Xinje XD Series User Manual

14
XD1/XD2/XL1 does not support extension modules, XD3/XL3 can accept 10 extension
modules, XD5/XDM/XDC/XD5E/XDME/XDH/XL5/XL5E/XLME can accept 16 extension
modules.
Expanding the address number of BD board, starting from X20000 according to octal system,
24-32 points PLC can extend one BD board, 48-60 points PLC can extend two 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 Y30000 according to octal
system, XD/XL series PLC supports a left extended input and output ED module. (XDH
cannot support ED module)
Using notes
There are enough output relays in the PLC. The output relay whose address is more than
output points can be seemed to auxiliary relay.
 Function of Auxiliary Relays
Auxiliary relays is internal relays of PLC, the sign is M and HM;
 Address assignment principle
In basic units, assign the auxiliary address in decimal form
 Using notes
This type of relays are different from the input/output relays, they can’t drive external load
and receive external signal, but only be used in the program;
Retentive relays can keep its ON/OFF status when PLC power OFF;
 Function of status relays
Used as relays in Ladder, the sign is S, HS.
 Address assignment principle
In basic units, assign the address in decimalform.
 Using notes
If it is not used as operation number, they can be used as auxiliary relays, programming as
normal contactors/coils. Besides, they can be used as signal alarms, for external diagnose.
 Function of the timers
Timers are used to accumulate the time pulse like 1ms, 10ms, 100ms etc. when reach the set
value, the output contactors acts, represent sign is T and HT.
 Address assignment principle
In basic units, assign the timer address in decimal form. Please refer to chapter 2-2 for details.
