1.2 STRUCTURE of SEQUENTIAL PROGRAM
Sequential program is defined to logically control the machine and relative devices according to sequence of ladder. The sequence of ladder is compiled in a traditional PLC but GSK980TD CNC PLC is integrated by traditional one and advanced structured programming, employed with subprogram, embedded subprogram and conditional branch and with apparent advantages compared to the traditional.
Programming 1 Book
1.2.1 Subprogram
In GSK980TD CNC PLC program, a special subprogram can be called according to requirements of programming. For example, subprogram P0001 can be called when contactor X0000.0 is closed as follows:

1.2.2 Subprogram Embedding
Call subprogram P0001
Subprogram P0001
GSK980TD CNC PLC can realize 20 grades subprogram embedding as the following figure. Subprogram P0001 can be called when contractor X0000.0 is closed in main program; subprogram P0002 can be called when contractor X0002.0 is closed in the subprogram P0001.
Subprogram P0001
Subprogram P0001
Call subprogram P0002
-2
Chapter 1 Sequential Program
Subprogram P0002
1.2.3 Conditional Branch
The system can judge whether the setting conditions to execute a corresponding subprogram are satisfactory when a main program is executed circularly, otherwise the system executes subprograms in order as the above-mentioned figure.
Programming 1 Book
1.3 EXECUTING SEQUENTIAL PROGRAM
The edited sequential programs(ladder program)are downloaded to 980TD by serial, CNC reads the ladder and converts into some format identified by it after it is switched on again, and then CPU decodes and operation processes them to store into RAM, and last reads every instruction in memory to execute it by arithmetical operation.
1.3.1 Execution Process of Sequential Program
PLC sequence control is executed by software and there is different from general relay circuit, and so its method is understandingly considered in editing PLC sequential programs.
Every relay can output simultaneously for general relay control circuit as the following figure. Y0002.3 and Y0002.5 output simultaneously when contactor X0000.0, X0002.0 and X0002.2 are closed; in PLC sequence control, every relay outputs in order. For example, Y0002.3 outputs and then Y0002.5 does when X0000.0, X0002.0 and X0002.2 are closed, namely, outputs are executed in order as ladder.

1.3.2 Cycle Execution of Sequential Program
Cycle execution of sequential program is defined that PLC executes ladder from its home to end, and again from its home to end after the run is completed.
Processing cycle is defined to runtime of ladder from home to end. The shorter the processing cycle is, the stronger the response of signal is.
1.3.3 Priority Order of Executing Sequential Program
GSK980TD PLC programs are divided into grade one and grade two programs which processing cycles are different. The first one is executed per 8ms to do with short pulse signal with quick reaction, and the second one is executed per 8n(ms),in which n is fraction times. PLC divides the grade two program into n blocks according to runtime, and executes one block per each 8(ms).
End of grade one program
Fraction 1: 0004 0006
Fraction 1: 0007 0011
End of grade one program
Fraction of the grade two program is to execute the first and execution process is as the following figure when the fraction number is n; T11, T12, T1n are runtime to execute the first. T21, T22, T2n separately corresponds to runtime of No. n block in executing the second when No. n cycle is execute. Tc1, Tc2, Tcn separately corresponds to hold time by CNC when No. n cycle is executed.
The program returns to its beginning to continue execution when the last fraction block of the second is executed completely. The first is executed every 8ms, No. n block of the second is done every 8n, and runtime

of one cycle is 8n(ms). The more the fraction number of the second is, the longer the runtime of one cycle is.

1.4 PROCESSING INPUT/OUTPUT SIGNAL
Processing of input/output signal is as the following figure. X signal of machine I/O interface and F signal of NC are separately input to input memories at machine side and NC side, and directly used by the first grade program; they separately input to synchronous input memories are used by the second. Output signals of the first and the second are separately output to output memories at NC side and machine side and then separately output to NC and I/O interface of machine
Signal states of the above-mentioned memories are displayed by diagnostic interface, and the diagnostic number corresponds to address number of program.

1.4.1 Processing Input Signal
A Input signal of grade one program:
Input memory at NC side is scanned every 8ms and stores F signal from NC, and the system directly use its state when the first is executed.
B Input signal of grade two program:
Input signal of the second is the one stored by the first. The first directly use F and X signal and so the input

GSK980TD Turning Machine CNC System
Programming 1 Book
signal of the second lags the first one and its max. lag time is runtime of one grade two program.
C Difference of input signal states of the first and the second:
For the same input signal, its states are different in the first and the second when PLC reads input signals, because the first reads input memories at NC side and machine side but the second reads the synchronous input memory at NC side and ones at machine side. The input signal of the second lags behind that of the first and its lag time is 8nms which should be noted.
Example
End of grade one program
Fraction1: 0003 0005
Fraction1: 0006 0007
End of grade two program
When the lag time is the first 8ms, X0001.0=1 and the system executes the first Y0001.0=1. When the system starts to execute the second, X0001.0 1 inputs to the synchronous input memory and starts to execute the first block of the fractional second.
When the lag time is the second 8ms, X0001.0=0 and the system executes the first one Y0001.0=1. And then the system executes the second block of the fractional second but X0001.0 =1 which state is still the previous synchronous input memory and Y0002.3=1 after execution.
1.4.2 Processing Input Signal
A Signal to NC
PLC transmits output signal to the output memory at NC side every 8ms, and then directly outputs to NC. B Signal to machine
PLC transmits output signal to the output memory at machine side, and then directly outputs to memory every 2ms.

