12.Motor forward and reverse

This case uses three input terminals for control buttons, the forward and reverse rotation of the belt is used as an example

13.Multi-PLSY

This case uses three instructions “CJ”and “PLSY”,to control that bell ringing.Two bell’s voice are different. When customer press bell button,bell will ring that means customer coming.Voice is two short ringtone. When window broken,“windows sensor will trigger X2”.bell will ring that means warning.Voice is long high ringtone.

14.PLSY instruction for illumination control

This case change the the brightness of light by changing the frequency of pulse.

15.Reset all device

This case uses “ZRST” to reset many device(for example: traffic lights).Because PLC steps capacity is limited. ZRST can reset many device to save capacity. There are many lights. PLC will control these lights with Y0-Y17.ZRST can close these lights quickly.

16.Start, hold, Stop of motor

This case uses the motor start, hold and stop control as an example that demonstrates how to use the LD, LDI instruction.

17.Two-way traffic lights at crossroads

This case uses PLC output(Y) as light control, and use traffic lights as an example.

18.Using ALT start or stop one action

The timing of an event can be controlled by an input, using this input to switch the timer ON state to the OFF state.

19.Variable control of PLSY instruction

Users can change the sound of the doorbell by raising or lowering the pulse that drives the doorbell.

20.PID

A proportional–integral–derivative is a control loop feedback mechanism commonly used in industrial control systems. PID control continuously calculates an error value as the difference between a measured process variable and a desired set point.

In this demo,user could use HMI and PLC to simulate,and image this is heating temperature device,and you can use HMI to simulate this test environment.

1.Set a target value in HMI screen.SV

2.Set the PV by + and - button

3.If the PV > SV then,then PID output will stop,and then PV will reduce(you can click - to reduce PV) until PV<SV.then PID parameter will be generated

4.Then user can continue this progress until PID parameter stable.Then user can fine-tune PID parameter to make more stable.

5.After getting a stable PID parameter,user can close self turning function,and use these PID parameter directly.Only environment do not change,PID also do not need to change
