Sub Block

The Sub Block allows the user to subtract a variable's value from another in order to use the result

The Sub Block can be found in the B-Line app, after creating a new program

Properties

The only properties that the sub block has are the two input fields: A and B, where the user must choose the variables (parameters)

How to use

The user must go to bLine Logic

In there he creates a program (or edits one) depending on his need (more information here ). 

In the Blocks menu the user can find all the blocks that he can use

Search for the sub bock in the right menu that opens 

Then drags the block over a main block like SET or IF

From there, the user just chooses the variables (which he can see how to add them, in here)

Example

The above screenshot represents a very basic setup on how to use and apply the and block.

We set up the value of deltaT as a subtraction of cTRT and cTST, then if the value of the subtraction is greater or equal to 10 we turn the Alarm On, if not the Alarm is set to Off

At the end there is an Alarm routine, you ca find more about it here
