Read the physical input status and store the data in internal memory.

Evaluate the user program with data stored in internal memory. Program scanning starts from up to down and left to right until reaching the end of the program.

Write the evaluated data to the physical outputs

Input signal:

PLC reads the ON/OFF status of each input and stores the status into memory before evaluating the user program.

Once the external input status is stored into internal memory, any change at the external inputs will not be updated until next scan cycle

Scan time

The duration of the full scan cycle (read, evaluate, write) is called “scan time.” With more I/O or longer program, scan time becomes longer.

PLC measures its own scan time and stores the value (0.1ms) in register

D1010, minimum scan time in register D1011, and maximum scan time in register D1012.

Scan time can also be measured by toggling an output every scan and then measuring the pulse width on the output being toggled.

Scan time can be calculated by adding the known time required for each

instruction in the user program. For scan time information of individual instruction please refer to Ch3 in this manual.

1. PLC Concepts

Scan time exception

PLC can process certain items faster than the scan time. Some of these items interrupts and halt the scan time to process the interrupt subroutine program. A direct I/O refresh instruction REF allows the PLC to access I/O immediately during user program evaluation instead of waiting until the next scan cycle.

1.2 Current Flow

Ladder logic follows a left to right principle. In the example below, the current flows through paths started from either X0 or X3.

Reverse Current

When a current flows from right to left, which makes a reverse current logic, an error will be detected when compiling the program. The example below shows the reverse current flow.

1.5.1 Creating a PLC Ladder Program

The editing of the program should start from the left side bus line to the right side bus line, and from up to down. However, the right side bus line is omitted when editing in WPLSoft. A single row can have maximum 11 contacts on it. If more than 11 contacts are connected, a continuous symbol “0” will be generated automatically and the 12th contact will be placed at the start of next row. The same input points can be used repeatedly. See the figure below:

When evaluating the user program, PLC scan starts from left to right and proceeds to next row down until the PLC reaches END instruction. Output coils and basic / application instructions belong to the output process and are placed at the right of ladder diagram. The sample program below explains the execution order of a ladder diagram. The numbers in the black circles indicate the execution order.

1.5.11 STL (Step Ladder Programming)

STL programming uses step points, e.g. S0 S21, S22, which allow users to program in a clearer and understandable way as drawing a flow chart. The program will proceed to next step only if the previous step is completed, therefore it forms a sequential control process similar to SFC (Sequential Function Chart) mode. The STL sequence can be converted into a PLC ladder diagram which is called “step ladder diagram” as below.

1.7 Fuzzy Syntax

Generally, the ladder diagram programming is conducted according to the “up to down and left to right” principle. However, some programming methods not following this principle still perform the same control results. Here are some examples explaining this kind of “fuzzy syntax.”

Example 1:

X0 X2 X4

X5X3X1

Better method OK method

LD X0 LD X0 OR X1 OR X1 LD X2 LD X2 OR X3 OR X3 ANB LD X4 LD X4 OR X5 OR X5 ANB ANB ANB

The two instruction programs can be converted into the same ladder diagram. The difference between Better and OK method is the ANB operation conducted by MPU. ANB instruction cannot be used continuously for more than 8 times. If more than 8 ANB instructions are used continuously, program error will occur. Therefore, apply ANB instruction after a block is made is the better method to prevent the possible errors. In addition, it’s also the more logical and clearer programming method for general users.

Example 2:

X0

Good method Bad method

X1

LD X0 LD X0 OR X1 LD X1

X2

X3

OR X2 LD X2 OR X3 LD X3 ORB ORB ORB

The difference between Good and Bad method is very clear. With longer program code, the required MPU operation memory increases in the Bad method. To sum up, following the general principle and applying good / better method when editing programs prevents possible errors and improves program execution speed as well.

Common Programming Errors

PLC processes the diagram program from up to down and left to right. When editing ladder diagram users should adopt this principle as well otherwise an error would be detected by WPLSoft when compiling user program. Common program errors are listed below:

1.9 Basic Program Design Examples

Example 1 - Stop First latched circuit

When X1 (START) = ON and X2 (STOP) = OFF, Y1 will be ON. If X2 is turned on, Y1 will be OFF. This is a Stop First circuit because STOP button has the control pri ority than START

Y1

X1

X2

Y1

Example 2 - Start First latched circuit

When X1 (START) = ON and X2 (STOP) = OFF, Y1 will be ON and latched. If X2 is turned ON, Y1 remains ON. This is a Start First circuit because START button has the control priority than STOP

Example 3 - Latched circuit of SET and RST

The diagram opposite are latched circuits consist of RST and SET instructions.

