Mitsubishi PLC program examples explain -

And share some mitsubishi program, mainly including electric forward control, operations control, timing control, more control, timer and counter combination to extend the timing control, multiple output control and alarm control is implemented by PLC diagram and ladder diagram of PLC, the PLC introduction to beginners need to master the basic knowledge of actual combat.

1, starting, self-locking and stop the control circuit of PLC and trapezoidal chart

starting, self-locking and stop control is the basic of the PLC control function. Starting, self-locking and stop the control can be used to drive instructions ( ) , also can use setting instructions ( 集,RST) To implement. Pieces

driven by coil instruction starting, self-locking and stop the control circuit of PLC and trapezoidal chart

figure 1 driven by coil instruction starting, self-locking and stop the control circuit of PLC and trapezoidal chart

Settings reset instruction was adopted to realize starting, self-locking and stop control of ladder diagram

figure 2 position reset instruction was adopted to realize starting, self-locking and stop control circuit of PLC and PLC ladder diagram

the wiring diagram is the same with the above lines.

2, positive and reverse interlocking control circuit of PLC and trapezoidal chart

figure 3 positive and reverse interlocking control circuit of PLC and trapezoidal chart

3, more control circuit of PLC controller and trapezoidal chart

figure 4 more control circuit of PLC and trapezoidal chart

single as much control as shown in figure a, b, people have more control as shown in figure a and c.

4, timing control circuit of PLC and trapezoidal chart

delay starting timing operation control circuit of PLC and trapezoidal chart
