For service, networking, remote control and more:Communication at every levelThe communications possibilities of theMicro PLC SIMATIC S7-200 are unique.The built-in RS 485 interfaces can operateat data transmission rates up to 187.5kbit/s functioning as follows: As a system bus with a maximum of126 stations. In this capacity, it ispossible to network programmingdevices, SIMATIC HMI products andSIMATIC CPUs without a problem. Theintegrated PPI protocol is used for pureS7-200 networks supporting multiplemasters from a single port. In a networkconsisting of other Siemens components(SIMATIC S7-300/400 and SIMATIC HMI,etc.), the S7-200 CPUs are integrated asMPI slaves. In Freeport mode (up to max. 115.2kbaud) with user-specific protocols(e.g. ASCII protocol).This means the SIMATIC S7-200 is openfor any connected device; for example,it enables connection of a modem, barcode scanner, PC, non-Siemens PLC andmuch more.By means of the USS protocol for drives,as many as 32 Siemens frequency converters can be controlled without additional hardware. The Modbus RTU Library included in thepackage also enables connection to aModbus RTU network as a Master or aSlave.6OPC Driver with PC AccessPC Access is the ideal basis for data exchange between S7-200 and a connectedPC – regardless of the communicationlink selected (PPI, modem, Ethernet/ITCP). As an OPC Server, PC Access offersyou the option of writing or readingS7-200 data with Microsoft Excel, or anyother OPC client application. As an OPCClient, it can be used for ProTool Pro,WinCC flexible RT, Win CC, etc. With capability up to 8 connections, the configuration, programming and monitoring canbe implemented from a central location,saving both time and money.The Internet Technology moduleCP 243-1 IT also offers you fast access bypermitting a simple universal connectionof the PLC to different computers bymeans of FTP, HTTP, JAVA, and e-mail.The Ethernet module CP 243-1 allows youto access S7-200 process data quicklyover Ethernet for archiving or furtherprocessing. The configuration supportfrom STEP 7-Micro/WIN ensures simplecommissioning and convenient diagnostic options.Modem communicationsThe S7-200 CPUs can be accessed nearly anywhere inthe world by modem via wired network or radio. Teleservice: the modem communication option isuseful for avoiding expensive service calls. Twomodems are all you need for remote use of thecomplete range of functions such as program transfer,status or control; the communications tools areintegrated as a standard feature. External modems canbe used as local modems. Telecontrol: you can call up messages and measuredvalues via modem as well as define new setpoints orcommands. In this case, one base station S7-200 cancontrol a nearly unlimited number of remote stations.The protocols for data transmission are freelyselectable, e.g. for text messages directly to a cellphone, error messages to a fax machine or ModbusRTU.Speedy PROFIBUS connectionAll CPUs from 222 upwards can be run via the EM 277communications module as a norm slave on aPROFIBUS DP network with a transmission rate of up to12 Mbit/s. This open feature of the S7-200 to higherlevel PROFIBUS DP control levels ensures you canintegrate individual machines into your production line.With the EM 277 expansion module, you can implementPROFIBUS capability of individual machines equippedwith S7-200.Powerful AS-Interface connectionThe CP 243-2 turns all CPUs from 222 upwards intopowerful masters on the AS-Interface network.According to the new AS-Interface specification V 2.1,you can connect up to 62 stations, making even analogsensors easy to integrate. With AS-Interface, you canconnect up to 248 DIs 186 DOs in the maximumconfiguration. The max. number of 62 stations caninclude up to 31 analog modules. The configuration ofthe slaves and reading/writing of data is supported bythe handy AS-Interface Wizard.

Great well-rounded technologyMemory cartridgeSmall and practicalSITOP smart – optimally matchedto SIMATIC S7-200SITOP smart is one of the narrowest DINrail mounted power supply units and exhibits an impressive overload behavior.Even high loads can be switched on without any problems. Nominal outputs ofcontinuous 120 percent position thepower supplies as the most reliable oftheir class. Numerous certifications simplify their universal and worldwide use,as well as their deployment under hazardous conditions.EEPROM memory modulesA small optional EEPROM memory module cansave you a lot of time and cost. It makes it veryeasy to copy, update or exchange your userprogram on the device. And if necessary, youcan use this module to send a program quicklyand inexpensively to your customers. You justshut off the power, plug in the module, turn itall back on – and the program is instantly updated. Whether project documentation, recipehandling or data logging – our memory modules are available with 64 KB or 256 KB.Battery moduleTo ensure no user data is lost, you canuse the optional battery module for longterm backups to extend backup time fromthe roughly 5 days of internal backup to,in general, a total of 200 days.For tough customers: SIPLUS extremeOperating under extreme conditions?No problem! If you have to operate yoursystem in an extended temperaturerange, require added condensation protection or demand other voltage ratings,then SIPLUS extreme is the solution foryou. It lets you adapt your CPUs to yourspecial requirements.Available optionsProject documentation Bitmap files, PDF files, DOC files Complete STEP 7-Micro/WIN projects canbe transferred to the memory card withS7-200 Explorer – giving you onsiteaccess to the current user data at alltimes even without STEP 7-Micro/WINRecipe handling Definition and download of the recipes,e.g. production data, machine parameters, etc. Better use of memory by occupying thedata memory in the CPU with only onerecipe: online updating and adaptationData logging Dynamic storage, e.g. of performance orstatistics data and fault or error messages Optionally with time stamp Log file transferable to PC via S7-200ExplorerReal-time clockWhether you need to count operatinghours, warm up rooms or attach a timestamp to messages: the integrated realtime clock on the S7-200 runs to theminute and to the day via the softwareaccording to your settings – even in leapyears. Including automatic daylight saving time switchover.Analog potentiometersWith the integrated analog potentiometers on the S7-200, you can optimize theprocess sequence almost “according tofeel” without a PC or HMI. They let youfine-tune the contents of data registries,time values, preassigned counter valuesor other parameters without meddlingwith the program. This is a practical way,for example, to change a welding time ordelay time quickly and directly.15
