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.
S The CPU executes the program and stores the data for controlling the automation task or
process.
S 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.
S 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:
S 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.
S Program development station (PDS 210).
S PC/PPI communications cable.
S 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.
