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.

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 ...

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...

The Method and Process of Siemens PLC Hardware Configuration

The hardware configuration of Siemens PLC can usually adopt the following methods and processes: Determine control tasks and system requirements: Before hardware configuration, it is necessary to clarify the tasks and requirements of the control system, including the requirements for input and output points, control accuracy, speed, and safety. Select the PLC model and module: According to the control task and requirements, select the appropriate PLC model and module, including CPU, I/O module, communication module, power supply module, etc. Assemble the cabinet and install the modules: According to the selected PLC model and module, assemble the cabinet and install the modules, pay attention to the installation sequence, cable wiring, wiring method, etc. Connect the input and output devices: connect the input and output devices with the input and output modules of the PLC, you need to pay attention to the correctness, stability and safety of the wiring. Perform software configura...
