Note: In programming any point that uses multiple Flexput circuits are always referred to as the lowest Flexput
circuit number used. For example, Figure 4-39 uses Flexput circuits 1, 2, 3 together and 4, 5, 6 together.
In programming (1, 2, 3) would be referred to as point 1, and (4, 5, 6) would be referred to as point 4.
