The new CPU enables users to equip their installations with PROFINET while retaining the S300 design. The CPU can contact up to 128 PROFINET devices and features a PG/OP Ethernet interface for programming and for communication with the panels as standard. A PtP interface with protocols such as ASCII, STX/ETX, 3964, USS master and Modbus master is also available, along with MPI. The configuration and programming can be performed via the SIMATIC manager and the TIA Portal from Siemens, and in the near future, with the new engineering tool SPEED7 Studio.
