DRAGGING A BITMAP IMAGE OR A SUB-PANEL BY MEANS OF THE MOUSE (Primitives):

I made these long ago but never uploaded it on the Forum as I assumed that most everyone knows this trick already.

See the schematic...no explanation required.

Note: Martin made and recently uploaded a schematic in Ruby to drag a Bitmap by means of the mouse (nice).

Nice Tiffy .... thanks !

Simple and good!

I've never needed to do that so far but, if I ever do, I now know how!

Cheers

TRIGGER BUTTON (LIMIT OUTPUT TRIGGERS TO PRESS ONCE):

When the Boolean Switch (True/False) is switched to False (Off) and the Trigger Button is pressed then no corresponding trigger signal can pass through to the Output.

Switching the Boolean Switch to True (On) and then pressing the Trigger Button will allow the corresponding trigger Signal to pass through to the Output.

However, when the Trigger Button has been pressed once no matter how many times the Trigger Button is pressed thereafter the schematic will not allow any further trigger Signals to pass (except for the first trigger signal) to the Output.

To Reset the Schematic the Boolean Switch (True/False) must first be switched to False (Off) and then back to True (On).

The same results can be achieved with a Latch by coupling its output to a Boole to True Trigger, but with fewer components, as shown in the Schematic of Press Once v2.

In the Schematic of Press Once v3, an even simpler method is used with even fewer components.

NOTE: The Trigger Counter and the LED are optional and included for testing purposes only.

TRIGGER BUTTON (LIMIT TRIGGERS TO X-STEPS OR/AND ONCE EVERY X-STEPS):

When the Boolean Switch (True/False) is switched to False (Off) and the Trigger Button is pressed then no corresponding trigger signal can pass through to the Outputs.

Switching the Boolean Switch to True (On) and then pressing the Trigger Button will allow the corresponding trigger Signals to pass through to the Outputs only for the pre-determined X-steps.

However, when the Trigger Button has been pressed for the pre-determined X-steps no matter how many times the Trigger Button is pressed thereafter the schematic will not allow any further trigger Signals to pass (except for the first X-steps) to the Top and Bottom Outputs.

The Top Output will trigger every step only for the pre-determined X-steps and then it will shut off.

The Bottom Output will only trigger once after the pre-determined X-steps and then it will shut off.

To Reset the Schematic the Boolean Switch (True/False) must first be switched to False (Off) and then back to True (On).

TRIGGER BUTTON (LIMIT TRIGGERS TO X-STEPS OR/AND ONCE EVERY X-STEPS) V2 - an even much simpler solution using fewer components.

Set the Required X-Steps in the Properties Panel.

NOTE: The Trigger Counters and the LED's are optional and included for testing purposes only.

Hi Tiffy,

I always like to see your stuff, great work and keep them coming!

SIMPLE ALARM WITH SIREN (EXAMPLE ONLY):

The Boolean Data Component simulates the Doors/Windows Normally Closed (True) Series mechanical Switches.

You enter the Time in Seconds to allow for legally Entering/Exiting whilst the Alarm is Switched On by means of the ON/OFF Button.

With the Alarm Switched OFF, the LED is GREEN. When the Alarm is Switched ON and READY after the Set Time period Elapsed the LED turns RED.

To Switch the Alarm ON or OFF or to RESET you press the ON/OFF Button.

The Alarm has three conditions:

1) DOOR ACCIDENTALLY LEFT OPEN AND ALARM SWITCHED ON:

Door left Open, Alarm Switched ON - Alarm will activate after predetermined Time setting Elapsed (LED turned RED) sounding the Siren.

2) EXITING WHEN ALARM IS SWITCHED ON WHILST LED IS STILL GREEN:

Alarm Switched On and door Opened and Closed within predetermined Time setting (LED still GREEN) for the purpose to Exit without Activating the Alarm.

3) ENTERING LEGALLY WHEN ALARM IS SWITCHED ON AND READY WITH LED TURNED RED:

With the Alarm still switched On and READY (LED turned RED) and Opening the Door for the purpose to Enter will again start the Timer to allow the Alarm to be switched Off within the predetermined Time setting. If the predetermined Time setting has elapsed with the Alarm still switched On, the Siren will sound.

NOTE: ONLY THE ALARM SCHEMATIC IS MY OWN. I DON'T KNOW WHOM TO GIVE CREDIT FOR THE SIREN SCHEMATIC.

Works nice Tiffy.

I'm looking at your 'Exit & Enter Latch' routine. Interesting logic and solution.

I might need to borrow that concept for something I was working on !

4-STAGE SEQUENCE & FULL SPEED STARTUP TIME INTERLOCK WITH AUTOMATIC PRESTART ALARM FOR ELECTRIC MOTORS (EXAMPLE ONLY):

The Schematic ensures that a sequence of Motors are Started up in the correct Sequence as well as ensuring that each motor has reached full speed before the following Motor in the Sequence can be started up thereby saving in Maximum demand Electrical Cost. It also ensures that a Safety warning to personnel is given by sounding the Siren for the predetermined safety time in Seconds when Start Button M1 is pressed, prior to automatically starting up the first motor M1 in the sequence. Currently, only the first Motor M1 starts up automatically after the prestart alarm Siren has stopped sounding and all the Motors following it (M2, M3, M4) has to be started up manually in the correct sequence.

When Start 1 Button for Motor M1 is pressed, it will not start immediately. First, the Automatic Prestart Alarm will be activated and the Siren will sound for the predetermined safety time and when this time has elapsed the Siren will stop sounding and Motor M1 will startup automatically.

Then, only when Motor M1 has reached Full Speed (FS) can Motor M2 be started (Yellow LED on motor M2 Start Button will light up). Each Motors Start Button has two LED's built-in, one Yellow LED and one Green LED. When the Yellow LED on the Next Motor Start Button lights up it indicates that the Motor just prior to it has reached Full Speed and that the motor following it is Ready for Startup. The Green LED indicates that a Motor has been Started. Thus when the Yellow LED on a motor Start Button lights up, that Start button can be pressed to Start that Motor and the Green LED on that Start Button will light up and so forth.

It is also possible to alter the schematic so that each and every Motor Automatically starts up in the correct sequence instead of Manually starting each Motor.

TIME TAKEN FOR EACH INDIVIDUAL MOTOR TO REACH FULL SPEED (This must first be physically determined in practice):

When Motor M1 is started it draws Maximum Current from the electricity supply until it reached full speed and the current drops and settles and therefore it must first reach full speed (FS) before the next Motor M2 can be started and when Motor M2 has started is must also first reach full speed (FS) before Motor M3 can be started up and so forth. The individual starting of the Motors as described above results in a saving on the electrical cost in the Maximum Demand from the Electricity Supply Commision. Each individual Motors' Time it takes in Seconds to reach Full Speed (FS) can be entered in the spaces provided. The Motor Full Speed (FS) Delays in conjunction with the latches regulate this Full Speed (FS) Time Sequence.
