Jump Instruction in Siemens Tia Portal

 In this article, I will explain to you about the use of the JUMP instruction using Siemens TIA PORTAL

The jump instruction is used to skip part of the logic or rungs during the program run.

Now, why JUMP instruction? You may ask. The simple answer is to reduce scan time (one of the advantages).

To jump unnecessary logic which we don’t want to execute while program in run mode can reduce the amount of scan time.

Let’s dig deeper to understand JUMP instruction with the help of an example.

Jump Instruction in Siemens Tia Portal

Open TIA PORTAL. Enter into a programming environment.

I have added little program in the second network as you can see in the below window.


Now, I want to skip that second network. To do that I have added JUMP instruction in the first network.

In the third network, I added a label, which indicates the location of the jump.

To use JUMP instruction, you have to define it. You can define any name but always remember to use the same name as the label.

Here in our case, I have used the letter “D” in both JUMP and label instruction.

You can see in the below window, execution of the JUMP instruction.

When you turn ON input in the network 1, JUMP instruction will execute which then goes to the label and execute the logic. (in our case it goes to the rung where the label is used)

You can see that when JUMP instruction is active, the second network is disabled.

As you can see in the below window that if I try to turn ON the input in the second network, the output won’t get energized.

As soon as you switched off input in the first network, the second network will be activated again.

Ferrules and Cross Ferruling

 Ferrules are identification labels provided for every wire terminations in an instrument, equipment, or electrical/instrumentation control panels. These tube-shaped sleeves can be inserted easily on each individual wire in a multi-core cable. In earlier days fixed digits/letters are used as ferrules, but now Instrumentation engineers/technicians prints out desired ferrules by using a ferrule printing machine. Typical Ferrule The numbers/ letters on the ferrules will be given as per the approved electrical hook up or loop diagrams. This helps technicians to easily identify a particular loop/wiring from a series of terminal blocks and to troubleshoot the desired terminal connection. Separate numbers on the ferrules distinguish the positive and negative polarities of wires, thus ensure the polarity protection of the instrument. Cross Ferruling  As a wire is connected on its both ends, it is quite useful to use a cross reference method for wire identification. Unlike normal ferru...

What is a Torbar? – Averaging Pitot Tubes

 The Torbar is employed for flow measurement of liquids, gases, or steam in circular, square, or rectangular section ducts for large flow rates. The Torbar is an insertion type multi-port self-averaging primary sensor for flow measurement. Torbar TORBAR is a set of Pitot tubes mounted on a bar across the pipeline with no moving parts. An averaging Pitot tube is a technology, while TORBAR is a manufacturing brand name. There are several brands available in the market with VERABAR, ANNUBAR, etc. Averaging Pitot Tube Principle Purpose Averaging Pitot tube can be employed when the average velocity of the flow profile, rather than the velocity in a specific point in the cross-section is desired. Averaging Pitot Tubes Principle It measures the differential pressure between the static pressure tap and the tap of full pressure of a stream. Thus such magnitude of differential pressure is directly proportional to the square of the flow rate. Working The TORBAR is designed in such a way that ...

Dissolved Oxygen Analyzer Working Principle

 What is dissolved oxygen ? Dissolved oxygen refers to oxygen dissolved in water. Its concentration is expressed as the amount of oxygen per unit volume and the unit is mg/L. Biologically, oxygen is an essential element for respiration of underwater life and also acts as a chemical oxidizer. The solubility of oxygen in water is affected by water temperature, salinity, barometric pressure, etc. and decreases as water temperature rises. Measurement of dissolved oxygen by the membrane electrode method The membrane electrode method measures a diffusion current or reduction current generated by the concentration of dissolved oxygen or partial pressure of oxygen to obtain the concentration of dissolved oxygen. This method is not affected by the pH value of water being measured, oxidation and reduction substances, color, turbidity, etc. and the measurement method offers good reproducibility. When a sensor is inserted into water, an air layer forms on the membrane (Teflon membrane). The ox...
