~ X17…(device No.)

DVP-PLC Application Manual

2 Functions of Devices in DVP-PLC

External output: Y0 ~ Y7, Y10 ~ Y17…(device No.)

3. Decimal value (DEC)

Occassions of using decimal values in DVP-PLC:

 Set value in timer T and counter C, e.g. TMR C0 K50 (constant K)

 No. of device S, M, T, C, D, E, F, P, I, e.g. M10, T30. (device No.)

 Operands in application instructions, e.g. MOV K123 D0 (constant K)

4. Binary code decimal (BCD)

A decimal datum is presented by a nibble or 4 bits. Therefore, a continuous 16 bits can be presented as a 4-digit

decimal value. BCD is mainly used on reading the input value from the DIP switch or the data output to a 7-section

display.

5. Hexadecimal value (HEX)

Occassion of using hexadecimal values:

 Operands in application instructions, e.g. MOV H1A2B D0 (constant H)

Constant K:

“K” is normally placed before a decimal value in the PLC. For example, K100 refers to a decimal value, 100.

Exception:

K and bit devices X, Y, M and S can combine into data in bit, byte, word or double word, e.g. K2Y10, K4M100.

Here K1 refers to a 4-bit data and K2 ~ K4 refer to 8-bit, 12-bit and 16-bit data.

Constant H:

“H” is normally placed before a hexadecimal value in the PLC. For example, H100 refers to a hexadecimal value,

100.

2.3 Numbering and Functions of External Input/Output Contacts [X] / [Y]

No. of input/output contacts (in octal):

The No. of input and output contacts on the PLC MPU starts from X0 and Y0. The range of the No. varies upon

the number of points on the MPU. For I/O extension units, the No. of input and output contacts is calculated according

to its connection sequence with the MPU.

Note 1: The output type of 28SV11T is transistor output, among which CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4) and CH3 (Y6)

are high-speed transistor output (200KHz); others are normal transistor output (10KHz).

Note 2: The input points on I/O extension units start from X20 and output points start from Y20. The calculation on the No. of

I/O points is the same as that in SS series.

 Input Relay X0 ~ X377

The numbering of input relays (or input terminals) is in octal form. EH series MPU can have up to 256

points and the range is: X0 ~ X7, X10 ~ X17, …, X370 ~ X377.

 Output Relay Y0 ~ Y377

The numbering of output relays (or output terminals) is also in octal form. EH series MPU can have up to

256 points and the range is: Y0 ~ Y7, Y10 ~ Y17, …, Y370 ~ Y377.

 Functions of input contact X

The input contact X is connected to the input device and reads the input signals into the PLC. There is no

limitation on the times of using contact A or B of input contact X in the program. On/Off of the input contact X

only changes with On/Off of the input device. You cannot use the peripheral devices (HPP or WPLSoft) to force

On/Off of the input contact X.

The special relay M1304 in SA/SX/SC/EH series MPU allows the peripheral devices HPP or WPLSoft to

force On/Off of the input contact X, but the PLC will not be able to receive external input signals at this time.

 Functions of output contact Y

Output contact Y sends out On/Off signals to drive the load connected to output contact Y. There are two

types of output contacts, relay and transistor. Thereis no limitation on the times of using contact A or B of output

contact Y in the program, but the No. of output coil Y can only be used once in the program; otherwise

according to the scan principle of the PLC program, the output status will be determined by the circuit of the last

output Y in the program.

status will be read in in the next scan.

3. There will be approximately a 10ms delay from the

On→Off or Off→On changes to the status being

recognized by the contact in the program. The delay

time may be affected by the scan time in the

program.

 Program processing

After the PLC reads the On/Off status of every input

signal in the input signal memory, it will start to execute

every instruction in the program in order starting from

address 0. The execution result (On/Off of every output

coil) will be stored in order into the device memory.

 Regenerate output

1. When the program executes to END instruction, it

will send the On/Off status of Y in the device memory

to the output latched memory. The output latched

memory is the coil of the output relay.

2. There will be a 10ms delay from OnÆOff or OffÆOn

of the relay coil to the On/Off status of the contact.

3. There will be a 10 ~ 20us delay from OnÆOff or

OffÆOn of the transistor module to the On/Off status

of the contact.

Functions of auxiliary relays:

Both auxiliary relay M and output relay Y have output coils and contact A, B, and there is no limitation on the

times of using the contact. You can use auxiliary relay M to assemble a control loop, but it cannot directly drive the

external load. There are three types of auxiliary relays:

1. General purpose auxiliary relay: If the relay encouters power cut during the operation of the PLC, its status will

be reset to Off and stay Off when the power is on again.

