System componentsDistributed I/OSIMATIC ET 200X8■ Overview• Distributed I/O system with IP65/67 degree of protection forcabinet-free use close to the machine• Modular design for adaptation to the automation task in hand• Input/Output Modules, motor starters, Pneumatic Modulesand modules for signal pre-processing (CPU)• Can also be used for time-critical tasks• Separate auxiliary supply for easy implementation of loadgroups• DESINA-compliant Modules■ Application■ Further informationSIMATIC ET 200X is a distributed I/O system with IP65/67 degreeof protection.For further information and ordering data see Catalog IK PI andthe Interactive Catalog under "Automation Systems/SIMATICDue to its high degree of protection and ruggedness, it is Industrial Automation Systems/Distributed I/O".particularly suitable for use close to the machine.The modular design and high degree of protection, the plug-inconnections, and the integration of pneumatic and drive componentspermit fast and optimal adaptation to the technologicalfunction units of a machine.Even if requirements change frequently, equipment setup timescan be reduced significantly by replacing or combining differentBasic Modules and Expansion Modules.The transmission rate of up to 12 Mbit/s on PROFIBUS DP makesthe SIMATIC ET 200X also perfectly suited for time-critical applications.By feeding in separate auxiliary voltages (load supply) for thePower Module, individual modules or module groups can beswitched off selectively.Connection to PROFIBUS DPOn PROFIBUS DP, the ET 200X occupies only a single nodeaddress on the bus that is set on the Basic Module. A separateI/O address can be assigned to each Basic Module and ExpansionModule.For the Basic Module with PLC functionality, the addresses forthe Expansion Modules are already set by the slot.The ET 200X complies with EN 50170 for PROFIBUS DP andcan be operated with all standardized masters. The 12 Mbit/stransmission speed also permits fast machine functions to beimplemented.■ DesignThe ET 200X distributed I/O system consists of:• One Basic Module each, with either- Digital inputs- Digital outputs- PLC functionality- ECOFAST-compliant- DESINA-compliant with parameterizable inputs and outputs• Max. 7 Expansion ModulesThe following Expansion Modules are available:• Digital inputs/outputs• Digital inputs/outputs in acc. with DESINA• Analog inputs/outputs• Modules with and without channel diagnostics• Moby Ident System• Pneumatic Module with integrated valves• Pneumatic interface for mounting a CPV valve assembly byFESTO; up to 6 interfaces per ET 200X station• Motor starter (electromechanical or electrical) for controllingany three-phase load (up to 5.5 kW (7.4 HP) at 400 V AC); upto 6 motor starters per ET 200X station• SITOP power supply (24 V DC optional)The Expansion Modules are arranged side-by-side by means ofintegrated plug-in connectors. All the necessary signal leadsand auxiliary voltages for inputs and outputs are looped throughin this arrangement. The modules can be replaced during servicing,without the entire station having to be dismantled.8/22 Siemens PM 10 · 2005
