What is AS-i?
 A simple network for actuators and sensors
 Connects input / output devices to a PLC or PC
 Connects I/O devices to a two-wire flat cable
 Eliminates multiple terminations
 Easily replaces point-to-point wiring systems
 A complete networking solution

Point-to-Point Wiring vs. AS-i Networking
Point-to-Point Wiring
 Large wire bundles take up valuable space
 Installation time is considerable
 Troubleshooting is complex
Actuator Sensor-interface Networking
 Completely eliminates wire bundles
 Plug-and-play wiring supports all topologies
 Eliminates junction boxes and reduces the size of the control cabinet
Why Choose AS-i…
 A simple 2-wire flat cable
 Extremely fast system
 Insulation displacement
 Flexible topology
 Cost effective
 Best fit
 Modular system
An Overview of AS-i System Components
Two methods to connect AS-i to your existing control platform:
Method 1: Backplane Master Connection
 Fits in a standard card slot in a plc rack
 Plugs into backplane
 Replaces traditional I/O cards
 I/Os are mapped directly to I/O tables
 Programmed via the standard plc software

Method 2: Fieldbus Gateway Connection
 Connects to higher-level fieldbus systems
 Gateway becomes a single node on the fieldbus network
 Reduces the price per point for connecting sensors and actuators

After selecting connection method, choose an AS-i Power Supply
 An integral and necessary part of an AS-i system
 Provides power to all input devices and modules
 Couples the master data and 24 VDC power for transmission over the yellow flat cable
Field Input and Output Modules
Connects the AS-i master and periphery equipment Compact Modules
 Designed for harsh environments
 Rated IP67 for washdown environments
 M12 connectors for simple plug-and-play wiring Classic modules
 DIN rail mountable
 For areas with limited mounting space
 Rated IP67
 Equipment such as pushbuttons and motor starters can be connected to cabinet modules Cabinet Modules
 Rated IP20
 I/O modules may be daisy-chained together inside the enclosure
 DIN rail mounting

Intelligent System Solutions
Pneumatic Modules
 The airbox is a single AS-i node with up to four inputs and two integrated pneumatic outputs
 Stainless steel options for heavy washdown environments
 Ideal solution for distributed valve applications
Quarter-Turn Valve Feedback
 One cable can connect 31 quarter-turn valve feedback devices and 31 solenoid valves
 IND sensor and integrated output for a solenoid valve are networked with AS-i

The AS-i Networking System Complements Existing Bus Systems
 Dramatic cost savings for actuators and sensors
 Reduced engineering design time
 Eliminates trunk and drop line calculations
 Communication is transparent
 No terminating resistors
 No technical descriptive data files
• On Devicenet: EDS files
• On Profibus: GDS files
Benefits to Equipment Builders
 Reduces engineering design time
 Reduces BOM costs
 Easy commissioning for new machines
 Easy troubleshooting
 No additional software
Benefits for End-Users
Reduced maintenance costs
Easy troubleshooting
Easy expansion of existing systems in-house
