Page 24: Auxiliary Relay (M)
2-3 Auxiliary Relay (M) The PLC includes considerable internal Auxiliary Relays (M), the function of those are to store up plenty ON/OFF status, which provided data for the processing demand. The operating method of an Auxiliary Relay is the same way to operate the External Output Y, but the contact of Auxiliary Relay can not directly drive an external load.
Page 25: Step Relay (S)
2-4 Step Relay (S) A Step Relay is the basic component in the Sequential Function Chart (SFC) or Step Ladder (STL). The identifier number of a Step Relay S uses the decimal method, and the functions can be divided into four different types: (1) Initial Step Relay It is used in the initial status of the Sequential Function Chart .
Page 26: Timer (T)
2-5 Timer (T) The timers count the time are by increase counting. When the timer's Present Value = Set Value (the value designated to a Timer), the contact of the timer is (ON). The real Set Value of a timer = Designated number × Unit of the timer The set value of a timer can be set directly by using a constant number K or indirectly by using the content value in a Data Registers D or R.
Page 27: Using A Timer In A Subroutine
2-5-3 Using a Timer in a Subroutine When the PLC scans to the coil of an general non-retentive timer (not includs T192~T199), it accumulates or clears the present value of the timer then controls its contact. When the PLC scans to the END instruction, it accumulates or clears the current value of each T192~T199 timer then controls its contact.
Page 28: Counter (C)
2-6 Counter (C) When the pulse input signal in a counter turns from OFF to ON, the present value of the counter will increase (+1 in a up count) or decrease (-1 in a down count) each time, based on the counting types of counters. If the present value equals to set value, the counter's contact turns to be ON.
Page 29: 32- Bit Counter
2-6-2 32- bit Counter The X0 drives the M9200 to define the UP/Down count direction of the M9200 C200. It OFF is defined as an UP count; while ON for Down count. When the counting signal X2 switches from OFF to ON, C200 R S T C 2 0 0 accumulates counting, and the present value in the register alters.

When D0=50, C0 becomes a counter with 50 counts. When D0=200, C0 becomes a counter with 200 counts.
Page 31: Software High Speed Counter
2-7 Software High Speed Counter Each one of the input points X0~X7 in the VS series PLC can be used for high speed function, such as the high speed counter, external interrupt or frequency meter. If a X0~X7 is not designed for high speed function, it can still be used as a general input point.
Page 32: 1-Phase High Speed Counter
2-7-1 1-Phase High Speed Counter The X20 drives the M9235 to define the Up/Down count direction of the C235. M9235 When the X22 is ON, the C235 will receive that count signal from the X0. R S T C 2 3 5 When the signal X21 is ON, the RST instruction is executed.
Page 33: 2-Phase High Speed Counter
2-7-2 2-Phase High Speed Counter When X21 is ON, the C246 receives counting signal from either X0 or X1 R S T C 2 4 6 input point. When X20 is ON, the RST instruction is executed. C246's present value is C246 reset to 0, and its output contact becomes OFF.
Page 34: A/B Phase High Speed Counter
2-7-3 A/B Phase High Speed Counter The A/B phase high speed counter is exclusively for receiving A/B phase pulses from a rotary or linear encoder. When X21 is ON, C251 is activated to receive pulse signals from input R S T C 2 5 1 point X0 (A-phase) and X1 (B-phase).
Page 35: Precautions For Using The Software High Speed Counter
2-7-4 Precautions for Using the Software High Speed Counter The VS series PLC is equipped with the Software High-Speed Counters (SHSC) and the Hardware High-Speed Counters (HHSC).

Page 37: Data Register (D) And Expansion Register (R)
VS series Memory Cards The VS series PLC provides the VS-MC and VS-MCR memory cards. After the installation of a memory card, 655,360 words of latched data storage space are available. Data can be transferred between the data register and the memory in the card via the data bank write instruction DBWR (FNC 91) and the data bank read instruction DBRD (FNC 90).
Page 38: Index Register (V And Z)
2-9 Index Register (V and Z) Index Register V, Z is a very special register in the VS series PLC. Its purpose is to use the index to modify the operand in an instruction, to serve the purpose of specifying the operand indirectly and exchangeable, thereby improving the flexibility and efficiency of program editing.
Page 39: Using Index Register In Application Instruction
2-9-2 Using Index Register in Application Instruction The Index Registers can be used to modify the operand in an application instruction, the modifiable components are shown below: Bit component: X, Y, M, S Pointer: P , Q (P as the label name of the jump or subroutine cannot be modified) Word component: The present value of T and C Index register D, R The KnX, KnY, KnM, KnS which is composed by X, Y, M, S (Kn itself can not be modified)

