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
