▶ C'mon over to https://realpars.com where you can learn PLC programming faster and easier than you ever thought possible!nn=============================nn▶ Check out the full blog post over at nhttps://realpars.com/as-interface/nn=============================nnAS-Interface is usually shortened to AS-i, and its full title is Actuator-Sensor Interface. It is a simple networking system for devices found out in the field. nnAS-Interface is an intelligent cabling system that is designed to replace the discrete wires linking actuators and sensors with a Programmable Logic Controller or other controlling devices.nnOne of the benefits of using AS-Interface products is that it uses a simple cable system that is easy to wire and easy to operate.nnIt is built for simple device exchanges that operate in a Master-Slave system, where a single AS-Interface Master can exchange input and output data with up to 62 AS-Interface Slave devices, with each AS-Interface Slave device being able to transfer up to four inputs and four outputs at any time, either analog or digital.nnThe cost-saving implications for AS-Interface devices, along with the simplicity for location and wiring benefits means that they are an extremely attractive alternative to more traditional, complex devices. nnThey are also fast. Very fast. In fact, the response time of a Slave device on an AS-Interface is typically much quicker than a single data acquisition cycle of a PLC.nnThe transmissions between a Master and a Slave device on an AS-Interface are predefined and cyclic.nnThere is a simplicity to AS-Interface devices that makes it stand out from the competition.n nThere is no need to program Master or Slave configurations, and no parameters to set. All that is required is that the device ID is recognized by the AS-Interface Master.nnA system built using the AS-Interface typically has three components. nFirstly there is the AS-Interface Master, the head of the network. The AS-Interface Master provides the connection to the higher-level control system. nnNext up is the AS-Interface cable. There are two cables required in an AS-Interface system; a yellow cable to carry the power and data to sensors, and a black cable to carry 24 volts to actuators.nnFinally, we have a power supply unit. nThe unit provides a constant regulated 30 volts DC to supply power to the Master and the Slave devices. nIt also works as a data de-coupler.nnThey can be connected directly to a PLC via an AS-Interface Master in the PLC rack. nnAlternatively, they can be part of a larger subsystem and connected to a Programmable Logic Controller via Fieldbus connection, such as Profinet or Profibus.nnThe range of a typical AS-Interface device is around 100m, or up to 600m with repeaters and extension plugs, making it extremely useful remote locations.nnAS-Interface can also be used in safety systems. “ASIsafe”, or “AS-I Safety at Work” is a standard AS-Interface network, but with special ASIsafe components.nAn AS-i bus system is TÜV-certified up to Performance Level e, or PLe or Safety Integrity Level 3, or SIL 3.nnThen we have AS-i Power 24V. We know that the AS-Interface can carry both power and data on the same cable, so you might be wondering what AS-i Power 24V does differently.nn=============================nnMissed our most recent videos?
