What is the difference between SIMATIC S7-300 and S7-1500 PLCS?
Overview
SIMATIC S7-1500, released in 2012, is a follow-up product of long-term S7-300 PLC.
Although the S7-1500 series can be interchanged in many cases, they integrate the latest and future technologies into the automation system and enhance the system function through S7-300.
Through the engineering system TIA Portal (general engineering platform for all SIMATIC controllers), S7-1500 is designed for rapid market change, continuous shortening of product life cycle and increasing cost pressures.
