1.2 Concept of the Sequence Programming

The so-called sequence programming is the one that performing the logic control to the

machine tool and its relative equipments.

After the programming is converted into some kind of format, CPU can be performed its code

and calculation treatment for it, and its fruits can be memorized to RAM. CPU can be rapidly read

each code stored in the memory, which can be performed the programming according to the

calculation operation.

Page 19

Chapter One Squency Programming Compilation Schedule

The compilation of the sequence programming starts with the ladder diagram.

1.3 Distribution Interface (Step one)

The interface can be distributed after confirming the control object and calculating the points of

the corresponding input/output signal.

Refer to the Chapter Four Input/output interface signal table in the Volume Four Installation and

Connection when distributing the interface.

1.4 Ladder Diagram Compilation (Step two)

The required control operation can be expressed by the ladder diagram with the on-line

Volume I Programming

compilation of the Gsk218MC series ladder diagram. The functions, such as the timer and counter,

can not be expressed by relay symbols, which can be indicated by the specified function code

symbols.

The compiled ladder diagram should be stored and converted into the corresponding PLC

codes before operating, namely, the so-called instruction list.

1.5 Sequence Programming Debugging (Step 3)

The sequence programming can be debugged using the following methods:

Debugging with emulator

The machine tool can be replaced by an emulator (it composes of the lights and switches).

ON/OFF of the switch means the signal input state of the machine tool, and the ON/OFF of

the light is the signal state output.

Debugging with actual operation

Debug on the actual machine tool. It is better to prepare the precautions before debugging,

otherwise an unexpected behavior may occur.

Chapter Two Sequence Programming

CHAPTER TWO SEQUENCE PROGRAMMING

The operation principle is different with the common relay circuit, because the PLC sequence

control is carried out by compiling the on-line diagram; and therefore, it is better to thoroughly

comprehend the sequence control principle when designing the PLC sequence programming.

2.1 Performance Process of Sequence Programming

In the general relay controlling circuits, each of them can be simultaneously operated. When the

relay A is operated in the following figure, the replay D and E can be operated (when the contactor A

and B are entirely closed) at the same. Each replay in the PLC sequence control is operated in turn.

The relay D is operated before relay A, and then the relay E operates (refer to the following figure).

Namely, each relay is operated based upon the sequence of the ladder diagram (compilation

sequence).

Fig. 2.1 (a) Circuit illustration

The differences between the relay circuit and PLC programming operation are shown below in

the Fig. 2.1 (b) and Fig. 2.1 (c).

Volume I Programming

Fig. 2.1 (b)

Page 22

GSK218MC Series Machining Center CNC System PLC & Installation Connection Manual

(1) Relay circuit

Both Fig. 2.1 (b) and Fig. 2.1 (c) are shared a same operation. B and C are switched on after A

is turned on. B is cut off after C is ON.

Volume I Programming

(2) PLC program

A same relay is shared a same circuit, refer to the Fig. 2.1 (b); B and C are switched on after A

is turned on. B is cut off after one cycle of the PLC program is performed. In the Fig. 2.1 (c), C is ON

instead of B, after C is turned on.

2.2 Cycle Performance

Fig. 2.1 (c)

PLC performs from the beginning to the end of the ladder diagram. It performs again from the

beginning of the ladder diagram after this diagram is performed, which is called cycle performance.

The performance time from the beginning to the end of the ladder diagram is abbreviated as a

period of a cycle treatment. The shorter of the treatment period is, the stronger of the response

capacity of the signal is.

2.3 Priority Sequence of the Execution (the 1st Level, the 2nd level)

GSK218MC Series PLC program are composed of two parts: the 1st level program and the 2nd

level program, which are inconsistent with the performance period.

The 1

required for fast response.

The 2

PLC may divide the 2nd level program into N parts when the 2nd level program is executed. It is

level program performs once each 8ms, which can be treated the short pulse signal

program performs once each 8*nms. N is the partition number of the 2nd level program.

performed one part for each 8ms.

PLC in the GSK218MC series is separately performed in the PLC-AVR SCM. The 1ms of each

8ms is the communication time for reading the PLC data from the CNC. The 5ms is that the PLC

gains the system control signal (F, X), and uploads the control result data (G and Y parameters)

external port I/O (X and Y). PLC is always performed the ladder diagram calculation other than the

interruption of the response exchange data.

Volume I Programming

Fig. 2-3-2

When the last partition number of the 2

level program of the n is performed, the program then executes from its beginning. In this case, when the partition number is n, the performance time of one cycle is 8*n ms. The 1st level program performs once each 8ms; the 2nd level program performs once

each 8*n ms. If its steps of the 1

level program is increased, and therefore the steps of the 2nd level

program within 8ms should be reduced correspondingly; the partition number may be increased, and the treatment time of the overall programs will be longer. So, the compilation of the 1

level program

should be shorter.

