Welcome to another course in the STEP 2000 series, Siemens Technical Education Program, designed to prepare our distributors to sell Siemens Energy & Automation products more effectively. This course covers Basics of PLCs and related products.

Upon completion of Basics of PLCs you should be able to:

• Identify the major components of a PLC and describe their functions
• Convert numbers from decimal to binary, BCD, and hexadecimal
• Identify typical discrete and analog inputs and outputs
• Read a basic ladder logic diagram and statement list
• Identify operational differences between different S7-200 models
• Identify the proper manual to refer to for programming or installation of an S7-200 PLC
• Connect a simple discrete input and output to an S7-200
• Select the proper expansion module for analog inputs and outputs
• Describe the operation of timers and counters

PLCs consist of input modules or points, a Central Processing Unit (CPU), and output modules or points. An input accepts a variety of digital or analog signals from various field devices (sensors) and converts them into a logic signal that can be used by the CPU. The CPU makes decisions and executes control instructions based on program instructions in memory. Output modules convert control instructions from the CPU into a digital or analog signal that can be used to control various field devices (actuators). A programming device is used to input the desired instructions. These instructions determine what the PLC will do for a specific input. An operator interface device allows process information to be displayed and new control parameters to be entered.
