Installing the S7-200 CPU 210
1.1

Product Overview

The CPU 210 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.
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.
Status lights provide visual information about the CPU mode (RUN) or whether a system
fault (SF) has been detected.

Equipment Requirements

As shown in Figure 1-2, you use the STEP 7-Micro/WIN programming software with a
program development station (the PDS 210) to create and to test your program. The final
program is then loaded onto a memory cartridge, which is then installed in the CPU 210. You
need the following equipment to create programs for the CPU 210:
Personal computer (PC) running the STEP 7-Micro/WIN programming software. Refer to
Chapter 2 for the requirements for installing the STEP 7-Micro/WIN software.
Program development station (PDS 210).
PC/PPI communications cable.
Memory cartridge for transferring the program to the CPU 210.
Refer to the data sheets in Appendix A for order numbers and other specifications of this
equipment.