2.4 Sequence Program Structure

The ladder diagram compiles in turn in the traditional PLC. However, it owns the following

advantages in the ladder diagram language allowing the structured programming:

1. The program is easy to comprehend and compile.

2. It is more convenient to find the faults during the programming.

Page 24

3. It is easy to find some reasons when the operation malfunction occurs.

There are 3-kind of structuring programming methods:

Sub-program

The subprogram is regarded as a treatment unit based on the ladder diagram.

2.5.2 Treatment of the Output Signal

(1) NC output register

The output signal transfers to the NC output register from the PLC each 8ms.

(2) Machine tool output register

The signal memorized in the machine tool output register conveys to the machine tool each

8ms.

Note: The signal states, such as the NC input register, NC output register, machine input register and machine

output register, which can be displayed by the self-diagnosis function. The diagnosis number is the address

number in the sequence programming.

2.5.3 Distinguish of Signal State Between 1st Level and 2nd Program

As for the same input signal, their states may different between the 1st and 2nd level

programming, that is the reason that different registers are used between two levels programming.

Namely, the input signal used with the 2

therefore, the signal in the 2

level program is later than the 1st level one. At the worst case, one 2nd

level program is the one of the 1st level who is locked. And

level program performance cycle can be lagged.

It is better to remember this point when programming the ladder diagram.

therefore, the 2

level program is completed.

A turns into 0 to perform the 1

latched as the one last time. So, C=1.

In this way, the state both B and C are different.

2.6 Interlocking

In the sequence control, the interlocking is very important from the safety issue.

It is necessary to use the interlocking in the sequence control programming. Simultaneously,

the hard interlocking is used in the relay control circuit of the strong electric cabinet of the machine

tool sides. This is the reason that the interlocking is disabled when the hardware of the performance

sequence programming malfunctions, even if the interlocking is logically used in the sequence

program (software). And therefore, the interlocking can be ensured the safety for the user, and

prevent the machine tool from damaging in the strong electric cabinet of the machine sides.

CHAPTER FOUR PLC BASIS CODE

The design of the sequence program begins from compiling ladder diagram. The ladder

diagram consists of relay contact and function code. The logic relationship in the ladder diagram

composes of sequence program. There are two methods of the sequence program input: one uses

the mnemonic symbol language (The system is not temporarily supported the PLC command code

of the RD, AND and OR); the other one is used the relay symbol. The programming can be compiled

using ladder diagram instead of comprehending the PLC code based upon the latter.

Actually, the sequence program inside the system can be converted into corresponding PLC

code even if it is input by the relay symbol.

The basis codes are commonly used one when designing the sequence programming, which

are performed one-digit calculation.

The basis command codes of the GSK218MC series are shown below:

divides into three types: the only one ladder diagram in operating, the rest of 15 ladder diagrams

other than the operation of the ladder diagram 0—15 and the other ladder diagrams for compiling

and reference (Any two numbers can be identified or named other than 0-15).

(2) The value of the system is set by bit parameter 53#0~#3 when the power is turned on

initialization, which is the composed parameter of binary system; the No. 0 ladder diagram is

used when this value is set to 0; when this value is set to 1~15, the No. 1~15 ladder diagrams

are then used. The ladder diagram file for loading some one number is called operation file (this

operation may cause hazard; it is enabled after restarting when the power is turned off). This

file may be deleted to rebuild if the format is incorrect. So, the user should carefully specify the

file name of the ladder diagram. The overall file names of the ladder diagram must be

“ladderXX.grp” (XX is number), otherwise, the files may not be identified by the system. The file

format is described by the system, the user can not modify it without the system; otherwise, it

may be deleted or can not be identified.

(3) M6 is separately called the macro program from O91000 to O91015 when the 0~15 ladder

diagrams are used.

(4) The selection of the ladder diagram. The file name can be specified by moving the cursor or

inputting the “LX”/“LXX” (X/XX is number). The system may detect whether the X”/“XX is the

known file name by pressing the “input” key. If it does not detect, the ladder diagram file should

be set up based upon the file name “ladder0X.grp” or “ladderXX.grp”. The system may

automatically generate two function blocks “END1” and “END2” when the new file is set up, so

that the user can consecutively operate this ladder diagram file (The command table remains

null if it is converted after opening the file). User can copy or cut the ladder diagram from the

normal file (it can not exceeds 100 rows, otherwise, only the previous 100 rows can be

performed) pasting to other file, then copy the function (without modification), and then set up a

new file. For safety’s sake, after the ladder diagram is compiled, the current file may

automatically stored when another file is opened; the ladder diagram syntactic may be detected

before storing of which it may give up if the incorrect syntax is found.

(5) The file header includes the basis information of the file such as the line number and step

number, wherein, the step information occurs as long as it is converted, otherwise, it always

keeps the opening information. User can delete the unopened and unoperated ladder diagram

file; this operation is the irreversible operation, so user should be careful. The system may stop

the renewal of the ladder diagram network after the user open the unoperated ladder diagram,

in order to avoid the misguidance. The operating ladder diagram can only be stored and copied,

so that user can copy this information to others ladder diagram files. It is better to stop the

operation before compiling the current ladder diagram. When the cursor stops at the

background compiling file, user can open the Info information to modify the compiling file