Page 41: Mark Pointer And Branch Pointer (P)
In the past, the VB series PLC only had Branch Pointer P , which indicates a specific location with indication number, but the program's readability was disadvantageous. Therefore, the VS series PLC newly enhances the Mark Pointer indicator function to enable programmers use illustrative text to indicate a specific address, thus greatly increases the readability.
Page 42: Table Nickname And Table Code (Q)
In order to meet the demands, the VS series PLC has provided the “Table” as a data source form. The table is a data set by collecting data of relevant characteristics, such as data table, MBUS communication table, LINK communication table.
Page 43: Interrupt Pointer (I)
The interrupt, as the name suggests, is to break the sequentially executed program, and then insert a program section to be processed immediately. In the VS series PLC, every Interrupt Pointer is bound up with its interrupt subroutine to interruption.
Page 44 The interruption is a special mechanism for to break the rules of regular operation; an interrupt subroutine is not regularly implemented. Therefore, special attention must be paid to the components that are driven in the interrupt subroutine. If a step relay is for to active a part of the SFC, it is not allowed to be driven in an interrupt subroutine. The following example shows that the elements driven in the interrupt subroutine remain in their state.
Page 45: Numerical System
2-13 Numerical System (1) Binary Number (BIN) The value in PLC is operated and stored used the binary system. The binary number and relative terminology are given as follows: Bit: the basic of the binary number, each value of a Bit must be either “0” or “1”. Nibble: composed of 4 sequential bits.
Page 46 (2) Octal Number (OCT) The assigned numbers of PLC’s external input and output terminals are displayed by the octal system. For example, The external input ports: X0 ~ X7, X10 ~ X17 The external output ports: Y0 ~ Y7, Y10 ~ Y17 (3) Decimal Number (DEC) Decimal Number is the value system which people are familiar with.
Page 47 (7) Floating Point (Real number) The PLC was provided with Floating Point instructions therefore the PLC can calculate decimal numbers. The decimal numbers are storage and calculated in a PLC using two different pattern formats: Binary Floating Point Number and Decimal Floating Point Number. The expositions are showed below. Binary Floating Point Number Inside of the PLC, the Floating Point calculates and decimal number storages are using Binary Floating Point Numbers.

Page 59: The X0~X7 High Speed Input Function Description
2-15 The X0~X7 High Speed Input Function Description The input points X0~X7 of the VS Series PLC have the abilities to respond to high-speed input and to execute many high speed functions. The functions of these 8 output points are listed as follows.
Page 60: External Interrupt
IRET The VS series PLC external interrupt has the function of delay interrupt. That delay time is by the unit of 1ms. This feature allows the user to change the starting of the interrupt subroutine by the parameter adjustments, without to change the external detector's location where the interrupt signal has occurred.
Page 61: Pulse Capture
2-15-2 Pulse Capture The function of pulse capture is to get the input signal which the width of ON is narrow. If an input point X0~X7 is not to use an input special function, its pulse capture is active automatically. The pulse signals which X0~X7 input points capture will reect to the special relays M9170~M9177.
Page 62: Pulse Measurement
2-15-3 Pulse Measurement With the pulse measurement function, the VS series PLC can measure X0, X1, X3, X4 input pulse signal's ON width or cycle period. The pulse measurement function uses an 1/6 µs loop counter to store the count value to the specic special registers at the rising edge and falling edge of the input signal respectively.

Page 64: Hardware High Speed Counter
2-15-4 Hardware High Speed Counter The VS series PLC has two sets of Hardware High-Speed Counter: HHSC1 and HHSC2. To reach the purposes of high-speed counting, the HHSC uses its hardware circuit to get high-speed pulse input. Therefore, in the counting process, HHSC will not affect the efficiency of CPU implementation. When planning a control system, one can make good use of HHSC function.
Page 65 The operating modes of HHSC are illustrated by using the HHSC1. Mode 1: 1-phase Up count Mode 2: 1-phase Up/Down count Up count DIR(X1) Down count U(X0) U/D(X0) HHSC1 HHSC1 Present value Present value Mode 3: 2-phase Up/Down count Mode 4: AB-phase×1 count The encoder is reversed here U(X0) A(X0)
Page 66 Program example: This exemplary program is mainly used to describe the actual usage of the HHSC1 and HHSC2. To use the HHSC, only need to set the counting mode at the special register, then the HHSC can start to count obediently.

