The title suggests a comprehensive guide aimed at explaining how to establish a connection between vNode, a software platform, and a Siemens PLC S7-1200 for the purpose of extracting data and monitoring various registers within the PLC.
The first step in this process involves creating a new module in vNode, specifically using the SiemensClient module. This module will allow us to establish communication with the Siemens PLC to exchange data.
Once we have created the module, we proceed to its configuration. Here, the main task is to establish an appropriate communication channel. In this channel, we will configure the necessary parameters for the connection, such as the IP address. number of Rack and Slot of the Siemens PLC we want to connect to. These details are essential to ensure a stable and effective connection.
It is crucial to emphasize that once we have made all the necessary configurations, it is important to save the configuration properly. This will ensure that the settings made are properly preserved and available for later use.
Last but not least, we come to the process of mapping Siemens addresses to tags within vNode. This step allows us to assign specific addresses from the PLC to tags within vNode, making it easier to read and write data between the two systems. By creating new tags in vNode and assigning them the corresponding Siemens addresses, we can easily access PLC data and use it in our applications or processes.
You can use this table to help map the data correctly within vNode. Additionally, please refer to our manuals available on our website for more detailed guidance.
