Materials And Tools Required - Siemens SIMATIC S7-300 Getting Started

Introduction
This guide takes you through 6 commissioning steps to set up a functioning application by
running through a concrete example. In this way you will get to know the basic hardware and
software functions of your S7-300.
You should expect to spend approximately 1.5 to 2 hours on this example, depending on the
level of your experience.
Prerequisites
The following prerequisites must be fulfilled:
You must be familiar with the fundamentals of electronic/electrical engineering and have
experience of working with computers and Microsoft
The reference potential must be grounded. That means that the bridge between chassis
ground and functional ground must be installed (which is how the CPU is shipped).
Warning
!
The S7-300 is used as a component in installations and systems that require you to comply with
specific rules and regulations that vary depending on the application. Please note the relevant
safety and accident-prevention regulations, such as IEC 204 (emergency stop systems).
Non-compliance with these regulations can result in serious injury and damage to both machinery
and equipment.
