System summary

System 300S | System descriptionSystem SLIOPerformance and ApplicationThe system 300S is designed for centralized and decentralized automationtasks. The integrated SPEED7 ASIC system 300S is among the world's fastestautomation systems. A wide range of CPU options makes the system universallydeployable. The selection ranges from C-class CPUs with integrated I/Operipherals for smaller applications up to CPU versions with built-in Ethernet,fi eldbus master interfaces, and High-Speed-Bus.The CPU versions with integrated SPEED-Bus have been especially developedfor automation tasks with very high demands on performance. Furthermorespecial high-speed modules for communication and for digital as well as analogsignal processing are available.System 100VSystem 200VProgrammingSystem 300S is programmed with WinPLC7 or with Siemens STEP7 in LAD,FBD and STL.MemoryThe CPUs in system 300S have the work and load memory already integrated.Depending on the CPU variant different work memory are available for the user.The work and load memory can be adapted to the needs of memory card byplugging in an MCC memory expansion card. To back up program and datastandard MMC cards are also supported.FunctionsFor the connection of sensors and actuators, a variety of signal modules areavailable for recording digital and analog signals into and out of the process isavailable - also as high-speed modules for SPEED-Bus.Measurements and the control of pressures, temperatures, fl ow rates and levelsare realized at the highest level with the measurement and control modules.System 500SSystem 300SHMICommunicationAn Ethernet programming interface is integrated on all CPUs in system 300S.Ethernet communication processors link system 300S horizontally and verticallyinto network structures. Therefore, all relevant data are made available to theconnected host systems.System 300S offers fi eldbus master and slave modules with different fi eldbusprotocols and can act as a master controller or as a subordinate fi eldbus slaveunit.Multi-master applications with very high performance of communication can beimplemented via the fi eldbus master module for SPEED-Bus.SoftwareAccessoriesAppendix43
