-==== Show Custom Message Box from PLC ====
+===== Show Custom Message Box from PLC =====
-In [[plc:plc_gas_cutting_implementation|previous article]] we showed how to implement oxyfuel gas cutting procedure. Preheat process in gas cutting can last 30-120 seconds. It is convenient to have on screen message that shows preheat progress. Let's add message box with preheat progress countdown for gas cutting.
+In order to create a custom popup window in myCNC software for an event like an emergency button press, a software PLC procedure can be added to the myCNC software for the user's specific needs and requirements. In order to do so, go to CNC Settings > PLC > Software PLC, then create a new popup window following the instructions below:
-Global variables 9100-9163 are reserved to show/hide enumerated Popup message box.
+. Press the **Create New** button in the Software PLC window
-Writing "1" to register (9100+N) will show Message Box #N on the main screen. Writing "0" will hide the Message Box.
+{{:plc:001-open-create-window.jpg}}
-Content for message box #0...#63 defined in cnc-variables.xml configuraton file by item **cnc-popup-message-0** ... **cnc-popup-message-15**
+. Name your new window and press the **Confirm** button
+{{:plc:002-custom-box-name.jpg}}
-<code xml>
+. Click **Save** and **Build All**
-<value name="cnc-popup-message-0"
+{{:plc:003-custom-box-save-build-all.jpg}}
-  header="Preheat Countdown" footer="sec" message="%d"
-  headerHeight="60" footerHeight="30" width="300" height="150"
-  fontSize="60" headerFontSize="30" footerFontSize="20"
-  timeout="5" dest="cnc-gvariable-99" K="0.001">0</value>
-</code>
-Message box contains 3 lines. Lines defined by attributes **header** (top line), **message** (middle line), **footer** (bottom line). Font size for each line defines by attributes **headerFontSize**, **fontSize** and **footerFontSize**
+At this point, the popup window's code must be edited to appear when a specific event occurs.
-Line height for each line defined by attributes **headerHeight**, **height** and **footerHeight**.
+. Copy and paste the following code into the window, then click **Save** and **Build All** again:
+<code>
+main()
-Attributes **width** and **height** define message box width and height in pixels.
+{
-Popup Messagebox will be automatically hidden if variable value was not changed longer than time defined in **timeout** attribute.
-Parameter value can be printed in Message Box. To print a value -
+do
-  * Message attribute should contain C-style contains format line (ie "%d", "%7.3f")
+{
-  * Attribute **dest** should define variable number
-  * Attribute **K** defines scale ratio.
-For example if
+if (portget(3)!=0) //Port 3 is used here. Use the actual port number for your particular setup
-  * message="%d"
+{
-  * dest="cnc-gvariable-99"
+ gvarset(9101,1);  //Brings up window 01. Windows 01 through 63 can be assigned to different tasks
-  * K="0.001"
+};
-Variable #99 value multiplied by K-ratio will be printed: if variable value is 95000, value **95** will be shown.
+}while(1);
-{{plc:mycnc-eco-popup-message-01.png}}
+};
+</code>
+. In order to edit the newly created window, we can open CNC Settings > Screen > Popup Messages, and then press **Create New**
+{{:plc:004-custom-box-save-popup-window-new.jpg}}
+. Fill in the information regarding your new popup window and press the **Save** button. The Hide Timeout field is in seconds.
+{{:plc:005-custom-box-popup-window-info.jpg}}
+At this point, whenever the selected port will send a message to a controller (for example, when a button is pressed), the software should bring up a popup window that will go away after the number of seconds specified in the Hide Timeout field.

-Source code to show Message Popup is
-<code c>
-  gvarset(9100,1);  //show the Message Box
-  portset(OUTPUT_OXY_HEAT_HI); //turn ON preheat Valve
-  timer=time_preheat;
-  break_heating=1;	//Set Heating variable.
-  //if the value will be clearen outside of PLC, abort Preheat procedure
-  do {
-    timer--;
-    if (portget(6)!=0)	//if start key is pressed - start piercing
-      {
-	timer=0;	//exit from heating
-      };
-    if (break_heating==0)   //if start key is pressed - start piercing
-      {
-	timer=0;	    //exit from heating
-      };
-    if ((timer&0xff)==0)
-      {
-	gvarset(99,timer); //update Countdown value every 256msec
-      };
-   }while(timer>0);        //Preheat loop
-  gvarset(9100,0);         //hide Message Box
