Steps to Designing a Successful System
Step 1: Review the Installation Guidelines
Always make safety your first priority in any system
application. Chapter 2 provides several guidelines that will
help provide a safer, more reliable system. This chapter also
includes wiring guidelines for the various system
components.
Step 2: Understand the CPU Setup Procedures
The CPU is the heart of your automation system and is
explained in Chapter 3. Make sure you take time to
understand the various features and setup requirements.
Step 3: Understand the I/O System
Configurations
It is important to understand how your local
I/O system can be configured. It is also
important to understand how the system
Power Budget is calculated. This can affect
your I/O placement and/or configuration
options. See Chapter 4 for more information.
Step 4: Determine the I/O Module Specifications and
Wiring Characteristics
There are many different I/O modules available with the DL205
system. Chapter 2 provides the specifications and wiring diagrams
for the discrete I/O modules.
NOTE: Analog and specialty modules have their own manuals and are not included in this manual.
Step 5: Understand the System Operation
Before you begin to enter a program, it is very helpful to
understand how the DL205 system processes information.
This involves not only program execution steps, but also
involves the various modes of operation and memory layout
characteristics. See Chapter 3 for more information.
