Purpose
The Event Action (EV) block tests the value or alarm condition of the previous block using IF-THEN-ELSE logic. Based upon the outcome of the test expression, the block can then either open or close a digital point or turn a block on or off scan.
Features
The Event Action block:
- Is a secondary block.
- Has undefined default values so that if a field is left blank, no action takes place.
- Tests up to two conditions consecutively.
