Issue:
Looking for an example on how to script an IF/ELSE statement in Blockly script in EcoStruxure Operator Terminal Expert

Resolution:
Take for example that we need to script the following block of code in Blockly script in EcoStruxure Operator Terminal Expert:
/**********************************************/
if((Var1==1) || (Var2==2) || (Var3==3))
{
Var4 = 1
}
else
{ Var4 = 0
}
/*********************************************/
We can make use of the following items in EcoStruxure Operator Terminal's Blockly script to establish the same multi-conditon IF/ELSE statement:
1) First we start with an Orange Trigger Block. For our example, I have chosen the Periodic - When - Do block. This will run every 100 ms.
2) The next block is the Purple If/Do/Else Block.
3) For the Logical "OR" of the 3 conditions, we need to snap two Blue Logicial Conditon Blocks together. If you had more conditions, you would use more of the same blocks.
4) Going deeper into the Logical Condition Blocks, we need to establish our comparison blocks. For this, we will three Blue Comparison Blocks. Note that these blocks need the blue Variable and Constant blocks as well. The Variable block is used to define the HMI variable and the Constant block is used to define the value to compare the HMI variable to.
5) Finally, we need to make our Do/Else operations. For these, we will use the Bronze Value Change blocks. Again, this block will need the blue Variable and Constant blocks as well. Remember to set the appropriate value to set Var4 to for the Do and Else conditions.
