The parts that typically go with a Siemens S7-1200 PLC can vary based on the specific application and the requirements of the automation system. However, here's a list of common components that are often used alongside an S7-1200 PLC to create a functional industrial automation setup:

• Power Supply Unit: Provides the necessary electrical power to the S7-1200 PLC and other connected devices.
• Input/Output Modules (I/O Modules): These modules allow the PLC to interface with sensors, switches, buttons, and other input devices, as well as control actuators, motors, solenoids, and other output devices.
• Communication Modules: These modules enable communication between the PLC and other devices, networks, or systems. This can include modules for Ethernet communication, serial communication, and other protocols.
• HMI (Human-Machine Interface) Display: A HMI display allows operators to interact with the PLC and the automation system. It can include touchscreens, buttons, indicators, and graphical interfaces.
• Programming Software: Software tools like Siemens' TIA Portal (Totally Integrated Automation Portal) are used to program, configure, and monitor the S7-1200 PLC.
• Communication Cables: Cables are necessary for connecting the PLC to other devices, such as a computer for programming or monitoring purposes.
• Sensors and Actuators: These are the devices that the PLC interacts with to control the physical processes. Sensors provide input data, while actuators execute commands based on the PLC's instructions.
• Terminal Blocks and Wiring: These are used to connect the PLC to the various input and output devices, as well as the power supply.
• Mounting Accessories: Components for securely mounting the PLC and modules onto a panel or other surfaces.
• Enclosures: Enclosures provide protection for the PLC and its components from environmental factors such as dust, moisture, and temperature variations.
• Power Distribution Components: Components like circuit breakers, fuses, and relays ensure safe power distribution and protection for the PLC and connected devices.
• Networking Hardware: If the PLC is part of a larger networked system, networking hardware such as switches and routers may be required.
• Backup and Data Storage Devices: Devices like SD cards or USB drives might be used to store backups of PLC programs and data.
