Specify the PLC model, either Model 300/400 or Model 1200, to ensure the appropriate communication methods and protocols are applied. Model 300/400: The S7-300 and S7-400 are traditional, modular PLCs known for their flexibility and use in more complex automation systems. They often utilize the PROFIBUS or PROFINET communication protocols, depending on the specific modules and configurations in use. Model 1200: The S7-1200 is part of Siemens' newer generation of PLCs. It's more compact and designed for small to medium automation tasks. It primarily uses PROFINET for communication. |