2. Latched auxiliary relay: If the relay encounters power cut during the operation of the PLC, its status will be

retained and stay at the status before the power cut when the power is on again.

3. Special purpose auxiliary relay: Every relay of this kind has its specific function. Do not use undefined special

purpose auxiliary relay. See 2.10 for special puspose auxiliary relay of all series MPU and 2.11 for its functions.

Functions of step relays:

The step relay S can easily set up the procedure in the industrial automation, which is the most basic device in

the the sequential function chart (SFC) and has to be used with STL, RET instructions.

The device No. of S is S0 ~ S1023 (total 1,024 points) and both step relay S and output relay Y have output coils

and contact A, B, and there is no limitation on the times of using the contact. S cannot directly drive the external load.

When the step relay is not used in SFC, it can be used as a normal auxiliary relay. There are four types of step relays:

1. Initial step relay: S0 ~ S9, total 10 points, used for initial steps.

2. Zero return step relay: S10 ~ S19, total 10 points. S10 ~ S19 are planned for zero return when used with API 60

IST instruction in the program. If they are not used with IST, they will become normal step relays.

3. General purpose step relay: S20 ~ S511, total 492 points (for SA/SX/SC series MPU); S20 ~ S499, total 480

points (for EH/EH2/SV series MPU). Used for general purposes in SFC and their status will all be cleared when

the operation of the PLC encounters power cut.

4. Latched step relay: S512 ~ S895, total 384 points (for SA/SX/SC series MPU); S20 ~ S127, total 108 points (for

ES/EX/SS series MPU); S500 ~ S899, total 400 points (for EH/EH2/SV series MPU). Used for latched function in

SFC and their status will all be retained when the operation of the PLC encounters power cut. They will remain at

the status before the power cut when the PLC is powered again.

5. Alarm step relay: S896 ~ S1023, total 128 points (for SA/SX/SC series MPU); S900 ~ S1023, total 124 points

(for EH/EH2/SV series MPU). Used with alarm driving instruction API 46 ANS as an alarm contact for recording

the alarm messages or eliminating external malfunctions.

Functions of timers:

The units of the timer are 1ms, 10ms and 100ms and the counting method is counting up. When the present

value in the timer equals the set value, the output coil will be On. The set value should be a K value in decimal and the

data register D can also be a set value.

3. Subrountine timer:

Timer T192 ~ T199 are used in subrountines or interruption subroutines.

For SA series MPU: The timer executes once when the program reaches END instruction. When END instruction

is executed, the output coil will be On when the timing reaches its target.

For EH/EH2/SV series MPU: The timer executes once when the program reaches TMR or END instruction. When

TMR or END instruction is executed, the output coil will be On when the PV equals SV.

If the general purpose timer is used in a subroutine or interruption subroutine but the subroutine is not being

executed, the timer will not be able to time correctly.

How to designate SV: The actual set time in the timer = timing unit × set value

a) Designating constant K: SV is a constant K

b) Indirectly designating D: SV is data register D

Functions of counters:

When the pulse input signals of the counter go from Off to On and the present value in the counter equals the

set value, the output coil will be On. The set value should be a K value in decimal and the data register D can also be

a set value.

16-bit counters C0 ~ C199:

1. The setup range of 16-bit counter: K0 ~ K32,767. K0 is the same as K1. The output contact will be On

immediately when the first counting starts.

2. PV in the general purpose counter will be cleared when the power of the PLC is switched off. If the counter is a

latched type, the counter will retain the PV and contact status before the power is off and resume the counting

3. If you use MOV instruction, WPLSoft or HPP to send a value bigger than the SV to the present value register of

C0, next time when X1 goes from Off to On, the contact of counter C0 will be On and its PV will equal SV.

4. The SV in the counter can be constant K (set up directly) or the values in register D (set up indirectly, excluding

special data registers D1000~ D1999).

5. If you set up a constant K as the SV, it should be a positive value. Data register D as SV can be positive or

negative. When the PV reaches up to 32,767, the next PV will turn to -32,768.

b) X10 and X11 can be set to be rising-edge or falling-edge counting. X10 is set by D1166 and X11 by D1167. K0:

rising-edge counting; K1: falling-edge counting; K2: rising-/falling-edge counting (only available in X10).

c) Counting up or down of C243 is determined by On/Off status of M1243 anc that of C245 is determined by

On/Off of M1245. Rising-edge and falling-edge countings cannot be performed at the same time. Rising edge

or falling edge of C250 is determined by the content (K0 or K1) in D1166. C255 can only be used in 4 times

frequency counting and rising-edge and falling-edge triggers are not available for C255.

d) When you use C243 or C245, you will not be able to use C250 or C255, and vice versa.

f) Explanations on high-speed counter and high-speed comparator:

(i) When DHSCS and DHSCR instructions use new added high-speed counters, they can only use two

groups of SVs in high speed comparison instruction. Assume you have used the comparison instruction

DHSCS D0 C243 Y10, you can only set another group of instruction DHSCR D2 C243 Y10 or DHSCS D4

C245 Y10.

