Siemens S7-300 Simatic S7 300 Plc

The S7-300 is the individual solution for fast process and automation tasks that contain additional data processing tasks. It is high-performance, fast, versatile and future-proof. For engineering either STEP 7 V5.6/STEP 7 Professional 2017 or STEP 7 Professional in the TIA Portal can be used.
The SIMATIC S7-300 is connected to the PROFIBUS DP bus system via a communications module or via the CPUs with integral PROFIBUS DP interfaces. The CPUs with PROFIBUS DP master/slave interface enable distributed automation configurations with high speed and simple handling.
The distributed I/O via PROFIBUS DP is treated just like a centralized I/O from the user's perspective (same configuring, addressing and programming).
The following can be connected as masters:
SIMATIC S7-300 (via CPUs with PROFIBUS DP interface or PROFIBUS DP CPs),SIMATIC S7-400 (via CPUs with PROFIBUS DP interface or PROFIBUS DP CPs),SIMATIC C7 (via C7 with PROFIBUS DP interface or PROFIBUS DP CPs),SIMATIC S5-115U/H, S5-135U and S5-155U/H with IM 308,SIMATIC 505,
For performance reasons, no more than 2 masters must be connected on one line.
