Summary of XC series PLC

Preface

—— Specialties of programmable controller

The programming of XC series programmable controller has the following characteristics:

• Support two kinds of program languages

In XC series PLC, besides statement format, you can also adopt ladder chart on the

screen and these two formats could convert to the other.

• Rich basic functions

Based on the theory of “Basic functions, High speed dispose, convenient to use”, XC

series PLC supports not only functions relative to sequence control, but also basic

application instructions of data transfer and compare, arithmetic and logic control

loop and shift of data etc., besides, it can support interrupt, high-speed counter

exclusive compare instructions, high-speed impulse output and other high-speed

dispose instructions.

• Offset function (Indirect addressing)

Add offset suffix after the coil, data register (e.g. X3[D100], D0[D100]) to realize

indirect addressing. E.g. when D100=0, X3[D100] means X3, D0[D100] means D0;

when D100=9, X3[D100] means X14, D0[D100] means D9;

• Single phase or AB high speed counter

The high speed counters in XC series PLC carry on interrupt disposal with the high

speed pulse from special input points. So it is independent with the scan cycle, the

count speed can reach 200 KHz.

• Convenient MODBUS communication instructions

With Modbus communication instruction, PLC can easily communicate with every

kind of peripheral device as long as they have Modbus protocol.

• High speed pulse output

The main units have two routes pulse output, output can be sequencial segments, and

each segment of pulse number could be set freely. The pulse could reach 400 KHz

XC series PLC are divided into XC1, XC3 and XC5 sub series:

• XC1 economic type: This sub-series has specifications of 16 I/O, 24 I/O and 32 I/O.

The function is simple, suitable for common, small scale applications. They don’t

support high speed count, pulse output, free communication these advanced functions;

also they can not connected with the expansions. For the details, please refer to the

appendix 8-3 “XC1 using description”.

• XC3 Standard type: This sub-series belongs to the standard models of XC series

PLC. They could fulfill most using requirements. If no special demonstrate, this

manual’s content are all written for XC3 series PLC.

• XC5 strength type: This sub-series has specifications of 32 I/O, 48 I/O and 60 I/O.

Besides the functions of XC3-PLC, XC5-32 has function of 4 channels pulse output,

XC5-48, XC5-60 support CANBUS instructions, they can realize CAN bus network

function. For the details, please refer to the appendix 8-4 “XC5 using description”.

z I/O 14~60 points
z FlashROM memory inside
z Real time clock: With clock inside, Li battery power drop memory
z Multi-COM ports can connect with inverters, instruments, printers etc.
z Rich instructions, convenient to program

Statement Program

Statement program is the format which use“LD”, “AND”, “OUT”
etc. These SFC instructions to input this format is the basic input
form to compile the SFC program
E.g: Step Instruction ID

0 LD X000
1 OR Y005
2 ANI X002
3 OUT Y005

Ladder Program

Use sequencial control signal and soft unit’s ID to draw the
sequencial circuit’s graph on the screen, which is called ladder
program. As this method uses trigger point’s symbols and coil
symbols to denote the sequencial control circuit, so it is easy to
understand the program’s contents. At the same time it’s also
available to monitor the PLC’s action via the status displayed in the
circuit.
E.g:

X0 X2

Y5

Y5

The programs compiled with the preceding two methods are both
stored in the PLC’s program memory in the format of instruction
table. So, the denotion and edition of this two program format can
convert to the other.

Function of each device

3-1. Every Soft Unit of Programmable Controller

In the programmable controller, there are many relays、timers and counters，they all have
countless “a” contacts（Normally open contacts）and “b” contacts（Normally closed contacts），

Connect these contacts and coils to constitute sequencial control circuit. The following, we’ll

briefly introduce each soft unit:

【Input（X）and output（Y）relay】

z In each basic unit， assign the ID of input relay, output relay in the format of

X000~X007，X010~X017…,Y000~Y007，Y010~Y017… this octal format. The ID of

extension is connected behind basic unit.

z The ID of expansion obeys the principle of channel 1 starts from X100/Y100, channel 2

starts from X200/Y200… 7 expansions could be connected totally.

z Use digital filter in the special input filter of input relay, so you can use the program to

change the sieve value. So in the high-speed receive application, you can assign this type

of relay’s ID No.

【Auxiliary relay（M）】

z Auxiliary relay is the relay inside the programmable controller，this type of output relay

is different from input/output relay，it can’t gain exterior input，it also can’t drive exterior
load，it can only be used in the program。

z The relay used for retentive can still save its ON/OFF status in the case of PLC power

cut.

【Status（S）】

z Relay used as step ladder chart.
z When not used as working procedure No.，it’s the same with auxiliary relay and can be

used as common contact/coil to carry on programming. Besides, it can also be signal

alarm to diagnose exterior trouble.

