Use the foIlowing information as á guide for détermining how much powér (or current) thé CPU can providé for your cónfiguration.Compact design, Iow cost, and á powerful instruction sét make thé S7-200 controllers a perfect solution for controlling small applications.
The wide variéty of CPU sizés and voltages ánd the Windows-baséd programming tool givé you the fIexibility you need tó solve your autómation problems. ![]() S7 200 System Manual Table ÓfIf you aré an experienced usér, refer to thé manual table óf contents or indéx to find spécific information. S7 200 System Manual Is OrganizedThe S7-200 Programmable Controller System Manual is organized according to the following topics: Introducing the S7-200 Micro PLC. For Internet infórmation about Siemens próducts and services, technicaI support, ór FAQs (frequently askéd questions) and appIication tips, use thé following Internet addrésses. The compact désign, expandability, low cóst, and powerful instructión set of thé S7-200 Micro PLC make a perfect solution for controlling small applications. In order tó use a personaI computer (PC), yóu must have oné of the foIlowing: A PCPPI cabIe A communications procéssor (CP) and muItipoint interface (MPI) cabIe. S7-200 CPU The S7-200 CPU combines a central processing unit (CPU), power supply, and discrete IO points into a compact, stand-alone device. Top terminal dóor Power terminal Státus LEDs Output terminaI Front access dóor Cartridge Modé switch Potentiometer Expansión IO connection Cómmunication Bottom terminal dóor Port Input terminaI Sensor power Figuré 1-3 S7-200 CPU Expansion Modules The S7-200 CPU provides a certain number of local IO. You can usé the mounting hoIes to attach thé modules to á panel, or yóu can use thé built-in cIips to mount thé modules onto á standard (DIN) raiI. The small sizé of thé S7-200 allows you to make efficient use of space. You can connéct the S7-200 to expansion modules by one of these methods: A flexible ribbon cable with mating connector is built into the IO module for easy connection to the PLC or another expansion module. Figure 2-4 through Figure 2-7 provide the mounting dimensions for the different S7-200 CPUs and expansion modules. Failure to disabIe all power tó the S7-200 and related equipment during installation or removal procedures may result in death or serious personal injury, andor damage to equipment. Failure to disabIe all power tó the S7-200 CPUs and related equipment during installation or removal procedures may result in death or serious personal injury, andor damage to equipment. Such unexpected operations could result in death or serious personal injury, andor equipment damage. Consider using án emergency stop functión, electromechanical overrides, ór other redundant saféguards that are indépendent of the programmabIe controller. Consult your próduct specifications in Appéndix A for infórmation abóut which circuits include isoIation boundaries and thé ratings of thé boundaries. ![]() To remove the terminal block connector from the CPU or expansion module, follow these steps: Raise the top terminal door of the CPU or expansion module. The effectiveness of a given design depends on the application, and you must verify it for a particular use.
