The Evolution of Siemens PLCs
Released in 2012, the SIMATIC S7-1500 emerged as the successor to the renowned S7-300 PLC. While both systems are interchangeable in many scenarios, the S7-1500 generation embraces state-of-the-art technologies, transforming the automation landscape. With its engineering system TIA Portal, the S7-1500 is designed to adapt swiftly to market changes, shorter product life cycles, and escalating cost pressures.
Similarities and Differences
The S7-300 and S7-1500 PLCs boast a modular and expandable design, sharing a common shape and size. Both systems offer the flexibility to customize your project by adding CPUs, I/O modules, and communication modules to a standard backplane. With up to 32 expansion modules, the possibilities are endless.
However, the S7-1500 sets itself apart with its built-in display and keypad, eliminating the need for an external screen for basic configuration and diagnostics. Moreover, the S7-1500 enhances performance with a faster backplane bus, a standard PROFINET interface, and shorter reaction times. This makes it ideal for high-speed applications like assembly lines, where precision and reproducibility in the microsecond timeframe are paramount.
The Power of Profinet
In the realm of communication protocols, the S7-1500 takes the crown. With two standard PROFINET ports on every S7-1500 CPU, you have the flexibility to configure these ports as a bridge, acting as a mini switch. This feature simplifies device linking and facilitates seamless communication with the PLC in the field. On the other hand, the S7-300 requires upfront selection of the desired number of ports and appropriate communication protocols.
Making the Right Choice
Price-wise, the S7-300 and S7-1500 stand shoulder to shoulder, with comparable costs for similar models. However, the S7-1500 compact version offers up to 70% cost savings and 25% space savings compared to standard CPUs, making it an attractive option for budget-conscious projects.
When selecting a PLC for your project, consider factors such as application size, available space, communication protocols, and processing performance. The Siemens website provides a handy tool to help you find the perfect PLC for your specific application. In most cases, the S7-1500 can seamlessly replace the S7-300, offering additional benefits like a built-in display for easy configuration and plain-text diagnostic information for faster troubleshooting.
Embrace the Future
Siemens is gradually phasing out the S7-300 in favor of the S7-1500, which offers an array of added benefits at a similar price point. While the S7-300 will be supported for several more years, it’s evident that the S7-1500 is the future of PLCs. Why not embrace the cutting-edge technology and propel your next project to new heights?
