(in order to prevent overloading of the communication channel to the plc!)

ChessMaster Posts: 84 Rating: (1)	Thank you for the replay but actually i did not get my answer . I want to see changes online in the filed when i pressing the slider but in this why data has been writen to I/O filed when you release the left mouse on the slider. And there is another point : I need when operator hold left mouse key on the slider for a while (For example1 sec.), then increase of Tag will be occured. Also i need to determain time step of automatical increase or decrease and its step.

But for the increase to still happen while the user is pressing the button, you could copy the script you wrote in the mouse action to the "Object Change" event, within "Miscellaneous". Since when the user keeps pressing the slider the little bar tends to change position, the action will be triggered. But you'll need to work on how to make sure the interval is 1s... Check this thread, which mentions the kernell sleep function. Best regards, Danielle

I added a rectangle and put a script on a 1 second cycle under the line color attribute. Then based on what color the backround is it will either add or subtract. I then put an actionon the press left and release left to change the color of the rectangle. The rectangle is not displayed.I used an internal tag ( Float ) called Val1 Regards Shane Attachment Slider.zip (130 Downloads)

ChessMaster Posts: 84 Rating: (1)	Thank you CromptonS But in your sample we can only changeing Tag value by holding down the mouse key. I want to make difference when operator holding down the key and when he click on it once. I want when operator hold down the mouse key on UP botton for 1 sec. increasing action take place. and when he/she click once on UP botton, only increase once with different step. Could you help me with witch function i can findout how long operator holding down the mouse key on the specific botton? Best Regards

Danielle Posts: 1275 Rating: (123)	Hi, Did you check my previous post? The "object change" property would help with getting the action to work if the user kept pressing the button. But you'll have to create the 1s interval, and you'll also need to test this, to check if when the user presses the button just once, the increase will only happen once, or if the "object change" could mess it up a little (pressing the button once would get the object to change)... Best regards, Danielle

Danielle Posts: 1275 Rating: (123)	Hi, Is this bar the same one from the other thread? With the slider object you can accomplish this... but if you want to use it with a bargraph, which is what you'd need in the other thread, you'd need buttons to increase or decrease the value... The slider object already has buttons, but the bargraph doesn't... The catch is (and I can't test this right now) how to continue increasing every second if the user keeps pressing the button. The "Object Change" from the slider object does this, but I don't think the one from the button will, since the button itself isn't changing... How badly do you need this to work exactly as you described, and how many bargraphs like this would you need? I'm asking 'cause if it's only one, then a veeeeery ugly workaround would be setting an internal tag when the user clicks the button and using a global script to increase the tag whenever this internal tag was set. The internal tag would be reset when the user released the button, and the script would run each second... but once again - I think that's veeeeeeery ugly... Maybe someone else has a good idea for this... Best regards, Danielle

This is just to give you an idea of how to go about setting it up yourself. Probably better ways to do it. For your time calculation you could maybe take the initial value and write it to an internal tag when you press the button ( on the press left event ) and then read the value when you release the button ( release left event ) and subtract the two. You can thendivide the difference by the increment amount you set (0.01) and that multiplied by your tme trigger ( 1 sec ) should give you your amount of seconds the buton was down for.Not exactly accurate but it does seem to work. Add3 tags to your project"Val1" , 'Val2" and "Time" Best Regards Shane Attachment Slider.zip (101 Downloads)
