AS-i, The Simplest Automation Networking Solution Dated: 10/30/2008 What is AS-i? Actuator Sensor interface (AS-i) is a simple wire reduction system Easily replaces point to point wiring and complements existing higher level bus systems Reduces wiring and eliminates multiple termination points Connects inputs and outputs via a single two wire flat cable Easy to install and commission AS-i vs. Point-to-Point Wiring Point-To-Point Wiring Each bit of data needs its own wire. Power is run separately (more wires). Additional I/O points require additional PLC I/O cards. Additional PLC I/O cards may require the use of a larger PLC rack or multiple racks. Less Material & Labor Smaller PLC rack. Smaller enclosures. Less wire. Standardized patch cables. Potential to eliminate J-boxes. Simpler documentation. Less commissioning time. Simple Installation & Expansion One cable for many bits of data. One master replaces many PLC I/O cards = less wiring. Quick disconnect at modules vs. point-to-point terminations. I/O modules connect easily to the bus via insulation displacement connectors (IDC). Simple Installation & Expansion Modules connect easily to the bus via insulation displacement connections (IDC). mechanical coded flat cable Mechanically coded flat cable - AS-i and additional power supply Insulation displacement connectors - simple & safe - protection class up to IP67, - cables reseals up to IP65 piercing connectors AS-Interface electro-mechanics Easier Troubleshooting Less wire means less opportunity for error, less places to look for errors. Communication errors are captured by the master. Indicating lights on modules and masters communicate system and module status. Reducing overall machine cost AS-i can reduce up to 50% of the overall machine cost Wiring Labor Cost X Wire labeling Cost X Machine Assembly Labor Costs X Machine Testing Labor Cost X Machine Disassemble Cost X Shipping Cost X Customer Site Start up/ Commisioning Labor X Travel Cost X Time = Money AS-i Installation AS-i Installation Overview of AS-i system components AS-i Components AS-i Specifications 100 meters max. length per segment. With repeaters up to 300M Up to 62 node addresses per network 248 inputs and 248 outputs AS-i transmits only 4 data bits per message. Auto Address replacement Topology free network Single two wire unshielded cable carries input power and communication Max. of up to 10ms response time Control Integration Two methods to connect AS-i to your existing platform Method 1: Direct PLC connection Fits into standard card slot in a PLC rack Replaces traditional I/O cards I/O are mapped directly to I/O tables Programmed and configured through standard PLC software No 3rd party software needed Available for most PLC platforms Control Integration Two methods to connect AS-i to your existing platform Method 2: Complements current fieldbus networks Gateway becomes a single node on the fieldbus network, up to 992 I/O points per gateway Reduces the price per point for connecting sensors and actuators Available for DeviceNet, Profibus, Ethernet /IP, Modbus TCP, and CanOpen ifm Controller-e gateway Large Integrated Display Diagnostic LEDs Connection to Fieldbus (Ethernet IP connection shown) AS-i and 24 VDC connections AS-i power supply After selecting the platform, pick an AS-i power supply An integral and required part of an AS-i system Specialty 30 VDC power supply use to couple the master data for transmission over the AS-i cable 2.8, 4 and 8 Amp versions available Provides power to all input devices and modules on the system AS-i power supply Family of I/O modules Choosing the correct I/O module to fit your application Cabinet Compact ProcessLine SmartLine PCB New ClassicLine Airbox Control Cabinet Modules Up to 4 inputs and 4 outputs Analog inputs/outputs available in 4-20mA or 0-10V Solid-state outputs protected against short circuits and reverse polarity Integrated addressing port Inputs to be supplied either by the AS-i network or 24 VDC externally Relay outputs versions available; rated up to 230 V LED indication for short circuit and power DIN rail mount Connection via removable screw terminals, Combicons New ClassicLine Field Modules Mounting technology does not require tools for installation Three directions of rotation for flat cable DIN rail mount Up to 4 inputs and 4 outputs Up to 2 analog (4-20mA) inputs 1 or 2 amp rated outputs available Digital inputs and outputs with LEDs for status indication Integrated addressing port allows setup while connected New ClassicLine Airbox Modules Mounting technology does not require tools for installation Three directions of rotation for flat cable DIN rail mount Up to 4 inputs per Pneumatic module Different valve types include 3/2, 5/2, 5/3 way Digital inputs and outputs with LEDs for status indication Integrated addressing port allows setup while connected Compact Modules Low profile design Up to 4 inputs and 4 outputs per module Fully potted units holds up to harsh environments Increase resistance to shock and vibration High amperage outputs rated for 2 amps Digital inputs and outputs with LEDs for status indication Module base included ProcessLine Modules IP69K protection rating Up to 4 inputs and 3 outputs Up to 4 analog (4-20mA) inputs Quick mounting with only one screw Full 316 Stainless Steel housing Ecolab tested to resistance to common cleaning agents found in the food industries Benefits to Equipment builders Reduces engineering time Reduces BOM cost Easy commissioning for new machines Easy trouble shooting No additional software Benefits to End Users Reduces maintenance cost Easy troubleshooting Easy expansion of existing systems in house Training seminars offered by ifm efector Complete sensor solution provider ifm can also provide your sensing component and cable needs Proximity sensors Cables Photoelectric Pressure Flow Temperature
