Siemens PLC
General Description
This ROS2 module contains the required packages for interfacing with Siemens PLCs through the Snap7 protocol.
The module launches a ROS2 node that allows reading from a Siemens PLC database and writing into it through ROS2 services.
The Snap7 protocol is based on the Siemens S7 communication standard.

Description
Snap7 is an open-source software library that provides an interface for communication with Siemens S7 series PLCs. It enables users to access and interact with PLCs over industrial networks, allowing for both reading from and writing to various types of memory within the PLC.
Purpose in AI-PRISM
The driver is required to establish the communication among the ROS2 framework and physical Siemens PLCs that can control a robotic system.