4. Sequential Function Chart (SFC) and Step Ladder (STL) In the universe of Automatic Control, the Electro-Control system should work closely with machine movements to get the result of the Automatic Control, i.e. the synergistic integration technology of Mechatronics, which has become popular in recent years.
Page 98: State And Action Of Sfc
4-1-3 State and Action of SFC The VS series PLC uses step relay to indicate the state in the SFC. The diagrams below show the action of step relays under various of situations. S20=OFF, the step is not active, Y7=OFF.
Page 99: Types Of Sfc
In the process of SFC step transferring, there are some phenomena which need to pay special attention to, as the following diagrams show. The step S21 will be executed at the region will not be executed will not be executed will not be executed will be executed :It is a Scan Time, the activated step is transferred at the scan time.
Page 100: Compiling The Sequential Function Chart (Sfc)
4-2 Compiling the Sequential Function Chart (SFC) The SFC has its special operating method. Through the step-by-step description of compiling the SFC program in this chapter, designers can understand the methods of the SFC programming. Here, we use the application example of a fountain in park to explain the design procedure of the SFC in sequence.
Page 101: Convert The Flowchart To The Sfc
4-2-2 Convert the Flowchart to the SFC In an actual application, the external input Turn the READY indicator ON at signals and output loads must be wired to this standby step. the PLC's input and output terminals, therefore it could receive the state of external signal and The START button actually drive the load.
Page 102: Description The Application Types Of Sfc
4-3 Description the Application Types of SFC This section introduces various of processing flow modes about the SFC and the related precautions when to compile it. 4-3-1 Single Flow, Jump and Repeat Flow During the Flowchart Transfer The Single Flow is the basic construction of a SFC and it is used in simple sequential controls. In the actual layout of the SFC, the JUMP instruction (represented by ) is used to specify a jump or repeat about the process of steps ow .
Page 103: Selective Branch And Merge
4-3-2 Selective Branch and Merge Selective Branch : Select one of the branch ows to transfer the effective state. Selective Merge : Merge a number of branch ows into a single ow. The number of available branch ows is 2~8. (no more then 8) When the step relay S10 is effective, its following eight transfer conditions are simultaneously used for to select and move the effective state to either one of the S20, S30, S40, S50, S60, S70, S80 or S90.
Page 104: Special Notices About The Sfc
4-3-4 Special Notices About the SFC The SFC must use the Ladder Masters S (LMS) to compose and join that into the project, then could be loaded and executed at the PLC. There are some rules about the state transfer. The merge operation must direct to a destination step.
Page 105: Precautions About The Composition Of The Sfc
4-4 Precautions About the Composition of the SFC To create an user program for the VS PLC, the Ladder Master S provides the SFC to combine with the original ladder diagram. Be sure to understand its specications and restrictions, in order to use it smoothly and complete the control program correctly.
Page 106 Two non sequential steps can share a timer with the same ID number. Also, it can be set with different set values respectively. K100 Steps S10 and S11 are sequentially connected, the left side T0 is not allowed. Steps S10 and S12 are not sequentially connected, the left side T0 is allowed. The MC and MCR instructions cannot be used in the SFC.
Page 107: Stl / Sfc Relevant Special Components
When a signal is repeatedly used to transfer state at different steps, this signal must be a pulse signal. Also, since the effective state transferring between two sequential steps will cause both of the states ON for a scan time, therefore the prohibitive M1 signal should be added as shown below.
Page 108: The Relationship Between The Sfc And Stl
4-6 The Relationship Between the SFC and STL For to programming a step by step movement program, the VS series PLCs provide SFC and STL to choose from. The relationship between these two methods is described below. 4-6-1 The Step Ladder Instruction (STL)

6-22 Positioning Control Instructions The VS series PLCs are provided with 4 axes control function. Given that to use positing control function is more than understanding positioning control instructions, more professional description is needed. Thus, this manual provides a special chapter 8 “Statement of Positioning Control Functions” for detailed description about the function.

(such as thermostat, inverter, etc.). Therefore, these create a complete control system. Compared to the company's previous products, the VS series PLC has made great progress in increasing the number of communication ports, communication speeds, the exibility of application types and user-friendliness.
Page 362: Notes For Constructing Communication Systems
Terminal device Terminal device All of the VS series communication cards have built-in terminal resistances, user can be enabled the function by short connect the TR terminals. For those communication devices which have no built-in terminal resistances, take special note during wiring to ensure that the external terminal resistance is well connected.
Page 363 Misconception about communication speed. The communication systems are built for various purposes and applications. Most people feel that faster communication means better. In fact, this concept is not necessarily correct. The reason is that faster communication speed relies on the higher communication quality to support, which also means that higher communication construction costs may be required.
