SIEMENS SIMATIC S7-200 CPU
The S7-200 CPU combines a central processing unit (CPU), power supply, and discrete I/O points into a compact, stand-alone device.
The CPU executes the program and stores the data for controlling the automation task or process.
Additional I/O points can be added to the CPU with expansion modules up to the physical size limits listed
The power supply provides electrical power for the base unit and for any expansion module that is connected.
The inputs and outputs are the system control points: the inputs monitor the signals from the field devices (such as sensors and switches), and the outputs control pumps, motors, or other devices in your process.
The communications port allows you to connect the CPU to a programming device or to other devices.
Status lights provide visual information about the CPU mode (RUN or STOP), the current state of the local I/O, and whether a system fault has been detected.
Some CPUs provide a real-time clock as a built-in feature, while other CPUs require the real-time clock cartridge.
A plug-in serial EEPROM cartridge provides a means to store CPU programs and transfer programs from one CPU to another.
A plug-in battery cartridge provides extended retention of data memory in RAM.
The S7-200 has been proven worldwide in applications covering all sectors as a result of its wide range of exceptional features:

SIMATIC S7-200 l:For service, networking, remote control and more: Communication at every level
The communications possibilities of the Micro PLC SIMATIC S7-200 are unique. The built-in RS 485 interfaces can operate at data transmission rates up to 187.5 kbit/s functioning as follows: • As a system bus with a maximum of 126 stations. In this capacity, it is possible to network programming devices, SIMATIC HMI products and SIMATIC CPUs without a problem. The integrated PPI protocol is used for pure S7-200 networks supporting multiple masters from a single port. In a network consisting of other Siemens components (SIMATIC S7-300/400 and SIMATIC HMI, etc.), the S7-200 CPUs are integrated as MPI slaves. • In Freeport mode (up to max. 115.2 kbaud) with user-specific protocols (e.g. ASCII protocol). This means the SIMATIC S7-200 is open for any connected device; for example, it enables connection of a modem, barcode scanner, PC, non-Siemens PLC and much 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 the package also enables connection to a Modbus RTU network as a Master or a Slave.