DVP-PLC Application Manual

2-19

2 Functions of Devices in DVP-PLC

(ii) When DHSZ instruction uses new added high-speed counters, it can only use one group of SV in the

comparator.

(iii) The number of SVs in high speed comparison instructions offered by SA/SX series MPU will not decrease

owing to the increasing of high-speed counters.

(iv) If the output device of the high-speed comparison instruction DHSCS requires high-speed output, it is

recommended you use Y10 or Y11 for the output. If you use other general devices, the output will delay

for 1 scan period for its setup or clearing. For example, if I0x0 interruption is set, C243 will correspond to

I020, C245 to I040, and C250 and C255 to I060.

(v) The high speed comparison instruction DHSCR is able to clear the counter, but only the counters used in

the same instruction, e.g. DHSCR K10 C243 C243. This function only applies to 4 special high-speed

counters C243, C245, C250 and C255.

5. Counting modes:

a) The 2-phase 2 inputs counting mode of the high speed counters in ES/EX/SS (V5.5 and above) and

SA/SX/SC series MPU is set by special D1022 with normal frequency, double frequency and 4 times

frequency modes. The contents in D1022 will be loaded in in the first scan when PLC is switched from STOP

to RUN.

speed counter with a total bandwidth of 20KHz, can be used alone with a counting frequency of up to 10KHz. C241 ~

C254 are hardware high speed counter (HHSC). There are four HHSC in EH/EH2/SV series MPU, HHSC0 ~ 3. The

pulse input frequency of HHSC0 and HHSC1 can reach 200KHz and that of HHSC2 and HHSC3 can reach 20KHz (1

phase or A-B phase). The pulse input frequency of HHSC0 ~ 3 of 40EH2 series MPU can reach 200KHz, among

which:

 C241, C246 and C251 share HHSC0

 C242, C247 and C252 share HHSC1

 C243, C248 and C253 share HHSC2

 C244, C249 and C254 share HHSC3

1. Every HHSC can only be designated to one counter by DCNT instruction.

2. There are three counting modes in every HHSC (see the table below):

a) 1-phase 1 input refers to “pulse/direction” mode.

b) 1-phase 2 inputs refers to “clockwise/counterclockwise (CW/CCW)” mode.

c) 2-phase 2 inputs refers to “A-B phase” mode.

There are five types of registers:

1. General purpose register: When PLC goes from RUN to STOP or the power of the PLC is switched off, the data

in the register will be cleared to “0”. When M1033 = On and PLC goes from RUN to STOP, the data will not be

cleared, but will still be cleared to “0” when the power is off.

2-28

DVP-PLC Application Manual

2 Functions of Devices in DVP-PLC

2. Latched register: When the power of PLC is switched off, the data in the register will not be cleared but will retain

at the value before the power is off. You can use RST or ZRST instruction to clear the data in the latched register.

3. Special purpose register: Every register of this kind has its special definition and purpose, mainly for storing the

system status, error messages and monitored status. See 2.10 and 2.11 for more details.

4. Index register E, F: The index register is a 16-bit register. There are 2 points of E, F in ES/EX/SS series MPU; 8

points (E0 ~ E3, F0 ~ F3) in SA/SX/SC series MPU; 16 points (E0 ~ E7, F0 ~ F7) in EH/EH2/SV series MPU. If the

index register is to be used as a 32-bit register, please designate E. When E is already designated in a 32-bit

instruction, using also F will not be allowed.

5. File register: There are 1,600 file registers (K0 ~ K1,599) in SA/SX/SC series MPU and 10,000 file registers (K0

~ K9,999) in EH/EH2/SV series MPU. The file register does not have an exact device No.; therefore the read/write

function of file registers has to be executed by instruction API 148 MEMR, API 149 MEMW or through peripheral

devices HPP and WPLSoft.

