The Simatic S7-300 is a controller for the lower to medium performance level of the company Siemens.
It was introduced as the successor to the Simatic S5 in 1995.
The range of applications of the SIMATIC S7-300 is widespread, especially in all kinds of machine.
The automation system is modular, consisting of:
Central processing unit (CPU):
For different performance ranges there are a number of CPUs, />
and CPUs with integrated PROFIBUS DP, PROFINET, and point-to-point interface.
Signal modules (SM) for digital and analog inputs and outputs.
Communication processors (CPs) for bus connection and point-to-point connections.
Function modules (FM) for high-speed counting, positioning(Controlled / regulated) and controlling.
For systems with increased safety requirements, the fail-safe SIMATIC S7-300F can be used.
For programming the software STEP 7 or the TIA Portal version 11 or higher is required.
Over the years, the S7-300 has been innovated constantly, so even though the basic design remained the same,
the performance always reflects the current state of technology.
At the SPS / IPC / Drives 2012 in Nuernberg the successor S7-1500 was presented.
However, the S7-300 will still perform its job for many years in numerous applications.
