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.
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:

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.

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.
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
rammin
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.

When the lag time is the first 8ms, X0001.0=1 and the system executes the first Y0001.0=1. When the system

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:

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:

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)
rammin
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 indicat or 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

地址号
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:

Chapter 3 PLC BASIC INSTRUCTIONS
Basic instructions are used for editing sequential programs and executing 1-bit operation. There are basic instructions
for GSK980TD PLC as follows:
Instruction
name
LD Read normally-open contact X, Y, F, G, R, K, A
LDI Read normally-closed contact X, Y, F, G, R, K, A
OUT Output coil Y, G, R, K, A
AND Normally-open contact in series X, Y, F, G, R, K, A
ANI Normally-closed contact in series X, Y, F, G, R, K, A
OR Parallel normally-open contact X, Y, F, G, R, K, A
ORI Parallel normally-closed contact X, Y, F, G, R, K, A
ORB Parallel series circuit block
ANB Parallel circuit block in series
3.1 LD，LDI，OUT INSTRUCTION

● Mnemonic code and function
Mnemonic code Function Ladder symbol
LD Read normally-open contact
LDI Read normally-closed contact
OUT Output coil
● Instruction explanation
A: LD, LDI are used for connecting contact to bus bar. Each one can combine with instruction ANB and can be
used at starting point of branch.
B: OUT is used for driving output relay, internal relay coil instead of input relay.
C: Parallel instruction OUT can be continuously used.
● Programming example
Program explanation：
When X0002.1 is 1, the system outputs Y0003.7
When F0100.3 is 0, the system outputs G0120.0

● Instruction explanation
AND, ANI can connect one contact in serial. There can be many contacts in serial and the instructions can be
used many times.
● Programming example
Program explanation：
Use X0002.1,
Use F0100.3 and X0002.1 in series
Use X0008.6, and F0100.3 and X0002.1 in series
If X0002.1=1, X0008.6=1 and F0100.3 is 0, the system outputs Y0003.7.
AND Normally-open contact in series
ANI Normally-closed contact in series
3.3 OR, ORI INSTRUCTION
● Mnemonic code and function
Mnemonic code Function Ladder symbol
OR Parallel normally-open contact
ORI Parallel normally-closed contact
● Instruction explanation
A: OR, ORI can be connected to one contact in parallel. When more than two contacts are connected in series
and the serial loop is connected with other loop in parallel, the system should use ORB.
B: The system executes OR, ORI from its current step with LD, LDI in parallel.

ORB Parallel series circuit block
● Instruction explanation
A: Serial loop block is defined to its loop combined by more than contacts in series. When the serial loop is
connected in parallel, starting point of branch uses LD and its end point uses ORB.
B: ORB is sole instruction without address.

Program explanation：
As above figure, there are three branches(0002,0003,0004) from left bus line to node, and 0002 and 0003 are
serial circuit blocks. There is parallel serial circuit block between bus line and node or among nodes, the
following ending of branch use ORB except for the first one. Use OR instruction if the branch 0004 is not serial
circuit block.
ORB and ANB are instructions without operation function, representing or, and relationship among circuit
blocks.
