What rules should be followed when converting a schematic?

Question

Quizplus · Accepted Answer

The Answer is There are some basic rules that should be followed when making a conversion.
-Each line of logic must end with a coil.
-Any contact labeled the same number as a coil is controlled by that coil.
-Each relay can have an infinite number of contacts and they can be assigned as normally open or normally closed.
-Any coil assigned the same number as an output will control that output.
-Any contact assigned the same number as an input is controlled by that input.
The PLC assumes inputs to be low (no power applied) when the program is loaded into
-memory. When power is applied to an input, it will cause the contact assigned to that input to change state. A normally open contact will close and a normally closed contact will open.
-Any number of contacts can be assigned to the same input.