In PLC processing principle, the instruction close to the end of the program determines the final output status of Y1. Therefore, if both X1 and X2 are ON, RST which is lower than SET forms a Stop First circuit while SET which is lower than RST forms a Start First circuit.

Example 4 - Power down latched circuit

The auxiliary relay M512 is a latched relay. Once X1 is ON, Y1 retains its status before power down and resumes after power up.

NC contact Y1 is connected to Y2 output circuit and NC contact Y2 is connected Y1 output circuit. If Y1 is ON, Y2 will definitely be OFF and vice versa. This forms an Interlock circuit which prevents both outputs to be ON at the same time. Even if both X1 and X2 are ON, in this case only Y1 will be enabled.

Example 7 - Sequential Control

Example 8 - Oscillating Circuit

An oscillating circuit with cycle ΔT+ΔT

Y1

In the first scan, Y1 turns on. In the second scan, Y1 turns off due to the reversed state of contact Y1. Y1 output status changes in every scan and forms an oscillating circuit with output cycleΔ

When X0 = ON, T0 starts timing (nT). Once the set time is reached, contact T0 = ON to enable Y1(ΔT). In next scan, Timer T0 is reset due to the reversed status of contact Y1. Therefore contact

T0 is reset and Y1 = OFF. In next scan, T0 starts timing again. The process forms an oscillating circuit with output cycle nT+ΔT.

Example 10 - Flashing Circuit

2.6 PLC Bits, Nibbles, Bytes, Words, etc

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

Numeric Description

Bit

Nibble

Bit is the basic unit of a binary number system. Range is 0 or 1 Consists of 4 consecutive bits, e.g. b3~b0. Range 0 ~ 9 in Decimal or 0~F in

Hex

Byte

Word

Consists of 2 consecutive nibbles, e.g. b7~b0. Range 00 ~ FF in Hex

Consists of 2 consecutive bytes, e.g. b15~b0. Range 0000 ~ FFFF in Hex

Consists of 2 consecutive words, e.g. b31~b1. Range 00000000 - FFFFFFFF

Double Word

Bit

For fulllfilling different kinds of internal manipulation, DVP-PLC appies 5 foramts of number systems. Each number system has its specific purpose and function describ ed as below.

1. Binary Number, (BIN) PLC internally calculates, operates, and stores the value in Binary format.

2. Octal Number, (OCT) The external I/O points of DVP-PLC are numbered in octal format.

e.g. External inputs: X0～X7, X10～X17, …, X377. (No. of device)

External outputs: Y0～Y7, Y10～Y17, …, Y377. (No. of device)

3. Decimal Number, (DEC) DVP-PLC appies decimal operation in situations below:

z Set value for timers and counters, e.g. TMR C0 K50. (K value) z No. of S, M, T, C, D, E, F, P, I devices, e.g. M10, T30. (No. of device) z For use of operand in API instru ctions, e.g. MOV K123 D0. (K value)

2-15

DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

z Constant K: Decimal value in PLC operation is attached with an “K”, e.g. K100 indicates the value 100 in Decimal format.

Exception:

When constant K is used with bit devices X, Y, M, S, the value specifed after K indicates the groups of 4-bit unit, which forms a digit(4-bit), byte(8 bit), word(16bit), or double word(32-bit) data, e.g. K2Y10, K4M100, representing Y10 ~ Y17 and M100~M1 15.

4. BCD (Binary Coded Decimal) BCD format takes 1 digit or 4 bits to indicate a Decimal value, so that data of consecutive 16

bits indicates a 4-digit decimal value. Used mainly for reading values from DIP switches or sending data to 7-segement displays

5. Hexadecimal Number, HEX

DVP-PLC appies Hexadecimal operation in situations below:

z For use of operand in API instru ctions, e.g. MOV H1A2B D0。(H value) z Constant H:

Hexadecimal value in PLC operation is attached with an “H”, e.g. H100 indicates the value 100 in Hex format.

2.8 M Relay

The types and functions of special auxiliary relays (special M) are listed in the table below. Care should be taken that some devices of the same No. may bear different meanings in different series MPUs. Special M and special D marked with “*” will be further illustrated in 2.13. Columns marked with “R” refers to “read only”, “R/W” refers to “read and write”, “-“ refers to the status remains unchanged and “#” refers to that system will set it up according to the status of the PLC.

Initial step relay

Starting instruction in Sequential Function Chart (SFC). S0~S9, total 10 points.

