open, a resistance check of the device with a digital multi-meter will give a reading of OL. If the device is normally closed, a resistance check will give a reading of 0.0. The normally open and normally closed state of the devices is not labeled on the ladder drawing. Rather, the reader must recognize the symbol.

Sep 03, 20171. Easier to read. First of all it makes ladder logic easier to read because it is natural for the eye to go from the left to right and then down to the next line. Just like when you are reading. Of course this applies only to people living in countries where the reading is done from left to right. 2. Drawn

Chapter 2: Basic Ladder Logic Programming
Ladder Logic Evaluation. For most PLC's, the ladder scan starts at the top of the ladder and proceeds to the bottom of the ladder, examining each rung from left to right. Once a rung is examined, it is not examined again until the next scan. The rungs are not examined in reverse order.

LADDER LOGIC "Ladder" diagrams Ladder diagrams are specialized schematics commonly used to document industrial control logic systems. They are called "ladder" diagrams because they resemble a ladder, with two vertical rails (supply power) and as many "rungs" (horizontal lines) as there are control circuits to represent.

NomenclatureOperationExampleEffectsSafetyThe L1 and L2 designations refer to the two poles of a 120 VAC supply unless otherwise noted. L1 is the hot conductor, and L2 is the grounded (neutral) conductor. These designations have nothing to do with inductors, just to make things confusing. The actual transformer or generator supplying power to this circuit is omitted for simplicity. In reality, the circuit looks something like this:See more on allaboutcircuits

How Do You Read an Electrical Ladder Diagram? - Reference
Quick Answer. To read an electrical ladder diagram, first identify the two rails that signify the supply power, and then locate the rungs that portray all of the control circuits connected to the power source. The L1 designation typically refers to the hot conductor on the 120-volt AC supply, and the L2 designation typically refers to the neutral,..People also askWhat is a ladder logic?What is a ladder logic?Ladder logic is a graphical programming languagewhich means that instead of text,the programming is done by combining different graphic elements. These graphic elements are called symbols. It is in between these two lines your ladder logic goes.