【Timer（T）】

z Timer could carry on plus operation to 1ms，10ms，100ms etc. time pulse in PLC, When

reach certain set value, output contact act.

z T100~T199 are timers with the unit of 100ms clock pulse，their current values are the

accumulate values. So, even though timer coil’s drive input is cut, they will still hold the

current value, go on accumulating the action.

32

Function of each device

【Counter（C）】

z The counters can be divided into the following sorts according the their usage and

purpose：

[Used for interior count] Common use / power failure retentive use
16 bits counter：Used for plus count，count bound: 1~32,767
32 bits counter：Used for add / minus count，count bound: -2,147,483,648~+2，

147,483,647

These counters are used for PLC’s interior signals, usually their response speed is below

10Hz.

[Used for high-speed count] For power failure retentive use

32 bits counter: For plus / minus count, count bound: -2,147,483,648~+2,147,483,6487

(Single phase plus count，single phase plus/minus count，AB phase

count) allocate to the special input points.

High-speed counter can count with the frequency below 200kHz，independent with the

PLC’s scan cycle.

【Data register（D）】

z Data register is the soft unit used by data register to save data. XC series PLC’s data

registers are all 16 bits (The high bit is the sign bit), Combine two registers can carry on

32 bits data disposal (The high bit is the sign bit).

Just the same with other soft units, data registers can also be divided to be two types: for

common use and power failure retentive use.

【Constant（K）、(H)】

z In the diverse value used by PLC, K means decimal integer，H means Hex. Value. They

are used to be the set value and current value for the timer and counter, or applied

instructions’ operands.

【Pointer（P）（I）】

z Pointers are used for branch and interrupt. The pointer (P) used by branch is the jump

aim used for condition jump or subroutine jump. Pointer used for interrupt is used for the

assigned input interrupt, time interrupt.

3-3. Data Disposal of Programmable Controller

According to different usage and purpose, XC series programmable controllers use 5 types of
count format. For their usage and function, see the following：

《DEC》（DEC：DECIMAL NUMBER）

¾ The set value of timer and counter（K constant）
¾ The ID of auxiliary relay（M），timer（T），counter（C），status（S）（Soft

unit’s number）

¾ Assign the value in the operands and instruction’s action（K constant）
《HEX》（HEX：HEXADECIMAL NUMBER）

¾ The same with DEC data，it is used to assign the value in the operands and

instruction’s action（H constant）

《BIN》（BIN：BINARY NUMBER）
¾ Just as said before，carry on data allocation to timer, counter or data register in

the format of DEC. or Hex., But in the PLC, these data are all be put in the

format of binary data. And, when carry on monitor on the peripherial device,
these soft units will auto switch to be DEC. data as shown in the graph.（they
can also switch to be Hex. Data.）.

《OCT》（OCT：OCTAL NUMBER）
¾ The input relay, output relay’s soft units’ ID of XC series PLC are allocate in

the format of OCT data. So, it can go on carry of [1-7，10-17，．．．70-77，

100-107].

《BCD code》（BCD： BINARY CODE DECIMAL）
¾ BCD is the method which use 4 bits binary to denote decimal 0~9. It’s easy to

despose bit. So, BCD is available to denote digital switch or 7 segments display

control.

《Other data（float）》
¾ XC series PLC has the function of high precision floating point operation. Use binary

floating point data to execute floating point operation, use decimal floating value to

execute monitor.

 Input disposal

Before PLC executing the program, read all the input terminal’s ON/OFF status of PLC to

the image area. In the process of executing the program, even the input changed, the content

in the input image area will not chang

read out the change.

 Output disposal

Once finish executing all the instructions, transfer the ON/OFF status of output Y image

area to the output lock memory area. This will be the actual output of the PLC. The

contacts used for the PLC’s exterior output will act according to the device’s response

delay time.

When use this input/output f

ormat in a batch, the drive time and operation cycle of input

《Not accept narrow input pulse signal》

PLC’s input ON/OFF time should be longer than its loop time. If consider input filter’s
response delay 10ms, loop time is 10ms，then ON/OFF time needs 20 ms separately. So, up to
1，000/（20+20）=25Hz input pulse can’t be disposed. But, this condition could be improved

when use PLC’s special function and applied instructions.

When executing dual output (use dual coil),

the back side act in prior

As shown in the left map, please consider

the things of using the same coil Y003 at

many positions:
E.g. X001=ON，X002=OFF

At first, X001 is ON, its image area is ON,

output Y004 is also ON.

But, as input X002 is OFF, the image area

of Y003 is OFF.

So, the actual output is : Y003=OFF,

Y004= ON.
