A more selective method

In this example we are going to look at how inspired use of different functions can

simplify programming, but first lets look at a straightforward method.

VSA 1

Trigger: - Function 1 ON

Reset: - Timer 1 Done

VSA 2

Trigger: - Function 2 ON

Reset: - Timer 1 Done

Timer 1

Trigger: - Function 3 ON

Reset: - Timer 1 Done

Dwell: - 100

Function 1

Condition 1: - Input 1 ON

Condition 2: - Function 4 ON

Operator: - AND

Function 2

Condition 1: - Input 2 ON

Condition 2: - Function 5 ON

Operator: - AND

Function 3

Condition 1: - VSA 1 Done

Condition 2: - VSA 2 Done

Operator: - OR

Function 4

Condition 1: - VSA 2 Active

Operator: - NOT

Function 5

Condition 1: - VSA 1 Active

Operator: - NOT

This routine is exactly like 7; however instead of using the All VSA off it selectively

to do what was done with 2 in the previous example. However, there is a way of doing

it with only two using a NOR function. Remember the NOR truth table
