In this week's discussion, Tim Cicerchi and Helge Hornis continue their conversation about The AS-Interface Maintenance and Troubleshooting Guide. The guide explains what users can do with the AS-Interface addressing handheld unit. Hints from the guide include:

  • --Assign an address to any AS-Interface module
  • --Read inputs and set outputs
  • --Read the profile (IO and ID codes)

In this week's discussion, Tim Cicerchi and Helge Hornis call out specific aspects of The AS-Interface Maintenance and Troubleshooting Guide. The guide is a very useful booklet that helps new and experienced AS-Interface users during planning, installation, and troubleshooting. Tips include:

  • --Use certified modules
  • --Always follow the most basic installation rules .. there are not that many
  • --Do not use shielded or twisted cable

In this week's episode, Helge Hornis continues his discussion with David Fink, National Account Manager at Pepperl+Fuchs, about controlling and monitoring valve position using AS-Interface in combination with valve position sensors. 

  • --The components that comprise a valve assembly
  • --AS-Interface controls the valve assembly or solenoid valve
  • --How to know if the valve is stuck?
  • --Can AS-Interface control an actuator valve without a solenoid?
  • --Are different manufacturer valves, actuators, and valve position sensors compatible?
  • --Can manually operated valves be equipped with a valve position sensor and AS-Interface?

In this week's episode, Helge Hornis continues his discussion with David Fink, National Account Manager at Pepperl+Fuchs, about using AS-Interface for valve position monitoring.

  • --What is the output of the solenoid driver on a valve position sensor?
  • --Differences between standard sensors with no solenoid output and valve position sensors with solenoid output.
  • --AS-Interface modules and their uses for valve position sensing.
  • --The myth that AS-Interface is only for low current consumption/low wattage types of applications.

In this week's episode, Helge Hornis talks to David Fink, National Account Manager at Pepperl+Fuchs, about how to use AS-Interface to monitor valve position. David first gives an overview of the basic components of a valve assembly. This includes quarter-turn valves mounted to a pneumatic actuator. The actuator is equipped with a dual-position inductive sensor a target or puck, and a solenoid valve:

  • --How does the whole valve assembly work together?
  • --Do you need to pay attention to where the puck is mounted?
  • --How is AS-Interface used to control the position of industrial valves?

During last week's episode, Tim talked about the basic AS-Interface safety monitor. There is a second hardware version that can operate a small AS-Interface network without the need for a dedicated AS-Interface power supply. Today, Tim covers the important points of the VAS/M-2A8L-KE4-8SE-C1 safety monitor.

Products noted in this episode:

VAS-2A8L-KE4-8SE safety monitor

VAZ-1E4A-KE4-Z/R-S contact expansion module

VAZ-2E8A-KE4-Z/R-S contact expansion module

In this episode, Tim and Helge discuss the scenario where engineers are looking for small, flexible, and low-cost safety solutions where AS-Interface Safety at Work may not make sense for their application.

The AS-Interface safety controller VAS-2A8L-KE4-8SE is a low-cost, high flexibility device. The safety controller offers 4 safe inputs and 2 safe outputs and is able to expand if the application requires it.

Other products mentioned in this episode:

Most modern installations use AS-Interface gateways that are Ethernet based.  More specifically this means PROFINET and EtherNet/IP.  These gateways are also available with an integrated safety controller.  Tim and Helge discuss why this integration of the gateway with safety functionality is advantageous.
 
As far as AS-Interface power supplies are concerned, most installations utilize 4 A or 8 A power supplies.  While decoupling can be located in an external device or in the gateway, it is still most common to have the decoupling circuit inside the power supply.

Every AS-Interface system needs three basic components: gateways, power supplies, and modules. Add some infrastructure like cable, and you have what it takes. When it comes to AS-Interface modules, 4-input modules and 4-input / 4-output modules are used the most.

 
Some users even go a step further and design everything using 4-input / 4-output modules. Flexibility in the field and reduced stocking are major advantages. Factory automation uses the AS-Interface flat cable while process automation almost always uses round cable.

Virtually every machine uses e-stops to bring them to a safe, no-power state. With AS-Interface, the most common e-stop is designed so that all the necessary electronics are part of the e-stop.

But there is another approach: combining a more conventional dumb e-stop with a very small AS-Interface G10 safety module. Safety door switches are also very common. To allow the highest degree of flexibility, the keys that go along with these safety devices come in many designs depending on the kind and size of door.
