5 - PLC Memory & I/O
Configuration
Overview
This chapter shows you how to set up and configure your Siemens family
PLC. You must configure your PLC before you can create a ladder logic
program. Configuration is part of the program; it performs the important
function of relating the hardware components to the logic components.
The setup and configuration process is completed in three steps in
recommended order:
1. PLC Type Setup
• PLC Type
• Memory Size
2. PLC Memory Configuration
• Ladder
• Variable
• Constant
• Special
• User Sub
• Timer/Counter
• Drums
• Shift Register
• Table Move
• One Shots
3. I/O Configuration
PLC Type Setup, available in offline mode only, is how you tell 505
SoftShop what Siemens processor you are creating a logic program for.
PLC Memory Configuration and I/O Configuration allow you to
configure your PLC. These are available in online and offline mode.