Zero return step relay

Returns to zero point when using IST instruction in program. Zero return step relays not used for IST instruction can be used as general step relays. S10~S19, total 10 ponits.

Latched step relay

In sequential function chart (SFC), latched step relay will be saved when power loss after running. The state of power on after power loss will be the same as the sate before power loss. S20 ~ S127, total 108 points.

General purpose step relay

General relays in sequential function chart (SFC). They will be cleared when power loss after running. S128 ~ S911, total 784 points.

Alarm step relay

Used with alarm driving instruction API 46 ANS as an alarm contact for recording the alarm messages or eliminating external malfunctions. S912 ~ S1023, total 112 points.

2.10 T (Timer)

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 associated output coil will be ON. The set value should be a K value in decimal and can be specified by the content of data register D.

The actual set time in the timer = timer resolution× set value Ex: If set value is K200 and timer resolution is 10ms, the actual set time in timer will be 10ms*200 =

2000ms = 2 sec.

General Timer

The timer executes once when the program reaches END instruction. When TMR instruction is executed, the timer coil will be ON when the current value reaches its preset value.

When X0 = ON, TMR instruction is driven. When current value achieves K100, the assocailte timer contact T0 is ON to drive Y0. If X0 = OFFor the power is off, the current value in T0 will be cleared as 0 and output Y0 driven by contact T0 will be OFF.

2. Programming Concepts

Accumulative Timer

The timer executes once when the program reaches END instruction. When TMR instruction is executed, the timer coil will be ON when the current value reaches its preset value. For accumulative timers, current value will not be cleared when timing is interrupted.

Timer T250 will be driven when X0 = ON. When X0 = OFFor the power is off, timer T250 will pause and retain the current value. When X0 is ON again, T250 resumes timing from where it was paused.

Timers for Subroutines and Interrupts

Timers for subroutines and interrupts count once when END instruction is met. The associated output coils will be ON if the set value is achieved when End instruction executes. T184~T199 are the only timers that can be used in subroutines or interrupts. Generals timers used in subroutines and interrupts will not work if the subroutines or interrupts are not executing.

2.11 C (Counter)

Counters will increment their present count value when input signals are triggered from OFFON.

2. Programming Concepts

M relays M1200~M1254 are used to set the up/down counting direction for C200~C254 respectively. Setting the corresponding M relay ON will set the counter to count down.

Example:

LD X10 OUT M1200 LD X11 RST C200 LD X12 CNT C200 K-5 LD C200 OUT Y0

a) X10 drives M1200 to

determine counting direction (up / down) of C200

b) When X11 goes from OFF to

ON, RST instsruction will be executed and the PV (present value) in C200 will be cleared and contact C200 is OFF.

c) When X12 goes from Off to

On, PV of C200 will count up

7. C243 and C244 support count-up mode only and occupy the associate input points X1 and X3 as reset (“R”) function. If users do not need to apply reset function, set ON the associated special M relays (M1243 and M1244) to disable the reset function.

8. “Dir” refers to direction control function. OFF indicates counting up; ON indicates counting down.

9. When X1, X3, X4 and X5 is applied for reset function and associated external interrupts are disabled, users can define the reset function as Rising/Falling-edge triggered by special M relays

Reset Function X1 X3 X4 X5

R/F M1271 M1273 M1274 M1275

10. When X1, X3, X4 and X5 is applied for reset function and external interrupts are applied, the interrupt instructions have the priority in using the input points. In addition, PLC will move the current data in the counters to the associated data registers below then reset the counters.

2. Programming Concepts

1. X21 drives M1235 to determine counting direction (Up/Down) of C235.

2. When X20 = ON, RST instsruction executes and the current value in C235 will be cleared. Contact C235 will be OFF

3. When X22 = ON, C235 receives signals from X0 and counter will count up (+1) or count down (-1).

4. When counter C235 reaches K5, contact C235 will be ON. If there is still input signal inp ut for X0, it will keep on counting.

2.14 E, F Index Registers

Index registers are used as modifiers to indicate a specified device (word, double word) by defining an offset. Devices can be modified includes byte device (KnX, KnY, KnM, KnS, T, C, D) and bit device (X, Y, M, S). E, F registers cannot be used for modifying constant (K, H) Index registers not used as a modifier can be used as general purpose register.

Index register [E], [F]

Index registers are 16-bit registers which can be read and written. There are 16 points indicated as E0~E7 and F0~F7. If you need a 32-bit register, you have to designate E. In this case, F will be covered up by E and cannot be used. It is recommended to use instruction DMOVP K0 E to reset E (including F) at power-on.