Chapter 1 Sequential Program
1.4.3 Synchronous Procession of Short Pulse Signal
The first is used for processing the short pulse signal. When it is less than 8ms, namely when the system executes the first, the input signal state may be changed, which may execute programs by mistake.
End of grade one program
As above, X0001.3=0 is changed to X0001.3=1 after Y0002.3=1 is executed, and if the system executes the next line of ladder and Y0003.3=1, at the moment Y0002.3=1 and Y0003.3=1. To avoid the above, process synchronously the short pulse signal as follows:
End of the first grade program
After the program is executed synchronously and when X0001.3=1 Y0003.3=1 Y0002.3=0 X0001.3=0 Y0002.3=1 and Y0003.3=0 but Y0003.3=1 or Y0002.3=1.
1.4.4 Interlock Signal
For safety, the signals must be employed with soft interlock in sequence control, and with hard interlock to relay control circuit of power electric box at machine side at the same time. Because the hardware is failure, the interlock is invalid in executing sequential program even if it is employed logically with soft interlock, which can ensure the operator is not injured and the machine is prevented from damage.

1.5 EDITING SEQUENTIAL PROGRAM
Edit the sequential program from ladder which is composed of relay contacts, symbols and function instructions. Logic relationship in ladder consists of sequential program which is edited by two methods: one is employed with input to use program instructions and the other is with relay symbols by their corresponding contactor, symbol and function instruction. Edit the sequential program employed with the ladder format instead of mnemonic code language when the system is employed with the relay symbol.
In actual editing sequential program, use programming instruction or ladder to edit it according to PLC. In the User Manual, the system is employed with ladder as follows:

ogrammingPr 1 Book
1.5.1 Distributing Interface (Step 1)
The interfaces can be distributed after control target is defined and the corresponding input/output signal points are counted. Refer to input/output interface signal list
1.5.2 Editing Ladder (Step 2)
Edit the software GSKCC.EXE by 980TD ladder to represent the required control operations of machine. Counter, timer which are not done by relay symbol is represented by the specified function instructions. The edited ladder is downloaded to CNC by serial.
1.5.3 Debugging Ladder (Step 3)
After the ladder is downloaded to 980TD, the ladder is debugged as follows:
A emulator
Use one emulator instead of machine to debug it. Machine signal state is represented with switch ON/OFF, and output signal state is done with indicator ON/OFF. Observe if every indicator on the emulator is correct when executing CNC.
B CNC diagnosis
Observe if the diagnostic state of every signal is consistent with the function requirement when executing CNC. Check the ladder by checking each function in order.
C actual run
There may be an unexpected result in the actual debugging machine and so do preventive measures before debugging.
1.5.4 Program Editing Limit
In program, END1 and END2 are needed, which are taken separately as ending character of the first and the second, and END1 must be before END2. The system only supports parallel output instead of multi grades output and there are syntactic errors as follows:

Chapter 2 ADDRESS
Addresses are used for distinguishing signals. Different addresses separately correspond to input/output signal at machine side and CNC side, internal relay, counter, timer, holding relay and data list. An address number is consisted of address type, address number and bit number as follows:
X 0001.6
Bit number
Address number 
Address type
Address type: X, Y, R, F, G, K, A, T, DT, DC, C, D, L, P Address number: decimal number to express one byte
Bit number: octal number, 0 7 separately expressing byte 0 7 bit of front address number
980TD PLC addresses are divided into fixed addresses and definable addresses. Signal definitions of the fixed addresses cannot be changed and are defined by CNC; the definable addresses can be defined again by user according to the actual requirements. Address types are as follows:

2.1 MACHINE→PLC ADDRESS X
980TD PLC X addresses are divided into two types,the first one is X0000.0 X0003.7,which are mainly distributed to CNC XS40 and XS41 I/O interfaces, including fixed addresses and definable addresses,and the second one is X0020.0 X0026.7,which are fixed addresses and mainly be distributed to input keys on operator panel. Other addresses are reserved ones. The value range is 0 or 1.

which can be directly distinguished by CNC in CNC run.
Example: ESP signal is can be connected to X0000.5, CNC directly distinguishes signals on it and judge if there is ESP signal; CNC alarms to emergently stop when G8.4 signal is valid by PLC control.
Namely: CNC alarms to emergently stop when X0000.5 is 0;
CNC alarms to emergently stop when G8.4 is 0 by PLC control.
