Introduction

As well as the entry the connection table, you can also modify specific connection parameters that were entered as defaults during the New connection dialog.

Opening the Dialog

To call the dialog for special connection properties, follow the steps outlined below:

1.Select the required connection in the connection table.

2.Select the menu option Edit " Object Properties

Result: The “Properties ISO-on-TCP Connection” dialog appears.

Tabs

The following tabs are available for ISO-on-TCP connections:

SGeneral

Displays the parameters of the connection and the local name of the ISO-on-TCP connection.

SAddresses

Displays the local and remote address information.

SOptions

Here, you can decide whether or not you want to use the connection for one of the access types FETCH or WRITE.

SOverview

This is an overview of all the configured ISO-on-TCP connections of the selected S7 station with their parameters and the status of the connection.

SStatus Information

This tab displays the current status information for the connection (valid at the time the dialog is opened). This information corresponds to that displayed by NCM diagnostics.

S7 specifications

The Siemens S7 series represents a cornerstone in the realm of programmable logic controllers (PLCs), developed by Siemens, a leading company in industrial automation. Widely used across various industries, the S7 series offers robust solutions for controlling machinery and processes, thanks to its reliable performance, flexibility, and scalable architecture.

One of the key features of Siemens S7 PLCs is the modularity of their design. Each system can be configured to meet specific application requirements due to the ability to mix various input/output modules, CPUs, and communication processors. This modular approach allows for the customization of systems to suit diverse automation tasks, providing end users with the adaptability required for modern manufacturing environments.

The S7 series encompasses several models, including the S7-1200, S7-300, and S7-1500. The S7-1200 is particularly suited for small to medium-sized applications, offering a compact design and integrated communication interfaces. In contrast, the S7-300 is designed for more extensive and complex control systems, making it ideal for large-scale industrial applications. The S7-1500 stands out with its advanced performance metrics, rich feature set, and high-speed processing capabilities, making it perfect for demanding applications that require real-time control and extensive data handling.

Siemens also emphasizes the importance of communication technologies within the S7 series. With options such as PROFINET, PROFIBUS, and EtherNet/IP, the S7 PLCs can seamlessly integrate into existing automation infrastructures, ensuring smooth data exchange between devices. The incorporation of web-based technologies and cloud connectivity further enables remote monitoring and control of systems, enhancing operational efficiency.

Another notable characteristic of Siemens S7 PLCs is the use of TIA Portal (Totally Integrated Automation Portal), an innovative software platform that simplifies the engineering process. TIA Portal allows users to program, configure, and diagnose their automation devices in a single environment, reducing setup times and improving productivity.

In conclusion, the Siemens S7 series stands out due to its modular design, range of models suitable for various applications, advanced communication technologies, and user-friendly programming software. This combination of features and characteristics makes S7 PLCs a preferred choice for industries seeking reliable and efficient automation solutions. As industrial demands continue to evolve, Siemens S7 PLCs remain at the forefront, adapting to technological advancements and setting benchmarks in the automation field.