2.8.2 Index Register [E], [F]

Index registers E, F are 16-bit data registers and can be written and

If you need to use a 32-bit register, you have to designate E. In this

case, F will be covered by E and cannot be used anymore; otherwise,

the content in E (32-bit) will be incorrect. We suggest you use DMOVP

K0 E instruction, the content in E (including F) will be cleared to “0”

KnY, KnM, KnS, T, C, D) and bit devices (X, Y, M, S). ES/SA series MPU does not support constant (K, H) index

register, but EH/EH2/SV series MPU supports constant (K, H) index register.

ES/EX/SS series MPU has 2 points of index registers E0, F0

SA/SX/SC series MPU has 8 points of index registers E0 ~ E3, F0 ~ F3

EH/EH2/SV series MPU has 16 points of index registers E0 ~ E7, F0 ~ F7

 Some instructions do not support index registers. For how to use index register E, F to modify the operands, see

Chapter 5.4 for more details.

 When you use the instruction mode in WPLSoft to generate constant (K, H) index register function, please use

symbol “@”. For example, “MOV K10@E0 D0F0”

DVP-PLC Application Manual

2-29

2 Functions of Devices in DVP-PLC

 When you use index register E, F to modify the operands, the modification range CANNOT exceed the range of

special purpose registers D1000 ~ D1999 and special auxiliary registers M1000 ~ M1999 in case errors may occur.

2.8.3 Functions and Features of File Registers

When the power of PLC is switched on, SA/SX/SC and EH/EH2/SV series MPU will check the following devices:

1. M1101 (whether the file register is enabled)

2. D1101 (No. of file registers in SA/SX/SC series MPU: K0 ~ K1,599; No. of file registers in EH/EH2/SV series MPU:

K0 ~ K9,999)

3. D1102 (Number of file registers to be read in SA/SX/SC series MPU: K0 ~ K1,600; number of file registers to be

read in EH/EH2/SV series MPU: K0 ~ K8,000)

4. D1103 (devices for storing the data read from file registers; the No. of designated data register D starts from

K2,000 ~ K9,999; determining whether to automatically send the content in the file register to the designated data

register.)

Note:

1. When D1101 of SA/SX/SC series MPU is bigger than 1,600, D1101 of EH/EH2/SV series MPU is bigger than

8,000 and D1103 is smaller than 2,000 or bigger than 9,999, the data read from file registers will not be sent to

data register D.

2. When the program starts to send the data read from the file register to data register D and the address of the file

register or the data register D exceed their ranges, PLC will stop the reading.

3. There are 1,600 file registers in SA/SX/SC series MPU and 10,000 in EH/EH2/SV series MPU. The file register

does not have an exact device No.; therefore the read/write function of file registers has to be executed by

instruction API 148 MEMR, API 149 MEMW or through peripheral devices HPP and WPLSoft.

4. If you tend to read a file register with an address that is not within the range, the read value will be “0”.

Interruption Pointer I: Used with API 04 EI, API 05 DI, API 03 IRET. See Chapter 5.5 for more details. There are 6

types of interruption pointer. To insert an interruption, you have to combine the action with EI (enable interruption), DI

(disable interruption), IRET (interruption return) instructions.

1. External interruption:

Due to the special hardware design inside the MPU, the input signals coming in at input

terminals X0 ~ X5 when rising-edge or falling-edge triggers will not be affected by the scan cycle. The currently

executed program will be interrupted immediately and the execution will jump to the designated interruption

subroutine pointer I00□(X0), I10□(X1), I20□(X2), I30□(X3), I40□(X4), I50□(X5). Till the execution reaches

IRET instruction, the program will return to the original position and keep on its execution.

In SA/SX series MPU, X0 (pulse input point) works with X4 (external interruption point), corresponding to C235,

C251 and C253 work with I401, which will be able to interrupt and intercept the present value in the high-speed

counter. D1181 is the device to store the 32-bit value. X1 (pulse input point) works with X5 (external interruption

point), corresponding to C236 works with I501, which will be able to interrupt and intercept the present value in

the high-speed counter. D1198 and D1199 are the devices to store the 32-bit value.

In SC series MPU, X10 (pulse input point) works with X4 (external interruption point), corresponding to C243 and

C255 work with I401, which will be able to interrupt and intercept the present value in the high-speed counter.

D1180 and D1181 are the devices to store the 32-bit value. X11 works with X5, corresponding to C245 works with

I501, which will be able to interrupt and intercept the present value in the high-speed counter. D1198 and D1199

are the devices to store the 32-bit value.

2. Timed interruption:

PLC automatically interrupts the currently executed program every a fixed period of time and

jumps to the execution of a designated interruption subroutine.

