Xinje PLC programming Lessons

Soft Components :

There are many relays, timers and counters inside PLCs. They all have countless
NO (Normally ON) and NC (Normally Closed) contactors. Connecting these contactors with
the coils will make a sequential control circuit

Input Relay ( X )

Usage of the input relays

The input relays are used to accept the external ON/OFF signal, we use X to state.

2 .Address Specify Principle

In each basic unit, specify the ID of input relay, output relay in the form of X000~X007，X010~X017…,Y000~Y007，Y010~Y017… (octal form).

The expansion module’s ID obeys the principle of channel 1 starts from X100/Y100, channel 2 starts from X200/Y200… 7 expansions can be connected in total

3. Points to pay attention to when using:

For the input relay’s input filter, we use digital filter. Users can change the filter parameters via relate settings.

PLCs are equipped with with more relays than are required for the input/output points, these can be utilized as auxiliary relays, program as normal contactors/coils.

Output Relay ( Y )

Usage of the output relays

Output relays are the interface of drive external loads, represent with sign Y;
2. Address Assignment Principle

In each basic unit，assign the ID of output relays in the form of Y000~Y007, Y010~Y017… this octal format.
The ID of expansion obeys the principle of: channel 1 starts from Y100, channel 2 starts from Y200… 7 expansions could be connected totally
