▶ C'mon over to https://realpars.com/ where you can learn PLC programming faster and easier than you ever thought possible! ============================= ▶ Check out the full blog post over at https://realpars.com/s7-300-versus-s7-1500/ ============================= Today you will be learning about the differences between the Siemens S7-300 and S7-1500 Advanced series PLCs. For both systems, a wide range of modules can be used according to the task at hand and a cost-effective stock of spare parts are readily available. Released in 2012, the SIMATIC S7-1500 is the successor of the longstanding S7-300 PLC. Although they are interchangeable in many situations, the S7-1500 generation integrates the latest and future-proof technologies into an automation system with enhanced system features over the S7-300. With the engineering system TIA Portal, the common engineering platform for all SIMATIC controllers, the SIMATIC S7-1500 is designed for fast market changes, constantly shorter product life cycles, and increasing cost pressures. Both the S7-300 and S7-1500 PLCs are similar in shape and size and are built around a modular, expandable design. CPUs, I/O modules and communication modules may be added as needed to a standard backplane that can be sized to fit your specific project. Up to 32 expansion modules can be installed with both systems, requiring only a DIN rail mount and backplane. The S7-1500 has a standard built-in display and keypad that allows for basic configuration and diagnostics without the need for an external screen. Both the S7-300 and S7-1500 series PLCs have many different configuration options that allow the optimal CPU to be selected depending on the application. Both platforms provide several CPU categories including: - Standard (for typical applications) - Compact (for applications where space and cost is a concern) - Fail-Safe (for fail-safe applications) The S7-1500 significantly increases performance over the S7-300 with a faster backplane bus, standard PROFINET interface, and shorter reaction times. As a result, the updated PROFINET interface provides greater reproducibility and precision in the microsecond timeframe. When programming for slower processes this may not make a noticeable difference in the real world, however, it can be very useful in high-speed applications such as assembly lines. Two Profinet ports come standard on every S7-1500 CPU although you may select additional ports and communication protocols when ordering. As an added bonus, you are able to configure these ports as a bridge which acts as a mini switch. This can be very convenient when linking devices and interfacing with the PLC in the field. With S7-300s, the desired number of ports and appropriate communication protocol must be chosen up-front. Prices between the S7-300 and S7-1500 are very similar between like models. If cost is a major concern, the S7-1500 compact version provides up to 70% cost savings, as well as 25% space savings compared to the standard CPUs, although some features are limited. There are several main factors to consider when selecting a PLC for your project. These factors are: - Application size, - Available space, - Communications protocols, - Processing performance. By using the Siemens website, you can select the appropriate PLC for your specific application. Here is the link to the PLC selection tool of Siemens: https://sie.ag/2GGMrkm In conclusion, both the S7-300 and S7-1500 PLCs are capable and proven systems, providing modular, cost-effective, and application-specific solutions to fit your needs. In the future, Siemens will slowly begin to phase out the S7-300 in favor of the S7-1500. Eventually, the S7-300s will no longer be supported, although that is still many years away. As of now the added benefits of the S7-1500 offered at a price point similar to the S7-300 make it a no-brainer to go with the updated PLC on your next project. ============================= Check out this link where you can select the right SIMATIC Controller for your application: https://sie.ag/2GGMrkm ============================= Missed our most recent videos?
