Summary of XC series PLC
This manual includes some basic precautions which you should follow to keep you safe and
protect the products. These precautions are underlined with warning triangles in the manual.
About other manuals that we do not mention please follow basic electric operating rules.
Precautions
Please follow the precautions. If not, it may lead incorrect or
abnormal the control system, even cause fortune lose.
Correct
Application
The models could only be used according to the manual, and can
only be used along with the peripheral equipments recognized or
recommended by Xinje Electronic. They could only work
normally in the condition of be transported, kept and installed
correctly, also please operate and maintain them according to the
recommendations.
We have checked the manual; its content fits the hardware and software of the products. As
mistakes are unavoidable, we couldn’t promise all correct. However, we would check the data in
the manual frequently, and in the next edition, we will correct the necessary information. Your
recommendation would be highly appreciated.

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”.

Summary of XC series PLC
1. Summary of XC series PLC
XC series PLC are mini type PLC with powerful function. These series products can satisfy
diverse control requirement. With compact design excellent extend capability, cheap price and
powerful function, XC series PLC has become perfect solution of small size control.

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.

z Input terminal
When connect input terminal and COM terminal with contacts without voltage or
NPN open collector transistor, if input is ON，LED lamp lights, which indicates input。
There are many COM terminals to connect in PLC.
z Input circuit
Use optical coupling instrument to insulate the input once circuit and twice circuit，
There’s a C-R filter in the twice circuit。It is set to avoid wrong operation caused by
vibration of input contacts or noise along with input signal. As the preceding reason, for
the changing of input ON→OFF，OFF→ON，in PLC, the response time delays about
10ms。There’s a digital filter inside X000~X015。This kind of filter can very from
0~15ms according to the special register (D8020).
z Input sensitive
The PLC’s input current is DC24V 7mA，but to be safe，it needs current up to 3.5mA
when it’s ON，lower than 1.5mA when it’s OFF.

Relay output circuit
z Output terminals
Relay output type includes 2~4 public terminals. So each public-end unit can drive different
power-voltage system’s (E.g.：AC200V，AC100V，DC24V etc.) load.
z Circuit’s insulation
Between the relay output coils and contacts，PLC’s interior circuits and exterior circuits, load
circuits are electric insulation. Besides, each public-end blocks are separate.
z Action display
LED lamp lights when output relay’s coils galvanize, output contacts are ON.
z Response time
From the output relay galvanize (or cut) to the output contacts be ON (or OFF), the response time is
about 10ms
z Output current
The current-voltage below AC250V can drive the load of pure resistace 2A/1 point、inductance load
below 80VA（AC100V or AC200V） and lam load below 100W（AC100V or AC200V）.
z Open circuit’s leak current
When the output contact be OFF and there’s no leak current，can directly drive Ne lamp etc.
z The life of relay output contacts
Standard life of induce AC load such as cont ctor、electromagnetism valve：5 million times for
20VA load. Cut power device’s life according t the company’s test: for 80VA load, the action life is
up to 2 million times. But if the load parallel nnect with surge absorber, the life will be greatly
improved!