16-bit

F0

16-bit

E0

32-bit

The combinations of E and F when designating a 32-bit register are: (E0, F0) , (E1, F1) (E2, F2) (E3, F3) (E4, F4) , (E5, F5) (E6, F6) (E7, F7)

Example:

When X0 = ON and E0 = 8, F0 = 14, D5E0 = D(5+8) = D13, D10F0 = D(10+14) = D24, the content in D13 will be moved to D24.

Nest Level Pointer N: used with instruction MC and MCR. MC is master start instruction. When the MC instruction is executed, the instructions between MC and MCR will be executed normally. MC-MCR master control instruction is nested level structure and max. 8 levels can be applicable, which is numbered from N0 to N7.

Pointer P: used with application instructions CJ, CALL, and SRET. CJ condition jump: When X0 = ON, program will jump from address 0 to N (designated label P1) and keep on the execution. Instructions between 0 and N will be ignored. When X0 = OFF, program will execute from 0 and keep on executing the followings. CJ instruction won’t be executed at this time.

Interrupt pointer I: used with application instruction API 04 EI, API 05 DI, API 03 IRET. There are four types of interruption pointers. To insert an interruption, users need to combine EI (enable interruption), DI (disable interruption) and IRET (interruption return) instructions

1. External interrupt  When input signal of input terminal X0~X7 is triggered on rising-edge or falling-edge, it will

interrupt current program execution and jump to the designated interrupt subroutine pointer I000/I001(X0), I100/I101(X1), I200/I201(X2), I300/I301(X3), I400/I401(X4), I500/I501(X5), I600/I601(X6), I700/I701(X7). When IRET instruction is executed, program execution returns to the address before interrupt occurs.

 When X0 (C243) works with I100/I101 (X1), X0/X1 (C246, C248, C252) works with I400/I401,

the value of C243, C246, C248, C252 will be stored in (D1240, D1241)

 When X2 (C244) works with I300/I301 (X3), X2/X3 (C250, C254) works with I500/I501, the

value of C244, C250, C254 will be stored in (D1242, D1243).

2. Timer interrupt PLC automatically interrupts the currently executed program every a fixed period of time

(2ms~99ms) and jumps to the execution of a designated interruption subroutine

3. Counter interrupt The high-speed counter comparison instruction API 53 DHSCS can designate 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 ,I060, I070, I080..

4. Communication interrupt I140:

Communication instruction RS (COM1 RS-232) can be designated to send interrupt request when specific charcters are received. Interrupt I140 and specific characters is set to low byte of D1167.

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

2-53

DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

communication. Set up the specific end word in D1167 and write the interruption subroutine I140. When PLC receives the end word, the program will execute I140.

I150: Communication instruction RS (COM2 RS-485) can be designated to send interrupt request when specific charcters are received. Interrupt I150 and specific characters is set to low byte of D1168. This function can be adopted when the PLC receives data of different length during the communication. Set up the specific end word in D1168 and write the interruption subroutine I150. When PLC receives the end word, the program will execute I150..

I160: Communication instruction RS (COM3 RS-485) can be designated to send interrupt request when specific charcters are received. Interrupt I160 and specific characters is set to low byte of D1169 This function can be adopted when the PLC receives data of different length during the communication. Set up the specific end word in D1169 and write the interruption subroutine I160. When PLC receives the end word, the program will execute I160

Monitor Timer D1000

Contents:

1. Monitor timer is used for moitoring PLC scan time. When the scan time exceeds the set value (SV) in the monitor timer, the red ERROR LED will be ON and all outputs will be “OFF”.

2-55

DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

2. The default in the monitor timer is 200ms. If the program is long or the operation is too complicated, MOV instruction can be used to modify SV. See the example below for SV = 300ms.

M1002

0

Initial pulse

MOV K300 D1000

3. The maximum SV in the monitor timer is 32,767ms. However, care should be taken when adjusting SV. If SV in D1000 is too big, it cost much longer for operation errors to be detected. Therefore, SV is suggested to be shorter than 200ms.

4. Scan time could be prolonged due to complicated instruction operations or too many I/O modules being connected. Check D1010 ~ D1012 to see if the scan time exceeds the SV in D1000. Besides modifying the SV in D1000, users can also apply WDT instruction (API 07). When program execution progresses to WDT instruction, the internal monitor timer will be reset and therefore the scan time will not exceed the set value in the monitor timer.
