Introduction: Zelio PLC
Zelio PLC is a very interesting controller device from Schneider company and so easy to use and useful if you don't have a time or knowledge with micro controller but it is a little bit expensive comparing with Micro Controller.
there are many type of Zelio PLC depending on Number of input and output, the smallest one shown in below picture.
it contain from :
4 digital input (I1,I2,I3,I4).
4 analogue input from 0-10 volt (IB,IC,ID,IE) .
4 output (Q1,Q2.Q3,Q4).
available power power source (12 ,24 volt DC) and (100,240 volt AC) it depend on your requirement .
the cost of this type about 130 $ plus configuration cable 50 $ .
the software used for this PLC called (Zelio Soft 2) ,it support LDR (ladder language) and FBD (function block diagram) with full simulator.
Step 1: Switch on /Off
This Video showing how to use Zeliosoft to make a simple switch .
a Push button switch connected to I1 and two LEDs in Q1 & Q4 .
Step 2: Analogue to Digital (ADC) Example
in the first circuit I define 5 volt as reference voltage and I compare it with Ib ,so if Ib more than or equal 5 volt ,Q1 will turn on.
in the 2nd circuit I define four reference 5,6,7,8 volt ,so when Ib equal or more than the reference value it will turn on Q1,Q2,Q3 and Q4
Step 3: Impulse Relay Example
I2 connected to magnetometer sensor like for the door sensor ,when the door closed Q3,Q4 turn off ,when door open Q3,Q4 on.
Step 4: Text Example
TX (enable text).
RX (reset text).
Step 5: Counter Example
Step 6: Timer Example
When push button pressed for 3 sec Q4 will turn on.
We have a be nice policy.
