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 orAB 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”.
