What is Resources Tab in the Siemens PLC?

In this article, we will learn about the information you can get from the resources tab of the Siemens PLC.

Resources as the name indicate it contains all the information related to the PLC program.

Let’s take a software tour and find out where the resources tab is and what it contains.

Here, I will show you in the both TIA PORTAL and the Simatic manager.

Resources Tab in Siemens PLC

Let’s first open TIA PORTAL. Enter into the programming environment.

On the left side select the CPU and do right-click on it. From the list choose “call structure”.

The following window will appear. On the right side in the corner, you can see the “resources” tab.

Click on it.

As you can see in the below window in the resources tab you can have detailed information of the used and unused I/Os, CPU memory, and memory space consumed by programming and data blocks.

In the CPU memory, you can see the amount of the used and remaining memory. The same way you can access all the information about the programming and data blocks.

In the input and output section, you can see the information on the number of inputs and outputs you have configured for the project.

You can also see the used input and output section. This is a piece of really very helpful information to have as an automation engineer.

This can be helpful while implementing a new control system or installing a new machine.

To access the same information using Simatic manager first open it. Go to the programming environment.

However, in Simatic manager, it won’t have a specific tab to check resources but you can see memory space as shown in the below window.

Click on “module information”.

The following window will appear. Click on the memory section and you have information about memory space used by the program.

In this tab, you have access to lots of information about the PLC program.

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...
