2 Soft Component Function
In chapter 1, we briefly introduce the programming language. However, the most important
element in a program is the operands. These elements include the relays and registers. In this
chapter, we will describe the functions and using methods of these relays and registers.
2-1 Summary of the Soft Components
There are many relays, timers and counters inside PLC. They all have countless NO
(Normally ON) and NC (Normally Closed) contactors. Connect these contactors with the
coils will make a sequential control circuit. Next we will introduce these soft components.
 The functions of input relays
The input relays are used to receive the external ON/OFF signal, the sign is X.
 Address AssignmentPrinciple

In each basic unit, X address is in the form of octal, such as X0~X7, X10~X17 …

The extension module address:module 1 starts from X10000, module 2 starts from
X10100…XD1/XD2/XL1 cannot support extension module. Up to 10extension modules
can be connected to the XD3/XL3main unit.
XD5/XDM/XDC/XD5E/XDME/XDH/XL5/XL5E/XLME can connect 16 extension
modules.

Extension BD board: BD 1 starts from X20000;The 24-32 points PLC can connect one
extended BD board and the 48-60 points PLC can connect two extended BD boards. (16-
point PLC does not support extended BD board, XL/XDH series does not support
extended BD board.)

The address number of the left extended ED module, starting from X30000 according to
octal system, XD/XL series PLC supports a left extended I/O ED module. (XDH cannot
support ED module)
 Using notes
The digital filter is used in the input filter of the input relay. Users can change the filter
parameters by setting the special register SFD0, default value is 10ms, modification range: 0
~ 1000ms.
There are enough input relays in the PLC. The input relay whose address is more than input
points can be seemed to auxiliary relay.
 Function of the output relays
Output relays are the interface to drive the external loads, the sign is Y;
 Address Assignment Principle
In each basic unit, Y address is in the form of octal, such as Y0~Y7, Y10~Y17 …
The extension module address: module 1 starts from Y10000, module 2 starts from Y10100…
