In today's world, data is becoming ncreasingly important as it is generated generated, stored and processed everywhere. Be it for customer and supplier contact with customers and suppliers, in production or administrative matters - data is the most important asset.

"Structured data all the way to the cloud"
To be able to work with extensive S7 machine data, we recommend an SQL database.
"Structured data all the way to the cloud"
The open, Ethernet-based communication standard OPC UA (Open Platform Communications Unified Architecture) offers the best conditions for digitalisation. Ideal for communication between machines and vertically into the cloud. For real-time communication at field level, Siemens combines OPC UA with PROFINET in a shared Industrial Ethernet network.
OPC UA with client/server communication is widely used in automation widespread in automation.
OPC UA with client/server communication is widely used in automation. widespread in automation. In this proven "one-to-one" communication mechanism, each OPC UA client receives a point-to-point access to the data of the OPC UA server via point-to-point communication. UA server: The OPC UA client sends a request to the OPC UA server and receives a response from it. and receives a response from it.
This enables reliable, secure and encrypted data encrypted data exchange with reduced bandwidth and without data data loss, even if the environment and network quality are not optimal and network quality are not optimal and are subject to interference.
Client/server communication is always based on TCP/IP.
To be able to work with extensive S7 machine data, we recommend an SQL database.
In order to be able to work with extensive S7 machine data, we recommend an SQL database. What exactly this is and how it works is explained in the next step. Then we will show you how you can enter a data record from your Siemens S7 PLC into a database table into a database table.
But first we would like to clarify the question of why you shoul use a database at all. You can simply store your manage your machine data in Excel tables and graphs, right? That's not wrong, but a database offers decisive advantages:
As you can see, managing your machine data in a database offers database offers decisive advantages. To summarise, the central centralised data management simplifies all processes. Data from a database are also easier to read and manage. If you are searching for certain data records, for example, this search can be completed in a database can be completed in less than a second.
However, if you save your data in Excel files, the search is often time-consuming and cumbersome. Excel is therefore suitable for small data volumes that are required by a single person. An SQL database is the next logical step if you want to store and manage larger amounts of data. Another plus point: Increased security of your data. Multi-user capability, the possibility for several people to work with the data at the same time work with the data at the same time make your production more professional and more efficient.
Databases are everywhere these days, even your Google searches are recorded in a structured database. With view of the increasing amount of data that we generate every day and have at our disposal every day, the importance of databases cannot be overlooked.
MySQL is recommended due to its longevity and popularity. It is perfect for getting started, which is why we will show you below in the article how you can write machine data from an S7 to an SQL database and vice versa.
Good data management is increasingly becoming a strategic competitive advantage for companies. Because today, data forms the foundation of all departments: Purchasing, production, sales, controlling. They all rely on up-to-date and readily available information. Find out more and contact us.