3. Interruption when the counting reaches the target:

The high-speed counter comparison instruction API 53

DHSCS can designates that when the comparison reaches the target, the currently executed program will be

interrupted and jump to the designated interruption subrountine executing the interruption pointers I010, I020,

I030, I040, I050 and I060.

4. Pulse interruption:

The pulse output instruction API 57 PLSY can be set up that the interruption signal is sent out

synchronously when the first pulse is sent out by enabling flags M1342 and M1343. The corresponding

2-32

DVP-PLC Application Manual

2 Functions of Devices in DVP-PLC

interruptions are I130 and I140. You can also set up that the interruption signal is sent out after the last pulse is

sent out by enabling flags M1340 and M1341. The corresponding interruptions are I110 and I120.

5. Communication interruption:

I150: When the communication instruction RS is being used, you can send out interruption request when the

program receives a specific word by interruption I150. The specific word is set up in the low byte of D1168. This

function can be adopted when the PLC receives data of different length during the connection with the

communication device. Set up the end word in D1168 and write the interruption subroutine I150 and when the

PLC receives this end word, the program will execute I150.

I160: RS instruction sends out interruption request when receiving a specific length of data. When the data

received equals the low byte of D1169, I160 will be triggered. When D1169 = 0, I160 will not be triggered.

I170: In Slave mode, interruption I170 will be generated when the data receiving is completed. Normally when the

communication terminal of the PLC is in Slave mode, PLC will not immediately process the communication data

entered but process it after the END is executed. Therefore, when the scan time is very long and you need the

communication data to be processed immediately, you can use interruption I170 for this matter.

6. Frequency measurement card triggered interruption:

I180: When the PLC sets up the frequency measurement card in mode 1 (pulse cycle measurement) and mode 3

(pulse number counting) by M1019 and D1034, I180 will be supported as well.

Function Group Number

PLC Operation Flag

M1000 ~ M1003

M1000:

M1000 (A contact) is constantly “On” during operation and detection. When PLC is in RUN status, M1000 remains

“On”.

M1001:

M1001 (B contact) is constantly “On” during operation and detection. When PLC is in RUN status, M1001 remains

“On”.

M1002:

M1002 is “On” during the first scan when PLC starts to RUN and remains “Off” afterward. The pulse width = 1 scan

time. Use this contact for all kinds of initial settings.

M1003:

M1003 is “Off” during the first scan when PLC starts to RUN and remains “On” afterward. M1003 enables

negative-direction (“Off” immediately when RUN) pulses.

Monitor Timer

D1000

Contents:

1. Monitor timer is used for moitoring PLC scan time. When the scan time exceeds the set time in the moitor timer,

the red ERROR LED indicator remains beaconing and all outputs will be “Off”.

2. The initial set value of the time in the monitor timer is 200ms. If the program is long or the operation is too

complicated, MOV instruction can be used for changing the set value. See the example below for SV = 300ms.

Initial pulse

3. The maximum set value in the monitor timer is 32,767ms. Please be noted that if the SV is too big, the timing of

detecting operational errors will be delayed. Therefore, it is suggested that you remain the scan time of shorter

than 200ms.

4. Complicated instruction operations or too many extension modules being connected to the MPU will result in the

scan time being too long. Check D1010 ~ D1012 to see if the scan time exceeds the SV in D1000. In this case,

besides modifying the SV in D1000, you can also add WDT instruction (API 07) into the PLC program. When the

CPU execution progresses to WDT instruction, the internal monitor timer will be cleared as “0” and the scan time

will not exceed the set value in the monitor timer.

c) When on-line editing is being conducted.

3. The syntax check may start due to illegal use of instruction operands (devices) or incorrect program syntax loop.

The error can be detected by the error code in D1004 and error table. The address where the error exists will be

stored in D1137. (The address value in D1137 will be invalid if the error is a general loop error.)

4. See Chapter 2.12 for error codes for syntax check.

Data Backup Memory

M1005~M1007

DVP-PLC Application Manual

2 Functions of Devices in DVP-PLC

When the data backup memory card is installed in EH/EH2 MPU, MPU will operate according to the On/Off of switch

on the card. If the switch is “On”, the following comparisons will be conducted and the card will be copied to MPU. If

the switch is “Off”, MPU will not perform any action.

1. M1005 = On: An error occurs in the comparison between the ciphers of MPU and the data backup memory card

and MPU does not perform any action.

2. M1006 = On: The data backup memory card has not been initialized.

3. M1007 = On: Data in the program area of the data backup memory card do not exist, it means data doesn’t exist

in the program area of data backup memory card.
