If Block
The If block represents a control flow operation. It is used when a program is needed to branch out outcomes or further actions dependent on mutually exclusive conditions.
The block can be found in the Block Library under the Control Flow section.
Overview
The If block contains a condition port. This allows it to act on a link.
The main particularity of this block is that it has one inflow gate and 3 outflow gates
The inflow gate can be linked to the Start block, or to another block that has an outflow gate providing input to the If block.
The outflow gates will be linked to each possible output
then - will follow a course if the condition is met
else- will follow a course if the condition is not met
next - (optional)will go to next action regardless of the then/else outcome
If block Example:
The program can be interpreted as thus: If the temp is higher than 95 degrees, then turn the chiller on else do not turn it on. Next, start someMacro.
