Do all automation products have to be rectangular? No! The round G11 AS-Interface module family from Pepperl+Fuchs offers unique features that make this the best choice in many tough situations:

  • -- Round design looks great no matter how it is oriented
  • -- Super sturdy mounting base makes this AS-Interface module ideal for tough installations
  • -- O-ring design results in IP68/69K without the need for encapsulation
  • -- Models with M12 network connection add even more mounting flexibility

Most AS-Interface modules are designed for field mount applications and the G12 family of AS-Interface modules from Pepperl+Fuchs is an ideal solution with some very special features:

  • -- Stainless steel M12 I/O connections for harsh conditions
  • -- 100 % tool-less installation for fast mounting
  • -- Mounting base with integrated screw and DIN mount
  • -- Port-specific output overload indication for fast troubleshooting

AS-Interface is frequently used by mounting modules inside of cabinets and junction boxes. Many suppliers offer IP20 devices, but Pepperl+Fuchs' KE and KE1 AS-Interface modules are unique and offer a number of significant advantages:

  • --Color-coded removable terminals speed up installation and maintenance
  • --Versions with electronic and relay outputs add application flexibility
  • --DIP switch selectable AS-Interface/AUX sensor power
  • --Shallow KE1 design is ideal for compact junction boxes
  • --Port-specific output overload indication for fast troubleshooting

In this flashback episode, Tim and Helge discuss how AS-interface power supplies are different in several aspects.  AS-Interface power supplies provide a higher primary voltage and contain the decoupling circuit-enabling data and communication on the same cable.  Tim and Helge cover how to determine the size of the AS-Interface power supply.

  • -- AS-Interface power supply
  • -- Voltage
  • -- Current
  • -- How to size the power supply
  • -- Grounding and ground fault detection

In this episode, AS-Interface expert Tracy Molnar identifies three more topics she frequently discusses with customers.

  • --How large does a system have to be for AS-Interface to make sense?  That depends on a number of details like whether there will be safety or if the PLC offers a low-cost scanner card.
  • --How do you connect to the AS-Interface network?  Most modules can be directly connected to the flat cable. Using G10 passive adapters are another option.
  • -How do you replace a failed safe-input module?  The process is simple but requires an extra step.  It is also important that the safe device must be in the 'released' state.  To see how this is done take a look at our video.

In this episode, AS-Interface expert Tracy Molnar talks about typical customer topics she is dealing with frequently when discussing AS-Interface modules. Her three most common topics are:

  • --VAA and VBA modules and what kind of an address do I need? full address or half address?
  • --Disabling inputs on the AS-Interface G11 analog input module and why a user would be interested in doing this.
  • --Most inputs on AS-Interface digital modules are wired such that connector ports 1 and 3 also give access to inputs 2 and 4.  Use V11 3-wire cables when this is not desirable.

Common Questions about AS-Interface Part II -- Zach continues to talk about three most common AS-Interface topics he discusses with customers:

  • Cabling options including color (black/yellow), chemical resistance, lengths, and higher diameter options
  • AS-Interface intelligent sensors vs. standard sensors with AS-Interface modules
  • ASiMon software is downloadable for free from the website.  This version is ideal for maintenance and service but does not allow any changes to the configurations

Common Questions about AS-Interface Part I - Today, AS-Interface expert Zach Steck talks about the most common AS-Interface questions he is dealing with as an application engineer. Here are the top three topics Zach commonly discusses with customers:

  • Network length and how to extend a network
  • How to replace an (older style) VAA I/O module using a (new style) VBA I/O module
  • What options do customers have in terms of cable that can be used with AS-Interface?

AS-Interface safe coupling -- in the past, situations where safe data had to be shared between separate independent system users used a trick, where a safe output on one AS-Interface network was connected to a safe input on another. Later, the ability to share an entire network between several AS-Interface gateways was added, allowing 31 pieces of safe data to be shared.  Recently, SafeLink was introduced allowing safe data sharing over Ethernet.  This method has many advantages:

  • --Sharing data on Ethernet frees up the shared AS-Interface network
  • --Each gateway can now share 31 safe data points
  • --The total system can use 1922 safe rated devices exchanging 961 safe data points

AS-Interface Safety Code Substitution -- In this episode Tim mentions that AS-Interface Safety at Work is based on the transmission of dynamic data called the "safety code". While the dynamics of the data is required so that the Safety Monitor can determine what is going on at the safe inputs. To simplify diagnostics logic on the PLC, a simple code substitution procedure was introduced several years ago.  The latest generation of AS-Interface gateways with integrated safety controller took this a step further. With this diagnostic code substitution it is possible to:

  • --Know which safety contact is open and which contact is closed (red/green/grey)
  • --Identify if a safety device requires testing (yellow flashing)
  • --Detect if a safety device caused a critical error (red flashing)
  • --See if a device is 'ready", awaiting for instance a RESET (yellow)
